Unlike the wallpaper from the usual sheet material, liquid wallpaper would be more correctly attributed to decorative plasters. The reason for this is the similar way they are prepared and applied to the surface. As in the case with plaster mixtures, this finishing material must first be kneaded in a certain volume of water. At the end of the swelling period, the working mass is applied to the wall in a thin layer using a spatula or spray gun. Given the high cost liquid wallpaper, you should find out in advance how to calculate how much material you need for repairs, so as not to purchase too much. It will be easy to calculate if you know the flow rate of the mixture per 1 square meter(sq. m.) walls.

The amount of material to cover a certain area

To find out how much liquid wallpaper is needed per 1 sq. m., special efforts does not need to be attached, since this information is usually found in the user instructions placed by the manufacturer on the outer surface of the package. When applying the mixture to the wall with a spatula, its consumption per square area averages about 250-300 g of dry matter. Depending on the manufacturer, the bag may contain 1 kg or a little more dry material. Thus, when forming finishing coating 1.5 mm thick per 3-5 sq. m. of the surface, one package will be enough.

If such wallpaper is applied to the wall with a sprayer, then their consumption per unit area will be almost two times less. In this case, the working mass is loaded into a container, from which it is supplied under pressure by means of a compressor to the nozzle of a special guide gun. This method allows the coating to be applied more evenly and in a thinner layer, which, accordingly, affects the amount of mixture consumed. With the skillful use of this device, one package of the mixture can cover 7 squares of wall space, which means that only about 150 g of dry mixture is consumed per 1 meter. But it is important to consider that only short-fiber liquid wallpaper is used for spraying.

Knowing the total area that needs to be covered with a finishing material, and its consumption per unit surface, it will not be difficult to theoretically calculate how many packages are needed for repairs. But in practice, it's not so simple. There are a number of factors that can affect the amount of material consumed during its application. If they are not taken into account, then the wallpaper will most likely have to be bought in addition.

Even if you are sure that you calculated correctly required amount material, it is better to purchase a mixture with a small margin, as it may come in handy in unforeseen circumstances or when possible repair coverage in the future.

What can cause more wallpaper material to be consumed than expected?

There are several objective reasons leading to overspending of wallpaper.

1. Insufficiently thorough mixing of the mixture during its preparation, which leads to the formation of lumps, due to which the surface area covered is reduced.
2. Irregularities in the base surface, requiring a thicker layer of the mixture in some places.
3. Failure to comply with the instructions regarding the proportions when mixing wallpaper, when they are made too liquid, because of which they slide off the wall, so it is impossible to achieve a thin layer.
4. Inept movements with a spatula, which must have a certain angle of inclination when applying the finishing material to the wall.
5. Too smooth base surface, which does not allow you to fix the wallpaper and control their thickness.

In order to ensure sufficient adhesion of the facing mixture to the wall, it is better to pre-coat the surface to be finished with a primer containing quartz.

Although a sign of professionalism is the ability to apply facing material thin layer, sometimes the customer repair work may insist on increasing the thickness of the coating. And this makes some sense. The fact is that liquid wallpaper is a good sound insulation, and the thicker their layer, the less sound permeability of the wall. Of course, such a decision will lead to the fact that the consumption of the mixture will increase and, accordingly, the cost of repairs will increase. But for those who are financially secure, this is not a problem.

Whatever your economic opportunities, worrying about the quality of the work done is in any case useful. Therefore, the above information may be timely if you are starting a repair. Even before purchasing liquid wallpaper, you will know their approximate consumption per unit surface area. And given the factors that increase the consumption of material, you will try to strictly adhere to the instructions when performing work or hire a qualified specialist to carry them out.

So that the expenses are not too large, you need to correctly calculate the amount of liquid wallpaper per square meter required to complete finishing works. Even if there are a few extra ones, then they are easy to use to replace the damaged area. But still, maximum accuracy does not hurt.

We calculate the volume

The main feature of the calculation of liquid wallpaper will not be the number of rolls, but 1 kg of dry mix per 1 sq. meter of wall or how many packs are required for the same area. Decide on necessary volume liquid wallpaper for 1 m 2 is easy. Calculations are available even to a person who does not have special skills, vocational education. The work is facilitated more if drawing is not planned and there is a calculator at hand.

