Consumption of materials per 1m2 of a wall made of hl. Calculation of drywall partitions (gypsum plasterboard): calculator. The design of the suspended ceiling structure made of plasterboard

Hi all! It's no secret that I love doing DIY repairs and sharing my experience. Today I want to tell you about an unpleasant story that happened to me and my friend. We decided to make repairs with friends, but incorrectly determined the consumption of self-tapping screws needed per square meter. m. GKL. And since we were putting the country house in order, we had to stop work and go to a local store. I will not talk about overpayments, but the loss of time was noticeable. To avoid such a prospect, study the calculation rules and purchase the right amount of self-tapping screws!

Everyone who has decided to make repairs using a drywall sheet is wondering how many self-tapping screws will need to be prepared for 1m2 of a drywall panel. As a rule, there is no unequivocal answer to this question, since their number is calculated depending on the step of attaching drywall to metal or wooden profiles.

Basic rules for calculating the consumption of self-tapping screws

Most often, drywall is attached to the profile with self-tapping screws, while maintaining a step of 30 cm. If you need to increase the strength of the structure, the step is reduced to 10 cm.

Important! Self-tapping screws should never be fastened closer than 10 mm from the edge to avoid cracking.

Thus, it turns out that you can only find out the approximate consumption of self-tapping screws. To calculate how many self-tapping screws you need, you need to consider several parameters:

GKL size: it is available in standard sizes - 1200x2500 mm. In addition, there are non-standard panels, the size of which is 600x2000 mm. To make a calculation of the approximate number of screws, you need to take the first option, since it is more common.

1. Attachment step. Experts recommend fixing the GKL in increments of 35 cm, as this indicator is able to ensure the durability and reliability of the finished structure.
2. The number of layers of drywall. If it was decided to install drywall in several layers at once, self-tapping screws must be fastened with different steps. For example, the first layer will be attached every 60 cm, and the second - every 35 cm.

Having decided on the mandatory indicators, you can correctly calculate the required number of self-tapping screws in order to attach the GKL. It will take about 70 pieces per sheet, and at least 110 pieces per two layers. By choosing a specific fastening step and the number of panels for the manufacture of a future structure, you can easily calculate the consumption of fasteners.

Types of self-tapping screws for drywall and more: calculate the consumption

Fasteners for drywall have different sizes, types and features of the coating. These include self-tapping screws for metal, wood, dowel-nails, butterfly dowels and many others. Most often, for both wooden and metal profiles, self-tapping screws are used.

The type of material determines the consumption

Consumption of self-tapping screws for fastening the profile

When forming a frame from a metal profile, special metal screws are used. Their dimensions are: length 9.5 and 11 mm, diameter 3.5 and 9.5 mm. They are available with two types of protective coating, namely phosphate and zinc. Their head has a hemispherical or semi-cylindrical shape. It is supplied with a Philips No. 2 slot, designed for a cross-shaped bit nozzle.

The base of the heads on the side of the thread is provided with notches. This allows you to protect the fastener from possible self-loosening. The thread pitch of such self-tapping screws is very frequent, which is what distinguishes them from other representatives of fasteners designed for fixing drywall. Such fasteners are also called self-tapping bugs. It is one of the most popular fasteners on the modern construction market.

There are several types of such products:

1. Self-tapping bugs with a drill are used to fasten a profile with a thickness of up to 2 mm. With their help, fastening is carried out without any serious problems. The most important thing is to adjust the twisting force of the screwdriver. This is required to prevent thread stripping in the profile. For best results, it is recommended to use a high-quality bit that perfectly aligns its own axis with the axis of the screw. In addition, it firmly holds the fastener when the profile is twisted, without deforming the slot of the fastener. For each type of self-tapping screw used for fastening both for metal and for wooden profiles, the documentation from the manufacturers contains information that refers to the recommended tightening forces.
2. Self-tapping bugs with a sharp end provide the ability to drill holes in metal sheets with a thickness of up to 1.2 mm. When using such elements, the profile material is not destroyed, which contributes to the preservation of its structure. Recommendations for choosing the appropriate tool and nozzle selection are the same as in the first case.

In order to better fix the GKL, in some cases an additional magnetic nozzle is used, which comes in combination with a bat. This will provide a more secure hold of the self-tapping screw on the axis of the tool being used.

How to fix drywall with self-tapping screws: consumption per sq. m.

To attach drywall with self-tapping screws, you do not need a large set of tools:

• screwdriver;
• special magnetic nozzles;
• bit;
• self-tapping screws for metal and wood.

