What is fiberglass "cobweb", what qualities does it have, and what is it for? What is a painting glass canvas or "spider line"? Glass cloth wallpaper spider web

Development building technologies facilitated the introduction innovative solutions to create new multifunctional building materials, simplifying work in the construction and decoration of buildings for various purposes.

A bright representative modern building materials with a wide range of functions and a wide range of applications is fiberglass, produced from ultra-thin glass fibers with a diameter of 10-18 microns.

He owes his popularity availability of raw materials and ecological cleanliness its components - quartz sand, clay, limestone rocks and glass scrap in the form of cullet.

The use of recycled glass materials allows you to successfully solve the issues of maintaining the proper level of cleanliness the environment and obtaining relatively cheap building materials such as fiberglass or fiberglass.

The basic raw material for the manufacture of glass cloths are glass filaments, obtained in the process of pulling molten glass through platinum dies.

The production of fiberglass is based on the same principle, which you can read about.

Components of natural origin (quartz sand, clay and limestone) and glass recyclable materials based on cullet.

The addition of cullet to a mixture of raw materials, called a charge, significantly saves material and energy resources used in the production of fiberglass.

By processing one ton of cullet, more than one ton of the main natural raw materials is saved, including the following materials:

  • quartz sand - about 650 kg;
  • soda ash - about 185 kg;
  • limestone - almost 200 kg.

For every 10% of the added cullet mass consumption of heat and electricity is reduced by 3%, since a higher temperature is required to melt the charge, which is completely composed of natural components, than for the charge, which has cullet in its composition.

With the introduction of 40% cullet, energy savings will be 12%, which significantly affects the production efficiency.

In total, about 3 million tons of fiberglass are produced in the world.

Leading fiberglass manufacturers pay particular attention to glass recycling.

The presence of cullet in the number of components of the produced glass fiber reduces the amount of pollutants released into the atmosphere, allowing the manufacturer to save on emission treatment equipment.

You can read about other ways of recycling cullet and their benefits.

Differences from fiberglass

The technology for making a canvas from glass fibers is fundamentally different from the production of glass fabrics:

  • fiberglass is obtained by pressing fiberglass, randomly located under the press;
  • glass fabrics are woven on textile and weaving equipment.

After pressing the fiberglass, fiberglass is formed - thin smooth material without a pronounced pattern resembling sheets of paper.

Glass fiber "inherited" its main properties from raw glass - chemical inertness, resistance to open fire and other qualities that made it one of the most demanded building and industrial materials.

In accordance with the production technology, fiberglass differs from fiberglass by the indicator surface density and functional purpose:

  • the density of the fiberglass does not exceed 50-65 g / m2, which allows it to be confidently used for covering ceilings;
  • the density of fiberglass exceeds that of fiberglass and is 150-225 g / m2;
  • fiberglass is a finishing material for covering walls and ceilings, suggesting subsequent finishing painting; due to the smooth surface, the glass fiber allows repeated repainting without deteriorating the quality of the coating;
  • glass wallpaper is finishing decorative coating, which does not require mandatory painting.

With repeated repainting, the surface quality of the glass wallpaper deteriorates significantly.

This is exactly what it is. very important difference between them and the fiberglass.

Thus, it is up to you to decide what is better to use for painting: fiberglass or wallpaper.

If you plan to repaint the coating several times, the choice is obvious.

You can read more about fiberglass and their differences from fiberglass in the article.

Applications

More than 200 million m2 of glass fiber is used annually in Russia. In construction and industry, it is used in combination with other materials that are selected according to purpose and technical requirements to the final product / object.

So, what is fiberglass used for:

  1. Production waterproofing coatings , in which glass cloths serve as the basis for applying bituminous impregnating compositions (roofing). In construction practice, bituminous coatings are used in the form of roll roofing materials and soft bitumen shingles.
  2. Linoleum production, in which fiberglass is used as supporting frame, preventing shrinkage of linoleum.
  3. Manufacturing, in which fiberglass is used as a reinforcing material for impregnation with binding polymer compounds during the subsequent shaping of the product (boats, containers, etc.).
  4. Construction, renovation and finishing works in which fiberglass is used for:
  • creation of protective reinforced surfaces of walls and ceilings;
  • the formation of the finishing coat of walls and ceilings, subject to subsequent decorative painting;
  • creating a soundproofing substrate in floating floor structures to reduce the level of impact noise.

Soundproof canvas is a multilayer roll material with a one-sided bitumen-polymer coating, which is used as elastic sound-insulating underlay under a cement-sand reinforced screed.

Density varieties

The technology for the production of fiberglass is based on pressing chopped or staple fiberglass, the result of which is sufficient soft and flexible non-woven fabric.

Depending on the size of the filament filaments being pressed (diameter and linear length of the segments) and the method of joining the fiberglass threads in the panel, the surface density of the glass fiber varies from 25 to 450 g / sq. m with a panel thickness of 0.5 to 4 mm.

In accordance with the absolute value of the density of the fiberglass, its operational purpose changes. With the growth of this technical characteristics the indicators of its mechanical strength grow proportionally.

