Preparing the Walls

• 1). Lay a tarp or an old sheet over the flooring.
  
  
• 2). Seal the grooves typically found on wood paneling with wood putty or plastic wood. Use a putty knife and remove the excess as you apply the putty. Sand with sandpaper to smooth any rough spots once the putty dries.
  
  
• 3). Wash the walls using a rag or a sponge mop and a bucket filled with water. Use a household cleaner to remove any grime or dust from the walls.
