Any repair work begins with an inspection of the building, identification of weak areas, necessary changes and surface preparation. The scale of the transformation depends on the condition of the old finish and supporting structures.
Finishing work is performed at the final stage. The specific list of actions depends on the type of external finishing (“wet facade”, ventilated facade systems) and the type of material for supporting structures (blocks, panels, brick, etc.).
Cosmetic alteration of “wet facades”
Painting and plastering walls are the most common types of decorative finishing. Cosmetic work using the “wet” technology includes:
Preparation. It is necessary to inspect the area where they will work, determine the scope of work, the amount of materials, and draw up an estimate. Before dismantling the old coating, fence off the surrounding area, as required by safety regulations. It is also necessary to cover window and door openings with film, protecting the structures from damage.
Inspection of the roof, performance of minor repairs. Often the cause of damage to the paint or plaster layer is a defect in the roof elements, drainage system. Therefore, it is possible to restore the decorative coating only after inspecting the roof and eliminating its defects.
Cleaning the facade. It is necessary to remove the old coating. Sometimes it is enough to remove it only in the damaged areas, but most often it is necessary to treat the surface completely so that there is no peeling plaster or unreliable pieces of coating left. At the same time, crumbling pieces of wall material are removed, if any. Depending on the condition of the structure, it may be necessary to wash the masonry.
Plastering. The main goal is rough leveling of the surface, on which there are no pits and irregularities. For better fixation of the plaster layer, to increase reliability, use a reinforcing mesh.
Plastering is carried out only at positive temperatures, in dry weather.
Putty. Application of the composition gives smoothness to the surface, facilitates plastering and painting.
Priming. The composition increases the level of adhesion, improving the adhesion of finishing materials to the rough plaster layer. Using a primer helps to reduce paint consumption. The type of primer is selected taking into account the type of paint and varnish materials that will be used for finishing.
Painting. For exterior finishing, paints resistant to moisture, ultraviolet radiation, and temperature changes are selected. The paint is applied in two or three layers. Each layer must dry completely before a new one can be applied.
Installation of additional decorative and functional elements. When carrying out cosmetic transformations, worn cornices, ebbs, drainpipes are replaced, decorative elements (for example, shutters) are installed.
At the final stage, the adjacent territory is cleaned and construction waste is removed.