Currently there are three groups glass mats, united by density indicators, a set of functions and a scope of application.

25 to 65 g / m²

They are produced using wet pressing technology, identical to the process of making paper smooth sheets.

The canvases of this group are used to decorate walls and ceilings, for which they are called painting glass fleeces.

More popular name the materials of this vast group have a "cobweb", which they received because of the translucent texture, reminiscent of an openwork woven cobweb.

For writing paper for copiers and printers, the standard areal density within 80 g / sq. m. The density of the "cobweb" one and a half to two times lower than a sheet of paper.

For the manufacture of "cobweb" use glass fibers with a diameter of 10-11 microns with the length of the constituent glass fibers 6-10 mm (used data on painting glass cloth Spectrum SN 30).

For strengthening the structure during pressing modified polyvinyl alcohol is used.

Another name for the painting fiberglass - glass non-woven - stuck with it because of its identity with the painting non-woven, which is a non-woven paper-like finishing material based on glued cellulose fibers.

60 to 200 g / m²

These materials differ from the painting "cobweb" by pressing technology:

  • glass fibers are connected using synthetic resinous components;
  • fibers are unevenly distributed throughout the volume, forming a rough rough uneven surface, while the glass non-woven surface is smooth and soft, and the fibers are evenly distributed, without clots and seals.

Fiberglass of this group has found their application. as waterproofing materials, therefore, they are often called roofing and bituminous fiberglass (depending on the type of binder and its amount).

Outwardly, they no longer resemble a weightless "cobweb", but look like a dense covering canvas with the following characteristics:

  • fiberglass diameter - from 13 to 18 microns;
  • fiber length - 12-18 mm;
  • panel thickness -0.5-1.0 mm.

It should be noted that the roofing fiberglass perfectly absorbs moisture and .

The use of roofing fiberglass is regulated by GOST 30547-97 “Roll roofing and waterproofing materials. General technical conditions ".

The following brands are most popular:

  1. Fiberglass brand Technonikol, produced according to TU 5952-001-13344965-2004. The density of the material is 100 g / m2, the thickness of the panel is 0.8 mm. The glass fibers used have a diameter of 13-16 microns and a fiber length of 12-18 mm.
  2. Fiberglass of the VVG brand, produced in accordance with TU-21-5328981-16-96 with a width of 200, 400, 1000 and 1200 mm. Maximum diameter fiberglass is 18 microns. Panel thickness - 0.5 mm, surface density - from 60 to 200 g / m2, depending on the type of binder.
  3. Fiberglass reinforced with HSA grade, produced according to TU 5952-012-04001485-97. Reinforced fiberglass from competing counterparts (Technonikol and VVG canvases) is characterized by increased mechanical strength due to reinforcement with glass thread in the longitudinal direction along the entire length of the material with a step of 30 mm. The density of the reinforced fiberglass varies from 45 g / m2 (for the HSA-45 brand) to 115 g / m2. m (grade HSA-115). According to the experts of the KhSA significantly surpasses traditional VVG by physical and technical parameters and is a more suitable quality base for the application of modern bitumen-polymer coatings.

Fiberglass is also used to create multilayer bituminous roll materials, of which the most popular glass-insol TU 5774-004-00289973-96 grades K-3.5 (HKP) and K-4.0 (HKP).

The surface density of such coatings is 3500-4000 g / sq. m, since it takes into account the weight of the bituminous mixture and other components of glass insulation.

In the marketing practice of bituminous roofing coatings based on glass fiber, such materials incorrectly called bituminous fiberglass.

450 g / m²

This type of fiberglass is called stitched.

They are produced by knitting and stitching several layers of glass fibers with a diameter of 6-13 microns.

The stitching is carried out with glass threads. The formation of the material takes place without the use of binders.

Scope of stitched glass fibers - thermal insulation building structures and pipeline systems of heating mains.

Accepted name and designation heat-insulating stitched glass mats PSH-T. The thickness of the PSKh-T panel is 2.0-4.0 mm.

Interior decoration

For internal finishing works in residential buildings and public buildings- for children and medical institutions, offices, hotels - painting fiberglass - "cobweb" is especially in demand.

The "gossamer" tears easily until it is glued to any surface.

but after glue impregnation in the process of sticking on a wall or ceiling, its strength is comparable to that of steel, which allows the fiberglass to function as a reinforcing material.

This feature provides the following functionality to the web:

  • strengthening walls and ceilings in order to preventing cracking processes and the appearance of microcracks;
  • increased surface strength, since glass mat even after application paintwork retains mobility and in the process of many years of shrinkage of the walls of new buildings to a sufficient extent withstand shrinkage loads to prevent microcracks from growing;
  • masking of already existing microcracks and hiding defective areas surfaces;
  • alignment surfaces of walls and ceilings for painting;
  • giving specific decorative texture wall and ceiling covering for interior decoration and painting.

