One of the integral elements of almost any modern renovation are plasterboard structures. This is nothing surprising, because this material allows you to build a wide variety of partitions, support certain functional areas, arrange original multi-level ceilings and quickly create an even formation for wall decoration.
Among the main advantages of plasterboard structures, it makes sense to highlight:
- light weight and ease of installation;
- good flexibility of the material for processing;
- minimal amount of waste generated during the work process;
- high heat and sound insulation characteristics;
- environmental friendliness, safety for health;
- not subject to combustion;
- low cost.
One of the few disadvantages of using drywall is the essential nature of the application. various types profile and screws, as well as dowels, mesh for reinforcement, putty and primer, hangers and connecting elements. Moreover, all this must be purchased in sufficient quantities, for which it is also necessary to determine the amount of drywall required for the construction of a certain partition, wall or ceiling. It is easier to calculate this if you know the approximate consumption of drywall and materials, take 1 m2 of certain structures.
The tables below show the consumption rates of plasterboard per 1 m2 of partition structures, wall and ceiling decoration.

Hit your pocket with 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 stronger quality adhesion finishing material with plasterboard surface. As a rule, drywall is treated with an alkyd primer. On 1 square meter About 100 milliliters of the substance are consumed on the surface. If the primer is applied over putty, it is advisable to use façade primer, the consumption of which is set at 130-150 milliliters per 1 square meter.
How much putty comes out (of money) largely depends on the thickness of the tropopause applied during the work. As a rule, the average consumption level per 1 square meter is at the level of 1 kilogram of material. So, if you are treating a suspended ceiling in a room in addition to high humidity, you will have to spend 1.15 kilograms per individual square meter. Repairing cracks and other minor defects, you can use a gypsum-based material, which will require 850 grams per square meter. At the final stage, adhesive-type putty is often used, the consumption of which is 500 grams per square meter.
Often, the plasterboard manufacturers themselves supply the market with special materials intended for the purpose of finishing it. As a rule, the consumption of putty and primer for drywall produced by one brand is slightly lower than when using materials from other companies.
Consumable item for self-tapping screws for drywall
Attaching plasterboard sheets to the profile is usually done using self-tapping screws, the pitch between which should be 30 centimeters. Sometimes, in order to increase the strength of the structure, they resort to reducing the pitch to 10 centimeters.
It is extremely important to remember that fastening screws closer than 10 mm to the edge of the sheet is impossible, as this may cause cracking.
In order to determine the approximate consumption of self-tapping screws, it is necessary to take into account several different parameters:
- Size of plasterboard sheet. Its standard measurement is 1200 by 2500 millimeters. Non-standard panels are also produced, ranging in size from 600 to 2000 millimeters. But, since the first option is more common, it is, as a rule, what is taken as the basis when making calculations.
- Mounting distance. According to experts, plasterboard sheets should be fixed in 35-centimeter increments. This is what allows the finished structure to have high level strength, reliability and durability.
- Composition of plasterboard layers. If plasterboard is installed in several layers, fastening should be done in different increments. For example, the first layer is attached with 60-centimeter increments, and the other with 35-centimeter increments.
Once the required indicators have been determined, you can easily calculate the consumption of self-tapping screws on drywall for fastening the sheet. One sheet will require approximately 70 pieces, while two layers will require at least 110 pieces.
Drywall adhesive consumption
When implementing interior decoration With the use of plasterboard, planting sheets can be done not only with self-tapping screws, but also with glue. In this regard, it is necessary to know the consumption of drywall adhesive. In the case of using the popular Perlifix mounting mixture, how much money comes out will be at the level of 5 kilograms per square meter (plus it is 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 proper preparation base for the sake of using 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, peelings, form lubricant residues and other contaminants; if necessary, it can be washed. After this, any 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 using a roller, brush or sprayer. In the case of highly saturated surfaces, priming provides increased adhesive properties, as a result of which the mounting pulp will adhere more reliably to the wall or ceiling. While the primed surface is drying, there is nothing you can do to ensure that no dust gets on it.
The adhesive pulp is prepared as follows:
Plastic tank being filled clean water based on fifteen to sixteen liters per 30-kilogram bag of dry mixture. Afterwards, the construction adhesive is poured into the water and thoroughly mixed using a construction mixer until a homogeneous porridge-like mass is formed. There is no need to add any other components to this mixture, as this may negatively 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, water-based emulsion is usually used. Most often it is sold in white color; tea can be added to it if desired. special dyes, which will give it the required blueness. This type of paint is suitable for use in any premises, and allows you to obtain a glossy or matte surface. This point should be taken into account in advance when purchasing paint. Advantage matte version in that it allows you to hide various kinds of defects, while gloss, on the contrary, will further emphasize possible sins, so in this case extreme caution and accuracy are required at the preparation stage.
