Can I use a pressure washer on my deck? Yes, you can use a pressure washer on your deck to remove dirt, mold, and mildew efficiently. However, it’s crucial to use the correct pressure settings and techniques to avoid damaging the wood or composite materials.
How to Pressure Wash a Deck Safely?
Using a pressure washer on your deck can be an effective way to clean it, but you need to follow the correct steps to ensure you don’t cause any damage.
-
Choose the Right Pressure Washer: Select a washer with a pressure of 500 to 600 psi for soft woods like pine or cedar. For harder woods, you can go up to 1200 psi. Always start with a lower pressure setting and increase if necessary.
-
Select the Proper Nozzle: Use a fan tip nozzle, generally a 40-degree nozzle, to spread the water over a wider area. This helps prevent gouging the wood.
-
Test a Small Area First: Before you start, test your pressure washer on a small, inconspicuous area of the deck to ensure it won’t cause damage.
-
Maintain a Safe Distance: Keep the nozzle about 12 to 24 inches away from the deck surface. Moving too close can damage the wood.
-
Move with the Grain: Always wash with the grain of the wood to prevent streaks and damage.
-
Keep Moving: Avoid holding the nozzle in one spot for too long to prevent gouging the wood.