To fix the drywall sheet in one layer to the frame, which can be made of two materials, it is necessary to take self-tapping screws for metal, the length of which reaches 25 mm, or for wood - 32 mm.

The head of such a fastener is a countersunk carob type. When screwing in, such a self-tapping screw does not break the top layer of drywall, as it presses the edges of the cardboard into the hole. If during operation it is not possible to tighten the self-tapping screw or it bends, it must be unscrewed and replaced with a new one. It is important to remember that a self-tapping screw cannot be screwed into the same hole twice. It will be necessary to make an indent of at least 50 mm.

To reduce consumption, consider the type of screws

There are a number of mandatory requirements for installing drywall fasteners:

1. Self-tapping screws must enter the frame strictly at right angles. At the same time, it should deepen by at least one third of its length. In a frame made of a metal profile to a depth of at least 10 mm, from a wooden one - 20 mm.
2. The distance from the edge of the drywall to the fasteners must be at least 10 mm.
3. The head of the screw must be recessed into the sheet by 1 mm.
4. There should not be any foreign inclusions between the frame from any profile. If you neglect this rule, the sheet is deformed rather quickly.

Self-tapping screws tn 25 are designed for fastening the material in one layer to the frame, made using a metal profile. In this case, the thickness of drywall should not exceed 12.5 mm.

Self-tapping screws tn 35 are used for wall cladding with plasterboard. In this case, the number of layers is two.

Important! The seams of the bottom and top layers should not match. Otherwise, the design will be greatly weakened.

Important nuances of fastening self-tapping screws: how it affects consumption

Self-tapping screws tn are used for a profile whose thickness does not exceed 0.7 mm.

Self-tapping screws for wood have a pitch and angle of the thread profile greater than those of fasteners designed to work with metal. Their design contributes to a more durable fastening of drywall to wooden blocks. Wood screws cannot be replaced with metal screws, as this will weaken the finished structure. Wooden frames are sheathed with fasteners tn 35 in one layer, tn 45 - in two layers.

Drywall can also be fixed using tb self-tapping screws. Their design is similar to metal screws. The only difference is that instead of a sharp end, they are equipped with a drill, with which they drill holes in the profile up to 2.2 mm. It's perfect for when the tn for profile doesn't do the job. Such a self-tapping screw holds perfectly in a profile made of various materials.

The rate of consumption of self-tapping screws, depending on the type of plasterboard

Before deciding how many self-tapping screws are needed and calculating the consumption, it is necessary to decide on the type of drywall used to build the structure.

Drywall is divided into several types depending on the properties and purpose:

1. Ordinary drywall (gypsum plasterboard) is used only for interior decoration. With the help of such materials, walls, ceilings are lined and partitions are mounted in a room in which dry or normal humidity conditions prevail.
2. Moisture resistant drywall (GKLV) has a water absorption of less than 10%. With the help of such materials, rooms with dry or humid conditions are finished.
3. Fireproof drywall (marked as GKLO). Such drywall is intended for facing rooms in which fires are possible. This is possible due to the fact that this drywall is characterized by increased resistance to open fire.
4. Drywall GKLVO combines the properties of a moisture-resistant and fire-resistant material.

Consumption rates for self-tapping screws

When planning the transportation of goods or calculating the load of building structures, it is necessary to know the weight of Knauf drywall. Calculating it is quite simple, since the sheets have the correct geometric shape and are made of a homogeneous material with a known density. But for this you need to know the type of material and its dimensions. The weight of the sheet within one batch has a constant value.

Correctly calculate the consumption of self-tapping screws for plasterboard

You can find out how much GKL weighs based on its thickness, area and specific gravity. GOST 6266-97 regulates the mass of one millimeter of sheet thickness with an area of ​​1 m2. It depends on the type of material corresponding to the area of ​​its application. For ordinary drywall, it should be no more than 1.0 kg. For moisture-resistant, fire-resistant and moisture-fire-resistant sheets, the range is from 0.8 to 1.06 kg.

GKL weight 1 m2 is obtained by simply multiplying this figure by the thickness of the sheet. For 8.0 mm of ordinary GKL, the weight of 1 m2 is taken equal to 8.0 kg. For moisture resistant, it can be from 0.8 * 8.0 = 6.4 kg to 1.06 * 8.0 = 8.48 kg.

