Surface preparation
The plastered surface must be cleaned with a metal brush and make notches. If the plaster is firmly kept, then the cracks should be laid out to their entire depth, and shake small cracks by 5-10 mm. Когда отслоившуюся штукатурку отбили и поверхность подготовили, приступают к удалению набела, который образуют слои известковой или клеевой краски. Do not clean the embarrassment until the beat, as this work will be superfluous — you need to clean only easily deleted areas.
