Wallpaper glue consumption- a very interesting topic. The fact is that many (now almost all) manufacturers write on their packaging: “for 7 rolls,” “for 15 rolls,” or even “for 30 rolls.”

In fact, this is nothing more than a formal inscription that means almost nothing, is a marketing ploy and is supported only by the fact that de jure it is not prohibited by the Consumer Rights Law. Therefore, under no circumstances and never should you be guided by this inscription when purchasing wallpaper glue.

What does the inscription indicate, for example, “for 7 rolls”? And she points out that in the presence of perfectly smooth walls with an ideal absorption coefficient, this package of glue is designed for sticking (on an ideally prepared surface) an amount identical to that contained in seven rolls of 10.05 meters.

“Ideal” values ​​exist only in the tests to which the specified products are subjected before release into series. In real rooms and apartments everything is different. Therefore, the amount of wallpaper glue and its actual consumption differ significantly from what is written on the front of the package.

What then is this expense? Maybe there are some that could help us calculate the real amount of glue needed for the job?

I’ll say right away that there are no “magic” methods or formulas - everything is much simpler. Wallpaper glue, as you know, is not sold by weight, but is packaged in standard packs weighing 250 grams (there are also packs of other weights).

So, the calculation of the glue required for wallpapering walls is done as follows: on average, one pack is enough for 20 - 25 square meters of the surface of non-ideal (that is, the most ordinary) walls. The value changes upward due to the following factors:

a) (do not forget to do the necessary work before wallpapering, and certainly);
b) very uneven walls (the more various differences there are on the surface, the more glue “gets stuck” in them, and therefore its consumption increases;
c) pasting with light wallpaper (light wallpaper absorbs more glue than heavy wallpaper);

Based on this, for a room with an area of ​​12 - 15 square meters with ceilings 2.50 - 2.60 meters high, about 350 - 400 grams of dry glue, or approximately 1.5 packs, are required. For a room of 17 square meters. meters, you will need two packs, and pasting the walls in a 7-meter kitchen can cost you just one pack.

Interestingly, glue consumption does not depend much on: paper, non-woven or vinyl wallpaper of the same width and thickness “takes” on average almost the same amount of it.

This calculation may seem somewhat abstract to some, but I usually use it because it simple, fast and effective. In finishing work carried out in the old building, practice plays a much more significant role than theory. Some (very small) role is played by the ones you use: brushes, rollers, etc.

That is why all calculations should be based on data obtained using your own experiments, while not forgetting that additional calculations may be required at any time.

Here's a simple way to calculate it. However, if you are going to cover a large area with the same wallpaper (for example, 250 square meters or 500), then the wisest decision would be to first purchase several packs of glue and use them to cover part of the surface, estimate glue consumption and purchase the required quantity.

The fact is that with small areas one or two extra packs do not play a special role, but on large orders the overrun can be quite sensitive. Therefore, you need to think before you buy. As, indeed, in any other case =)

When making repairs - and, in particular, when gluing wallpaper - it is necessary to accurately calculate the consumption of various materials that are used. With wallpaper, everything is quite simple, because their consumption approximately corresponds to the area of ​​the walls, you only need to make a small error for various potential errors, and also, if there are overlapping places or holes in the wallpaper, then on them.

The amount of glue directly depends on the method of applying it to the wallpaper.

Everything is much more complicated with glue. Its consumption depends on many factors. We can identify a number of key ones, which will be discussed further.

Wallpaper type

As you know, wallpaper has several varieties, on which their characteristics depend. One of the characteristics on which glue consumption depends is the thickness of the wallpaper, which must be taken into account.

• If we take paper ones, the thinnest ones, then they require the least gram of glue per m2. Moreover, any glue is suitable for them.
• If a person chooses vinyl, jute, wallpaper with fiberglass, and so on, then not only does the overall consumption increase, but there is also a need to select special types of glue. Moreover, it is often necessary to select not just a strong glue, but also a special type, for example, glue with a fungicide for waterproof wallpaper.

The need for priming

Sometimes the surface is not one hundred percent ready to hang wallpaper on. In this case, it is necessary to pre-treat the surface. And this will also directly affect the overall glue consumption.

If we take approximate figures, then during preliminary priming, 5-10 extra grams of glue must be added to each m2.

