I have a pressure treated pine fence which I am going to powerwash and then seal.

(board-on-board with 1 inch thick boards and 4 x 4 posts. 12 yo. never been stained or sealed)

After powerwash, how long should I wait for it to dry before seal? Usually it's 1 or 2 dry days, but with all this daily rain we've had for weeks, it never gets a chance to dry. And even if it doesn't rain one day, it's sitting on soaking wet ground.

How many "consecutive days of dry weather" should get it "thoroughly dry enough" to seal after powerwash?

Thanks for your help.
