Competent plastering walls and ceiling

by USAInvest

Purving walls and ceiling decoration and alignment of walls today, like many years ago, use gypsum plaster. It is very easy to work with it, but some rules should be observed that directly affect the quality of the final result. Before starting work, the room should be prepared. It must be completed “wet” work. Also, wiring and other communications should already be carried out. Cover the camshafts should be covered with plugs. These procedures will relieve excess contamination and simplify work.

The base covered with plaster should be even and not have untouched elements. If this is not provided, the plaster can be exfoliated. If there are fresh brick laying fragments of the solution on fresh brickwork, it is necessary to remove them.

Then the old plaster is knocked down from the walls. True, if it holds well, then you can do only the removal of its fragments. Then it will be possible not to cover the entire surface with new plaster, and only partially apply it. To align the old layer and new, use gypsum putty.

The basis on which it is planned to apply plaster should be treated with a primer. If the base is smooth, then the composition for the primer should make it rough. Thus, adhesion will increase.

External corners are weaknesses of any room, since they very quickly lose their appearance due to constant mechanical loads. To prevent this unpleasant process, you can plant perforated corners on a solution.

If during work there are joints of different materials, then a fiberglass grid is mandatory. This action will prevent the appearance of cracks and provide better adhesion.

Should start with the ceiling. At the same time, light solutions are used. The thickness of the layer should not exceed fifteen millimeters. When the plaster partially hardens, it must be filled with a spatula. Before the plaster layer finally grabs, it must be treated with a damp sponge. After that, the spatula again, more thoroughly, smoothes the layer. The walls are plastered according to exactly the same principle, but in this case it is necessary to use heavier solutions, and the thickness of the layer can reach twenty -five millimeters.

When the work is completed, you need to tightly block the room for a day. This will help to avoid too quickly drying the plaster and the formation of small cracks. The temperature in the room should be in the range from five to twenty -five degrees of heat Celsius. On the second day, the room should be opened and weak ventilation in it.