Surface type

Consumption also directly depends on what kind of material the gluing is carried out on. For example, if it is wood or fiberboard, then the consumption will be minimal. The reason is that the glue penetrates very quickly into the top layers and sticks very quickly. With other materials everything is somewhat more complicated.

Wallpaper sticks easily to a flat surface

For example, concrete, stone or plaster do not have the same properties, so they require slightly more glue. Therefore, when working with such surfaces, feel free to add 5-10% to the amount calculated in advance.

Average consumption

To roughly understand what exactly the consumption of this or that glue will be, you need to pay attention to the turnover of its pack. Usually it indicates the approximate amount of glue required for gluing wallpaper of one type or another. It is difficult to give universal figures, because each brand of adhesive composition has its own distinct characteristics.

Information on the back of the wallpaper paste pack

If we still take some average indicators, then for thin paper wallpaper it is usually 15 grams per m2. If you take thicker wallpaper, for example, vinyl, then this figure can reach up to 50 grams per m2.

That is, you can roughly estimate that the average consumption will be something like 20-30 grams per m2.

But, again, you still need to study the information on the pack as carefully as possible in order to take into account the characteristics of different types of glue and different wallpapers.

Counting principle

When you know approximately how much glue is needed for each m2, you need to start calculating. They are carried out quite simply. It is necessary to measure the length of the walls and the height of the ceilings for each room. Based on this, you can calculate the area of ​​each wall.

Next, you need to subtract from this area those areas that will not be used in any way, for example, windows or doors; their area is also very easy to measure. After this, it is worth making adjustments to the surface - whether a preliminary primer is needed, or in this case it is realistic to do without it, as well as its type.

Priming walls with wallpaper glue before gluing

Next, using the instructions on the back of the package, you need to calculate the approximate glue consumption in this case, based on the type of wallpaper you have. If for some unknown reason it turns out that you have glue without the original packaging, then you can take the approximate values ​​that were given just above.

After this, you simply need to multiply the data from the packaging by the total area of ​​wallpaper in each room. You can take a little more glue so that in the future, if you need to re-glue any part, there will be a reserve. As a result, you will come up with a number, usually several kilograms, which will indicate exactly how much glue you will need. If you suddenly need to paste over the ceiling as well, it must also be taken into account.

Bright wallpaper on the ceiling

Remember that buying a little more glue will be a smart decision, but it’s not worth buying it for future use, because each glue has its own expiration date, and gluing is already dangerous, and besides, it will no longer be as effective. It turns out that you will simply waste the extra money without winning anything.

Which glue is more economical

If you want to choose glue that will be used most economically, then you should give preference to liquid variations. Their quality will be the highest, they will not have lumps or other imperfections. But there is a catch, which is that these adhesives are more expensive than others. So, in an effort to save money, you may, on the contrary, spend more money.

Material consumption rates can be used by all parties, regardless of the form of ownership and departmental subordination, to determine the need for resources when performing construction and installation work, to calculate the planned and actual cost of these works based on the calculation of production costs in prices and tariffs for the period for which the estimated and actual cost of work.

TECHNICAL PART

1. General part

1.1. This collection includes construction processes for wallpaper production.

The collection was developed on the basis of collection No. 15 “Finishing works” SNiR-91 (SNiP 4.02-91, SNiP 4.05-91) with specification of the structure of construction and installation processes and highlighting operations involving the consumption of materials.

1.2. Standard indicators of material consumption are intended to determine the resource requirements when performing wallpaper work and to calculate the planned and actual costs of these works based on the calculation of production costs in prices and tariffs for the period for which the estimated and actual costs of the work are determined. Standard indicators are applied by all participants in the investment process, regardless of their form of ownership and departmental affiliation.

1.3. The normative indicators are based on production standards for the consumption of materials, which determine the maximum permissible consumption of materials for the production of a unit of product of a construction process (work operation) of a given quality at a given level of equipment, technology, construction organization and use of material resources that meet the requirements of standards and regulatory documents.

1.4. The standards take into account the net consumption and difficult to eliminate losses (waste) of materials generated within the construction site when performing work operations provided for by the technology and organization of production.

1.5. The standards do not include:

Losses and waste of materials caused by deviations from regulated technological processes and operating modes, violation of established rules for the organization, production and acceptance of work, and the use of low-quality materials;

Losses and waste of materials generated during their transportation from the supplier to the on-site warehouse of the construction site;

Consumption of materials for repair and maintenance and production and maintenance needs in terms of manufacturing, repair and operation of equipment, fixtures, stands, mechanization equipment, etc.