Advantages of using in finishing works

The main advantages of the "gossamer" include the following factors:

  1. Increased fire safety a room covered with a painting fiberglass.
  2. Resistant to open flames and high temperatures in the event of a fire in the room - fiberglass can withstand up to 1300 without destruction and does not emit toxic substances.
  3. Valuable environmental qualities- coatings from the "cobweb" do not emit harmful substances and cannot provoke allergic manifestations.
  4. High chemical inertness in relation to corrosion, acids and alkalis.
  5. Absence conditions for education fungus and mold.
  6. Antistatic coatings, as a result of which static electricity does not accumulate on the finished walls and ceilings and dust does not settle.
  7. Fiberglass is not susceptible to impact dampness and condensation.
  8. "Gossamer" does not lose its operational properties with sudden temperature changes.
  9. Good strength qualities maintaining integrity wall covering in houses and apartments with pets;
  10. Possibility of multiple repainting without loss of decorative qualities.
  11. The wall covered with a "cobweb" will not impede the movement of water vapor and air, positively affecting the microclimate of the home.

Summarizing the list of advantages of glass fiber painting as a finishing material, it should be noted that it is fully adapted to modern special requirements for materials for interior decoration of residential and public buildings.

Note the following circumstances at the forefront of the requirements for interior decoration:

  • hygiene coatings, implying the possibility of constant wiping, washing and disinfection;
  • antistatic fiberglass material;
  • bactericidal properties allowing the use of "cobweb" in the wards of clinics, in kindergartens, in swimming pools and saunas;
  • moisture resistance;
  • good acoustic properties in room.

Disadvantages of using

The disadvantages of the "cobweb" include the following points:

  • painting glass canvas by structure is soft and pliable, which makes it very difficult to fix it in one position when pasting walls or ceilings, therefore, it is practically impossible to manage the material alone;
  • the complexity of dismantling the already glued "cobweb";
  • cobweb canvases prevent the spread of small cracks, but simple application on the wall, it is not able to "cope" with the elimination of large defects; when eliminating them, it is necessary to carry out preliminary preparation of the walls and putty, only then stick the fiberglass;
  • painting fiberglass without putty 2-5 times increases paint consumption in comparison with the color of the previously putty "spider web";
  • the need to work in protective rubberized overalls and to protect the organs of vision and breathing in the process of cutting and gluing the fiberglass.

Fiberglass consists of thin glass fibers, which when cutting the canvas break... Micro fragments of glass become hazardous to skin, eyes and breathing.

Types of painting glass cloth

In works on interior decoration, the "cobweb" is used as a reinforcing layer, therefore, the front side of the painting fiberglass has a smooth surface, and the back side has a fleecy and rough surface to improve adhesion to the wall or ceiling.

Depending on the value of the surface density of the "cobweb" material divided into three groups:

Vitrulan's VPP 200 series pigmented fiberglass should also be included in the category of dense painting glass mat. It can no longer be called a "gossamer", since the density of the fiberglass is 200 g / sq. m.

On the front surface The material is factory-applied with a layer of primer paint, and on the glass cloth of the Vitrulan VPP 200 Aqua model, in addition to the “primer” layer, a layer of glue is applied to the wrong side of the panel.

Due to the presence of the adhesive, Vitrulan VPP 200 Aqua can be classified as self-adhesive wall coverings, since when glued just moisten wall without additional application of other glue.

The high density of the canvas allows you to reliably hide wall defects, and the pre-applied paint will ensure even distribution when finishing decorative painting.

One layer of glossy paint is enough for the painted canvas to perfectly fit into the interior of any style.

Algorithm of work on the sticker

When talking about how to use glass canvas painting for walls or ceilings, the following steps should be described.

Stage 1 - preparation wall and ceiling surfaces (hereinafter referred to as the base), including a number of mandatory operations:

  • removal from the base of the remnants of the old finish;
  • cleaning from dust and dirt deposits;
  • sealing large cracks and grooves, leveling protrusions;
  • priming to ensure maximum adhesion of the adhesive to the substrate.

Stage 2 - slicing pieces fiberglass for gluing, including the following operations:

  • cutting the "cobweb" in accordance with the preliminary measurements and approximate calculations;
  • cutting of the cut panels from the roll.

It is customary to cut pieces of material in such sizes that it would be convenient to work with.

Stage 3 - kneading glue. Many craftsmen use their own adhesives, believing that it costs much less.

Of the "branded" adhesives for glass-fleece, practices distinguish brands:

  • Oscar;
  • Wellton;
  • Nortex.

Stage 4 - direct gluing glass non-woven fabric. When pasting rooms to create modern interior the method of the so-called "double cut" is used, which makes it possible to obtain canvases glued end-to-end:

  • first, two sheets of material are glued with an overlap, as shown in the photo;
  • thickenings at the overlap are cut with a knife along their entire length and removed.

Leading manufacturers

On the Russian market, foreign glass fiber manufacturers are dominated by companies that produce not only glass non-woven paint, but also a wide range of other glass fiber products - glass wallpaper, fiberglass, roofing and waterproofing materials.

