How to Clean and Stain a Deck | Armonk NY Homes
Testing the Wood
A water test is the easiest way to ensure that the wood can absorb sealer or finish. Sprinkle water on the deck. If it soaks in immediately, the deck can be sealed. If the water beads up or stands on the deck, your deck may not need sealing yet.
When you're certain the deck needs sealer, lightly sand rough spots with a pole sander and 80-grit paper. Be sure to wear a mask so you won't inhale the sawdust.
Applying Deck Cleaner
UV rays penetrate 1/64 inches of wood, which causes graying. Apply a brightener and cleaner to restore the wood's natural beauty.
Deck cleaners help remove dirt, nail stains, algae and mildew. If your deck isn't brand-new, always use a cleaner before applying finish.
Carefully read the manufacturer's directions before using the material, and follow all safety precautions and warnings on the label. Use the water test to make sure the wood can absorb the cleaner. Wear safety goggles, a long-sleeved shirt and pants. Don't wear sandals or open-toed shoes.
