How to Paint Treated Wood for a Deck


Pressure treated lumber is one of the top sellers in back yard decking materials. While it is inexpensive, easy to work with and readily available, it is not the most attractive option. Many home owners prefer to compensate for its lack of beauty with a coat of stain or paint. As with any painting task, more than half of the finished quality lies in the preparation. Some debate ensues over how long to wait before applying paint. The experts at the University School of Engineering recommend waiting until the material is thoroughly dry to the touch.

Things You'll Need

  • Broom
  • Belt sander
  • Roller and extension handle
  • Disposable brush
  • Disposable paint pan liner
  • Masking tape
  • Oil-based primer
  • Semigloss paint

Prepping the Deck

  • Sweep any loose dirt and debris from the surface with a stiff broom. If needed, use a pressure sprayer on a garden hose to remove tougher stains and ground in dirt.

  • Allow the deck to thoroughly dry, and sand any rough areas. A belt sander with an 80- to 100-grit belt will work best.

  • Mask off anything you don't want painted, such as electrical outlets or decorative metal trim, and remove items such as barbecue grills or deck furniture.

Priming the Deck

  • Use a cheap throw-away paint brush to apply a coat of oil-based primer to any corners and areas too tight to reach with a 12-inch roller. Oil-based primers are notoriously difficult to clean, so wear something you truly don't mind destroying.

  • Use a roller and an extension handle with a disposable roller cover and pan liner to roll a coat of oil-based primer on the main surface of the deck.

  • Allow it to dry for at least an hour. Apply a second thin coat to be sure the entire surface is adequately sealed.

Painting the Deck

  • Allow the primer to dry overnight before beginning the paint process. Use exterior semigloss latex or floor paint to paint your deck.

  • Use a brush to cut in around areas to0 small to reach with the 12-inch roller. Apply enough paint to cover well without causing runs or drips in the finish.

  • Roll a coat of paint on the main surface of the deck. Work from the house side toward the yard to avoid painting yourself into a corner. Watch for fallen leaves and debris, and remove them if possible to keep them from adhering to the deck.

  • Allow the paint to dry according the manufacturer's instructions before applying a second coat. Leave the furniture and other items off the deck for 24 hours after the final coat is complete.
