Reinforced concrete foundation is operated in the ground and needs to be protected from moisture. Foolish waterproofing is an simplest technologynot requiring high professionalism when processing with your own hands. Depending on the plasticizer, filler and the required level of protection of power structures, the consumption of mastic and drying time is changing.

The processing of the bituminous resin 1 m² of the surface is very expensive, the film "flows" in the heat, cracks in the cold. Therefore, modern masts contain components that improve the properties of the material:

• plasticizer - crumb rubber, latex resin, rubber, mineral oil;
• filler - ash, dust brick, quartz, lime;
• reinforcing additives - asbestos, basalt wool;
• inhibitors - Metal corrosion moderators.

Cold (liquid) mastic.

Cold mastic more convenient in work, harden immediately after evaporation of the solvent. Hot waterproofing for the foundation is pre-warmed up to 160-180 degrees, hardening when cooled.

Average consumption with one-layer application with their own hands on 1 m² is:

• hot waterproofing - 2 kg (2 mm film layer);
• aqueous base - 1 - 1.5 kg (film 0.6 - 1.2 mm);
• on a solvent - 1 - 1.5 kg (0.5 - 1 mm film).

Hot (solid) mastic

Under normal conditions (the absence of precipitation, 20 degrees), cold mastic dries 5-24 hours (solvent, dispersion, respectively), hot modifications are frozen in 4 hours. When choosing, what layer is better to apply, than to cover the designs, factors are taken into account:

• terms of work;
• consumption of coating;
• atmospheric conditions;
• price of materials;
• film layer resource.

The minimum allowable outdoor air temperature is -5 degrees for hot products, solvent-based mastics. For the water emulsion compositions, this threshold is +5 degrees, it is allowed to twice the large moisture content of the base (8% instead of 4%).

If the characteristic is important for most paints, then the mastic is much more important for the "dry residue". This property is indicated by most manufacturers on the package, allows you to determine how much substance remains on the surface after hardened. Preferably, waterproofing coats with a dry residue of 60 - 70%, rather than 20 - 40%, as the total consumption of material and labor costs is reduced.

Hot mastic is cheaper, correspond to GOST 2889, but require additional equipment (heating, applying). The main characteristics of the most sought-after waterproofing coats are:

• Bituminous rubber mastic - 25 year-old resource, suitable for inclined surfaces 45 degrees (not slipping when heated), frost resistance -60 degrees, permissible operational heating +100 degrees, antiseptic, coating is flat, heating is not needed.
• Rubber-bitumen coating - Drying - 24 hours, set of strength - 7 days, vibration-resistant film, nervous (stretching 200%).
• Bituminous and oil modifications - cheaper than others, are not afraid of heating, frosts, the film is not formed, the coating is considered self-healing, are not suitable for processing inclined planes.
• The bitumen-latex mastic is suitable for operation from -35 to +80 degrees, reliages the seams of roll insulation reliages, suitable for gluing materials, withstand pressure pressure.

For sealing seams of prefabricated base foundations it is better to use special compositions. For example, waterproofing plaster penetrating mixtures.

Surface preparation

All work work should be made without disorders 3.04.01 (insulation), SP 45.13330 (foundations), MDS methods 12-34, Recommendations of the Individual Institute. To better roll out the material on the surface of the foundation, increase the adhesion during the coating with a brush, it is necessary to produce operations:

• surface cleaning - random solution, remnants of the film, chips from the boarding formwork must be removed;
• inserting technological seams - relevant for the prefabricated ribbons from the FBS blocks, a hydrosponne is used, a sealant or swelling cord depending on the level groundwater (AGB), the presence of pressure pressure;
• alignment - films resulting after hardened by bitumen mastic have high elasticity, therefore it is enough to close only large cavities, to chain the seams with special plasters (moisture-proof modifications).

Waterproofing is obliged to be continuous - any untreated area, a large scratch from stone during the backfill, there is no work efficiency. Therefore, the outer and inner verge of ribbons are processed (if the house without basement), its upper surface.

The vertical layer must be combined with a waterproofing carpet under the basement basement, the edges of which should be released outside before the filling of MZLF. They are glued to the walls of the ribbon, processed the sections of the proceeding / rolled waterproofing 3 - 4 layers of isolation.

Then concrete surfaces The foundation must be treated with special soil. These can be diluted bitumen mastic or polymer primer. It binds dust, strengthens the surface layer, improves wettability, fills the pores.

The characteristics of the material are as follows:

• consumption - 0.2 - 0.4 l per 1 m²;
• drying - 1 hour emulsion, 6 - 12 hours bituminous, 15 minutes polymer.

The material is easily applied with your own hands (brush, roller), increases the cost of the foundation for 7 - 10 rubles / m2 maximum.

Application

Single-component compositions are ready for use, two-component mixtures should be mounted with their own hands according to the instructions on the package. In the latter case, it is necessary to pay attention to the life of the material - immediately after mixing the bituminous base with the hardener, the mixture begins to fit. It is necessary to take into account the configuration of the foundation, the availability of access in all areas, it is realistic to evaluate your own productivity to have time to work out the entire volume.

Applying mastic to the surface.

Depending on the consistency required by the thickness of the layer, the configuration of the belt foundation bituminous waterproofing Applied with spray, roller, brush, spatula:

• recommended nesting strips 5 cm;
• consumption of about 1.3 kg per 1 m²;
• concrete processing from below up.

In the corners, waterproofing is usually rejected by fiberglass.

The next layer of cold mastic is beginning to apply the wet previous one. To improve the quality of waterproofing between layers, the reinforcing layer is usually placed (glass cholester, polymer plaster grid). On the finish coating you can apply large sand, increases the strength of the film several times. Consumption in each subsequent layer is slightly reduced, since the lower film of bitumen mastic levels the wall.

Fiberglass can be used to enhance the corners.

backfilling

Specialists repeatedly resemble the need for a continuous layer of waterproofing. At the stage of reverse backfill, the sinuses of the basement of the foundation, bitumen mastic is easily damaged by stones, gravel. Therefore, it is recommended to use non-metallic materials of a small fraction (for example, sand), additionally protecting the tape from tangential swelling efforts. Consumption will increase, but the quality of the waterproofing film layer will ensure the maximum operational resource

Fully solves the problem of protecting bitumen mastic insulating circuit:

• camping of the outer surface of the foundation tape extruded polystyrene foam;
• the insulation of the scene at the level of 30 - 40 cm from the surface of the Earth.

Budget consumption in this case is fully justified for the underground floor operated. Insulation shifts outward dew point, warning fogging inland walls. However, in the absence of the basement floor, the insulation is often not needed, in this case it is possible to protect the waterproofing by a layer of geotextile.

