Not Always Cut-and-Dried. For the best results, wait to paint your new deck until the moisture level is down to 15 percent. Depending how long the wood sat at the lumber yard before you purchased it, it could be ready to paint the day you finish your deck, or it might require between four and 60 days of drying. You can rent a moisture meter from your local hardware store to get an accurate read.
