Drywall adhesive: selection criteria

Among the variety of modern materials for construction, which are used for wall decoration, drywall is deservedly popular. Such a choice of most buyers and builders is based on the fact that it has a lot of advantages, among which environmental friendliness and a perfectly flat surface after finishing are especially distinguished. This material shows itself perfectly in contact with finishing materials, if the glue is selected correctly.

To reduce the cost of installing drywall sheets using profiles, there is an alternative way of performing these works, which involves the purchase of special glue.

In addition to its main purpose, drywall glue can be used for:

• fastening of mineral insulation;
• gypsum panels;
• aerated concrete slabs;
• materials from expanded polystyrene.

GKL glue is a product that is used only for interior work. Like any building material, the composition has advantages, among which ease of use and quick installation stand out. The surface for pasting with drywall sheets does not need to be pre-leveled, it is enough to clean it from dirt. This composition is economical. By giving preference to this method of installing products, you can save money and the amount of glue in comparison with work involving the use of profiles. Work with such a multifunctional composition will allow you to obtain high quality and durability of interior decoration in the room.

The characteristics of the adhesive solution directly depend on its composition.

Assembly adhesive requires strict adherence to the instructions for its preparation. Manufacturers indicate this information directly on the packaging. Work with him is performed with a spatula. The composition is applied to the surface in a circular motion. The intervals between strokes should be 15 to 30 cm.

When gluing the gypsum board under special control, there should be a uniformity of their installation. For this, a building level is used. If necessary, you can correct the location of the drywall sheets, but no later than 10-15 minutes after the material is glued to the surface. Mounting adhesive for gypsum board was originally used as a tile composition. However, due to its moisture resistance, environmental friendliness and resistance to low temperatures, the composition is considered universal.

Work with polyurethane foam is carried out according to the following technology:

• make 8-9 holes in the sheet, drill around each;
• pieces of foam rubber are glued to the panel, leaving a gap from the holes at a distance of 10 cm;
• the sheet is attached to the wall with screws and washers;
• the composition is poured into the holes;
• the washers are removed;
• the screws are tightened all the way.

The gypsum variety consists of glue and lime. To prepare such a mastic, you need to fill the glue with water for 15 hours, after it swells, lime, already diluted in water, is added to the composition. Typically, a steam bath or gas stove is used to obtain a thick consistency. Finally, gypsum is added to the solution. The advantages of this type of glue include the absence of shrinkage after complete drying and antibacterial properties.Therefore, such a composition is recommended to be purchased for premises with a high probability of mold and mildew.

There is a mastic with the addition of sawdust. Such an adhesive solution resembles sour cream in density. To prepare gypsum-sawdust mastic, you need to mix gypsum and sawdust in a ratio of 4: 1 and add glue to the composition (for 1 liter of water, 25 grams of dry composition is needed).

Sulfate-alcohol mixture involves mixing water and vinasse in a ratio of 4: 1. The consumption of gypsum is determined based on the consistency of the resulting composition. Ready-made gypsum mixes are distinguished by good plasticity and provide additional sound insulation. A positive feature of this composition is its ability to take the shape of the surface, which is especially important in situations where it is necessary to level the wall.

Special glue for drywall is produced in cylinders. Usually it is enough for 15 squares of area. The application technology involves processing with the composition of the surface along the entire perimeter with further smearing of the plane independently. In this case, strips of glue are made on the base every 30 cm.

The elastic polyurethane compound is produced in cylinders. It is designed for laying gypsum boards and pasting seams. In addition, he showed himself well as an adhesive for gypsum or ceramic tiles. Work with him is performed using a special construction pistol. Sometimes polystyrene fibers are included in the composition of polyurethane glue, which have a beneficial effect on the density.

To make the right choice when buying drywall glue, you should take into account the type of surface you need to work with. More often, specialists have to work with concrete, brick walls. Sometimes in the work you have to deal with penoplex, which insulates surfaces. Gypsum plasterboard is glued to the penoplex using a gypsum composition. Brick walls, aerated concrete, aerated concrete blocks and shell rock suggest the installation of gypsum plasterboard sheets on a gypsum mortar. This option is the most economical and effective, since on average 5 kg of the mixture will be needed per 1 m2.

For concrete foundations with a minimum curvature, it is recommended to stop at one of the following options:

• polyurethane foam;
• gypsum glue;
• cement composition for tiles;
• putty on an acrylic or gypsum base;
• polyurethane adhesive.

To glue drywall sheets to polystyrene foam, acrylic putties and foam glue are suitable. You can glue the gypsum board on a plasterboard surface with almost any type of glue. However, for a small seam between the materials and maximum preservation of the area of ​​the room, it is worth using a silicone compound or liquid nails. You can use silicone sealant or tile adhesives to adhere tiles to drywall in your kitchen or bathroom. If you have to work with window slopes from gypsum plasterboard, most experts advise you to glue the surfaces together with acrylic putty.

Decorative ceiling elements will adhere better to the base if they are glued with liquid nails or synthetic glue (they will allow you to carefully attach the surface of the skirting board or baguette). When choosing glue for work in large rooms, it is important to rationally treat the expense item, therefore, you should opt for mixtures in bags. Many people call gypsum plasterboard "dry plaster", because after the installation of the material, you can immediately start finishing work.

Thanks to modern technical capabilities, products of a huge number of manufacturers for repair work are presented on the shelves of building supermarkets. These products are represented by well-known world brands and domestic firms.

The Knauf company remains in the list of leaders in the production of construction products.Many experts prefer this particular product. The adhesives presented by the company are of excellent quality with a minimum consumption level during the installation of drywall.

The main advantages of German products are:

• guarantee for all types of goods;
• small rock shelf life of mixtures;
• excellent compatibility with gypsum board made by other manufacturers.

The plaster mix of the Volma brand is also in demand. It has the best plasticity characteristics of the material. This series is more affordable than the German Knauf PerlFix products. But the consumption of the adhesive is about the same.

The series of universal adhesives "Titan" is very popular in the Russian construction market. The product has good adhesion. It is compatible with many materials including drywall.

Henkel manufactures a line of Ceresit brand building adhesives. The mixtures are popular in Europe and the Russian market due to their high quality products. For drywall, Ceresit CM 11 glue is used, which is recommended for installation in rooms with high humidity levels.

In order for the drywall sheets to stick better, the surface for installation should be prepared. This process consists of priming and cleaning. Preparing the glue for work (in the case of using gypsum powder compositions) involves diluting and stirring with a drill with a nozzle.

The technology for applying the mixture consists in laying the composition in the form of small cakes over the surface of the sheet at a distance of 20 cm. You can distribute the composition directly onto the work surface. Then the gypsum board is applied to the wall and pressed well for high-quality gluing. Leveling the material should be done with a rubber mallet.

To glue the ceiling with plasterboard, it is more convenient to use a dowel for fastening. They will help to hold the material until it dries completely, so that the sheet is glued as efficiently as possible. Drywall is a quality material for creating all kinds of structures, wall and ceiling decoration. However, improper sealing between sheets can lead to cracking. It is important to carry out this work using plaster. The type of composition should be selected depending on how the finishing will be carried out further. After the composition has dried, the surface is completely ready for finishing: the walls are pasted over with wallpaper, painted or decorated in any chosen way.
