Frequently Asked Questions about Deck and Fence Pressure Washing
How to pressure wash a deck?
Start by clearing the deck of furniture, plants, and debris. Sweep thoroughly to remove loose dirt. Set your pressure washer to a low or medium setting (around 500–1200 PSI) and use a 25- or 40-degree nozzle to avoid damaging the wood. Spray along the grain in smooth, even passes, keeping the nozzle at least 12 inches from the surface. For stubborn dirt or mildew, pre-treat with a wood-safe deck cleaner and let it sit for 10–15 minutes before washing. After cleaning, let the deck dry completely before sealing or staining. Proper technique protects the wood and restores its natural look.
How long after power washing can you paint a deck?
You should wait at least 48 hours, but ideally 72 hours or more, after power washing before painting a deck. The wood must be completely dry to ensure proper paint adhesion and to avoid peeling or blistering. Drying time can vary based on weather, humidity, and how much water was absorbed during washing. To be safe, do a moisture test by taping a plastic sheet to the deck – if no condensation forms underneath after a few hours, it’s dry enough to paint. Patience here pays off with a long-lasting, even finish.
How to get rid of green algae on wood?
Start by gently scrubbing the affected area with a soft-bristle brush and a mix of water and dish soap to loosen the algae. For tougher buildup, apply a solution of 1 part white vinegar to 3 parts water – or use a wood-safe commercial algae remover. Let it sit for 10–15 minutes, then scrub and rinse thoroughly with a garden hose or a pressure washer on a low setting (to avoid damaging the wood). Allow the surface to dry completely. To prevent regrowth, keep the area dry, clear of debris, and consider applying a sealant or anti-algae treatment.
What happens if you paint over algae?
Painting over algae will not allow the paint to adhere well, and the algae can continue to grow underneath the paint, causing it to blister, peel, or flake off. Because algae retains moisture, it will also eventually lead to mold, mildew, and damage to the painted surface. For a long-lasting, clean finish, it is important to remove the algae completely before painting by scrubbing with a cleaner, using a pressure washer, or applying a fungicidal wash, then allowing the surface to dry completely.
How to restore a wooden fence?
Start by inspecting the fence for damage – replace or repair any broken boards, loose nails, or rotted sections. Clean the surface thoroughly using a pressure washer on a low setting or scrub with a mix of water and wood-safe cleaner to remove dirt, mildew, and old stain. Let the fence dry completely, usually 48–72 hours. Sand any rough spots or peeling paint to smooth the surface. Then apply a high-quality wood stain or paint using a brush, roller, or sprayer. Sealing the wood helps protect it from moisture, UV damage, and aging – restoring both appearance and durability.