Hopefully, one of the main distinctive features water-based paint, it is possible to quickly and easily give it the required texture, for which rollers with long pile or special shaped ones can be used.
The approximate paint consumption for drywall is 1 liter on top for every 5 square meters of area. Precise information about this can be found on the packaging of the material.
In addition to water-based paint, you can also use acrylic paint for water based. It is especially recommended to use it in rooms characterized by high moisture content, since this paint is able to retain its original appearance when exposed to moisture.
Acrylic paint also allows you to give the surface a dull or glossy look. As for the texture, it is more difficult to achieve it than when using a water-based emulsion. Approximate consumption acrylic paint Keep 1m2 of drywall the same as the previous option, that is, equal to approximately 0.2 liters per 1 square meter.
Hi all! It's no secret that I love making repairs with my own hands 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 from friends, but incorrectly determined the consumption of self-tapping screws needed per square meter. m. GKL. And since we were tidying up Vacation home, I had to stop work and go to a local store. I won’t talk about overpayments, but the loss of time was noticeable. To avoid this prospect, study the calculation rules and purchase required quantity self-tapping screws!
Anyone who has decided to make repairs using plasterboard sheets wonders how many self-tapping screws will be needed for 1 m2 of plasterboard panel. As a rule, there is no definite 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, and a step of 30 cm is observed. If you need to increase the strength of the structure, the step is reduced to 10 cm.
Important! Self-tapping screws should never be fixed 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 screws you will need, you need to consider several parameters:
GCR size: it is released in standard sizes— 1200x2500 mm. In addition, there are non-standard panels, the size of which is 600x2000 mm. To calculate the approximate number of screws, you need to take the first option, since it is more common.
- Mounting step. Experts recommend attaching gypsum boards in increments of 35 cm, as this indicator can ensure the durability and reliability of the finished structure.
- Number of layers of drywall. If a decision has been made to install drywall in several layers at once, the screws must be fastened at different pitches. For example, the first layer will be attached every 60 cm, and the second every 35 cm.
Having decided on the required indicators, you can correctly calculate required amount self-tapping screws to attach the gypsum board. It will take approximately 70 pieces for one sheet, and at least 110 for two layers. By choosing a certain fastening step and the number of panels for the manufacture of the 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 various sizes, types and characteristics of coverage. These include screws for metal, wood, dowel-nails, butterfly dowels and many others. Most often, both for wooden and metal profile, 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 in two types protective coating, namely phosphate and zinc. Their head has a hemispherical or semicylindrical shape. It is equipped with a Philips slot No. 2, designed for a cross-shaped bit attachment.
The base of the heads on the thread side is equipped with notches. This allows you to protect the fastening from possible self-unscrewing. The thread pitch of such self-tapping screws is very frequent, which is what distinguishes them from other representatives of fasteners intended for fastening drywall. Such fasteners are also called self-tapping screws. It is one of the most popular fasteners available on the modern construction market.
There are several types of such products:
- Self-tapping screws with a drill are used to fasten a profile whose thickness reaches 2 mm. With their help, fastening is carried out without any serious problems. The most important thing is to adjust the tightening force of the screwdriver. This is required to prevent stripping of the thread in the profile. For getting best result It is recommended to use a high-quality bit attachment, which perfectly aligns its own axis with the axis of the screw. In addition, it firmly holds fastener when twisting the profile without deforming the fastening slot. For each type of screws used for fastening both metal and wooden profile, documentation from manufacturers provides information that talks about recommended tightening forces.
- Self-tapping screws with a sharp end make it possible 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 helps preserve its structure. Recommendations for choosing the appropriate tool and choosing an attachment are the same as in the first case.
To better secure the plasterboard, in some cases an additional magnetic attachment is used, which comes in combination with a bat. This will ensure more reliable retention of the self-tapping screw on the axis of the tool being used.
How to properly fasten drywall with self-tapping screws: consumption per sq. m.
To attach drywall using self-tapping screws, you do not need a large set of tools:
- screwdriver;
- special magnetic attachments;
- bat;
- screws for metal and wood.
