How many PSI does it take to strip a deck?

As mentioned in previous articles, the pressure you need to wash your deck surface is rarely more than 1,500 pounds per square inch (PSI). This is still enough pressure to do damage to soft wood, and enough pressure to leave lap marks on most composite decking. Remember: less is more when it comes to pressure washing.

Likewise, what PSI should a wood deck be?

For tougher jobs, you'll need an even higher pressure. Keep in mind that very high-pressure approaching 3000 psi and more could damage the wood.
