What are the steps and what materials do I need?
You will need:
a good six or four inch putty knife patching compound (standard wallboard joint compound for walls) A mudd tray or a clean flat board with a straight edge
Patch dings, gouges and dents by scooping a small amount of compound onto the putty knife. Place the knife on the wall at about 45 degrees and about 4 or 5 inches from the damaged area. Pull the knife across the damaged area with a steady pressure. Scrape the excess compound off the knife by pulling it across the edge of a board or mudd tray. Make two more passes across the area, removing the excess from the knife after each pass. Let the patch dry.
depends what the wall is made out of. A simple way is to hang a picture over it.
get mud and whipe it on the wall that you need to be fixed. easy one step fixing!