Tip! If you need contractors, there is a very convenient service for their selection. Just send in the form below detailed description the works that need to be completed and offers to you will come from prices from construction brigades and firms. You can see the reviews about each of them and photos with examples of work. This is free and does not oblige anything.

- This is a black homogeneous fluid, which is a solution of oil bitumen (the temperature of their softening is at least 80 degrees Celsius) in organic solvents. In primer, there are no foreign inclusions or heterogeneities. It does not contain toxic solvents, such as toluene.

Bituminous primer greatly facilitates waterproofing and roofing work. It allows you to reduce the work time of work and improve the quality of waterproofing.

Views.
Bituminous primer is two types: ready for use and concentrated. Before applying, a concentrated primer (concentrate) must be divorced by one of the organic solvents (kerosene, White spirit, gasoline) 1: 1.5 or 1: 2. This saves on its use, when transporting and stored. With the finished primer, you do not need to hold any preliminary procedures, except for thorough mixing. It is fully prepared for use. Such a primer is very convenient in work. The absence of the need for the preparation of primer from the concentrate significantly increases the speed of production.

Application.
The bituminous primer is used to progress the surface (concrete, reinforced concrete, metal, asbatement, wood, porous materials) during waterproofing and roofing works. At the same time, it can be used as an independent waterproofing product and in a complex with other sponsored and self-adhesive roofing materials.

In particular, the Bituminous primer is used to prepare for waterproofing work:

· Rights flat roofs,

· Foundations

· Underground structures and structures,

· Bridges,

· Surface of metal pipelines.

The product is widely used to protect metals from corrosion.

You can apply a primer on concrete, cement-sandy and other rough surfaces. Dusty, porous, uneven surface is processed by a bitumen primer using piping brushes or brushes. This method of application guarantees good impregnation of the base primer, as well as high adhesion with waterproofing materials. The priming of the surfaces with a bitumen primer will significantly extend the life of materials for waterproofing.

To glue the roll materials using the primer, the surface of concrete, reinforced concrete plates, as well as the seams between individual elements, is completely stuffed. Each subsequent layer of rolled material can be glued only three or four hours after sticking the previous one. Rolled materials are glued together (at least 100 mm), while avoiding cross-gluing. The glued cloth is well rolled up with a special cylindrical roller.

Qualitative characteristics.
Bituminous primer has a number of excellent performance:

· High adhesion,

· Fast drying,

· No stickiness,

· Waterproofing qualities,

· Heat resistance,

· Prevents corrosion processes,

· Used as adhesive mastic for sticking rolled materials,

· Can be used in winter,

· It has water-sensing properties.

Provides high adhesion bases with waterproofing material. For average temperature In 20 degrees of heat, the surface treated with a bitumen primer dries in 12 hours.

If necessary, the product can be used in winter, subject to complete cleaning of the working surface from snow, ice, dirt and fragile elements of the previous coating. Before working, it must be dried, and the rolled materials themselves heat in the warm room with an air temperature of at least 15 degrees Celsius throughout the day. Works on the device of rolled roofs using bitumen primer can be carried out only if the outer air temperature is not lower than -20 degrees.

Working conditions and storage features.
In the work of work using a bitumen primer, it is necessary to ensure good ventilation Rooms or work outdoors. The material is suitable for operation if its temperature is above 10 degrees Celsius. If necessary, the working surface and the primer itself can be a little warm up. At the same time, the primer can not be heated above 40 degrees, as well as perform the priming of the surface near the open fire. When working with primer, you need to use protective clothing and glasses to prevent the material from entering the skin and eyes.

The shelf life is 12 months at air temperature from -20 to +30 degrees Celsius. Store primer needed in a dry place protected from direct sunlight.

Bituminous mastic for waterproofing

In the construction world there are many diverse designs and styles, innovative solutions and inventions of highly efficient materials. This is what it does modern house Safe, environmentally friendly and long-term operation. The main problem that developers have to solve is the impact of external factors on the building. The most relevant question is - protection against the destructive action of moisture and waterproofing of buildings. Increased humidity, climatic phenomena, soil water can have a negative impact on almost all building materials, including metal reinforcement. As a result of the absorption of moisture, concrete is destroyed by its integrity, which leads to the development of fungus, mold that can harm human health. But the most negatives may be the consequences of contact moisture with metal structures - corrosive processes resulting from fluid to metal can destroy the integrity of the entire structure. The leader among all means of protecting buildings from moisture is a bitumen mastic for waterproofing, which will be discussed in this article.

Advantages and Disadvantages of Bituminous Mastics

All types of isolation have their own operational and physico-specifications, features of application, pros and cons. Choosing a suitable material, you must take into account all this data. Consider the advantages and disadvantages of using bitumen mastic for waterproofing.

Advantages:

• High elasticity of mastic contributes to excellent adhesion between it and the surface of the material being processed. Due to this, the construction structure is reliably protected from contact with moisture and erosion, which is the consequence of such contact.
• Preventing the occurrence and development of the process of corrosion of metal structural elements, which allows to extend the service life.
• Penetration of mastic in the pores and filling of cracks.
• Protection against the emergence and development of pathogenic microflora - mold, mushrooms.
• Due to elasticity, with a long service life of the structure and under its shrinkage hydro insulating layer Saved integer.
• The speed and simplicity of application of this coating makes it possible to carry out work on waterproofing yourself. These works do not require special skills, the main thing is not to leave unprocessed even small surface intervals.
• Ability to replace adhesive composition on bitumen mastic when installing waterproofing material in rolls.
• The correct selection of mastic for waterproofing will allow working with it in almost any temperatures.
• Affordable cost and efficiency of use.

Disadvantages:

• The process of frozen bitumen mastic for waterproofing takes place for a long time. In this regard, it is necessary to postpone subsequent processes for some time.

Important! This is not a great disadvantage, since a competently compiled work plan will allow at this time to do other processes.

• Low quality mastic over time can rear and crack. It is necessary to carefully choose the waterproofing material, pushing out at all of its cost.

Varieties Mastics for waterproofing

There are many criteria according to which you can divide mastic on species. When buying a material, carefully learn the instruction in which the application technology and information on its composition is indicated. Consider in more detail, which criteria can split bitumen mastics for waterproofing.

Application technology

The main varieties of mastic on applying technology is hot and cold.

Hot

There are many brands of such mastics in the trading network, the main condition for using them is a mandatory heating to a certain temperature. This liquid mastic for waterproofing varies on heat resistance - there is a maximum temperature, to which you need to bring the composition so that you can use as an independent waterproofing or as a glue under roller material.

