Stucco ceiling is the most important part of its design. As a result of quality work, the ceilings become monolithic and perfectly even, there are no hints of seams on them. In this case, the general view of the room will be impeccable.
Stucco is a building material with high plasticity, and work technologies allow you to create very diverse and complex design projects. This material is environmentally friendly and practical to use.
Ceiling plaster is used in almost any of its features and conditions, since this technology allows even surfaces with large defects to be leveled. Well plastered ceilings can last quite a long time - more than 25 years. The technology of plastering itself is simple, but very laborious, requires a lot of time and effort.
Getting started, the ceiling must first be cleaned from the previous coating. Then carry out the primer with deep penetration compositions.
After this, it is necessary to mark the ceiling. A horizontal line is drawn around the perimeter of the room (using a level or level), the lowest point on the ceiling is determined, 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 you need to subtract 10 mm and move the horizontal line on the wall up to this distance. This line will be the line of the future ceiling.
Plastering the ceiling with your own hands is carried out using various methods and techniques, the choice of which is determined by the tasks of design. For various design solutions, you can use a combination of different work technologies.
It is better to apply plaster using beacons. They are set flush with the horizontal on the wall through 170-180 cm.
Before plastering, to improve the adhesion of the mortar to the ceiling, it is abundantly moistened with water. Plastering ceilings is carried out by applying layers that slightly extend beyond the beacons, the excess solution is removed as a 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 quite uneven (differences reach one and a half to two centimeters), then it is necessary to first reinforce it. It is performed using a metal mesh with a cell of 1 centimeter. The mesh is fastened using mounting stands. It cannot be stuffed onto the ceiling surface. It is necessary that the grid is inside the layer of plaster. When using mounting stands, you can ensure that its weight will not make the finish heavier. Instead of a mesh, polypropylene fiber can be used. It is added to the solution during kneading.
Please note that if the mixture you are going to use is based on alabaster, it is unsuitable for work on concrete surfaces. Chemical reactions take place between alabaster and concrete, which will eventually lead to the fact that the plaster begins to fall off in whole fragments.
Plastering the ceiling can be fine and draft. When roughing is carried out by such material as lime-cement mortar. In this case, minor irregularities and deviations are acceptable. The clean version involves working with white building mixtures . With such work, as a result, the ceiling should be perfectly flat, without the slightest cracks and drops. Checking the evenness of surfaces is carried out using a building level.
Ceiling plastering is carried out mainly using cement-lime mortar (more suitable for roughing, requires experience and is not flexible enough) and a gypsum mixture (the most popular is Rotband, this material is flexible, light, and absorbs moisture well).