Consumption of self-tapping screws per 1m2 of drywall

The weight of the drywall sheet and the consumption of self-tapping screws on the wall

Knowing the weight of a unit area of ​​the drywall, it is easy to calculate how much a drywall sheet weighs. To do this, by multiplying the length of the sheet by its width, the area is obtained, which in turn is multiplied by the weight per square meter. So the weight of GKL 12.5 mm for normal use with a size of 2500x1200 mm will be no more than 2.5 * 1.2 * 12.5 \u003d 37.5 kg. For the same moisture-resistant GKL 12.5 mm, the weight can be in the range from 30 to 40 kg.

There are a large number of sizes of Knauf sheets, so how much drywall weighs is calculated for each of them independently or using the appropriate tables. For a conventional GKL, a version of the table can be presented in the following form.

GKL sheet weight: calculate the consumption of self-tapping screws

What plays an important role in repair and installation? Of course, fasteners. Due to the variety of jobs that require fixing and the materials used during repairs, a wide range of fastening products are used. In this article, we will take a closer look at the data on the consumption of self-tapping screws per drywall sheet.

Table of self-tapping screws for the ceiling

Drywall is used to create ceilings and partitions. To install sheets, you need fasteners. Self-tapping screws are excellent for this business, which will require a considerable amount.

Of course, you can save money and use fewer fasteners, but this is a fastener that requires a long service life. Note that material consumption cannot be calculated with accuracy.

The frames, which are the support for the GKL, are represented by two types: metal and wooden. There are several types of fasteners: dowel-butterfly, dowel-nail, self-tapping screws for metal and wood. Repair work cannot be imagined without self-tapping screws. They are chosen depending on what material the frame of the partition or ceiling consists of. Remember that self-tapping screws for metal and wood are not interchangeable.

The ceiling is an important part of the apartment, and therefore carefully select the materials for it. The visual difference between self-tapping screws for metal and wood is the distance between two thread ridges. It's called a step. More details on the picture.

Consumption of self-tapping screws per square meter of drywall

Correctly calculate the number of self-tapping screws for fixing the ceiling frame and partition, because if there are not enough of them, the drywall will not hold well, and if there are too many, it will crack.

Professionals recommend placing self-tapping screws at a distance of 35 cm from each other. If necessary, strengthen the structure, you can carry out fastenings and closer. The profile mounting distance should not be less than 10 centimeters. Remember that at least 10 millimeters recede from the edge, since when installed at a shorter distance from the edge of the profile, it may be destroyed. The consumption of fasteners depends on how much you need to strengthen the ceiling or partitions.

It is worth noting that a distance of 35 centimeters refers to a single-layer GKL coating. If you make a stepped ceiling or attach sheets in two layers, the parameters will change. Self-tapping screws are installed on the first sheet at a distance of 60 cm, and on the second sheet at 35 cm already known to us. This is quite enough for a good strengthening of the structure. The number of self-tapping screws per 1 m² varies from 20 to 25 pieces, but it is best to take it with a margin so as not to visit the store several times.

If you need accurate information, use the electronic calculation in the online service. Using the calculator program, calculate the consumption of fasteners and other materials that are used in the work.

But be that as it may, even electronic calculation does not guarantee that some parts will not be rejected or damaged, so purchase materials with a 15% margin.

• Direct the fasteners into the gypsum board and the frame at a right angle. This guarantees strength and reduces the chance of cracks. If the fastener enters obliquely, then the hole becomes larger, which reduces the strength of the material.
• If the self-tapping screw entered obliquely, then it should be pulled out and screwed in again.

It is important that it is forbidden to screw into the same hole twice. Step back at least 5 centimeters from the previous hole, this ensures that the plasterboard does not collapse.

An example of the location of self-tapping screws

• Keep track of how far the self-tapping screw goes. Professionals say that at least a third of the length should be in the frame. This guarantees good anchorage.
• Once the fixing is in place, check the surface for smoothness. Fasteners should not protrude, the hat is “recessed” to a depth of one millimeter. No more and no less, with a significant deviation from this parameter, there is a threat to the structure.
• When a stepped ceiling or partitions with a double layer of GKL are installed, the sheets are overlapped. In this case, the edges of the two layers should not coincide, as this reduces the stability of the structure. A similar method is used in profiled sheet fences.
• There should not be any foreign objects and materials between the GKL and the frame, since one of the disadvantages of this material is the ability to deform.

If you follow the tips for using self-tapping screws, you will get the optimal consumption of materials. It increases only due to damage to parts of the structure.