Among them, the indisputable leadership belongs to the following brands:

  1. Vitrulan (Germany) - produces fiberglass in a wide range of panel density, ranging from 25 to 300 g / m2. For truly "German" quality, buyers of Vitrulan products have to pay high prices - the cheapest "cobwebs" cost at least 2,000 rubles / roll.
  2. Wellton (Sweden) - workshops producing glass canvas painting are located in Finland and Germany. Welton's products are slightly cheaper than their Vitrulan counterpart (RUB 1,500 / roll), but in some cases on the part of users there were complaints due to shedding of the coating.
  3. Oscar (China) is a Chinese manufacturer of Wellton products, since it produces them under its own Oscar brand. The cost of the "cobweb" fluctuates around 1000 rubles / roll.
  4. Nortex produces fiberglass in the Czech Republic and China. In the Russian market, Nortex material is sold at a price of 610-630 rubles / roll.
  5. TechnoNIKOL is a domestic manufacturer, widely represented in the supply of fiberglass increased strength for industrial premises and roof insulation. Roofing fiberglass in a roll 9 meters long costs 669 rubles.
  6. X-Glass is a Russian company that produces glass non-woven linen at the European quality level. While the assortment of fiberglass is not wide, but it attracts users its affordability... Depending on the density, one roll of a standard size costs from 516 rubles. (density 25 g / m2) up to 646 rubles. for material with a density of 50 g / m2.

Which one is better to choose?

When choosing a painting canvas for use in finishing work, they are guided by following circumstances:

  • its purpose (for painting, for paper wallpaper or wall panels, etc.);
  • type of surface - wall, ceiling or floors;
  • the degree of deterioration of the surface;
  • the type of defects to be repaired (cracks, cavities, bulges);
  • the base material on which the fiberglass will be glued - concrete, brick, wood, etc .;
  • Useful video

    From this video, you will learn what a fiberglass "cobweb" is needed for, which one to choose for certain purposes, as well as about the features of pasting walls and ceilings:

    Conclusion

    The use of fiberglass in repair and finishing works effectively solves the problems of elimination of minor defects and irregularities walls, successfully replacing the finishing filler and hardening the surface.

    As you can see, the price for a roll of spider web and other types of this material for painting or wallpaper fluctuates depending on the density, which is determined on the basis of grams per m².

    The growing popularity of fiberglass materials and their availability in the domestic market creates additional incentives for rational use natural resources and glass recyclable materials for the manufacture of such demanded finishing coatings, what are the "cobweb" or fiberglass.

    Now you know more about why you need fiberglass, what density material is better to choose for a wall or ceiling for painting, how it differs from fiberglass, how much it costs.

    In contact with

    Fiberglass has big amount advantages, and therefore is often used in interior decoration. about its features, varieties, as well as how to glue the fiberglass, we will consider further.

    General concept and advantages of fiberglass

    Fiberglass is an environmentally friendly and harmless material that is created on the basis of mineral fiberglass and organic resins. It appears as a continuous non-woven fabric, without a pronounced texture, which has the highest tensile strength.

    Fiberglass, also called painting cobweb, due to its specific surface and soft structure. In composition, it is similar to fiberglass, but it has a number of features that make it different from them. Fiberglass fibers do not intertwine like glass fiber wallpaper, but simply accidentally stick together in a chaotic manner.

    The production of fiberglass is not associated with machine tools; during its production, fiberglass is pressed. This process is similar to the production of paper. Ultimately, the manufacturer gets a very smooth sheet with a minimum density. The difference between fiberglass and ordinary paper is that the fiberglass is not susceptible to moisture, chemicals and mechanical influence, they do not accumulate static electricity and dust, they perfectly reinforce the surface of the walls.

    The similarity of fiberglass to paper is in air permeability, environmental friendliness, harmlessness to health, antiallergic and antiseptic. The difference between fiberglass and fiberglass is the smoothness of the surface, which is subject to repeated painting.

    On plastered walls, in the process of shrinkage or influence high temperatures, the appearance of the finest network-like cracks occurs, which destroy its integrity and become noticeable only when the walls are wet. If such walls are reinforced with fiberglass, then cracks will not appear, and the surface will become clean and smooth.

    Also, fiberglass is used to increase the strength of paint, which is applied to the surface of the walls or ceiling. In this case, the paint acquires new properties, it becomes non-flammable, stronger and more waterproof.

    The main functions of the fiberglass gossamer are:

    • elimination of small irregularities and smoothing of the surface of walls and ceilings;
    • small crack reinforcement;
    • subsequent application of finishing;
    • increasing the strength of the surface on which the fiberglass is applied.

    Among the advantages of fiberglass, the following qualities should be highlighted:

    • fire safety,
    • anti-corrosion,
    • antiseptic,
    • ease of care,
    • air transmission,
    • anti-allergy,
    • does not store electricity,
    • harmlessness.

    Among a large number advantages, there are several disadvantages of fiberglass:

    • it is hard to work with fiberglass,
    • glass fiber will not cover large cracks, they must first be repaired,
    • during its use, special clothing, a mask and a respirator should be used so that small glass particles do not get on the mucous membranes and do not irritate the skin.

