Plan on 24 to 48 dry hours after pressure washing before you stain a deck, longer in shade, cool or humid weather. Confirm with a water drop test or moisture meter.
How Long After a Concrete Pour Can You Walk on It?
Light foot traffic is usually fine 24 to 48 hours after a concrete pour in mild weather, cars about 7 days, heavy trucks 28. Cold nights stretch every wait.
How Long After Sealing a Driveway Can You Park on It?