To fasten a plasterboard sheet in one layer to a frame, which can be made of two materials, you need to take screws for metal, the length of which reaches 25 mm, or for wood - 32 mm.
The head of such a fastening element is a secret horn type. When screwed in, such a self-tapping screw does not tear upper layer drywall, as it presses the edges of the cardboard into the hole. If during operation it is not possible to tighten the screw or it bends, it must be unscrewed and replaced with a new one. It is important to remember that you cannot screw a self-tapping screw 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:
- Self-tapping screws must enter the frame strictly at right angles. In this case, it must deepen by at least one third of its length. In a metal profile frame to a depth of at least 10 mm, in a wooden frame - 20 mm.
- The distance from the edge of the drywall to the fasteners should be at least 10 mm.
- The head of the screw should be recessed into the sheet by 1 mm.
- There should not be any foreign inclusions between the frame made of any profile. If you neglect this rule, the sheet will deform quite quickly.
Self-tapping screws tn 25 are designed for fastening material in one layer to a frame made using a metal profile. In this case, the thickness of the drywall should not exceed 12.5 mm.
Self-tapping screws tn 35 are used for cladding walls with plasterboard. In this case, the number of layers is two.
Important! Seams of the lower and top layers should not match. Otherwise, the structure will be greatly weakened.
Important nuances of fastening self-tapping screws: how does this affect consumption
Tn self-tapping screws are used for profiles whose thickness does not exceed 0.7 mm.
Wood self-tapping screws have a pitch and thread profile angle greater than those of fasteners designed for working with metal. Their design promotes more durable fastening of drywall to wooden blocks. Wood screws cannot be replaced with metal screws, as this will weaken the finished structure. Fastening elements tn 35 are used to cover wooden frames in one layer, tn 45 - in two layers.
Drywall can also be attached using tb 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 ideal for those times when profile tn isn't doing the job. This self-tapping screw holds perfectly in profiles made of various materials.
Cost rate for self-tapping screws depending on the type of gypsum plasterboard
Before deciding how many self-tapping screws you will need and calculating the consumption, you need to decide on the type of gypsum board used to construct the structure.
Drywall is divided into several types depending on its properties and purpose:
- Ordinary drywall (GKL) is used only for interior decoration. With the help of such materials, walls, ceilings are lined and partitions are installed in a room in which dry or normal humidity prevails.
- 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.
- Fire-resistant plasterboard (marked as GKLO). This type of drywall is intended for cladding rooms where fires may occur. This is possible due to the fact that this drywall is characterized by increased resistance to open fire.
- GKLVO plasterboard combines the properties of moisture-resistant and fire-resistant material.
Consumption rates for self-tapping screws
When planning the transportation of goods or calculating the load building structures you need to know the weight of Knauf drywall. It is quite simple to calculate it, since the sheets have the correct geometric shape and are made of a homogeneous material with a known density. But to do 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 gypsum boards You can find out how much plasterboard 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 set from 0.8 to 1.06 kg.
The weight of gypsum board 1 m2 is obtained by simply multiplying this figure by the thickness of the sheet. For 8.0 mm conventional plasterboard, 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 1 m2 of drywall
The weight of a sheet of drywall and the consumption of self-tapping screws on the wall
Knowing the weight of a unit area of plasterboard, it is easy to calculate how much a sheet of drywall weighs. To do this, multiply the length of the sheet by its width to obtain the area, which in turn is multiplied by the weight per square meter. So the weight of a 12.5 mm gypsum plasterboard for a regular purpose with a size of 2500x1200 mm will be no more than 2.5 * 1.2 * 12.5 = 37.5 kg. The same moisture-resistant gypsum board 12.5 mm weight can range from 30 to 40 kg.
There are a large number of standard sizes of Knauf sheets, so how much drywall weighs is calculated for each of them independently or using the appropriate tables. For a regular gypsum board, a version of the table can be presented in the following form.
GKL sheet weight: calculate the consumption of screws
What plays an important role in repair and installation? Of course, fastenings. 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 detailed look at the data on the consumption of self-tapping screws per sheet of drywall.
Consumption table for ceiling screws
Drywall is used to create ceilings and partitions. To install the sheets, you need fasteners. Self-tapping screws are perfect for this task, of which you will need a considerable amount.
Of course, you can save money and use fewer fasteners, but we're talking about about the fastening from which it is required long term services. Please note that material consumption cannot be accurately calculated.
