We plaster the walls ourselves

What is plaster

The history of plaster is the history of mankind. Since people began to build houses for themselves, plaster also appeared. Even well-placed walls do not keep warm as well as plaster. At first, these were the most readily available materials: clay and straw. But with the development of technology, the quality of plaster mixes has also developed. With the development of geology, gypsum-based mixtures appeared. With the development of chemistry – cement mixtures.

The modern construction market offers a large number of plaster mixes, different in quality, application and properties. The use in the production of mixtures of mineral and chemical additives further expands the range.

What is plaster? Plaster is an Italian word for gypsum, lime, alabaster. That is, those ingredients that actually form the basis of plaster mixes. The word plaster itself is explained as “a hardened finishing layer formed by a building (plaster) mortar on the surfaces of structural elements and parts of buildings and structures.”

So, how to apply this “hardened finishing layer” correctly?

Getting started

We need to start by cleaning the walls. From concrete floors, and these are window and door lintels, the old plaster must be knocked off. Previously, no primers were used during construction. And cement-sand plaster has very poor adhesion (adhesion) to concrete.

Apartment decoration

In panel houses, all load-bearing walls are concrete. Therefore, all the old plaster is knocked off on these walls. It is also necessary to pay attention to the places where the wall panels adjoin to the outer wall. These joints are usually empty and plastered only on top. Such places are best foamed before plastering..

On gypsum and brick walls, you can also knock down all the plaster for safety. But you can also knock it down in areas where it falls off. To check the strength of the old plaster, you can tap it with a hammer. In problem areas, the plaster will ring. And where she holds well, the sound will be dull.

We cover all walls with deep penetration soil in order to create a protective film. If this is not done, then the walls will draw water from the plaster. And it will dry before it gains its strength.

Concrete surfaces are covered with Betokontakt primer.

Primers for walls

Plaster mesh is attached to them.

Plaster mesh

After all surfaces are primed, beacons are placed along a plumb line.

Wall priming

“Skis” are stuffed on the beacons. “Skis” are guiding strips from the plaster mixture that will subsequently cover the walls.

If angles of ninety degrees are not required, then beacons are first set along the edges of the wall. Then a thread is pulled between the beacons and beacons are set along the entire length of the wall at the level of this thread. The distance between the beacons is slightly less than the length of the rule. The optimal distance is one and a half meters.

Which primer to choose

The maximum layer of plaster application is three centimeters. But if you need to apply a larger layer, it is applied in several stages. Be sure to let the previous layer dry.

DIY repair

It is allowed, to strengthen a large layer, the use of drywall. It is attached to the wall with dowel-nails, which creates additional reinforcement of the plaster layer. The “Volma” plaster mix has very good adhesion (adhesion). But for greater strength, in problem areas, such as brickwork, it is necessary to strengthen the plaster with a mesh.

Do it yourself

The mesh is laid on the wall and fixed to it with a plaster mixture. After the first layer dries, apply the main layer. Volma plaster mix is ​​applied to the wall with a spatula.

Repair tips

The plaster is leveled according to the “ski” rule.

Help in apartment renovation

Plastering walls with a cement-sand mixture has its own characteristics. The cement-sand mixture is used in “damp” rooms such as a toilet, bath, shower, sauna. The use of a cement-sand mixture in these rooms is due to the fact that it is able to “breathe” and therefore condensate moisture does not accumulate in the plaster layer.

In order for the mixture to hold on to the wall more firmly, it is reinforced with a metal mesh.

Smooth walls

The cement-sand mixture is rubbed into the mesh with a grater.

Simple tips for decorating an apartment

After the first layer dries, “skis” are rubbed on it.
