How to Paint Over a Mural
- 1). Begin your preparations by removing the furniture from the room or at least moving it into the center so that you have room to work. Lay down drop cloths to protect your floors.
- 2). Using a sponge mop, wash the wall with a mixture of TSP and warm water. This will get rid of any dirt or oils that might be on the wall.
- 3). After the wall has dried, give the entire wall a light sanding with the 120-grit sandpaper, then remove any sanding dust using your sponge mop and clear water.
- 4). Apply a coat of latex primer to the entire wall and allow it to dry thoroughly, then apply a second coat of primer and allow time for it to dry thoroughly.
- 5). Finish painting over and covering up your old wall mural by applying two coats of your new paint color. The two coats of primer in combination with two coats of paint should prevent any "burn through" of the old mural.