    Scope of use of fiberglass

    The use of fiberglass is associated with interior decoration residential or public premises. It is used for decoration and reinforcement of walls or ceilings. Due to the presence of a dense structure, all irregularities are easily masked and paint is perfectly applied.

    The use of fiberglass when carrying out finishing work allows you not to apply the finishing putty of the walls, it is enough to putty them only with the starting one.

    After plastering restored on the walls, they need to be putty, and then treated with soil deep penetration... The type of glue used to attach the fiberglass should be considered based on the manufacturer's recommendations.

    The glue is applied directly to the wall. The canvas is cut off, which has a margin of about eight centimeters and is glued in the vertical direction. It is desirable to mark with a plumb line the place where the pasting will be carried out. The gluing of the subsequent fibers is similar to gluing the wallpaper, they are glued to each other. Use a rubber roller or putty knife to smooth out any unevenness. Excess fiberglass is cut off with an assembly knife. When the glue is completely dry, and this takes from one to two days, proceed to the staining process.

    Due to the fact that glass fiber has a fibrous structure, much more paint is required. To avoid this, you should putty the surface again, but this time with glass cloth. The consistency of the putty must be liquid, and the application is carried out using rubber spatula... Putty, as if rubbed into the fiberglass. This procedure it is carried out carefully and slowly so that there are no minor errors, since after it the staining will be done.

    The advantage of using fiberglass is that in the process wet cleaning, when using high quality paint, the surface does not lose its original appearance for many years. Therefore, this material is indispensable in the process of decorating a kitchen or children's room. Also, the fiberglass does not burn, it passes air well, has antiseptic properties, and most importantly is completely safe.

    Scope of use of fiberglass:

    • production of materials for waterproofing and roofing purposes;
    • production of floor and wall type panels from polyvinyl chloride;
    • reinforcement of polyvinyl chloride;
    • drainage systems;
    • reinforcing base before plastering;
    • in the production of panels, fiberglass gives them a more presentable appearance, improves fire resistance and simplifies their installation;
    • to protect the pipeline system from corrosion;
    • when gluing roofing, to improve its quality;
    • when laying tiles or carpets;
    • in the device of floating floors, for the construction of special soundproofing screens.

    How to glue fiberglass to the ceiling

    Tools for the job:

    • building level,
    • assembly knife,
    • pencil,
    • roller,
    • brush,
    • painting bath,
    • wallpaper spatula,
    • normal spatula.

    Before proceeding to the direct gluing of the fiberglass to the ceiling, it must first be prepared for this process. Preparatory stage work includes the following actions:

    1. Remove from the ceiling old plaster, paint, lime or wallpaper. For these purposes, use a spatula. To remove old wallpaper, you must first soak it with water and wait half an hour.

    2. If the ceiling is covered with a solution of lime, especially if there are several layers of this material on it, it is recommended to clean it with a spatula. Since the adhesion between the fiberglass and the ceiling will be very weak.

    Tip: If the lime ceiling is difficult to clean with a spatula, another treatment option is possible. Using a brush or roller, dampen it with water and wash with a woolen cloth several times.

    3. After cleaning, you should start to close up small cracks and depressions that have formed in the process of cleaning the surface. Before that, it is recommended to walk along the ceiling with a roller with a primer.

    4. It is possible to glue the wallpaper directly on such a ceiling, but it is better if the entire surface is plastered.

    5. When gluing fiberglass to a plasterboard ceiling, you must first seal all the joints and screw caps and make the surface perfectly flat. The putty must be completely dry before proceeding to the next step.

    6. If fiberglass is glued to a layer of insulation, for example, extraction polystyrene foam, then surface preparation also includes filling all joints and dowels with which it is attached to the ceiling.

    How to glue fiberglass video:

    The process of gluing fiberglass includes:

    1. Preliminary cutting of the canvases to be glued into pieces. To easily join the sheets together, leave one centimeter of stock on each segment.

    2. Determine where to stick the first sheet, using a level and a pencil, draw its location. Better yet, make a complete marking along which gluing will be performed.

    3. Pour the glue into the tray and apply it with a roller to the ceiling surface. Apply such a strip so that it is slightly larger than the area where the fiberglass is glued. Use a brush to apply the adhesive to awkward areas such as corners or near the chandelier.

    4. Then place the cut piece of glass mat on the ceiling and smooth with a rubber trowel. Do not press down on the edges so that they can easily join with the next sheet.

    5. The second sheet is glued in the same way, the joint is wiped with a dry cloth, and processed with a wallpaper spatula.

    6. After gluing all the glass fiber canvases, there should be no drafts in the room. This action will allow it to dry faster and adhere more firmly to the surface.

    Painting fiberglass - features of gluing on walls

    The procedure for gluing the painting glass cloth on the walls begins with their preparation and complete cleaning. Then the walls are leveled and covered with this material.