The frames that support the gypsum boards are available in two types: metal and wood. There are several types of fastenings: butterfly dowel, dowel-nail, screws for metal and wood. It’s impossible to imagine without self-tapping screws renovation work. They are selected depending on what material the frame of the partition or ceiling consists of. Remember that screws for metal and wood are not interchangeable.
Ceiling - an important part apartment, and therefore carefully select materials for it. The visual difference between self-tapping screws for metal and wood is the distance between the two thread ridges. This is called a step. More details in the picture.
Consumption of self-tapping screws per square meter of drywall
Correctly calculate the number of screws for attaching 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 screws at a distance of 35 cm from each other. If it is necessary to strengthen the structure, fastenings can be made closer. The profile fastening distance should not be less than 10 centimeters. Remember that at least 10 millimeters deviate from the edge, since if installed at a smaller distance from the edge of the profile, it may be destroyed. The consumption of fasteners depends on how much the ceiling or partitions need to be strengthened.
It is worth noting that the distance of 35 centimeters refers to a single-layer gypsum board coating. If you make a stepped ceiling or attach sheets in two layers, the parameters will change. On the first sheet, self-tapping screws are installed at a distance of 60 cm, and on the second at the already known 35 cm. This is quite enough to strengthen the structure well. The number of self-tapping screws per 1 m² varies from 20 to 25 pieces, but it is best to take a spare so as not to visit the store several times.
If you need accurate information, use the electronic calculation in the online service. Using a calculator program, the consumption of fasteners and other materials used in the work is calculated.
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% reserve.
- Direct the fasteners into the plasterboard and frame at a right angle. This ensures strength and reduces the likelihood of cracks. If the fastener enters obliquely, then the hole becomes larger, which reduces the strength of the material.
- If the self-tapping screw goes in askew, then you should pull it out and screw it in again.
The important thing is that screwing into the same hole twice is prohibited. Step back at least 5 centimeters from the previous hole, this will ensure that the plasterboard does not collapse.
Example of screw location
- Watch how far the screw goes. Professionals say that at least a third of the length should be in the frame. This guarantees good fixation.
- Once the fastener is in place, check the surface for smoothness. The fasteners should not protrude; the cap should be “recessed” to a depth of one millimeter. No more and no less; with a significant deviation from this parameter, a threat to the structure arises.
- When installing a stepped ceiling or partitions with a double layer of gypsum plasterboard, the sheets are laid overlapping. 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 fences made of corrugated sheets.
- There should not be any foreign objects or materials between the gypsum board and the frame, since one of the disadvantages of this material- ability to deform.

If you follow the tips for using self-tapping screws, you will get 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 known cases when the self-tapping screw unscrewed and increased the likelihood of failure. To avoid such problems, self-tapping screws were invented. They are so named because, like insects, they adhere well to surfaces. The risk of self-unwinding is reduced to zero due to the notches on the head.
Use the data provided on the consumption of self-tapping screws for calculations, then you will secure the partitions and plasterboard ceiling properly.
Self-tapping screws: consumption per m2
Drywall has long come into use as a reliable and effective construction material. Among the installation methods, installation on a metal frame is popular. It requires additional elements, including fasteners.
The main element with which structural elements are connected, a sheet of drywall 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 a surface. But when constructing structures from gypsum plasterboard it is important right choice self-tapping screw
Types of self-tapping screws: calculate the consumption correctly Types and differences of self-tapping screws
A self-tapping screw is a metal rod with a thread, a cap or head and a spout different shapes depending on the tasks being solved. Head with a cross slot. There are self-tapping screws - universal, for wood and metal.
These fasteners differ in many respects, including the material of manufacture. This:
- High carbon steel.
- Stainless or alloy steel.
- Brass.
They are coated with phosphates (black), oxides (also black), galvanized (light - often white) or without coating at all. Phosphated self-tapping screws with a conical head are marked SMK, galvanized steel screws with a press washer - SMM. For wood - SRS.
Self-tapping threads are common and rare. The first is used for working with metal. The second is for wood. The pointed nose in the form of a drill is designed for drilling into thick (up to 2mm) metal.
Dimensions of screws for metal and consumption rate
The main standard sizes of self-tapping screws used in the construction of plasterboard structures on a metal frame are as follows:
- To attach the gypsum board to the frame, fasteners with a length of 25 mm and a diameter of 3.5 mm are used. 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 high humidity. A spout 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 it under putty.