Consumption of self-tapping screws on the wall: ensure reliability

There are cases when the self-tapping screw untwisted and increased the likelihood of breakage. To avoid such problems, self-tapping bugs were invented. They are so named because, like insects, they hold well on the surface. The risk of self-unwinding is reduced to zero due to notches on the head.

Use the provided data on the consumption of self-tapping screws for calculations, then you will fix the partitions and the plasterboard ceiling properly.

Self-tapping screws: consumption per m2

Drywall has long come into use as a reliable and efficient building material. Among the mounting methods, installation on a metal frame is popular. This requires additional elements, including fasteners.

The main element with which the structural elements are connected, a drywall sheet is screwed to a metal frame, and sometimes the frame itself to the surface, is a self-tapping screw. The name itself speaks of its ability to easily screw into the surface. But when constructing structures from GKL, the correct choice of a self-tapping screw is important.

Types of self-tapping screws: correctly calculate the consumption

Types, differences of self-tapping screws

A self-tapping screw is a metal rod with a thread, a cap or head and a nose of various shapes, depending on the tasks being solved. Head with cross slot. There are self-tapping screws - universal, for wood and metal.

These fasteners differ in many ways, including the material of manufacture. It:

• High carbon steel.
• Stainless or alloy steel.
• Brass.

They are coated with phosphates (black), oxides (also black), galvanized coating (light - often white) or no coating at all. Phosphated self-tapping screws with a conical head are marked SMK, steel galvanized with a press washer - SMM. For a tree - SHD.

Self-tapping screw - frequent and rare. The first is used to work with metal. The second is for wood. A pointed nose in the form of a drill is designed for drilling into thick (up to 2 mm) metal.

Dimensions of self-tapping screws for metal and consumption rate

The main sizes of self-tapping screws used in the construction of drywall structures on a metal frame are as follows:

• Fasteners with a length of 25 mm and a diameter of 3.5 mm are used to fasten the GKL to the frame. When installing two layers of drywall, self-tapping screws 35 mm long are used. The metal of manufacture does not play a big role, but galvanized is always preferable where there is high humidity. A nose with a drill is used if the profile is more than 0.7 mm thick. Choose a self-tapping screw with a press washer. It is easier to hide under putty.
• The fastening of profiles with each other is carried out by the so-called "bugs" or "fleas" among the people. Sometimes they are called "texes" by marking TEX3.5x9.5 mm. These are self-tapping screws for metal with a hemispherical head 9.5 or 11 mm long with a sharp or drill-shaped tip. The tip-drill is used to connect a profile with a thickness of 0.7 mm or more.

How to calculate the consumption of self-tapping screws for metal

At the stage of preparation for working with gypsum boards, they acquire the appropriate metal screws. It is more profitable to do this in bulk, and they are sold in large packages of 100 or more pieces. For an approximate calculation of the required amount per square meter and the correct consumption, take into account:

• The size of the drywall sheet. As a rule, it is 1.2 by 2.5 meters.
• Attachment step. For reliable fastening, self-tapping screws are placed at a distance of 35 cm from each other. You can install more often - it all depends on the desired rigidity and durability of the structure.
• The number of layers of GCR. The second layer is fixed in increments of 35 cm or more.
• The total length of the profile and the number of connections with self-tapping screws. Each has four elements.

Consumption of self-tapping screws per 1m2 of drywall

An approximate calculation shows that about 70 pieces are required to fasten a standard sheet, and 100 pieces in two layers. Their cost is low - on average, a package (100 pieces) costs a little more than half a dollar, so to save time and nerves, they take it with a margin.

Selected with quality control packaging. It is better to purchase one pack and check the quality of the elements, and then take as much as you need. Use galvanized steel self-tapping screws (white). They are suitable for use in any type of room, with any mode of humidity and temperature.

When choosing, the appearance of the self-tapping screws is evaluated - the same dimensions, without thickenings, bends. The spouts are even, the slots are located in the center of the cap. The color of the elements is uniform, which confirms the quality of the coating. It is recommended to buy products from manufacturers with a name. Their screws on the head are marked with a Latin letter.

Consumption rate of self-tapping screws per m2: how to fasten correctly

Before sheathing with drywall, mark the position of the holes of the self-tapping screws. The step size depends on the design load on the structure and varies from 15 to 50 cm. The recommended one is 25 cm.

To work, prepare a screwdriver with various nozzles and a cross screwdriver. For convenience, use a magnet or magnetic tape to hold several items at once. This will speed up the process - both hands are often busy in work. Masters for these purposes use special belts with pockets for various fasteners.

