Methods of wall texturing include applying drywall mud with a roller, notched trowel or machine. Some paint manufacturers offer a line of paint that includes texture so the application of the texture occurs at the same time as painting the room. Each technique produces a different texture on the walls.
Drywall texture gives a more aesthetically pleasing look to the wall than leaving it flat. The texture also helps cover imperfections in finishing the drywall. Applying joint compound with a sponge creates a faux stucco finish, while use of the notched trowel creates a basketweave pattern. Machine texturing uses compressed air and a special spray gun that rapidly applies the compound in a variety of textures.