- Fastening the profiles to each other is carried out using so-called “bugs” or “fleas” among the people. Sometimes they are called “tex” by marking TEX3.5x9.5 mm. These are metal screws with a hemispherical head 9.5 or 11 mm long with a sharp or drill-shaped tip. The drill tip is used to connect profiles with a thickness of 0.7 mm or more.
How to calculate the consumption of screws for metal
At the stage of preparation for working with gypsum boards, appropriate metal screws are purchased. 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 quantity per square meter and the correct consumption, take into account:
- Drywall sheet size. As a rule, it is 1.2 by 2.5 meters.
- Mounting step. For reliable fastening, the screws are placed at a distance of 35 cm from each other. You can install it more often - it all depends on the desired rigidity and durability of the structure.
- Number of gypsum board layers. The second layer is attached in increments of 35 cm or more.
- The total length of the profile and the number of connections with self-tapping screws. Each one takes four elements.
Consumption of self-tapping screws per 1 m2 of drywall
An approximate calculation shows that to attach a standard sheet you will need about 70 pieces, and two layers - 100 pieces. Their cost is low - on average, a package (100 pieces) costs just over half a dollar, so to save time and nerves, take it in reserve.
Selected with quality control of packaging. It is better to buy one pack and check the quality of the elements, and then take as much as you need. Use galvanized steel screws (white). They are suitable for use in any type of room, with any humidity and temperature conditions.
When choosing they evaluate appearance self-tapping screws - same sizes, without thickening or bending. The noses 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 screw them correctly
Before covering with plasterboard, mark the position of the screw holes. The step size depends on the designed load on the structure and varies from 15 to 50 cm. The recommended one is 25 cm.
For work, prepare a screwdriver with various attachments and a cross-head screwdriver. For convenience, use a magnet or magnetic tape to hold several elements at once. This will speed up the process - both hands are often busy when working. For these purposes, craftsmen use special belts with pockets under various elements fasteners
In order to securely screw the gypsum board to the frame, put a self-tapping screw on the nozzle, position 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 sheet of drywall and holds the sheet firmly.
You must not allow it to skew - 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 defect. The screw will break paper covering and will only hold onto the gypsum core of the sheet. The plaster will erode over time and the bond will weaken.
In such cases, the self-tapping screw is unscrewed, if necessary, replaced and re-twisted 5 cm from the previous screw-in point. The hole is filled with putty. It is not recommended to screw the screw closer than 1 cm to the corner or edge of the sheet.
The video shows how to properly screw in metal screws:
How to check the result: correct consumption of screws
You can determine whether all the screws have entered to a sufficient depth by running a spatula along the surface - it should not cling to anything.
Screw in using a screwdriver first with maximum speed, and after the self-tapping screw enters the sheet halfway, the speed is reduced to minimum. The screwdriver works smoothly, without strong pressure. When working with a screwdriver, it is important to use a high-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 drywall, the screws are screwed in a “herringbone pattern” - tilted to the left, tilted to the right, etc. In this case, the screws should be screwed into the metal not all the way, but to the beginning of the conical part. This ensures the distribution of the load along the profile - it itself presses the plaster with its area. The strength of such a compound increases by one and a half times.
The main attribute of almost any renovation, especially European-quality renovation, is plasterboard structures. And this is not surprising. Indeed, from gypsum plasterboard (GVL) it is now possible to “blind” practically any partition or ceiling. For example, for a device multi-level ceiling Drywall is most often used.
In addition, these structures are quickly erected and are relatively inexpensive. True, there is one drawback here - a rather large range. So, if you decide to independently build partitions and a ceiling from gypsum plasterboard sheets in your apartment, and at the same time comply with all technology, then you will have to stock up on more than one type of profile and screws. You will also need dowels, reinforcing mesh, putty, primer, hangers and connecting elements.
All this must be purchased in the required quantity (or with a small margin) for a given design. And to do this, you need to calculate the required amount of drywall and profile for the ceiling or wall (partition). Therefore, for those who want to build similar structures, this page was created, which presents an approximate material consumption for the most common plasterboard structures:
- ceiling;
- wall structures;
- partitions.

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 thinner 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 every 40 cm, whereas when standard thickness steel (standard = 0.6 mm), profiles are installed every 60 cm. Accordingly, the number of fasteners, connecting elements, etc. increases.
Therefore, you need to understand that buying cheap profiles will most likely cost you more than buying more expensive profiles of standard thickness.