In order to securely fasten the GKL to the frame, put a self-tapping screw on the nozzle, place the screwdriver strictly perpendicular to the surface of the sheet and completely screw the self-tapping screw into the sheet with a recess of 1 mm, no more. In this case, the cone head makes a funnel in the drywall sheet and holds the sheet firmly.

Skewing should not be allowed - this will weaken the fasteners, plus when finishing, the spatula will cling to the edge of the head. Excessive screwing will cause deformation of the sheet, which is also a marriage. The screw will tear the paper cover and will only hold on to the gypsum core of the sheet. Gypsum will wash out over time and the mount will weaken.

In such cases, the self-tapping screw is unscrewed, if necessary, changed and twisted again 5 cm from the previous place of screwing. The hole is plastered. It is not recommended to screw the self-tapping screw closer than 1 cm to the corner or edge of the sheet.

The video shows how to properly screw metal screws:

How to check the result: the correct consumption of self-tapping screws

To determine whether all the screws have entered to a sufficient depth, you can run a spatula over the surface - it should not cling to anything.

They are screwed in with a screwdriver, first at maximum speed, and after the self-tapping screw enters the sheet halfway, the speed is reduced to a minimum. The screwdriver works smoothly, without strong pressure. When working with a screwdriver, it is important to use a quality bit, otherwise you will break the part and increase consumption. Self-tapping screws for metal are taken only with a countersunk head.

When a profile is screwed to the drywall, the self-tapping screws are screwed in a “herringbone” - at an angle to the left, at an angle to the right, etc. In this case, the screws into the metal should not be screwed all the way, but before the start of the conical part. This ensures the distribution of the load along the profile - he himself presses the gypsum with his area. The strength of such a compound increases by one and a half times.

One of the integral elements of almost any modern repair are drywall constructions. This, and only nothing surprising, because this material allows you to build a wide variety of partitions, abut certain functional areas, equip original multi-level ceilings and quickly complete an even formation for wall decoration.

Among the main advantages of drywall constructions, it makes sense to highlight:

• light weight and easy installation;
• good ductility of the material for processing;
• the minimum abundance of garbage generated in the process of work;
• high heat and sound insulation characteristics;
• environmental friendliness, safety for health;
• non-flammable;
• low cost.

One of the few disadvantages of using drywall is the importance of using various types of profiles and screws, as well as dowels, reinforcement mesh, putty and primer, hangers and connecting elements. Moreover, all this must be purchased in sufficient quantities, for which it is also appropriate to determine the amount of drywall required for the construction of a certain partition, wall or ceiling. It is easier to calculate this, knowing the approximate consumption of drywall and materials, take 1m2 of certain structures.

The tables below will show the consumption rates of drywall in 1 m2 of partition structures, wall and ceiling finishes.

Beat pocket putty and primer for drywall

The main purpose of applying a primer to a ceiling or wall surface is to increase the strength of the base and improve adhesion for a stronger adhesion of the finishing material to the plasterboard surface. As a rule, the treatment of drywall is carried out with an alkyd primer. About 100 milliliters of the substance is consumed per 1 square meter of surface. If the primer is made on top of the putty, it is advisable to use facade primer, the consumption of which is 130-150 milliliters per 1 square meter.

How much (money) putty comes out largely depends on how thick the tropopause superimposed in the process of work has. As a rule, the average consumption level per 1 square meter is at the level of 1 kilogram of material. So, if a false ceiling is processed in a room, in addition to high humidity, then you will have to spend 1.15 kilograms per individual square meter. Closing cracks and other minor defects, you can use the gypsum-based material, which will require 850 grams per square meter. In the final stage, glue-type putty is often used, the consumption of which is 500 grams, get a “square”.

Often, drywall manufacturers themselves supply special materials to the market, designed to please anyone) of its finish. As a rule, the consumption of putty and primer for drywall, produced by one brand, is slightly lower than in the case of using materials from other companies.

Expendable article of self-tapping screws for drywall

Fastening drywall sheets to the profile, as a rule, is done using self-tapping screws, the step between which should be 30 centimeters. Sometimes, in order to increase the strength of the structure, they resort to reducing the step to 10 centimeters.

It is extremely important to remember that fastening screws closer than 10 mm to the edge of the sheet is not possible, as this can cause cracking.