Hot compounds mainly use professional builders. When working with such material, it is necessary to clearly comply with a specific safety technology and safety rules to avoid injuries. In the absence of experience with hot mastic, refer to the specialists or use cold bitumen mastic for waterproofing.

Important! This type of coating material is mainly used in regions with severe winters.

Cold

Waterproofing compounds of cold applying can also be found different brands. Before use, the material does not require special preliminary preparation, you only need to mix thoroughly.

Important! When working in frost, some types of mastics need to be heated to certain temperatures. For such work, you should choose only qualitative materialswhich are manufactured by proven companies.

Solvent

To bring the mastic to a more liquid consistency, only the solvent, on the basis of which it is manufactured, can be organic solvents or water.

Number of components

You can find the masses of two species - single-component and two-component.

One-component

To use this type of waterproofing, you just need to mix the composition and apply it to the wall surface prepared for processing.

Two-component

Before using such waterproofing, you must connect two components in certain proportions. Prepare the composition should be directly before applying, as it quickly solidifies. In this regard, and work with it quickly. A two-component mixture in a closed state has a longer shelf life and high strength during operation.

Important! High cost and complexity in use does not contribute to the widespread use of such a composition.

Hardening

According to the conditions of solidification, those that remain in the semi-solid state or harden completely are allocated.

Component composition

Depending on the components included in the mastic, you can find a variety of mixtures, consider them in more detail.

Bituminous Mineral Mastic

As part of such a bitumen mastic for waterproofing, cement, asbestos, limestone, chalk, dolomite or quartz chopped into a fine powder can be found. The mass of these components is no more than 20% of total mass composition. Also in such mastic included a plasticizer in an amount of at least 5%.

A plasticizer in cold mastic is a latobe or oil solvent. It does not solidify in air, withstands various hydraulic, vibration and mechanical loads without damage.

Important! Such mastic is better to use for waterproofing parts of the foundation in the recess.

Bitumen rubber mastic

Small synthetic rubber or rubber powder, which is part of such rubber mix For waterproofing, combined with oil bitumen makes mastic more elastic. Plasticizer performs special mineral oil and mineral fillers. The composition is made on the basis of an organic solvent.

Bituminous rubber mastics found on sale (powder form). Before use, they must be poured into the container, put on fire and heat up to the temperature specified on the packaging. The consumption of such mastic, depending on the thickness of the layer, is 1.5-2 kg per square meter.

Important! Such a mastic is one of the most affordable, the service life of the coating is 15-20 years.

Bituminous rubber mastic

Reliable, dense and elastic protective coating from moisture will provide a bitumen mixture for waterproofing with a rubber, which is characterized by good viscosity. Like the previous appearance, it is bred by a solvent if necessary. Each layer dries from 6 to 12 hours. Depending on the thickness of the applied layer, the porosity of the base, temperature and humidity of the environment, the flow rate is 0.75-1.5 liters per square meter. To form a high-quality coating and better clutch with a treated surface, a design is recommended to be a little moisturized.

Important! When working with rubber mastic, it is not required to process the base of the primer.

Bituminous polymer mastic

The water-level bitumen-polymer mastic for waterproofing contains in the composition of one or more modified polymers. The polymer compositions are perfectly protected from moisture building structures, as well as good protection of rooms from the penetration of radon from the soil. Drying period - 6-8 hours.

Important! The absence of organic solvents, as a result, sharp odors, makes it possible to apply such a mixture not only for outdoor wall processing, but also for internal works.

Bituminous Latex Mastic

Like the previous view, it is a water-emulsion composition. Synthesized in the rubber industry - Latex, has improved characteristics. There are one-component compositions that are used in cold form are on sale. They can be used in frost weather, not heated.

Preparation of surfaces to apply the waterproofing layer is to process their primer. To do this, it is enough to dilute the mastic in the water in the ratio of 1: 1.

Bitumen oil mastic

The frost-resistant mixture is ideal for processing any materials. Such waterproofing can be carried out inside and outside of in-depth structures.

The mixture should be breeded by White spirit, gasoline or solvent. Consumption of composition - from 1 to 1.5 liters per square meter.

Bituminous primer

This mixture has a more liquid consistency and is intended to prepare the treated surfaces to apply the main layer of mastic. It is prepared by dilution, depending on the basis, to the desired consistency with water or solvent.

You can apply to the surface with a brush, roller or from a special pulverizer. After application, you need to let dry for 1-5 hours, depending on the basis.

Requirements for waterproofing masts

Durable and durable coating can be obtained if the acquired mixture will meet the following requirements:

• Explore the label by turning attention to the date of production and all the necessary characteristics.
• Uniformity and lack of foreign inclusions. They can create air bubbles and weaken the properties of the material in protected from moisture.
• The composition should be convenient for applying and elastic.
• The absence in the composition of toxic components, which can be distinguished by the substance harmful to humans.
• The heat resistance of the composition for waterproofing the foundation should be at least 70 degrees.
• For good gluing rolled cloths or clutch with the base, the mixture should have high adhesion.
• Any bitumen mastic for waterproofing should be completely waterproof.
• The waterproofing layer after frozen must continue its physicomechanical characteristics throughout the entire period of operation. Pay attention to the operating temperatures that manufacturer indicates.

The main techniques of waterproofing

Create a protective waterproofing layer is easy, but time this process takes a lot.

First stage

Before starting work, carefully inspect the surface for cracks, and if there are such, they need to be sealing:

• Foundation flaws, if necessary, tighten with metal ties, which consist of a reinforcing bands with a thickness of 3-5 mm or a bracket with a diameter of 10-12 mm.

Important! Conducting this procedure must, because if this is not done, the moisture will destroy the concrete, falling deep into the walls, waterproofing will be useless.

• First of all, cracks and recesses need to expand as much as possible. Small cracks are first filled with deep penetration primer, and then filled with a sealant, which is designed for external work.
• To close a big fracture, first it is necessary to fix the tightening elements, handle the primer and then to fill it with a concrete-adhesive or concrete solution to the entire width and depth.
• The brick foundation is recommended first to reinforce the metal grid, apply plaster, only then go to work on isolation. Such processing should be carried out on the entire surface of the foundation.

Second phase

The next step is the primer of the walls with a bitumen primer. The primer consists of a solvent and bitumen mastic for waterproofing. This mixture can be bought in finished form or mix these two components yourself in a 1: 1 ratio.

Important! This process is necessary to strengthen the surface and binding on the surface of the wall of dust residues than is created. good basis To apply the main layer of waterproofing.

The primer fills small cracks and pores, creates a smooth waterproof surface, eliminates excessive absorbability of the material being processed, as a result - reduces the cost consumption of the main composition.