Why is the volume of liquid wallpaper per square. meter must be determined in advance:

• because of the ability to calculate the exact consumption of one package for a certain section of the wall;
• it will be known in advance how much the total cost of repairs will be;
• easier acquisition and production of liquid wallpaper with a margin.

And it also excludes the possibility that they will end in the midst of the repair process. You also need to understand that each manufacturer has its own calculations of material consumption per 1 sq. meter. Below we offer you to get acquainted with the calculation of wallpaper from the company Prestige:

Consumption of one package

There are several factors that have a serious impact on the final consumption of 1 kg of liquid wallpaper per 1 sq. meter. Let's consider them in more detail, because from each additional element depends on how many packs of the mixture you need to buy in order to apply wallpaper in one go.

• Are there cracks in the walls? They increase the required volume;
• how long does the material keep? Liquid wallpaper becomes less elastic if it is kept mixed longer. three days, but at the same time, if you freeze ready-made, then they can be stored for up to three months without loss of quality;
• amount of water. The wallpaper slides off if it is more than the prescribed norm - excess liquid will flow down the walls, the lower layers will get wet and it is likely that they will move away. In addition, the drying time increases several times;
• How thoroughly is everything mixed? If mixing is insufficient, clots appear. Because of them, the consumption per square meter increases, and the quality of the coating itself also suffers. The heterogeneity of the cooked mass will affect the quality of the interior.

The consumption of one package per 1 sq. m depends on how professionally the application is performed. And how much home master aware of the right technologies. Under normal conditions, without additional obstacles, one package should be enough for 4 square meters if the application is carried out manually.

It is recommended to use modern instruments for application like sprayers. They will make a consumption of 1 kg per sq. meter more economical. Thanks to the use of this device, it is easier to control the thickness of the layer, and the surface of the walls is covered evenly.

For a faster calculation of the consumption of liquid wallpaper, we suggest using the table of room areas standard sizes. Here are the most common options:

The temperature and humidity of the air determine the time during which the liquid wallpaper dries completely. This process usually takes 2-3 days. Dark wet wallpaper becomes lighter as it dries. It doesn't matter how much composition is used.

It is not necessary to prepare the surface, but carrying out such work will help to save a lot on the purchase of finishing materials. It is recommended to putty the entire wall. Then working surface will be the same in all areas.

The primer will add strength to the surface and protect against moisture penetration.

Advice! If the wall is initially dark, its color can be seen even after the wallpaper has dried. Before applying liquid wallpaper, it is better to paint such surfaces white. For this, water-based paints are used.

For economical consumption, it is recommended to adhere to a layer thickness of 2-3 millimeters. This is if the packages do not indicate other, more optimal parameters that the wallpaper has. The indicators should not be exceeded, otherwise the coating will not be strong enough. The thicker the layer of wallpaper - the harder it is to work with it. Drying time is increased.

The high cost of liquid wallpaper from leading manufacturers does not always become a symbol best quality. Sometimes it is the same for those materials that are cheaper or made independently. The overpayment appears only at the expense of the brand. The average one will be the least hit on the budget, and the quality will remain at an acceptable level. The photo shows good example how to calculate sq. meters of area for applying liquid wallpaper:

Premises with a complex configuration are usually divided into several sectors. The total area is easier to calculate if you multiply all the parameters of the height, width and length of the room. This rule applies to different niches with other elements. For example, refers to columns. Simply multiplying the length with the width will help in determining the area of ​​the ceiling. But for him it is better to take more of the mixture, since this surface causes the most problems and, accordingly, consumption. For the ceiling, you need to remember that when self-manufacturing liquid wallpaper, add a little more adhesive to the batch.

How to make liquid wallpaper yourself and correctly calculate the consumption per square meter. meter will help the following video:

Preparing for repairs involves drawing up a cost estimate for basic materials, it is easier to keep records and plan work. I don’t really want to be left with a surplus, or run headlong in search of the right brand or wallpaper color. The cost of liquid wallpaper is probably one of the most difficult to predict indicators, too much needs to be taken into account and foreseen.