In order to determine the approximate consumption of self-tapping screws, it is necessary to take into account several different parameters:

• Plasterboard size. Its standard measure is 1200 by 2500 millimeters. Non-standard panels are also produced, having a size of 600 and 2000 millimeters. But, since the first option is more common, it is he who, as a rule, is taken as the basis for making calculations.
• Attachment distance. According to experts, drywall sheets should be fixed with a 35-centimeter step. This is what allows the finished structure to have a high level of strength, reliability and durability.
• Composition of plasterboard layers. In the case of installing drywall in several layers, fastening should be done with different steps. For example, the first layer is attached with a 60 cm step, and the second with a 35 cm step.

After the mandatory indicators are determined, it is possible to easily calculate the consumption of self-tapping screws for drywall for attaching the sheet. Get one sheet will need approximately 70 pieces, while two layers will require a minimum of 110 pieces in the image.

Drywall adhesive consumption

When carrying out interior decoration using drywall, the casing of sheets can be carried out not only with self-tapping screws, but also with glue. In this relationship, it is necessary to know the consumption of drywall adhesive. In the case of using the popular mounting mixture Perlifix, how much (money) comes out will be at the level of 5 kilograms per square meter (plus it’s good to add a certain amount for inevitable losses).

In order for the mixture to be used more economically, it is necessary to carry out the correct preparation of the base for the use of glue. First of all, you should make sure that it is dry and has an unfavorable temperature of less than plus 5 degrees. The surface must be cleaned of dirt and dust deposits, delaminations, residues of formwork lubricants and other contaminants; if necessary, it can be washed. After that, possible protrusions should be eliminated.

When working with highly absorbent surfaces, such as sand-lime brick, aerated concrete, plaster, it is necessary to apply a primer with a roller, brush or sprayer. In the case of highly saturated surfaces, priming provides an increase in adhesive properties, as a result of which the mounting pulp will more reliably adhere to the wall or ceiling. In the process of drying the primed surface, nothing can be done to ensure that dust does not get on it.

The adhesive pulp is prepared as follows:

The plastic tank is filled with clean water at the rate of fifteen to sixteen liters per 30 kg bag of dry mix. After that, mounting glue is poured into the water and it is thoroughly mixed using a construction mixer in front until a homogeneous porridge-like mass is formed. It is not necessary to add any other components to this mixture, as this may adversely affect its strength. It is impossible to work with the resulting solution at a fast pace, since after about half an hour after preparation, the beloved will begin to harden.

Paint consumption for drywall

When coating plasterboard sheets with paint, as a rule, a water-based emulsion is used. Most often it is sold in white, tea, if desired, you can add special dyes to it, which will give it the required blueness. Paint of this type is suitable for use in any premises, and allows you to get a surface of a glossy or matte type. This point should be taken into account in advance when purchasing paint. The advantage of the matte version is that it allows you to hide various kinds of defects, while the gloss, on the contrary, will further emphasize possible sins, therefore, in this case, extreme caution and accuracy are required at the preparation stage.

Desirably, one of the main distinguishing features of water-based paint is the ability to quickly and easily give it the required texture, for which long-haired rollers can be used, or special curly ones.

Estimated paint consumption for drywall is 1 liter on top for every 5 square meters of area. The exact information about this can be recognized on the packaging of the material.

In addition to water-based paint, you can also use water-based acrylic paint. It is especially recommended to use it in rooms that are characterized by increased moisture content, since this paint is able to maintain its original appearance when exposed to moisture.

Acrylic paint also allows you to give the surface a soft or glossy look. As for the texture, it is important to achieve it more difficult than when using a water-based emulsion. The approximate consumption of acrylic paint for gypsum board is 1m2, which is about 0.2 liters per 1 square meter.

Important! The following consumption rates for CD and CW profiles are focused on the use of profiles with a steel thickness of 0.55-0.6 mm. When using profiles with a smaller steel thickness, their number must be increased by 30%. This is due to the fact that profiles with a steel thickness of less than 0.55 mm must be installed after 40 cm, while with a standard steel thickness (standard = 0.6 mm), profiles are installed after 60 cm. Accordingly, the number of fasteners and connecting elements increases etc.

Therefore, you need to understand that buying cheap profiles will most likely cost you more than buying more expensive profiles of standard thickness.

Do you want to do your own calculations?

in repair supplies?

Before you go to the store, you would certainly like to study for yourself what and how much to buy. If so, then...

We provide you with the opportunity to make all the necessary calculations with the help of special tables in Excel in just a few seconds. You only need to know the initial data (length, width, height). Then you select the desired structure (ceilings, partitions, walls, etc.) and enter your dimensions. And all the calculations are ready!
