Frame consumption per 1m2 of drywall. Consumption of materials for plasterboard structures. How to properly fasten drywall with self-tapping screws: consumption per sq. m

One of the integral elements of almost any modern renovation is 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 finishing walls.

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 importance of using various types of profiles 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 adhesion of the finishing material to the plasterboard surface. As a rule, drywall is treated with an alkyd primer. About 100 milliliters of substance are consumed per 1 square meter of 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, then you will have to spend 1.15 kilograms per individual square meter. When filling 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 fastened in 35-centimeter increments. This is what allows the finished structure to have a high level of 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 carrying out interior finishing using 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 properly prepare 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, peelings, form lubricant residues and other contaminants; if necessary, it can be washed. After this, any protrusions should be eliminated.

When working with surfaces that strongly absorb moisture, 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:

The plastic tank is filled with clean water at the rate of 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, if desired, you can add special dyes to it that 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. The advantage of the matte version is that it allows you to hide various types 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.

Of course, 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-pile rollers or special shaped rollers 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 water-based acrylic paint. 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. The approximate consumption of acrylic paint for 1 m2 on drywall is the same as the previous option, that is, it is equal to approximately 0.2 liters per 1 square meter.

The construction of plasterboard structures begins with the design and calculation of the amount of purchased material. It’s easy to find out the number of profiles and gypsum boards, but determining how many fasteners will be required is more difficult. Let's find out how to count the number of screws per sheet of drywall.

What kind of screws are used when installing gypsum boards?

To fasten drywall to the frame, screws of different lengths are used:

• 25 mm – when installing plasterboard in one layer;
• 35 mm – with two layers of sheathing.

The type of screws is selected based on the frame material:

• the cladding is attached to the profile with metal screws;
• to the beam - on wood.

It is easy to distinguish them: hardware intended for working with metal have more frequent threads.

You should not use one type of screws instead of another: this will certainly affect the strength of the fastening.

The design of the fastener ensures convenience and quality of work:

• Hardware is protected from corrosion by a special coating that gives it a black color.
• The pointed spiral of the thread ensures easy penetration of the self-tapping screw into the metal profile and reliably holds it there in the future.
• The conical head is recessed into the material and does not interfere with subsequent finishing.
• The deep cross-shaped slot on it allows you to screw in a self-tapping screw with a regular screwdriver or screwdriver.

When using a screwdriver, you need to act carefully: there is a high risk of sinking the screw too deep and damaging the material. Makes work easier: due to its design, it limits the depth of screwing in the hardware.

Professionals use . They make the process of installing drywall sheets much easier and faster. But the cost of such a tool is high, so there is no point in purchasing it for a single repair.

Before calculating how many self-tapping screws will be needed for a structure, it is logical to familiarize yourself with the norms and rules for their placement. The following nuances are taken into account:

• The distance between adjacent screws must be more than 10 cm, otherwise the plaster of the sheet will begin to crumble when screwed in.
• When leveling walls or installing partitions, a step of 25–35 cm is taken between the fastening points. It is reduced to 15–20 cm if in the future it is planned to cover the surface with heavy material, such as ceramic tiles.

• More hardware is used for the ceiling sheathing, since they are attached more often: the step is 15–20 cm. The rule works here: the thicker and heavier the drywall, the smaller the distance between the attachment points.
• When installing in two layers, the first one is attached less frequently - every 45–60 cm. The screws that secure the second layer are 10 cm longer. When screwed in, they additionally secure the first one. This reduces the consumption of hardware and eliminates unnecessary costs.
• The number of required attachment points increases when constructing curved structures. Here the pitch between the screws is chosen so as to fix the desired surface shape.

Calculation of the number of screws

It is produced according to the frame diagram drawn up. It is clear that the number and dimensions of the guides, as well as the jumpers between them, will be individual for each case. General recommendations are as follows:

• For walls, the distance between the guides is 40 or 60 cm. This step allows you to place the joints of the sheets on the surface of the profile.

• The number of horizontal jumpers depends on the dimensions of the room (one sheet of drywall is often not enough in height), as well as on the requirements for structural rigidity (mandatory when constructing partitions, but can be neglected when leveling walls).
• For ceiling structures, frames are constructed in the form of cells with dimensions of 40 × 40, 40 × 60 or 60 × 60 cm. This structure ensures a minimum of trimmings and joining of elements on the profile.

• 11 self-tapping screws for each rack (the sheet is positioned vertically, its length is 2,500 mm, the fastening pitch is 25 mm).
• For 4 racks – 44 screws.
• Plus 6 - for fastening to the upper and lower horizontal jumpers (three for each - just place one self-tapping screw between adjacent vertical posts).
• In total, 50 pieces will be needed per sheet.

The issue of calculating consumables is very important when installing gypsum board partitions. In order to correctly and quickly calculate the amount, you will need our calculator. GCR calculator for partitions has a simple interface and requires a minimum of data for accurate calculation of building materials. Let's look at how to use this calculator correctly and measure surfaces for installing a partition.

We take measurements.

It is impossible to calculate the material without first knowing the parameters of the partition. To determine them you will need a regular tape measure. To calculate the gypsum board, only two quantities are needed - the length and height of the future partition. We measure them using a tape measure and write them down on a piece of paper.

We make a calculation.

Calculation of plasterboard partitions calculator performs according to three main parameters:

• length;
• height;
• type of cladding (single-layer or two-layer).

Note:

If the height of the room is greater than the maximum height of the drywall sheet (3 meters), then the calculator calculates the materials according to the consumption, which is indicated in square brackets. This is due to the fact that there is a need to create jumpers from the profile at the joining points, as well as its subsequent finishing.

If the height of the ceiling of the room is up to 2.5 meters, then the calculator counts plasterboard sheets in pieces measuring 1.2x2.5 m (S = 3m2), and if the height is over 2.5 m - sheets of 1.2x3 m (S = 3.6m2 ).

Having made preliminary measurements, you can enter the data into the form. Our calculator allows you to calculate not only the amount of drywall, but also other materials necessary for the construction of the partition - guides, screws, putty, primer, etc. Thus, already at the first stage of the preparatory work you will be able to see how much money will be needed to erect the partition and on what it will be possible to save money.