Features:

• Primer (primer) is convenient to apply a brush or brush, as it has a liquid consistency.
• For the comfort of work, the tool can be placed on a long handle.
• Apply uniformly on the processed surface of the primer and leave to sleep for 3-12 hours.

Third stage

After the primer is dry, apply a layer of selected bitumen mastic for waterproofing. You can apply several layers.

Important! Four waterproofing layers alternating with fiberglass protect the walls from any moisture, as well as an additional reinforcement of surfaces. Such waterproofing is called heavy.

Using a trowel or a wide spatula, apply waterproofing to the surface and distribute the wall evenly.

Important! Each layer of applied material should be good, be sure to pay attention to the packaging where the required time is indicated.

Other nuances:

• Use bitumen mastic for waterproofing can also be placed. To do this, after applying the primer, the layer of mastic is superimposed. For better adhesion before gluing the roofing cloths, the layer of mastic is recommended to warm up.
• Cover the dried treated walls of the foundation with thermal insulation material before carrying out subsequent construction work. This material will protect waterproofing From damage.

Working with bitumen mastic in winter

When working in winter time, when the ambient temperature is up to 30 degrees of frost, use bitumen nutritional mastic. Successful work on waterproofing will be facilitated by the implementation of such recommendations:

• If the work does not assume the use of rubberoid and mastic actors the main material for insulation from moisture, the wall surfaced should be warmed up to the positive temperature. To do this, you can use heat guns or gas burners.
• Preparation of mastic for use should occur in a warm room located at a short distance from work.
• During fog, snowfall, rain and high humidity It is impossible to carry out waterproofing work.
• In cases where there is a great need to carry out waterproofing in the winter season, it is recommended to equip special structures - warmly. It is a design of metal or a bar, which is built at the place of work and is delayed with a polyethylene film. Inside such facilities include heating appliances. With the help of warmly, it is possible to achieve the heating of the foundation to the positive temperature. In the process of heating waterproofing mixes You need to use electrical heated mixers.

Important! Do not use open fire to avoid creating hazardous conditions for the life and health of workers.

In winter, the process of waterproofing passes a little differently. In a place where the warm-up is installed, all layers of mastic are applied, then the warmth is transferred further and already in the next site all works on waterproofing are performed. Such processes are called the work of the seizures.

Important! At the occurrence of the warm season, check the results of the work carried out in the winter. All identified defects need to be immediately eliminated.

Types of bitumen mastic for waterproofing, calculation of quantity and application

The house erected with love needs protection, and, above all, from moisture. The quality of waterproofing directly depends on how long the foundation and roof will last. Among the whole diversity of modern materials there is one, providing hermetic seamless protection against water even in hard-to-reach places and on complex surfaces at an affordable price is bitumen mastic.

Nowadays, bitumen mastic is a "cocktail" from a natural bitumen (one of the oil refining products) and synthetic components - modifiers that increase the service life of the coating, clutch with the surface and ease of application. It is suitable not only for waterproofing surfaces of brick, concrete and wood, but for putting out irregularities, filling cracks, gluing rubberoid, membranes. Mastic has such obvious advantages as high elasticity, the ability to be held almost on any surfaces, the absence of cracks and faults for a long time, immunity to aggressive impacts of the medium.

Types of mastik

Modern masts of various manufacturers, having a bitumen, are distinguished by the properties and composition of additives. Main groups:

• bituminous Mastics - Traditional inexpensive Material,
• reznobitum mastic - coating with increased elasticity and resistance to external influences,
• mastics bitumen-emulsion - intended for pre-treatment of surfaces before waterproofing, are also called "primers" (they can be read here), differ in a more liquid consistency,
• mastics Bituminous-polymer - compounds with additives from artificial rubber, plasticizers, solvents that increase the service life and coating quality.

According to the method of applying mastic divided into cold and hot. For coating hot mastic It requires its preloading gas burner or in a special tank, the advantage of cold mastics is that they do not require this time of the price and dangerous operation. However, heated masts are faster and deeper into the pores of the material being processed, they can be recommended in cases where enhanced protection is necessary and equipment for heating is available.

There are single and two-component mastics. The first are completely ready for applying, they only need to mix closely before use. The second require the addition of active composition, after which they begin to quickly harden. The advantage of two-component mastics in a longer storage period is over a year, while it is significantly less for one-component.

The bitumen mastic, intended directly for waterproofing, in its composition has a sealant, which, after frozen, forms a dense protective layer. It can also include antiseptics and herbicides for additional protection of the building from mold.

Bituminous mastic is most popular in the domestic market. russian manufacturersas well as Italian and Polish compositions.

Calculation of quantity

By purchasing bitumen mastic, it is worth taken into account that its consumption varies greatly from the brand, producer and, most importantly, from the material and porosity of the surface. On average, it is 250 g / m.kv. Mastic is applied to improve waterproofing in two layers. Before purchasing, it should be clarified whether the preliminary use of primer under mastic, as well as its additional breeding solvents.

Waterproofing with mastic

Bituminous mastic is applied quite simply without using special equipment. The surface is thoroughly cleaned from garbage and dust, completely sucked, although there are now mastic that is allowed to cover a wet surface. Mastica can be laid on an old bituminous coating if it has retained integrity, metal structures with rust traces. It is dangerous for the integrity of the apparatus waterproofing, sharp speakers and facets, so before work it is necessary to make sure they are missing and remove all the necklaces.

If necessary, 1-2 layers of primer or primer are applied in advance with roller, brushes or sprayers.

For cold mastic is a fairly wide flat brush or roller, or a wide spatula for more dense compositions. You can apply a smell of pouring with subsequent leveling, most importantly, monitor the uniform thickness of the coating. The layers must be solid, the bands must be placed in parallel to each other. If the mastic is applied to the vertical surface, then it is reached upward.

The outer waterproofing of the foundation and the basement is performed by applying 2-4 layers of bitumen mastic with a total thickness of 2 to 6 cm with strengthening the reinforcing grid. The coating thickness depends on the depth of the foundation and the level of groundwater. For walls enough 2-layers. The new layer of mastic is applied only after complete drying of the previous one. Drying time depends on the composition of the agent, temperature and humidity of the environment. The dried layer stops sticking to the hands. Violation of this rule can lead to detachment or worsening of the clutch of mastic surface.

Properly applied mastic will protect the foundation, basement, walls and roof for 20-50 years.

Work with bitumen mastic and primers in the winter season: features and advice

Many are confident that working with bitumen mastic and roofing materials
In winter it is impossible.

This is not quite so. Everything's possible. We will talk about roofing materials in a separate article, and
So far we will dwell on bitumen mastic.

Indeed, for low temperatures It's hard to work with mastic.

