Note: If possible, position new deck boards with the crown facing up so water will run off. For this reason, be selective in purchasing so you have a good recognizable crown side. Examining the end of the board will reveal the crown.

The pool railing sections as well as the outside railings and benches were given fresh protective coatings using Superdeck Transparent Stain. The stain is a high-solids, professional-grade wood finish. The stain uses high-quality pigments to inhibit damage caused by the sun, a three-oil system to provide superior protection, and a highly effective mildewcide to inhibit mildew growth on the coating surface.

When rolling, use a 3/8-in. nap synthetic roller cover for smooth surfaces, use a 1/2- to 3/4-in. nap for medium texture, and a 1-1/4-in. nap for a heavily textured finish.
