Mechanical method of cleansing the surface from paint

How to clean the walls from paint using a metal brush

This method is quite laborious and leading to the formation of pollution and dust, but in some cases the optimal.

For example, the use of washing will not always give a result if the paint is applied to 5-6 layers to the concrete floor and thirty years ago. Cleaning metal using washing also does not always lead to the final result. Therefore, if we are talking about small surfaces that can be cleaned independently, then you can use mechanical cleaning. For example, for cleaning metal-a metal brush, a grinder with a brush, for cleaning a concrete floor-a bell with a petal circle or a strip grinder with sandpaper No. 40-80, for cleaning walls-a drill with a brush with a brush.