Bitumen thick and hardens, begins to crack and, except for problems with
carrying out work, there is a risk of loss of properties of the mastic itself.

The most frequent work from the ones winter - This is a gasket

Processing of the foundation with bitumen mastic with your own hands

By building a foundation, it is necessary to take care of its waterproofing. If you do not protect it from the impact of moisture, it will gradually occur its destruction. As a result, the construction will come to the emergency. To ensure reliable waterproofing of the foundation, it is recommended to use bitumen. It is sold in construction stores in the form of mastic. Its flow is very economical, it will be possible to perfectly protect the foundation of the house for many years.

Before processing the foundation, the hydrophobizer on the surface must be touched by an antiseptic.

The main advantages of bitumen mastic

The processing of the foundations bitumen was widespread, because such a waterproofing material has many advantages. The most important advantage is that mastic is characterized by high elasticity. Due to such an important characteristic, the material provides a reliable grip with moisture-protected surface. As a result, after drying, the bitumen mastic does not crack. It remains solid for a very long time.

Another advantage is low cost. Due to this, it will be possible to perform waterproofing the foundation minimal costthat will reduce the cost of building a house as a whole.

The use of bitumen mastic provides the following results:

Properly insulated foundation is the protection of waterproofing at home, as well as reducing heating costs in the winter.

• suppression of the emergence of corrosion foci;
• effective protection of the construction structure from moisture effects;
• increasing the life of buildings elements several times, with full preservation of their functionality.

Mastic itself is the composition of the homogeneous mass. Its main components are modifiers, solvent and bitumen base, which is a by-product of oil distillation, remaining after the production of fuel oil, diesel fuel, kerosene and gasoline. In addition, antiseptics and herbicides can be included in the mastic.

Offered bitumen for waterproofing foundations in a wide range. Finding the appropriate composition in accordance with its requirements is easy.

Bituminous Mastic Application Technology

The processing of the foundation of bitumen mastic should be made in several stages. It is necessary to clearly follow the technology, then the result obtained will justify the expectations.

Bituminous mastic is excellent for waterproofing the foundation.

It will be necessary to carry out waterproofing the following:

• bulgarian;
• construction Fen;
• cement mortar;
• soft soil;
• primer;
• mastic;
• brush or roller;
• putty knife.

Stage 1: Surface Preparation

Begin to carry out waterproofing with bitumen mastics, it is necessary from the preparation of the base. It is necessary to pay attention to its surface. If it is noticed that it has a large number of Shells and bubbles, then it will be needed to be lost in fine cement mortar, which is prepared from special dry mixtures. If you do not carry out such work, then the freshly mastic layer will begin to burst. As a result, the waterproofing of the foundation will become poor and will need to produce it again.

The presence on the surface of the base of the so-called scallops, which possess sharp protrusions is also unacceptable. They will need to be removed. To do this, take a baccoon with a suitable nozzle and walk with it on the basis. At the same time you need to treat the corners of the foundation. They must be cut in the form of chamfer or they can be simply a little rounded (radius from 3 to 6 cm). Where there are transitions in a horizontal to a vertical surface, it will be necessary to arrange fillets (cartoons), they will provide the required smoothness to interfacitate the elements.

To reduce the flow rate of bitumen mastic, it is necessary to carry out the primer of the surface of the foundation.

After such work, it is necessary to carefully clear the foundation from dirt, dust and construction garbage. Then you need to take care of the decrease in the moisture content of the waterproof surface. A construction hairdryer will come to the rescue. They will need to add all the foundation. If this is not done, then the mastic can appear and continue to completely detach.

To be confident that the foundation is sufficiently dry, you can make a simple test. Polyethylene film (1x1 m) should be taken and put it on a prepared basis, after which it must be left for 24 hours. If, after this period, it will not appear condensate under it, then you can safely apply bitumen, if it is present, you will need to more thoroughly dry the surface.

Time by the expiration of mastic working surface ready for full exploitation depends on different conditionswhich, one way or another, affect the drying of bitumen mastic. Also significantly differs the speed of drying the mastic depending on the various additives and the foundations of its production.

Those external factors should be listed, the independent impact of which affects how much hissing bitumen mastic:

• The thickness of the layer applied to the treated surface of the mastic;
• Ambient temperature and its level of oscillation;
• Air humidity level;
• The presence or absence of direct sunlight;
• The type of material from which the surfaces are processed.

Holding and taking the final consistency mastic depends on the evaporation rate of the chemical solvent, which is contained in this waterproofing material.

Building bitumen mastic manufacturers declare average drying time From one day to 3. Various technological features in the manufacture of this material affect this period.

Ways to accelerate mastic drying

In practice, there are cases when the shortage of time for construction work does not allow a long time to expect when the mastic dries. In this case, experts resort to fairly simple, but efficient ways Accelerating this process.

Thus, for the operational evaporation of the solvent as part of mastic, when it is applied, gear spathers are used. The layer of mastic applied in this way, due to the presence of furrow, and therefore an increase in the area of \u200b\u200bevaporation, dries up much faster without significant losses as the result obtained.

After applying mastic on the processed surface, it is necessary to isolate the place of work from the possible ingress of moisture to the surface and protect against mechanical damage. This will ensure uniform drying of the layer without drops of its thickness.

In the case of processing objects or surfaces that are not outdoors, and in the room, you can apply various systems Forced heating (thermal guns, heaters, etc.), which will greatly accelerate the process of drying the mastic. However, in these cases it is important to comply with the rules of fire safety and maximally exclude the possibility of finding people in this room, since the allocated pairs can cause significant damage to human health.

It should be noted that also the duration of drying the mastic can affect the storage period of this material in the package.

Drying time of various types of mastic

Despite the fact that bitumen mastic are produced in one state standards, the time of their drying may differ. This indicator, in addition to the above external factors, may also affect the presence of various foundations, additives and impurities in the mastic. For example, a revincible mastic, which is mainly used in the field of car repair, has a shorter drying period, which can be from 12 to 24 hours. Bituminous rubber mastic brand "Universal" has a longer duration of drying - 24 hours.

One of the most popular grades of waterproofing mastic "Hydroizol" dries out 24-48 hours after applying it. Mastics of the brand Tekhnonikol freeze in 24 hours After processing them surfaces.

The time, after which the work surface treated with mastic is ready for full exploitation, depends on various conditions that, one way or another, affect the drying of bitumen mastic. Also significantly differs the speed of drying the mastic depending on the various additives and the foundations of its production.

Those external factors should be listed, the independent effect of which affects how much bituminous mastic dry:

• The thickness of the layer applied to the treated surface of the mastic;
• Ambient temperature and its level of oscillation;
• Air humidity level;
• The presence or absence of direct sunlight;
• The type of material from which the surfaces are processed.

