Plasterboard for wall decoration in modernconstruction is one of the most popular materials. This is due to its low cost, as well as the fact that using this material, you can achieve a smooth surface in a short time. But at the same time, many people have a question about what to use for finishing. Drywall sheets have a smooth and even surface, but joints and screws require additional finishing. And in this regard, the right decision would be to plaster the drywall yourself.
Plastering of gypsum boards is done for the purpose of leveling joints and screws of gypsum boards.
Tools and materials
To plaster drywall you will need the following tools and materials:
- plastering or putty mixes;
- small spatula;
- sandpaper.
When finishing, special attention should be paid not only to the joints of the material, but also to the heads of the screws. They must be covered during the plastering process, for this purpose a special tape is used.

Removing surface irregularities
Before plastering walls fromplasterboard, it is necessary to repair dents and potholes that may form during improper storage or transportation, defects made during installation. To do this, the surface must be primed, then apply a layer of putty, and only then - a thin layer of plaster. But it is important to remember that the putty layer should be a maximum of 3 mm. If the dents are very large, then plastering is mandatory.
Scheme of priming walls.When the plasterboard surface has significant defects, it is not recommended to apply a thick layer of plaster on them. Of course, this will hide the flaws for some time, but then the sheets may not withstand the weight of the plaster and will begin to deform and crack. In this regard, if large defects were found during the installation of plasterboard with your own hands, it is better to immediately replace the damaged material with high-quality one. But that's not all. Before plastering a plasterboard wall, you need to observe all the small nuances. The screws must be well recessed, as they also create unevenness. When installing sheets, the joints between the material are not entirely smooth. If curved elements were created, a needle roller was used, and it can leave indentations behind. Therefore, all these minor defects must be eliminated. When preparing the surface for plastering, it is necessary to follow a number of sequential steps:

Plaster surface: recommendations
So, the surface is completely prepared, andyou can plaster a wall made of plasterboard. The plaster should be applied in sequence. Plastering plasterboard does not require the use of beacons, which makes the work easier. plastering plasterboard with your own hands is a very responsible job, since any bump or unevenness will be visible and cannot be hidden. Using a spatula, collect the plaster solution and place it on the trowel, then press it at an angle to the surface. The movements should be slow, and as for the direction, you can choose any, but the main thing to consider is that the layer should be very thin. If necessary, you can repeat the trowel.
Methods of applying plaster.The next batch of mortar should be applied without an interval and tightly joined with the first. It is important not to forget that the less mortar is taken, the smaller the strokes, which means that the plastered surface will look more beautiful. After applying the first layer, it should dry. And only then can you proceed to finishing. When laying the second layer, all the same tools are used. It is also necessary to take into account the fact that the more strokes are made with an overlap, the darker the surface will be, but if it is possible to cover the underlying strokes and the gaps between them, the surface will acquire a lighter color. Thus, you can give the walls interesting patterns, playing with halftones. When plastering drywall with your own hands, the trowel can be replaced with a textured roller. By applying the solution with a roller, you can get not only an even coating, but also a relief pattern. But you can use a roller when applying plaster to gypsum board only at the very beginning of the finishing. When working with this tool, the textured nozzle is rolled directly over the composition, which must be poured into a small tray and applied with movements from the bottom up. When working with a trowel, after applying the solution, the surface is processed with a trowel, and when using a roller, the walls do not need to be smoothed, since such finishing is final. If frescoes are provided, then the plaster should be applied only with a trowel. From the above, we can conclude that only by following a strict sequence, you can achieve a smooth and high-quality surface when plastering drywall with your own hands. Also, do not forget that drywall should be purchased only moisture-resistant, otherwise it can deform from moisture. Do not apply a thick layer of plaster, otherwise all the work will go down the drain. The use of decorative plaster is also possible. In this regard, in order for the house to be beautiful and cozy, you can experiment without fear when decorating the walls.</ ul>
