Prepare

• 1). Remove as much furniture from the room as possible and cover the rest with drop cloths or plastic sheets. Move it to the middle of the room. Take everything off the walls.
  
  
• 2). Cover the floor with a drop cloth.
  
  
• 3). Tape around the windows, doorways, ceiling and floor moldings with painter's tape.
  
  

Clean

• 1). Wash the wall with trisodium phosphate (TSP), a degreaser and general cleaning solution. Put on rubber gloves and eye protection.
  
  
• 2). Mix 1/4 cup of TSP per 2 gallons water to remove accumulated dirt and grease and insure a clean surface for paint to adhere to.
  
  
• 3). Work in small areas, with a clean cloth, rinsing the cloth as it becomes soiled.
  
  
• 4). Use a sponge and clean water to rinse the wall and allow to dry.
  
  

Prime

• 1). Sand the wall with 100-grit sandpaper. Use a hand sander or sand by hand. Wipe the wall with a tack cloth to remove dust caused by sanding.
  
  
• 2). Prime the wood with a product, like B.I.N. that blocks stains caused by wood resins, sap and knots bleeding through the paint. You can find this at any hardware or home improvement store.
  
  
• 3). Fill deep knots with primer as you go to keep the surface smooth. Use a brush.
  
  
• 4). Allow the primer to dry according to the manufacturer's directions.
  
  

Paint

• 1). Apply the paint with a roller.
  
  
• 2). Allow the paint to dry thoroughly before applying a second coat.
  
  
• 3). Inspect the wall and add another coat if the paint hasn't covered the knotty pine paneling to your satisfaction.