Drying time of various types of mastic

Despite the fact that bitumen mastics are produced according to unified state standards, the time of their drying may differ.

This indicator, in addition to the above external factors, may also affect the presence of various foundations, additives and impurities in the mastic. For example, a revincible mastic, which is used mainly in the field of car repair, has a shorter drying period, which can be from 12 to 24 hours. Bitumen-rubber mastic brand "Universal" has a longer duration of drying - 24 hours.

One of the most popular grades of waterproofing mastic "Hydroizol" dries 24-48 hours after its application. The masses of the brand Tekhnonikol are frozen within 24 hours after the surfaces of the surfaces.

Oil bitumen for a long time was the only material for waterproofing building structures - Roofs, basements, pipes and concrete trays.

Low cost and good operational qualities provided it with widespread use in construction.

However, in its pure form, the bitumen cannot be called a good waterproofer. The reason is that after cooling, the bitumen film cracks from low temperatures, and under the action summer heat Begins to flow.

Therefore, construction science has conducted a constant search for additives that eliminate these flaws.

The result of numerous experiments and inventory tests was the roofing bitumen mastic, which includes a plasticizing substance and mineral supplements in addition to the main binder.

As components that prevent bitumen cracking, Latex, rubber, oil and rubber are used today. In addition to them, various mineral substances are introduced into mastic based on bitumen resins: basalt cotton wool, asbestos, ash, lime, crushed quartz or brick dust.

Fillers reinforce the waterproofing, increasing its crack resistance and hardness, and also save the main binder. In addition, the use of bitumen mastic to protect metal structures requires good anti-corrosion qualities. Therefore, inhibitors are added to the composition of modern bitumen compositions - substances that slow down iron corrosion.

Classification of bitumen mastik

1. According to technological features of application

Depending on the temperature range, in which the bitumen is softened and hardening, distinguishes the masts of hot and cold applications. The first before applying is heated to +160 C. bitumen at this temperature goes into a plastic state, and after applying the insulated surface is hardening.

In cold mastic, bitumen is mixed with a solvent. Therefore, it does not need heating, but hardening after evaporation of the solvent.

By the method of preparation, bituminous mastics of cold hardening are divided into:

one-component

two-component

Single-component bitumen mastic for waterproofing the foundation can be used immediately after splitting capacity.

It is convenient for work, but not for storage. Opening such mastic, it needs to be fully developed. Otherwise, it hardens and become unsuitable for applying.

Production and implementation of bitumen building materials: bituminous mastic of all kinds. Prices, features, types and description of mastic.

The two-component composition must first be prepared by adding the thickener to the bituminous composition and mixing the components well. It takes time, but avoids unjustified losses. It is also important that the shelf life of two-component mastics is several times more than one-component.

2. By type of elastic additives

Depending on the type of additives that improve the elasticity and strength of mastic, GOST divides them to rubber-bitumen, polyurethane-bitumen, bitumen-latex, bitumen and bitumen and oil.

Each of the listed compositions is the same bitumen-polymer mastic, properties and method of application of which are not significantly significant. Rubber and rubber, latex and polyurethane create a homogeneous waterproofing coating, eliminating the two main lack of oil bitumen - fluidity at high temperatures and the formation of cracks at low.

Bitumen mastics are distinguished by the strength and elasticity of the film formed, as well as the temperature regime of operation.

For example, bitumen with polyurethane or rubber is a record holder of elasticity. Formed by him protective film It may increase the initial length almost 20 times without forming breaks.

An exception is a bitumen composition containing an oil solvent. This is an unscruiting mastic. It is ideal for insulation of underground communications subject to continuous impact of groundwater and vibratory loads.

The adhesive bitumen and oil mastic does not form a rigid film, so it does not crack and retains the integrity of the insulation.

This one-component mastic is not afraid of frost to -50c and withstands heating to + 80c. However, for roofing works where a durable protective membrane is required, it does not fit. Here are the bitumen and polymer compositions that are hardening in air.

Elastic rubber-bitumen mastic previously used for automotive bodywork. It firmly curl with any surface (even open metal), not afraid of vibrations, blows and stretching. Temperature mode Its use is very wide (from -40c to + 100 ° C).

You can work with rubber-bitumen insulation on any surfaces: wood, metal, concrete and brick. Like other bitumen masts, it can be used as a basis for sticking rolled waterproofing. It dries around 24 hours, and the maximum strength is gaining in 7 days.

Similar in its properties, cold bitumen rubber mastic, which has high operational and technological characteristics:

• Does not require fireworks
• Optimal for processing complex profiles, joints, adjoints and transitions of different surfaces
• Forms homogeneous and smooth coating
• Biociden and antiseptic
• It has high heat resistance (up to + 100 ° C), frost resistance (up to -60c) and adhesion to the inclined surface (to an angle of 45 °)
• Life service reaches 25 years.

Bitumen rubber mastic can be used for small and mid-repair roofing, waterproofing concrete containers, basements, bathrooms and balconies.

Inexpensive bitumen-latex mastic is produced by mixing the oil bitumen with a synthetic rubber emulsion (latex). It is easy to apply, well held on the basis, resistant to water and aggressive substances. Elasticity in this waterproofing is preserved to the temperature of -35 C, and the fluidity is observed when heated above + 80s.

Latex mastic composition is applied without preheating. They can be isolated any kinds of building structures, as well as glue Ruberoid, Phaneur and insulation.

Application technology

All appliances based on oil bitumen are applied in two ways: manual and mechanical. Manual is used for small insulation volumes, and spray compressors are used to process areas measured by hundreds and thousand square meters.

Preparation of the surface for all mastic is the same: it should be cleaned from dust, peeling layers of old coating and garbage. Cracks are carefully close, after which the surface is dried and covered with primer (primer). This primer composition is sold at a finished form or is mixed on a platform from mastic and the solvent corresponding to it.

Some species of modern bitumen mastics do not need to dry the foundation. This moment the manufacturer separately stipulates the instructions.

Mastics are applied with wide flat brushes, sprayers, spatulas or rollers, controlling the uniformity of the thickness of the insulation. The bands are placed in parallel, with a small "overlay" (5-10 cm).

After drying the same layer, the following is applied. For waterproofing roofs, pools and basements, from 2 to 4 layers of isolation are used, strengthening them with reinforcing fiberglass. For vertical walls (applying is lowered up), there is usually enough 2-layer coating.

The consumption of bitumen and rubberobitume compositions depends on the type of work and the number of layers. With the sticker of the runneroid in one layer, it ranges from 250 to 800 grams per 1 m2. If the mastic is used as the main material for a multi-layer roof, then its flow rate with a thickness of 10 mm on average is 16-18 kg / m2.

