Use an orbital sander to remove any gloss and smooth out any rough areas on decking boards, railings or stair treads. Always be sure to wear a dust mask and eye goggles to protect your eyes when sanding treated wood.

2
THOROUGHLY VACUUM THE DECK, AND THEN APPLY SEALANT

Thoroughly vacuum the deck, then apply staining sealer to all deck wood with a pressure sprayer or paint roller. Treat the understructure first, then exposed surfaces.

SPRAY OR ROLL ON THE SEALER OR STAIN