How to take into account all the costs of liquid wallpaper

In repair, there are many situations associated with the use of bulk or liquid materials. And for almost all of them there is a certain calculation method. The exception is decorative plaster and related liquid wallpaper. Why is it difficult to calculate the consumption of the mixture per 1 sq. meter? Too thin a layer of material is applied to the wall, its thickness can fluctuate on each square meter of the wall by 40-50%, depending on the degree of preparation of the walls for coating.

• The density of the wallpaper solution, as far as the prepared consistency corresponds to the optimal consumption per square meter;
• The method of applying the wallpaper mixture to the surface of the walls, for foam roller with a spatula consumption rate per square meter. will be higher than if you use a pneumatic sprayer;
• The complexity of the geometry of the walls. On a curved and unprepared surface, the consumption of liquid wallpaper can increase catastrophically, even in a small area of ​​one or two meters. square flow wallpaper mixture may exceed the amount of material used for the entire wall;
• Experience and practical skill in applying a certain type of liquid wallpaper.

For your information! Often, the consumption of a liquid decor solution is one of the indicators of the skill level of an upholsterer, therefore, if you decide to apply liquid wallpaper yourself, the material consumption per square meter under equal conditions will be at least 20-30% higher.

In this case, it would be more correct if the wallpaper is applied with a pneumatic sprayer of a liquid solution. This method gives a more uniform distribution of the liquid wallpaper solution on each meter of the wall, reduces physical stress and increases productivity. One meter sq. walls are sprayed three times faster than if wallpaper is applied with a roller, and for the ceiling, wallpaper is applied an order of magnitude faster. Within two to three hours, using a sprayer, you can easily process the surface of the walls of one living room of 40 square meters. with less physical activity.

The disadvantages of working with a sprayer include the need for its constant adjustment and quality control of spraying the solution with a nozzle. In addition, the spray itself during operation must be periodically cleaned and maintained, and the wallpaper in the tank must be changed.

For example, one package of dry cotton liquid wallpaper, weighing 1 kg, is enough for spraying 6-7 square meters. meters. If you work with a spatula and a roller, the same amount of solution is enough for a maximum of 4-5 square meters. Unfortunately, the mechanized method of applying wallpaper solution is difficult to use on walls with large quantity defects, or on transitional zones window - corner - doorway. In such cases, the consumption of the wallpaper mass increases to the level of the manual method of applying the material, and if it is necessary to repair defects on the wall, a spatula is indispensable.

Method for determining the consumption of liquid wallpaper

There are two main ways to calculate the consumption of a liquid wallpaper solution: according to the standards of the wallpaper manufacturer and the practical measurement of the rate of material consumed per square meter. meter of concrete walls. In the first case, it is possible to roughly estimate the costs of a particular brand of liquid wallpaper and calculate the cost of materials for performing work on applying liquid wallpaper, in the second case, it is possible to accurately calculate the required number of packages per 1 kg of dry mix, based on the square footage of the walls of the rooms.

Theoretical way to determine the need for a material

Most firms producing or selling different kind building materials, offer to calculate the required number of packages of dry mix, using the help of an online calculator. To do this, just enter the measurement data of the room and the brand of liquid wallpaper into the calculator. The program itself will issue data on how many packs of liquid wallpaper are needed, based on its data on the mixture consumption of a specific type of wall and application method. This is convenient, but it is known from practice that the accuracy of the calculation can fluctuate greatly, so buyers often play it safe by increasing the volume of purchased packages by at least 10%, which, in fact, is what sellers of building materials and owners of online calculators need.

You can more accurately calculate how much material is needed if you use data on consumption per square meter. meter of the wall indicated on the packaging of liquid wallpaper. As a rule, firms provide averaged information on the consumption of liquid wallpaper per 1m 2 or, based on the area covered with a solution of 1 kg of the mixture, summarized in tabular form. Knowing the square of the walls and the weight of one package, you can easily calculate the costs and the estimated amount of wallpaper mixture.

