Clean the deck floor using a pressure washer. Start the washer on a low setting and increase pressure slowly, being careful not to damage the surface. Allow the surface to dry before continuing.
Prepare the deck floor by applying a coat of latex primer. Brush on the primer using a 4-inch latex paintbrush. Brush along with the grain and not against it.
Allow the deck floor to dry for two full hours, and then apply latex deck paint in the same manner as you did the primer. Do not walk on the deck floor for at least four hours.
Things You Will Need
- Pressure washer
- 4-inch latex paintbrush
- Latex primer
- Latex deck paint
- Although you may only desire to paint the deck floor, it's recommended that you paint the underside of the deck, as well. If you leave the underside of the deck unpainted, it will allow moisture to affect the surface leading to mold, fungi, mildew, rot and warping.
