Today, such material as drywall is very widely used during repairs. This is due to the versatility of application: sheathing pipes in bathrooms, arched opening, decorative plasterboard construction on the ceiling, shelves and niches, as well as all kinds of interior partitions.
Often, drywall sheets are mounted on a pre-assembled frame, consisting of metal profiles or wooden bars. However, laying drywall on glue is a great alternative to the traditional option. This allows you to significantly save time and finances, as well as avoid the loss of usable area due to frame structures. Most often, laying drywall on glue is done in the manufacture of window slopes, as well as for leveling walls. If you glue sheets of drywall in a joint, without seams, then the result is a perfectly flat surface. In the future, you can go through the finishing putty and paint, or lay tiles, glue wallpaper andetc. For installing drywall over a large area, it is better to buy ready-made drywall adhesive from a hardware store. If it is necessary to glue drywall on a small area or several slopes, then such glue can be prepared independently at home.
For this we need: a suitable container, a construction mixer (a nozzle on a puncher is also suitable), starting putty, water, construction PVA glue. Then you need to follow the following instructions and you will be able to prepare drywall glue.
Starting putty is taken and diluted with water in the same way as a regular mortar. If there is no starting putty, then you can replace it with a finish one. The solution is kneaded until it resembles a homogeneous thick mass without clots and lumps. If the solution is very liquid, then during the gluing process it will flow out from under the sheet. If the solution turns out to be too thick, then it will not be very convenient to work with it and it will not be possible to attach the material qualitatively.
Next, PVA is added to the mixture and mixed again. The amount of glue is taken at the rate of 1 kg of glue per 13-15 kg of putty. It takes a few minutes to let the glue brew, and then it can be used to install drywall.
Gypsum board adhesive is applied dotted (diameter approx. 15 cm) on the sheet along the edge and in the middle, and also on the surface of the walls. The weight of a standard drywall sheet is about 30 kg, so it is not recommendeduse a large amount of glue, as it will be quite difficult to work.
After the glue is applied, gently apply the sheet and press lightly. All manipulations should be performed very carefully, since drywall itself is rather fragile and can easily crack. With the help of the building level, horizontals and verticals are controlled. For greater reliability, you can fix the glued drywall in several places with dowels or self-tapping screws. Do-it-yourself drywall adhesive is not inferior in its properties to the factory one.