A practical way to determine the consumption of liquid wallpaper

Theoretical data on the estimated consumption rate are not always reliable and suitable for practical work, rather, they help to assess the level of costs for repair and application of wallpaper paste. Actual material needs may differ, so for expensive brands decorative coating always carry out a control batch and a trial application of wallpaper paste on the surface.

The easiest way to do this is in a separate room, where the quality and texture of the plaster corresponds to the surface on which the decor is supposed to be applied:

1. On the free surface, a strip 70-100 cm wide is marked, from ceiling to floor, we divide it into three parts;
2. We prepare a test solution for 200-300g of dry mix and weigh it on a scale with a weighing limit of 1kg;
3. With a roller and spatula, we close up with liquid plaster the third part of the marked surface with an arbitrary, most convenient way. At the same time, we rub the mixture with a spatula;
4. We calculate the amount of mixture used. To do this, we measure the area with the applied plaster and determine the loss based on the results of re-weighing the container. If the received consumption exceeds the average rate indicated on the package, it is necessary to analyze the situation and deal with the reasons for the overspending;
5. We carry out repeated application of the mixture on the remaining marked surface of the test area, trying to minimize the consumption of the solution and maintain the required quality of the layer. Once again we determine the average loss of the wallpaper mass, and if the value differs from the norm by no more than 10%, we will assume that we have chosen the application technique correctly.

The operation of the pneumatic sprayer is regulated in a similar way. But, unlike the previous method, the main problem of adjusting the exact flow rate is correct selection solution consistency and operating air pressure in the sprinkler system.

2. Consumption of one package *, i.e. how many sq.m. 1 pack of each type of decorative plaster is enough.

How to use a calculator to calculate how much liquid (silk) wallpaper costs:

Enter the parameters of the room for which you want to calculate the price:

1. The length of the room in meters;
2. The height of the room in meters;
3. The width of the room in meters;
4. Number of doors and windows (pcs).

Next, click the "Calculate" button - that's it! The calculator will display in front of each type of liquid wallpaper the number of packages that you need to apply to the walls of the room and their final price and you can make a purchase decision.

* Please note that the consumption of liquid wallpaper is calculated based on the recommended thickness of the application layer of 0.8 - 2 mm, depending on the type of material, respectively, if the thickness of the application layer changes, the consumption will increase proportionally. Also, material consumption may increase if the surface has irregularities and cracks. Our material will easily disguise them, but at the same time, the consumption increases, because. part of the material clogs irregularities. Please note that as the application layer is increased, the shade of the resulting surface may become darker.

Among the huge variety of decorative finishing materials, liquid wallpapers occupy a leading position due to their affordable price, ease of application and high performance.

When purchasing liquid wallpaper, the consumption of the mixture per 1 sq. m. can be found in the table placed on the product packaging.

Repair and decoration of the wall requires determining the exact amount of materials needed.

Liquid wallpaper is textured Decoration Materials for ceilings and walls, reminiscent of decorative plaster. From roll paper wallpaper they are distinguished by the technology of application, the absence of seams and the possibility of decorating any curved surfaces.

Compositions are made from silk, cotton or cellulose fibers and dry KMS glue. To improve the aesthetic and operational properties, plasticizers, dyes, mineral chips, colored balls, sparkles or mother-of-pearl can be added to the mixture. Supplied dry in sealed bags.
Each package has instructions for preparing and applying the mixture, where you can see how much material is needed to decorate one square of the surface.

The solution is prepared by adding to the dry composition warm water and thorough mixing by hand. After swelling of the mass within 8-10 hours, you can start finishing work.

The finished solution is applied to the wall with a trowel or spatula. The mixture is spread over the surface with a plastic grater.
With a special roller, you can create relief patterns and ornaments.

Liquid wallpaper can also be applied mechanically, using a spray gun. This method will allow you to create a more uniform and thin layer, and significantly reduce the time of work.

Compared with decorative plaster, applying liquid wallpaper is much easier and simpler.

The finish is environmentally friendly, safe and highly vapor permeable. All these factors provide a comfortable and healthy indoor climate, which allows them to be used for decorating children's rooms, bedrooms and living rooms.

