An alternative method is the use of Ushm (grinders), equipped with a diamond disk. When using it on the walls, notches are first made, after which the layer of material is grinding. The tool during operation must be kept so that the disk is located parallel to the surface that is processed. This method is the fastest and most effective, however, during the work, a fairly large amount of dust is formed. Therefore, you should use personal protective equipment — respirator and glasses. They will protect the eyes and breathing organs from dust irritation. Also, during work, from time to time, you need to take breaks and ventilate the room to remove most of the dust.