    Consider the step-by-step application of fiberglass:

    • apply a rough starter putty to the surface of the walls;
    • wait for it to dry completely and treat it with deep penetration soil;
    • after the primer has dried, apply glue with a roller;
    • start gluing the first sheet from the corner part;
    • to improve the surface reinforcement, iron it along the edges of the fiberglass with a roller;
    • give Special attention joining two canvases - apply one canvas to another with a gap, and then using a mounting knife, cut the joint and remove the excess fiberglass;
    • the joint must be smoothed with a spatula;
    • when the wall is completely dry, you need to cover the wall with a finishing putty;
    • after it dries, treat the wall with an abrasive mesh;
    • apply a primer and start decorating the surface.

    Tip: Apply glue about one millimeter thick so that it penetrates the wall and spreads evenly over the surface.

    If the fiberglass is glued with high quality and correctly, the walls seem to be perfectly flat. It is an excellent base for finishing decorative plaster... Subject to all technologies, cracks, fungus and mold will not appear on the walls.

    Painting glass canvas

    The option of using unpainted fiberglass is possible, since this material looks very aesthetically pleasing. But, if it is necessary to paint the walls, fiberglass is an excellent material, which, in addition to providing a perfectly flat surface, also increases the adhesion of paint and walls.

    Advantages of using fiberglass when painting:

    • if you need to drive a nail into the wall, the plaster will not fall out of the hole;
    • complete absence of cracks.

    If glass mat is used, which is intended for further painting, it is recommended to use water-based paints. Thus, the material will not lose its properties, and after a while it is possible to repeat the staining procedure.

    Among the choice of paint shades, it is better to give preference to semi-matte. The question of the direct puttying of the fiberglass depends on what type of finish will be applied next. If desired, in coloring and obtaining a smooth surface, the fiberglass must be putty, in otherwise- immediately cover with paint.

    To save on paint consumption, it is cheaper to first cover the fiberglass with a layer of ordinary glue, and then paint it.

    In the dyeing process, the following is used:

    • roller,
    • brushes,
    • winglet,
    • bath.

    The minimum number of layers is two. The interval between them is twelve hours.

    The winglet is used for rolling the seams, as the roller is not able to paint this part evenly.

    2. Be sure to define the front side of the fiberglass, as it practically does not differ from the wrong side. To do this, examine the label of the material.

    3. Use long-sleeved gloves, a respirator and goggles to avoid getting small glass particles on your nose or on your skin.

    4. When gluing fiberglass on plasterboard surface make sure that the seams of this material do not coincide with the seams of the joints of the drywall sheets. Otherwise, the surface will lose its aesthetics and the seams will be very visible.

    5. The optimum temperature for gluing the fiberglass is from 18 to 25 degrees. The absence of drafts is a must.

    6. Start work on the side opposite to the door.

    Fiberglass video:

    If the base for wallpaper is created by weaving fiberglass threads on weaving machines, then the fiberglass spider web is obtained by stamping. The arrangement of the threads in such a canvas is chaotic; they are glued together using organic resins in a random manner.

    The material is produced with various degrees of density: from 25 to 65 g / m2. It is very light, which is why it is called cobweb. The least dense fiberglass is used for finishing ceilings, the heavier one is used for reinforcing wall putty or as a finishing material for painting. Painting glass canvas has no patterns, therefore it is a very good base for repeated painting different ways in order to obtain a smooth surface.

    Scope of use

    The spider web is easily attached to any surface, it is actively used in the process of new construction and for more convenient carrying renovation works... What is fiberglass for?

    1. Due to its excellent reinforcing properties, it effectively strengthens the surface for finishing. If low-quality drywall is used as a leveling material, then the fiberglass will make such a surface strong and reliable. The use of fiberglass does not exempt the use of serpyanka when sealing joints.
    2. Can replace last layer starting filler or completely primary filler, depending on the condition of the substrate.
    3. The use of fiberglass helps to prevent cracks and cavities. Makes conditions for finishing more comfortable.
    4. The cobweb is used as a solid base for painting, if it is planned to make the wall or ceiling smooth, without embossed patterns.
    5. It is very convenient to carry out repairs with fiberglass of those sections of walls or partitions that are covered with small cracks.

    In addition, fiberglass has found its application in the production of wall panels, floor coverings... It is often used in roofing works and to protect pipelines drainage systems and also as one of the components of the waterproofing cake.

    How and what to glue the cobweb

    The process of gluing fiberglass to the surface of the wall and ceiling is not much different from working with wallpaper and depends on the final purpose of using this material. In any case, the basic leveling and rough preparation of the wall or ceiling surface must first be done.

    Next, you need to carry out priming with deep penetration impregnation and then decide what to glue the fiberglass. Correct selection glue is a very important procedure, since the strength of fixation and the service life of the finish depend on the quality of the adhesive. It is worth using only special formulations from well-known brands, for example, Wellton, Pufas, Bostik. They contain high quality components and are completely harmless to humans. Glue for fiberglass, when cured, forms a film that prevents the formation of mold and fungal manifestations.

    The sticker process consists of the following stages:

    • a roll of fiberglass - the cobwebs are unfolded and cut into canvases the right size;
    • an adhesive composition is applied to the surface of the wall or ceiling using a roller, spatula and brush;
    • the first canvas is glued from corner to center, it must be tightly smoothed and smoothed with a plastic spatula;
    • spider webs are glued end-to-end; if it is necessary to make a small overlap, then after sticking it is cut with a sharp knife and the excess is removed in order to strengthen the reinforcing purpose of the material.

