Ceiling Plaster

Ceiling plaster is the most important partits 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 highplasticity, and the technology of work allows you to create a very diverse and complex design projects. This material is clean and environmentally friendly.

Plaster of the ceiling is used practically atany of its features and states, 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 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 that it is necessary to make the markupthe ceiling. 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 move the horizontal line on the wall upwards by this distance. This line will be the line of the future ceiling.

Plaster of the ceiling with their own hands is carried out withusing various methods and techniques, the choice of which is determined by the tasks of design. 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 adhesionsolution with a 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 (swingsreach 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 aregoing to use, 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 operation 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.

Ceiling plaster is carried out mainly withusing 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, absorbs moisture well).
