Q: Why & What do we use to sand the walls before every Interior Paint job?

A: We sand all the walls before painting because it removes any kind of dirt, debris, dust and any other trash that might be in the previous paint job or on the surface of the walls.  It also helps when we use sheetrock mudd to fix imperfections on the walls to sand and make the spots smooth.  For this we use a Sheetrock Sanding machine.  This machine is also hooked to a vacuum so that when the sander knocks down the sheetrock mudd spots and all the trash is vacuumed up into this machine instead of going all over the place.