    After the surface is completely finished with cobweb, it is covered with a layer of the same glue, only in a diluted state. This formation serves as a good basis for finishing putty or staining in several steps. But by itself it does not create an absolutely flat surface, since the glue easily penetrates between the glass fibers. Now you should wait until the wall or ceiling is dry and you can proceed to further work.

    Final finishing

    Fiberglass for painting can be used immediately after the glue has dried. However, this process cannot be called too simple in terms of labor intensity. You will need to apply several layers of paint so that the surface is completely flat and smooth. Since the first layers of the dye composition will penetrate between the threads of the cobweb, thereby creating uneven dyeing.

    However, you can go the other way - before painting, cover the fiberglass with one or two layers of finishing putty. It will hide all irregularities and save expensive paint consumption. Properly applied fiberglass under the putty will help create an ideal and very durable surface. Protects it from shrinkage cracks and extends the life of the cladding.

    When decorating premises, many do not want to give up such familiar material as paper, vinyl, non-woven wallpaper or some others. At the same time, the question is asked: is it possible to glue wallpaper on fiberglass? If the walls of your house are made of wood, they are PVC panels, composite boards such as chipboard or fiberboard, with the use of insulation, then glass fiber can not only be used, but absolutely necessary. For better adherence of the wallpaper to the surface, reinforced with fiberglass, it must be covered with a putty. After drying, treat with a primer and you can stick any wallpaper. They will hold firmly and serve for a long time.

    When working with glass materials, one must not forget about safety rules. Work with gloves and preferably wear protective goggles and a respirator. This is necessary so that the glass pile does not accidentally fall into Airways and eyes.

    Cracks at the joints of the gypsum board will not appear if you stick the fiberglass under the putty

    It can be very upsetting when, after the end of a long and expensive repairs cracks suddenly appear on the ceiling or walls in those places where the joints pass between sheets of drywall or other facing material. To prevent this from happening experienced builders it is recommended not to be limited to a serpyanka mesh for reinforcing the seams, but to completely glue the surfaces with fiberglass with your own hands.

    It is much easier to glue fiberglass than wallpaper, it takes a little time, but as a finish, you can be sure and not afraid that, due to shrinkage of the house or temperature changes, repairs will soon be required again. Let's find out what kind of material it is, how it "works" and what is needed for its installation.

    Fiberglass

    Fiberglass is a fiberglass non-woven material that looks like a thin blotter. It is produced by pressing, not by weaving fibers. By itself, it does not have strength, it breaks easily, but after gluing to the surface, subject to strict observance of the technology, it forms a reinforcing coating that is very resistant to deformation effects.

    Fiberglass is sold in rolls of 45-50 meters with a width of 1 meter, and may differ in density. He has a facial and seamy side what you need to consider during installation.

    The price of the material is low, depending on the density, a roll can cost from 300 to 1000 rubles. This is not something to save on, as re-repairing as a result of cracking is much more expensive.

    Auxiliary materials and tools

    Of course, the fiberglass itself will not stick to the wall, for this you need special glue and standard set tools:

    • The glue is sometimes supplied with the fiberglass. If this is not the case, buy glue for glass wallpaper - no other, including PVA or a composition for heavy wallpaper, is suitable;

    Note. Calculating required amount glue, multiply the consumption declared for fiberglass by 1.5-2, since fiberglass is highly absorbent. In addition, the instruction requires the already glued canvases to be coated with an adhesive on top.

    • To apply glue, which has a rather thick consistency, it is best to use a wide bristle brush on the surface;
    • It is convenient to smooth the fiberglass with a special plastic wallpaper spatula, which experts call "shark fin";

    Wallpaper spatula and the lines along which it expels air from under the canvas

    • You will also need a sharp painter's knife and a long ruler or wide spatula for joining the canvas and trimming gaps.

    Installation technology

    In the process self repair many questions often arise.

    In our case, the most important are the following:

    • How to prepare a surface for fiberglass reinforcement;
    • How to glue it correctly;
    • Do I need to putty the fiberglass before finishing.

    We will answer in this sequence.

    Preparing walls for reinforcement

    Before gluing the fiberglass to the wall or ceiling, the surface must be leveled with a putty (see Aligning the walls with a putty according to all the rules). This stage can be skipped only if it has already been putty before, the coating is even, durable.

    Small cracks with a thickness of not more than 1 mm are allowed.

    • Large cracks on the plastered surface are embroidered and repaired in several steps with putty or special composition for seams;
    • Joints between sheets of drywall (see How to putty joints of drywall according to technology) and other sheet facing materials, as well as the places of their attachment to the frame are also putty, and the seams must be reinforced with a serpentine;

    • After the “patches” have dried, the entire surface is leveled with a putty and sanded until a flat surface is obtained;

    The cobweb fiberglass has proven itself as a finishing material and helped to get rid of many problems. Today, even in new apartment there are many problems with the repair. Cracks appear on the walls or ceiling, which are very difficult to get rid of. Even if they are plastered repeatedly, they will reappear. The cobweb mesh is designed to change the situation. The popularity of this material is growing more and more. Its use avoids possible problems further. And it is very simple to glue it. The main thing is to do everything right.

