After a deck has been power washed it will have some retained moisture within the wood. It’s important to let the wood dry thoroughly so none of the water that soaked into the wood gets trapped under the stain. In perfect drying conditions, 48 hours is enough for the wood to get to where it needs to be before staining.
How do I know if my deck is dry enough to stain?
One way to clear way to check if the deck is dry enough for staining is by using a moisture meter. A moisture meter measures the amount of moisture within the wood itself. When using a moisture meter to inspect your deck lumber be sure to check in several spots along the board.

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 powerwash your deck?
Wood decks are especially vulnerable to power washing, because the pressure exerted by the power washer can lead to splintering. If there is any area on the deck where the wood is already beginning to split apart, power washing it will exacerbate the problem and cause the split area to expand.

Make sure the wood has dropped all of the excess moisture before trying to apply stain. Test to make sure that water is absorbed by the wood which ensures this drying process is done.
How long does it take wood to dry after pressure washing?
The deck will need a minimum of 48 hours to dry after the cleaning. If it rains, wait two more days for the wood to dry. Avoid staining in high heat, high humidity and in direct sunlight.
What if it rains after I stain my deck?

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.
Does pressure washing damage pressure treated wood?
Should You Pressure-Wash It? Yes. Decks made from South American hardwoods such as Ipe, Camaru, and Tigerwood will hold up to the power just fine. Decks made of pressure-treated wood are generally okay, too, assuming you don’t hold the nozzle too close.
