Гипсокартон — очень удобный материал для wall coverings, widely used in construction. A room covered with plasterboard cannot be called finished. Even a cursory inspection of the walls will reveal seams, small irregularities, and depressions caused by screwing in screws. This means that before further decorative finishing, you will need to find out how to putty plasterboard walls to eliminate all the indentations and roughness.

Scheme of plasterboard putty for varioustypes of edges. The first thing you need to do is choose a putty. The range of any hardware store can baffle an inexperienced repairman. What is better to take: liquid or dry putty, for finishing or for filling cracks? Beginners are advised to take dry mixes, as they have a long shelf life, and even after some time you can use undiluted remains. There are three main types of putty in stores: gypsum, polymer and cement. You can putty plasterboard walls with any of the three. It is important to note that polymer putty is considered universal, suitable for any conditions. Whereas gypsum is not recommended for use in rooms with high humidity and steam generation, such as a kitchen, bathroom, pool. If the walls of a wooden house are covered with plasterboard, then fireproof putty will come in handy. But resistance to low temperatures for finishing work indoors is unlikely to be a determining parameter. The easiest option for a beginner is to buy a universal dry mix. Return to contents</a>
How to prepare plasterboard for applying putty?
The second question is preparing drywall for applying putty.
Scheme of plasterboard joint filling.The main point is to remove any noticeable irregularities. For example, if the screw heads are too recessed, tighten them manually until they are flush with the surface of the sheet. If they protrude, tighten them tighter. After that, check the joints for peeling of the paper from the plaster. If a small piece has come off, carefully lift it with your hand and cut it off at the root with a knife. Sand this area. This procedure is necessary to prevent the putty from peeling off along with the paper later. Are you planning to paint the walls? The preparation technology is similar to that described above. The seams and recesses are filled with putty, the surface of the sheet is primed, and then paint is applied. Do not allow the plasterboard to be saturated with paint to the inner layer. This will lead to bubbles and deformation. So, the joints have been checked, the screws have been tightened. But it is too early to fill the plasterboard walls. First, they need to be primed. Ideally, dry mixtures that require dissolution in water are used. They are applied in an even thin layer over the entire surface of the sheet. To avoid deformation, only the top, cardboard layer is impregnated with primer. Such impregnation will create a moisture-proof layer through which neither paint nor wallpaper glue will penetrate. The primer can be applied with a regular roller - you will get an even layer up to 3 mm thick. Return to contents</a>
Puttying the walls with your own hands
Tools for wall puttying.After waiting for the time required for the primer to dry, you can begin the process. Seal the joints and corners with a special self-adhesive tape. Do this carefully so that the seam runs along the center of the tape. Dilute a small amount of putty in a bucket or basin (do not prepare a large amount of the mixture at once: the putty dries quickly). It is not advisable to dilute the dried mixture with water, as it will change its structure. Select the amount of putty based on 30 minutes of work. Putty the screw crosswise, lengthwise and crosswise, for the best coverage of the screw head. It is better to putty the corners in two steps: first one side, and after drying - the other. This way the seam will be smoother and without drips. Slopes of doors, windows, arches are fixed with an aluminum or plastic corner. Only after this is the putty applied. After drying, smooth out all the uneven areas with sandpaper. Having completed all these steps, proceed to the final, finishing stage of wall puttying. Both the already used type of putty and fiberglass will do here. Dilute the putty to the consistency of thick sour cream, apply it over the entire surface of the drywall with a wide spatula. The layer must be thin and even. After waiting for the wall to dry completely, prime it again. As you can see, puttying drywall walls is not that difficult. But the result will please you. Drywall sheets processed in this way are easy to decorate, and in the future it will not be difficult to remove the coating if you want to change the interior. That's all the work done. Now you know how to putty drywall walls with your own hands.