    Fiberglass, one of the types of materials for putty or painting. It is a thin non-woven sheet that is pressed from fiberglass strands. It looks like a grid. This material manufactured roll method, one meter wide and twenty and fifty meters long. It should be borne in mind that this material is not intended for fine finishing... Its area of ​​application is to protect surfaces from cracks.

    The spider web has a density from 20 g / m2 to 60 g / m2. For painting, use a mesh of lower density, for reinforcement of a larger one. This material allows you to hide microcracks, and also allows the walls to breathe. The complete naturalness of the material does not violate the environmental situation of the room. When using it, the appearance of fungus is prevented, it does not react with chemicals... Can be used on objects with high humidity.


    Fiberglass spider web gives increased strength to the base and prevents cracking

    Areas of use

    This material can be glued to any surface. It gives increased strength to plaster and putty. If necessary, it can be applied before staining. Very often, a spider web is used before gluing wallpaper. But this can lead to the formation of bubbles, which appear due to the fact that the drying process takes a very long time.

    You should know! The fiberglass has two sides - the seamy side and the front side. They differ in their structure, the front side is very smooth to the touch. The wrong side with villi, it sticks better. Although there is a correct division into parties, if they are confused, then there will be no special consequences. The main thing is to observe the right amount glue and press the material tightly to the surface.

    Glue mixture

    The glue for the "cobweb" should be selected correctly. It needs a special one, which is designed specifically for this purpose. There is no need to try to save money and use other types of glue. This can lead to consequences that could not have been expected.


    The glue is applied thickly, but without frills. It is very convenient that if there is not enough glue, and the mesh is already glued, then you can smear it on top - soak it. Cobweb mix has the following benefits:

    • the glue is completely environmentally friendly;
    • leaves no stains or marks;
    • final setting time - 2 days;
    • does not respond to cold.

    Cobweb mesh drawing rules

    To glue the cobweb, special skills are completely unnecessary. It is important to follow the rules, which are quite simple. But if there is no experience, then it is best to practice a little. Do not take on large volumes of work right away. A little patience, and soon everything will turn out like real masters.

    VIDEO: how to work with fiberglass

    The process of applying fiberglass can be divided into several stages. Much depends on the correctness of their implementation.

    1. The surface on which this material will be glued is being prepared. It is advisable to remove all irregularities, they can cause bubbles. All dirt is washed off with a damp cloth.
    2. The adhesive is applied to the wall or ceiling. You shouldn't feel sorry for the glue, but you don't need to use it a lot either. The fact is that the process of applying the mesh is very similar to wallpapering. The same rules apply here.
    3. A pre-prepared mesh of a cobweb of the required width is applied to the surface. It is best to keep the front and back sides correct.
    4. The fiberglass is well smoothed. If you can't do it with your hands, then you can use a soft cloth. The remaining air is expelled with a spatula. You should move from the middle to the edge. But it's important to be careful. The cobweb can be easily torn and should be avoided.
    5. Anything that sticks out is clipped. The glue is applied again. A well-impregnated leaf turns dark.
    6. The subsequent sheets should be properly overlapped. Drafts must be avoided. Otherwise, all the work will go to waste.

    If external and inner corners are not perfect, then it is best to cut the mesh in these places. Then voids can be avoided. Cracks in the corners must be sealed with tape (paper). This should be done in the places where the walls and ceiling join.

    Fiberglass and drywall

    If the surface is made of plasterboard, it is required preliminary preparation... All seams must be sealed with putty. It is important to know that the joints between drywall sheets and mesh should not overlap.

    Unlike simple walls or ceilings, when the cobweb is glued with an overlap, it is necessary to glue it to the drywall end-to-end. Pruning should also be avoided. If this is not observed, then cracks may form in these places.

    Final stage

    When it is completely dry, and this can take up to two days, you can start filling the surface. If painting is supposed, then it is better to use a fine putty. It should be applied in several layers. Each of the layers must be allowed to dry completely. After that, you can start sanding using a sandpaper. We must not forget that, as with simple painting, the walls or ceiling must be primed first.

    Now more and more often they skip the stage with filling. This is replaced by applying a generous layer of glue. With the help of this trick, it will be possible to reduce paint consumption. It should only be borne in mind that in this case, the mesh structure of the cobweb will be noticeable. It will be impossible to change this even if many layers of paint are applied. A smooth surface will not work.

    Fiberglass has many advantages, but there are also minor disadvantages to consider. When cutting the mesh, small particles of fiberglass appear. Getting on open areas body, mucous membranes, they cause severe irritation. Therefore, work is carried out exclusively in special clothing, respirators.

    But such minor flaws cannot negate the advantages that the spider web has. Its use allows you to avoid many unpleasant moments in the future. In addition, pasting it does not require special skills.
