Question: How To Pressure Wash A Deck

Is it OK to pressure wash a wood deck?

For cleaning a wooden deck, you’ll be best served by using the lowest pressure setting that’s still effective. For soft woods like cedar or pine, this is usually about 500 to 600 psi. For harder woods, it can go up to 1200 to 1500 psi. Never get closer than 12 inches from the deck unless you’re using low pressure.

What do you put on deck before pressure washing?

Applying the Cleaner Apply a wood cleaner formulated for pressure washers using a low-pressure soap nozzle. Apply the detergent from bottom to top. Use a utility brush to scrub the solution in tight corners and between deck balusters. Apply the cleaning solution, covering the width of a few boards with each pass.

Can you ruin a deck by pressure washing?

A pressure washer is a straightforward machine that can clean very well with only water. However, it can ruin your deck if it’s not used properly. If you use it with too much jet pressure or place the tip too close to the surface of your deck, you can deeply etch the wood and cause the fibers to splinter.

Should I use soap to pressure wash deck?

Study How to Pressure Wash a Deck and Begin the Process Most pressure washers come with a soap dispenser mode, so fill it up with a cleaner that will work for your wood. Switch to soap-only mode, and begin to cover any areas with grime. Then, you should use a synthetic scrubbing brush to massage the sprayed areas.

Is it better to sand or power wash a deck?

DO sand your deck before sealing. At that point, lightly sand the surface to remove splintery or fuzzy patches caused by pressure-washing the deck. A pole sander with 80-grit sandpaper will suffice; a power sander is overkill. Then seal the deck to protect from cracking, cupping, and warping.

Why you shouldn’t power wash deck?
