If moss, mold, and mildew are found on the surface, work is carried out to remove them. The same goes for greasy stains.

Advice! Remove old organic paint from the surface.

If the weather is warm and windy, then the surface needs to be moistened before and after staining. Do not work in rainy weather. It is recommended to work in cloudy weather when the surface is not exposed to direct sunlight. When walls are painted in a room, the optimum temperature is no more than +20 ºС.

The end is at the corners of the room, borders with windows, doors, balconies, etc. A uniform result can be obtained if you avoid repainting the finished surfaces in small areas. The ideal way to work a construction seam is to apply light pressure. It must be remembered that with fluctuations in humidity and temperature in the room, the color and shade may change in places.
