What to do after plastering walls

Answer to the question thatdo after the plastering of the walls, depends on how you plan to finish the room. Several options are possible: painting, wallpapering, tiling and creating plasterboard structures. In the first three cases, care must be taken to ensure that the material of the finish is securely held on the wall, in the latter, it is only important that the metal profiles under the plasterboard are securely fixed.

Preparation of plastered walls to the

putty. The plaster drying time is not less than 1 month, during this time it is recommended not to touch the walls. How quickly the treatment of walls after plastering can begin, depends on many factors, in particular, on the temperature and humidity level in the room, its ventilation. To accelerate the drying process, it is recommended to provide a through flow of air through the room, opening the windows and doors.

It is important that the temperature does not fall significantly below the room temperature, otherwise there will be difficulties with the evaporation of moisture. Also, it should not exceed the room too much, otherwise it will lead to cracking of the coating.

When choosing what to handle the walls after the plaster, you should stop on the primer. With its help, you can extend the life of the plastered surface, improve its performance, including water resistance. A significant improvement in the adhesion of the material is provided by the fact that the primers impregnate its surface deep enough and strengthen the surface.

Choosing a filler for walls after plastering

While the primer dries, you need to choose what to putty the walls after the plaster, since they need to be leveled before further finishing. To this end, it is better to purchase a starting mix: it is designed specifically for the treatment of walls after plastering, and is suitable for eliminating significant differences in elevation.

Also, when the primer after the plaster on the walls dries, you can treat their surface with a universal or finishing putty. The latter, compared to the starting mixture, have comparatively inferior consumer characteristics, and are usually used in cases where the layer of plaster has no significant flaws.

Based on the material the substrates are divided into three categories:

• cement - resistant to moisture, but have a high degree of shrinkage;
• gypsum - cheap, does not shrink, is malleable when applied, but sensitive to moisture level;
• polymer - expensive, do not shrink, resistant to moisture.

Most often, plaster based gypsum is used however the scope of use is limited, they are not recommended to be applied in very wet rooms where there is contact with water in the bathroom, the pool. Otherwise, why putty the walls after the plaster, if due to high humidity, the coating on the basis of gypsum quickly deteriorates.

It is absolutely forbidden to use gypsum plasters on the street because moisture and frost destroy the mixture of Rodbund and others like that.

In the form of sales, putties are available in two categories:

• ready - already diluted solution, which can be used immediately after opening the container;
• dry - mixtures designed for self-cooking, but having much lower cost than ready-made mixtures.

Thus, the cheapest option is dry gypsum powder, but it also has the lowest quality. Gypsum mixtures are great for sealing cracks in the walls. The most expensive are ready-made fillers based on polymers, these materials are better used for making the finish coat.

Technology for the treatment of plastered walls

Often before the beginning of putty work, the question arises as to whether to remove beacons after plastering, or they can be left in the walls. It is recommended to do this without fail. The material for the manufacture of lighthouses is metal, and if left, they will eventually become corroded. This, in turn, will reduce the strength of the plaster layer, and, ultimately, lead to its crumbling. Cracks and other damage will appear on the surface of the walls.

After the decision is made, whether it is necessary to choose beacons after the plaster, it is possible to proceed to the starting putty of the surface. The lower, most coarse layer of the material is applied. With the help of mixtures for starting putty rub holes and strobes, eliminate large differences in heights. The thickness of one starting layer can sometimes reach 15-20 mm.

Under the layer of putty, you can put a paint net, stretching it over the entire surface of the wall being treated. This will make it possible to achieve a more even laying of the material, improve the strength of the starting layer of putty.

When the starting coat dries, proceed to the finish finish, which is carried out with the use of finishing mixes. Unlike the starting, it is applied very thin layer, so that it completely repeats the resulting relief of the walls. In some cases, the question arises whether it is necessary to putty the walls after plastering with Rothband, so that the surface is perfectly even. If you comply with the technology, the need to apply additional finishing layers disappears, the walls and so are obtained aligned.

Preparation of walls for painting or wallpapering

After finishing puttying work, you should wait for the complete drying of the walls, and only then prepare them for painting or pasting with wallpaper. The technology for performing both types of finishing is the same, the difference is only in the nuances in choosing the finishing materials. The choice of a suitable method of finishing can take as much time as drying the walls after the plaster - about a month.

So, after drying the primer, the walls are primed for painting using a special primer, sometimes after preliminary sanding. If you plan to glue the wallpaper, then, instead of the primer, the walls after drying can be covered with wallpaper glue. In this case, water is added to it more than usual. In addition, the adhesive should be recommended by the manufacturer for use in this capacity, otherwise it is better to apply a standard primer mixture to the walls.

Errors in the execution of plastering and priming work on the walls of

The disadvantage is the abandonment of metal beacons in the plaster. They eventually oxidize, which leads to cracking of the coating, even if it is carefully coated with a primer. If, due to the corrosion of the beacons, cracks appear on the wall after the plaster, then it is almost impossible to fix this with additional puttying, because the cause of the problem will remain.

Also the appearance of cracks is a sign of haste in work. Instead of performing plastering in several layers, the coating is made single-layered and coarse. Under the action of gravity the solution slides to the base of the walls, begins to harden and crack. To avoid this, the plastering of the walls must be carried out in several stages, you can not immediately apply a huge mass of material.

When starting priming and filling the surface, it is necessary to take into account the drying time of the walls after plastering. Premature start of work is a violation of technology, and will lead to destruction of the finish after drying. To correct this error without repeated repair is impossible.

If the wall cracked after plastering and even changed its geometry, this indicates the lack of professionalism of the masters who performed the plastering, not having made sure of the correct application of the material. At the same time, if the wall turned out smooth from the first time, then before painting or pasting wallpaper, it would not even require shpaklevanie.
