How to plaster drywall? Can I plaster drywall? Plastering plasterboard with their own hands

Quite often novice home masters are wondering about what and how to plaster drywall. To begin with, the GCR is also called dry plaster.

Why GCR is called plaster

First, with the help of sheets of this material, it is possible to level the walls and ceiling, and also to repair the defects of the plane. Secondly, the installation of GCR is not associated with wet work. Third, after installing the sheets, the wall becomes smooth and smooth, which allows you to almost immediately begin finishing work. Some believe that to bring drywall to an ideal smoothness is not necessary. However, the opinions of experts on this issue were divided.

Do I need to plaster

If you also wondered if plasterboard plastered, you need to deal with it in more detail. Some argue that it is not necessary to plaster the sheets - this is a vain business and takes a lot of time and energy. Other masters claim that the plastering process is necessary when the wall was subjected to loads and lost its original appearance.

In general, it is possible to plaster drywall only in the case when it has the qualities of moisture resistance. Application of the composition should be carried out in several approaches, in thin layers, each of which is covered with a primer. To do this, use a deep penetration composition designed for gypsum-containing materials.

Results

Understand the question of whether you need to plaster drywall - a thankless task. Some believe that a thin layer of putty will be enough, while others argue that it is necessary to plaster the surface. If you want to achieve an ideal result, then you should carry out such training, about the features of which will be discussed below.

Additional recommendations on the process of preparation of drywall before applying plaster

If you are thinking about the question of how to plaster drywall wallpaper, you should also know about the features of surface preparation. Due to the fact that the GCR is most often mounted using the method of using screws, grooves and irregularities remain on its surface. Sometimes gypsum cardboard bends during the installation, and sometimes to create curved structures using a needle roller. After such an impact on the canvas remains a huge number of depressions. All these shortcomings before attaching wallpaper are important to eliminate.

The need to use a primer is due to the fact that it is important to increase adhesion between gypsum cardboard and subsequent finishing layers. The primer should be applied to every centimeter of the skin. For this, a foam roller or a wide brush is usually used. Wet the sheet too much is not necessary, because otherwise it can be deformed.

After you figure out the question of whether it is possible to plaster the plasterboard, you should apply a filler that will hide the joints of the sheets and the recessed screws. On top of the layer putty put a ribbon-serpyanka. Wherever the fabrics converge at an angle that may be external or internal, align the flaws with perforated aluminum profiles that overlap the corners covered with the putty.

From surplus of a mix it is necessary to get rid of a method of smoothing a surface of a profile. Once the drywall has dried after applying putty, it should be primed once again in the manner described above. Prepared in this way, the surface can be used not only for gluing wallpapers, but also for pasty mixtures or dry stone crumbs from minerals of different colors.

Advice

If you plan to prepare a drywall before applying the wallpaper, the composition will help to straighten out the problem areas, for example, potholes or dents. This should be done in several approaches, each previous layer should be given time to dry.

If small potholes and dents are to be closed, the surface is covered with a primer at the first stage, and then a layer of putty is applied, a little later - a layer of plaster. It should be remembered that the putty layer should not exceed 3 mm in thickness. If the potholes have a more impressive depth, then plastering can not be avoided.

Before plastering plasterboard, you should familiarize yourself with technology that does not recommend hiding the erection errors of the frame by using a thick layer of plaster. This will remove the surface from the marriage, but eventually the sheets will not be able to hold the applied layer of plaster. This will cause their deformation and the appearance of cracks, as well as exfoliation of the plaster layer. If you have identified rather large curvatures, then it is better to replace the sheets with high-quality material.

Recommendations for plaster application

If you are wondering about how to plaster drywall, you should know that the material is applied to the surface with a thin layer, and pre-ground is primed. If it is a question of granular coatings, then it can be pasty mixtures of factory production, which are already ready for use.

The composition is applied by a sprayer or a trowel, the thickness of the layer will depend on the diameter of the grains. The first parameter should exceed fractionality 1.5-2 times. Stone colored dry powder is sprayed onto the surface, which is pre-lubricated with glue.

Instructions for applying plaster

If you, too, belong to home masters, who faced the question of how to plaster drywall, you should know about the specifics of carrying out such work. Once the sheet assembly has been completed, the surface must be cleaned of the settled dust. This task is perfectly handled by an industrial vacuum cleaner. If it is not available, then you can use improvised means. As them they are rags, which are previously slightly wetted with water.

At the next stage, plastering of joints, seams and unevenness is carried out. Once this layer has dried, the treated areas must be covered with an equalizing layer. Using a primer suitable for gypsum board surfaces, you need to treat it with a base. It is recommended to choose for these manipulations a primer for moisture-resistant plasterboard. Only after that, you can start applying decorative plaster.

These works should be carried out at moderate humidity and temperatures ranging from +5 to +35 ° C. The master should use a respirator or gauze dressing, as well as rubber gloves. After completion of the work, the tool is cleaned, and the rest of the finishing material should be tightly closed and left for storage in a dry room. Sometimes the plaster is used to restore the damaged layer.

Plaster coating of the ceiling before gluing the wallpaper

If you are faced with the question of how to properly plaster drywall, which is installed on the ceiling, it is important to familiarize yourself with the technology. For the reason that the ceiling will have to spend quite a lot of time, and the application of the compounds can not be called a convenient process, you should buy a roller with an extension for the handle. With it, you can work at a height of up to 4 m.

Plastered plasterboard with their own hands in the ceiling, typing mixture with a spatula from the container. The composition should be transferred to the trowel, and then tightly press the tool to the plane at an acute angle with respect to the surface. Plaster will be of higher quality if you use this method, refusing the sprayer. The dense layer can be achieved only with the use of a powerful compressor. It is important that the movements are smooth, the direction can be any, the main requirement here is that the composition is applied in a thin layer.

If necessary, the trowel must be re-applied on the surface. The next batch of plaster is applied without a gap, close to the first portion. The smaller the portions, the smaller the smears, in the end it will achieve a better effect. As soon as the first layer dries, you can proceed to the formation of a finishing layer. It is necessary to carry out these works with a trowel, overlap strokes should be greater if you want to get a darker patch of coverage. Instead of the trowel master sometimes use other tools for the type of texture rollers.

Conclusion

Plasterboard plasterboard is necessary in the case when it is required to hide the defects of installation and cavities from fasteners, as well as joints between the canvases. It should be remembered that the plaster is applied only after priming and plastering the surface. Once all the layers have dried, you can proceed to the final alignment before gluing the wallpaper. It is important to seal the outer corners, which will also be treated with wallpaper.

The solution to the corners is superimposed in the minimum amount. It is important that it is enough only on the plane of the corner. The perforated profile is then applied to the corner and leveled using the building level. If you notice that the corner is fused, the gypsum board structure was not assembled exactly. You can correct the situation by putting more shpaklevki under the metal.