Cultivated Area Calculation

The normative consumption of the material is usually indicated on the packaging.

1. We determine the area of ​​\u200b\u200ball the walls by multiplying the perimeter of the room by the distance from the floor to the ceiling.
2. We calculate the area of ​​​​windows and doors by multiplying their width by height.
3. From the area of ​​the walls we subtract the area of ​​doors and windows, we get the area of ​​the walls to be finished.
4. The ceiling area is determined by multiplying the width and length of the room.
5. Adding the area of ​​all walls minus windows and doors and the area of ​​the ceiling, we get the total area of ​​the treated surfaces.
6. Multiplying the obtained indicator by the normative consumption of the mixture, we obtain the exact consumption of material required for the entire scope of work.

We divide premises of complex configuration into separate sectors, determine the areas of individual parts and sum them up.

With the correct calculation, one kilogram of dry matter should be enough for 4-5 square meters manual application layer up to 2.5 mm. With mechanized application, a kilogram is enough for 6-7 squares of a wall.

Buy 10-15% more dry mix than you need for calculation so that you have a reserve in case of correcting application errors, damage to decorative coatings or other unforeseen situations.

What affects material consumption

Consumption directly depends on the skill of the finisher. At proper preparation composition and professional application, it will be minimal.

Quantity calculation decorative material must be done in advance in order to know the total cost of repairs and purchase the exact amount of liquid wallpaper. Consumption rates per 1 m2 of coating average 200-300 grams of dry mix. The consumption table on the packaging of materials does not always correspond to the actual figures.

When buying liquid wallpaper, it must be borne in mind that the consumption of one package depends on various factors:

• too smooth surface makes it difficult to apply and control the thickness of the layer, embossed - will require the application of a thicker layer in certain areas;
• dark walls can show through the decorative coating and cause an increase in the layer;
• the use of a composition that has been stored diluted for a long time, as well as a violation of the preparation technology, will affect the layer thickness and lead to an overrun of the material;
• the presence of potholes and cracks on the base for finishing entails an excess standard flow mixtures.

A properly prepared surface contributes to a significant reduction in the consumption of decorative composition due to the possibility of applying a minimally thin layer.

How to reduce consumption

There are various ways to reduce the consumption of liquid wallpaper when decorating walls and ceilings:

• when applying liquid wallpaper with a spray gun, you can achieve minimum thickness, no more than 1 mm;
• careful leveling of the base and applying a primer layer under liquid wallpaper will reduce material consumption by reducing the thickness of the coating;
• putty perfect white color exclude translucence of thin layers of finish;
• thorough mixing of the material will avoid the formation of lumps and clumps of cellulose fibers and reduce the thickness of the decorative layer;
• using the dissolved residues of the previous coating in the work, you can save on the purchase of new material.

An important point in saving the decorative composition is the experience and skill of application. Performing work for the first time, it is unlikely that it will be possible to maintain a uniform thickness of coatings.

Control batch

The actual consumption of liquid wallpaper per 1 square meter may differ significantly from that indicated by the manufacturer on the packaging.
This difference is not particularly important when cheap, budget material from cellulose or cotton fibers.

When using expensive materials from artificial or natural silk, the cost of each package matters.

Before buying a dry mix, it is worth making a control batch and applying the solution to small plot walls, which can later be hidden by furniture.
This will make it clear how many squares a package of decorative coating will last in order to calculate the required amount of liquid wallpaper and purchase them if necessary.

How to use leftover material

Store diluted liquid wallpaper is allowed no more than 2-3 days in a cool place.

If you have prepared more liquid working solution than necessary, dry the rest of the unused material by spreading it in a thin layer on polyethylene film. After drying, the mixture must be thoroughly fluffed, folded into a plastic bag, releasing air from it and tightly tied. Wallpaper different colors and textures need to be stored in separate packages.

The dried composition is suitable for long-term storage in a dry, dark place, and for work you only need to dilute it with water.

Liquid decorative wallpaper - unique material allowing families with small children and pet owners to use it.

Due to the stock of unused composition, any damage to decorative coatings can be quickly and easily repaired.