For single-layer waterproofing of building structures (basements, walls, tanks), it will be required from 5 to 7 kg of bitumen-latex mastic mixture. If we are talking about new roofWhen 3-4 layers of mastic reinforced with a mesh are applied to the surface, then its consumption increases to 12-14 kg / m2.

Bituminous and oil mastic for processing one square meter of surface surfaces is required from 1 to 1.5 kg. With a two-layer applying, its flow rate increases to 1.5-3 kg.

Manufacturers and Approximate Prices

The most large domestic companies producing a wide range of bitumen mastics of various purposes are Tekhnonikol, Grid, Rusmontolitis and "IPC" CRZ ". They produce products of stable and predicted quality, which fully complies with the requirements of GOST.

The average price of a standard 19-kilogram bucket of bitumen-rubber and bitumen-rubber mastics, depending on the manufacturer and the sale region ranges from 1600 to 2000 rubles.

Bituminous latex mastic is essentially cheaper and its price is in the range from 1000 to 1200 rubles per bucket (19 kg).

Behind the bucket of bitumen and oil mastic hot application, sellers are asking from 700 to 900 rubles.

Cold applications

Bituminous polymer universal

General:

Masty MBH-y (Tu-Tu-2384-001-24237882-01) is a one-commercial, universal, multifunctional, ready for use in a cold form, means. It is a steady, homogeneous solution of oil bitumen modified by polymer additives, in hydrocarbon solvents with mineral filler.

Mastica is comfortable to apply to the surface with a brush, spatula or rubber mop. When dried on the surface, an elastic rubber-like polymer smooth black coating is formed.

As a result of the introduction of bitumen-polymeric masts of the cold application of the MBH-y brand, the use of hot bitumen is excluded at the facilities, which greatly simplifies and hesitates work, improves the working conditions of roofers, islers and parquetrs, improves the safety of the work.

Guidelines for use:

Clean the surface from the dirt, the remains of the old coating, loose plastic rust (mechanically). The remaining rust is recommended to be treated with rust modifier.

Thoroughly mixed mastic apply with a spatula, brush, roller or spray gun for viscous compositions. Apply with layers with a thickness of no more than 1.0 mm.

For gluing with a well-prepared smooth base, one layer is sufficient. For waterproofing and device of mastic roofs, you must apply 2-3 layers. Each layer is applied after drying "to turning" (~ 2-3 hours at T \u003d 20 ° C) of the previous layer.

The final drying is at least 24 hours. At low temperatures, drying time increases.

Work with mastic is allowed at a temperature not lower than -10 ° C. With a negative temperature, mastic is recommended to heat up to +30 ... + 50 °.

In the event of a thickening or when applied with a sprayer, wept White-Spirit "Wellux" or "AutoNOL", by other organic solvents. When mastic gets into the paint coating is to immediately remove with a vein moistened with a gasoline or solvent.

SAFETY REQUIREMENTS:

The mastic Bituminous polymer is a fire-hazard and explosion-proof products, which is due to the properties of solvents included in its composition.

Bear from fire!

When masting a bitumen-polymer in the eyes, they must be rich with water abundantly.

When entering the stomach, rinse it with 2-5% soda solution, cause vomiting and provide abundant drink. In any case, consult a doctor. If you get into your hands, it is necessary to wipe with a rag, moistened with gasoline or another solvent, and then wash with water.

Transportation and storage:

The bitumen-polymer mastic should be kept in a hermetically closed container, indoors intended for storing flammable materials at a temperature of minus 15 to plus 30 ° C.

The waterproofing mastic has recently appeared, but every year it is applied more and more. This is due to the simplicity and ease of application, which significantly reduces the time of arrangement of the structure of the structure. Attractive is the price of material that is acceptable to all segments of the population.

What is mastic, bituminous use? What is the fundamental difference from the material that is pre-heat before use? Before you choose a mastic suitable for insulating work, you need to figure it out in its characteristics and properties.

General information about the material

Bituminous mastic - a material with high plasticity, its basis is bitumen (black resin, solid). Previously, the mixture from bitumen had to warm up before use.

This caused some inconvenience, since the time of the arrangement of waterproofing works increased, besides, these works are firewood. Therefore, manufacturers have developed innovative Materialwhich can be used in waterproofing works with a cold way.

As part of the mastic, solvents are present, which support it in a liquid state. According to the principle of application, such compositions are comparable with paint - as soon as the material falls on the surface, the diluent evaporates and the composition is hardening, forming a high-quality insulation layer.

Types of compositions

Bituminous mastic for waterproofing cold application are divided into two types:

• mixes are ready for use, solvents are present in their composition. You can work with such material in any weather, even in the cold season. These compositions dry out in 24 hours. But the material acquires its properties after a while, usually takes 1 week. This type of mastic is carried out for the insulation of the roof, however, the use of material based on the solvent is quite common and it can be applied on any surfaces;
• water-emulsion mastics that are not smell produced on the basis of water. The compositions are environmentally friendly, they are used indoors for insulation works in the bathrooms and kitchens. Drying time in these compositions is several hours. There is a small disadvantage of the water emulsion - it does not tolerate negative temperaturesEven during the storage period.

Modifications of compositions

Depending on which components, besides bitumen, they are based on mastic, they are divided into subspecies:

• Not modified - in coatings there are no improvement in components, such as polymers. Professionals do not recommend using this material when arranging roof waterproofing, but for other designs it is perfect. But it is worth remembering that such mastic is not used in case of severe temperature drops and if the design is heated.
• Bituminous polymer - roofing, modified mastic. This material is not terrible high temperatures. Positive is the fact that it qualitatively increases the adhesion between the rolled material and the surface.
• Mastic, bituminous rubber - in which rubber crumb introduced. This type of solution is used for isolation of metal structures, as it has anti-corrosion properties. But for roofing work, this material does not apply.
• Rubber mastics based on bitumen - liquid rubber. Composition with increased elasticity, and excellent mechanical and physical properties. The most appropriate composition for arranging roof waterproofing.

When conducting waterproofing works by any materials, you need to carefully prepare the surface - remove dust and dirt, degreased if necessary and dry. After that, put a bitumen primer on the plane, which will improve the quality of the work performed.

All bitumen coatings are divided into several types depending on the number of components:

• one-component - ready-to-use mixtures;
• two-component - mix before applying with hardener.

The characteristics of this material are very high, as the compositions refer to professional. When mixing mastic, you need to strictly follow the instructions from the manufacturer and comply with the proportions. If you put a hardener, more recommended, the lifetime of the composition will be much smaller, and it will be spoiled.