1.6. The standards in this collection show the consumption of materials without gluing the curb.

When performing this operation, per 100 m2 of surface to be pasted, the following should be added:

dry CMC glue - 0.012 kg for simple and medium-density wallpaper and 0.018 kg for thick wallpaper, border - 44 m.

1.7. When gluing the surface of the walls with washable wallpaper on a paper basis, the consumption of wallpaper is given when gluing it overlapping, and when gluing it on a fabric basis - end-to-end.

1.8. When gluing the surface of walls with self-adhesive film PDSO-12 to prepare 1 ton of primer composition, you should use:

polyvinyl acetate glue - 340 kg,

white spirit - 660 kg.

2. Rules for calculating the volume of work

2.1. The scope of work on wallpapering walls should be calculated based on the area of ​​the surface to be pasted.

2.2. The area of ​​window and door openings is excluded along the outer contour of the frames.

2.3. The scope of work on door upholstery should be determined based on the surface actually being upholstered.

The calculator will help you calculate how much glue is needed for 1 m2 of wallpaper. You enter basic data into the service (surface area, glue consumption kg/m2, package packaging) and immediately get the result. Be sure to include a construction reserve of at least 10% in your calculations so that you do not have to purchase additional material during the work process.

The consumption of wallpaper glue per 1 m2 is usually indicated on the packaging of the purchased composition, but practice shows that this consumption is not always accurate and during work, as a rule, the glue runs out at the most inopportune moment.

It is also not uncommon for cases when, after wallpapering the areas planned for renovation, a large amount of unclaimed adhesive remains, which has to be thrown away.

Dependence of glue consumption on the materials used

To calculate the glue required for wallpapering a room, you must first of all decide on the type of wallpaper that will be used during work, select the glue and determine the area that needs to be covered with wallpaper. To do this, the following factors must be taken into account:

1. It is necessary to carefully prepare the surface on which you plan to apply wallpaper.
2. A wall covered with plaster must be thoroughly puttied and coated with a primer, since without these operations there will not be enough glue, since it will be absorbed into the porous base. The plaster consumption calculator will help you quickly calculate the required amount of material for a given type of construction work.
3. It is necessary to take into account the type of wallpaper, since the glue consumption for them may be different. So, for example, for paper wallpaper, when working with which the glue is applied to the material itself, the consumption will be the same, but for wallpaper on a non-woven basis, when the glue is applied to the base to which the wallpaper is glued, the consumption will be completely different.
4. When determining the area of ​​the surface to be pasted, you must not forget to subtract from it the areas of window and door openings.

For each type of wallpaper you need to use a special glue

The ability to absorb glue from different materials and the unequal drying speed of the glue contribute to a wide variation in the consumption rates of the adhesive composition, the calculation of which is still advisable to carry out based on practical experience, and not on the descriptions on the packaging.

The most profitable option for wallpapering in terms of economical glue consumption is to work on a flat and smooth base.

Calculation of wallpaper adhesive consumption

After studying the initial data on the technical characteristics and qualities of the materials used in the process of pasting and the walls themselves, you can proceed directly to the calculation itself. To do this, you must follow the following instructions:

• First, the area of ​​the walls of the room is calculated. For example, the length of a room is 6 m, width 3 m and height 2.5 m. We calculate the area of ​​the long wall 6 x 2.5 = 15 m2, then determine the area of ​​the short wall 3 x 2.5 = 7.5 m2. We add the results obtained and multiply them by two: (15 + 7.5) x 2 = 45 m2. The area of ​​doors and windows is subtracted from this value. For example, the window area is 1.2 x 1.5 = 1.8 m2 and the door area is 2.1 x 1.1 = 2.31 m2, 45-(1.8 + 2.31) = 40.89 m2. We get an area of ​​approximately 41 m2;
• we determine the amount of wallpaper required for gluing on walls with a total area of ​​41 m2, with a wallpaper width, for example, equal to 0.53 m and a length equal to 10.5 m. 41/(0.53 x10.5) = 7.37 rolls ;
• Next, using the instructions on the packaging, we determine the volume of glue required to stick a given amount of wallpaper. For example, a package of glue weighing 200 grams is usually written that this is enough to stick 6-9 rolls;
• Accordingly, in this case, one package of glue will be enough to wallpaper a room.

