Ceiling Plaster

Plaster ceilings are the most important part of its design. As a result of high-quality work, the ceilings become monolithic and perfectly even, there are no hints on the seams. In this case, the overall appearance of the room will be impeccable.

The building material plaster has a high plasticity, and the technology of the work allows you to create very diverse and complex design projects. This material is clean and environmentally friendly.

Ceiling plaster is used in almost all its features and conditions, since this technology allows even surfaces with large defects to be evened. Well plastered ceilings can last for quite some time - more than 25 years. The technology of plastering itself is simple, but very laborious, it takes a lot of time and effort.

Getting to work, the ceiling must be cleaned beforehand from the previous coating. Then the priming is carried out with the formulations of deep penetration.

After this, it is necessary to make a ceiling marking. Apply a horizontal line around the perimeter of the room (using a level or level), determine the lowest point on the ceiling, measuring the distance from the horizontal to all points of the perimeter of the ceiling, including the corners. At the point where the distance is the smallest, the ceiling is the lowest. From the smallest distance it is necessary to take away 10 mm and to transfer the horizontal line on the wall upwards to this distance. This line will be the line of the future ceiling.

Plaster of the ceiling with their own hands is carried out using various methods and techniques, the choice of which is determined by design objectives. For a variety of design solutions, a combination of different operating techniques can be used.

Apply plaster better using beacons. They are exposed flush with the horizontal on the wall through 170-180 cm.

Before plastering, to improve the adhesion of the solution to the ceiling, it is abundantly moistened with water. Plastered ceilings by applying layers that slightly go beyond the beacons, the excess solution is removed by the rule. If you need to apply a large layer of the mixture, then you need to do this in several stages (each subsequent - after the complete drying of the first).

If the ceiling is rather uneven (the differences reach one and a half to two centimeters), then it is necessary first to make its reinforcement. It is performed using a metal grid with a cell of 1 centimeter. Fastening of a grid is made by means of installation supports. It is impossible to fill it with a ceiling. It is necessary that the mesh is inside the plaster layer. When using mounting stands, you can ensure that its weight will not make the finish too heavy. Instead of a grid, you can use polypropylene fiber. It is added to the solution during batching.

Note that if the mixture you are going to use is based on alabaster, it is not suitable for work on concrete surfaces. Between the alabaster and concrete, chemical reactions take place, which in time will lead to the fact that the plaster will begin to fall off whole fragments.

The plaster of the ceiling is clean and rough. When roughing works are performed with such material as lime-cement mortar. In this case, slight irregularities and deviations are permissible. The clean version assumes the use of building mixtures of white color. With this work, the ceiling should be perfectly flat, without the slightest cracks and swings. Verification of the smoothness of surfaces is carried out using the building level.

The ceiling is mainly plastered using a cement-lime mortar (more suitable for roughing, requires experience and is not sufficiently elastic) and a gypsum mixture (the most popular is Rothband, this material is elastic, lightweight, and absorbs moisture well).