Quality compositions

In addition to the fact that cold bitumen mastic reduces the time of waterproofing work, and is easy to use, as it was written above, it has great amount Positive sides:

• you can get the composition of any thickness, it is enough to add a solvent;
• durability - a modified composition may stop more than 25 years, while not losing its insulating properties;
• universality - any surfaces can be treated with bitumen mastic;
• easy to use - the composition can be applied independently with the help of the cell, roller or tassels.

Like any material, waterproofing mastic has drawbacks:

• price - if we consider mastic for waterproofing, polymer bitumen, then their cost is significantly different at higher side;
• in contrast to the mastic on a bitumen basis, the hot way, this material gives a stronger shrinkage that as a result increases the consumption of isolation.

The consumption of mastic on 1 m2 of waterproofing depends on the method of application, for example, with applying the adhesive layer, 1 kg of composition per square is sufficient. If you create a full-fledged insulation with mastic, then up to 5 kg. Knowing these parameters are very easy to calculate how much material will take.

Where mastic applies

The use of bitumen mastic, as a rule, occurs in the following cases:

• The composition is used when installing soft tiles on the roof, or roll material. It is justified by its use in the repair of the capped roof, and the construction of a soft bituminous roof.
• Waterproofing of the bases of buildings. Using rubber mastic, an insulating layer is equipped with a pile foundation. The remaining types of compositions can be used as horizontal or vertical waterproofing. Inside the building and outside.
• Waterproofing floor. Mastics are used under a rough tie, or under bulk coat. You can isolate plates on loggias in basements, garages. It is often used in bathrooms, toilets, shower.
• Insulating works on terraces and pools. For this, the liquid rubber is well suited, which is applicable for any surfaces.

The use of these compositions is justified, even despite the considerable cost.

Mastics do it yourself

Some private developers wonder how to cook a bitumen mastic with their own hands to reduce the cost of construction. First of all, the ingredients should be purchased:

• bitumen;
• plasticizer;
• filler.

The components are acquired by B. necessary quantityIt depends on which area will be covered with isolation.

Suppose we need 10 kg of material, for this we take:

• bituminous resin - 8.5 kg;
• filler - 1 kg;
• plasticizer 0 0, 5 kg.

The filler can serve: sawdust, rubber crumb, wool mines or asbestos. For plasticity add kerosene or workout.

Before putting bitumen in a container with thick walls and put on fire, it is necessary to grind it well and mix with the filler.

Capacity should be large. Since when heated, the composition will increase in size.

The temperature should be no more than 190 degrees, as the bitumen has a detect property at high temperatures. If bubbles of yellow-green begins to appear on the surface, then this is the first sign that the temperature is too high.

At the right temperature, bitumen mastic should be welded homogeneous and plastic. Plasticizer and filler need to be added gradually and with constant stirring. If foam appears on the surface, it must be immediately removed.

Once all ingredients are introduced into the composition, the material is ready. The composition created by their own hands no more than a day is stored, while it is necessary to apply it when the composition cools up to 120 degrees.

Bitmom primer do it yourself

Before applying the mastic to the surface, it should be not only prepared, but also to cover the primer - the primer based on bitumen. The soil will help increase adhesion, and will make waterproofing much more reliable and better.

The composition of the primer prepared independently - gasoline and the bitumen of the proportion of three to one.

How to cook

• in order for the soil to get high quality, you need to heat the bitumen to 70 degrees and pour it into gasoline;
• bitumen is introduced into gasoline with small portions and stirred to complete dissolution;
• as soon as the soil is ready, the composition is filtered through a metal mesh.

Thanks to these instructions, you will be able to save money on purchasing a finished material.

How to choose

On the market at the moment there is a very large selection of this type of material, and to buy exactly the one that is needed for your structure, you need to carefully examine the characteristics of the compositions. Visit the specialized forums on the Internet, see what people write, who have already used bitumen mastic for waterproofing.

In production, mastic is poured into the container hot, because the five-liter bank weighs five kg, then it is not worth buying this material - it is not high quality.

Tips for beginners to work with sugar mastic.

Tips for working with mastic

Why sometimes through sugar mastic coating, begins to shine the base?

Any variants of sugar mastic, which is used to cover the cake, are very sensitive to humidity, so it is necessary to take care of a cake covered with sugar mastic from moisture.
First, it is necessary to use dry biscuits, oil cakes or purchased biscuits as a base.
Secondly, it is not necessary to dilute too much, impregnating the cake with sugar syrup or liqueur.
Thirdly, a cake, covered with sugar mastic, should be stored in tightly closed hermetic boxes or polyethylene packages.

How long can the cake covered with sugar mastic?

If the cake is wet, then you will need more time to dry the cake
If the cake is very dry, then there is a danger that in two days a mastic, which is covered with a cake, will be swollen.
It also must be borne in mind that in a dry and hot climate, the shelf life of a cake covered with a mastic is less than in a cool and wet climate.

Why is sugar mastic?

When rolling sugar mastic, it is worth considering that its thickness should not be very thin. It is enough to roll out the mastic to a thickness of 2-3 mm.
In addition, during a cake coating, a finely rolled mastic can be broken, all irregularities of the cake base are visible under finely rolled mastic.

On what basis to roll off sugar mastic?

There are several options for rolling mastic.
1) Sugar mastic can be rolled on the table, sprinkled with powdered sugar or starch
2) Sugar mastic is comfortable to roll between two large polyethylene sheets, which are lubricated with vegetable oil.

The advantage of the second way is that it is not necessary to separate the mastic from polyethylene to cover the cake. After the mastic is rolled to a thickness of 2-3 mm, it is enough to remove top sheet And transfer mastic on polyethylene to the cake and only if the mastic already covers the cake, separate polyethylene from mastic.

At the same time, I did not get the smooth surface of the mastic, because I used the thin polyethylene, which when rolling went and formed folding. But I liked the resulting "structured" surface of the mastic, so I did not take polyethylene thoroughly.

I think polyethylene, which is used for greenhouses, will allow you to get a smooth surface, as it is sufficiently dense, in order not to form a fold when rolling the mastic through it.

How to make sugar mastic on a glitter cake.

So that sugar mastic on the cake gloss, after you have finished decoracing the cake, cover the mastic with a solution of honey in vodka in a 1: 1 ratio.
To do this, take a soft bruster and wetting it in solution, apply a honey-vodka solution to your creation. After a few minutes, vodka will evaporate, and your cake will become brilliant.

How to keep mastic and how much?

Any sugar mastic can be stored for several days, up to a week, in well-closed polyethylene packages or plastic containers.

There is nothing to spoil in sugar mastic, it is important to simply protect the mastic from the air so that it does not fall asleep and from moisture to make the mastic not soak.
