I had a Handyman stain my deck. He used just an ordinary Deck Stain he purchased from a local Ace Hardware. I had the deck power washed first and gave it several days to dry. He applied one coat of stain and it did not cover good so he rolled another coat of stain. It has now been two months and it has never dried. Can anyone tell me if there is any product I can now put on top of it that will dry???