When calculating how much glue is needed for non-woven and vinyl wallpaper, you need to take into account their actual width. When diluting the dry adhesive composition with water, you must follow the instructions indicated on the packaging. For more information on how to properly prepare wallpaper glue, watch this video:

Even an open pack of wallpaper adhesive cannot be stored for a long time, so it is necessary to make the most accurate calculations of the adhesive.

In any case, before purchasing glue, you should agree with the store about the possibility of returning unused adhesive composition after use.

Dependence of glue consumption on its brand and type of wallpaper

Today on the construction market there is a great variety of adhesive compositions designed for a wide variety of wallpaper types, taking into account the surfaces on which these wallpapers can be glued.

The glue consumption, depending on its name, types of wallpaper and dilution methods, can also be determined from the table:

5-7 rolls
25-35 m2 7.5 liters

For gluing paper wallpaper, ordinary wallpaper glue is used, in which starch or its substitute methylcellulose is used as a base. All other wallpapers are glued with specialized glue, the consumption of which is determined separately for each specific case. To learn how to choose glue, watch this video:

Vinyl, non-woven and fabric wallpapers are glued with glue, which should contain a high content of PVC and PVA emulsions, up to 50%. The same glue is used for gluing glass wallpaper.

You will also need specialized glue to apply wallpaper in rooms with low temperatures, high humidity, drafts and other possibly difficult conditions. The glue consumption for this wallpaper per 1 m2 is also determined individually.

In most cases, the packaging of wallpaper glue indicates its consumption per square meter. However, in reality, there is almost always excess glue left or not enough and you have to run to the store for new packaging. What this is connected with and how to correctly calculate the consumption rate of wallpaper glue per 1 m2, we will talk in this article.

Let's start with the fact that a plastered wall absorbs glue well, and if you do not apply a primer to it first, you will have to use more glue than the amount indicated on the package, approximately +5-10 g per square meter.

The second point on which the consumption of wallpaper glue will depend is the area to be covered. When completely covering walls with wallpaper, calculations must be based on the entire area of ​​the walls. If you plan not to touch the space behind the furniture or implement other design ideas, not the entire surface of the walls will be covered with wallpaper, and accordingly, you will need less glue. In this case, from the total area of ​​the walls it is necessary to subtract the area of ​​those areas that will not be covered with wallpaper.

The third point that you should pay attention to when calculating the consumption rate of wallpaper glue is the type of wallpaper. In some cases (paper wallpaper), the glue is applied to the wallpaper itself, in others (non-woven, vinyl) - to the wall. Different absorbent properties of surfaces and drying speeds cause different glue consumption.

Finally, in order to achieve the best result, you need to use a different adhesive for each type of wallpaper. This information is always indicated on the packaging.

How much wallpaper glue do you need?

Take into account the above data when starting to calculate the consumption of wallpaper glue per m 2.

We will provide a formula for calculating average consumption, which you, of course, can use in your own calculations, taking into account the nuances of your apartment or house.

1. Calculate the area 2 perpendicular walls in a rectangular room, and then multiply the resulting figure by 2. To calculate the area of ​​a long wall, multiply its height by its length. For example, 2.8 m * 4 m = 11.2 m 2. Similarly, we calculate the area of ​​the short wall: 2.8 m * 3 m = 8.4 m 2. Next, we calculate the total area of ​​the walls in the room: (11.2 m2 * 2) + (8.4 m2 * 2) = 22.4 m2 + 16.8 m2 = 39.2 m2.

In such calculations, specialists subtract door and window openings from the total area. However, if you do not consider yourself a professional in this matter, we recommend not to experiment. The remainder of the wallpaper may be needed, for example, to cover the wall behind the radiator or to replace scraps that were lost when combining the pattern, and the glue will be useful for gluing the joints.

2. Calculate the number of rolls of wallpaper. For example, let's take paper ones. Their standard width is 0.53 m. Usually the roll length is about 10.5 m. We calculate the number of rolls as follows:

39.2 m2: (10.5 m* 0.53 m) = 7 rolls.

3. Next, we calculate the consumption of wallpaper glue, for example, Moment Classic 200 g. The consumption on the glue packaging is 6/9 rolls. We conclude that to paste a room with an area of ​​39.2 m2 you will need 1 package of glue. When diluting, follow the proportions of water and adhesive indicated on the package.

For non-woven and vinyl wallpaper, the calculation is performed in a similar way, taking into account the larger width of the roll.
