Deck Preservation
Question: I have heard a lot of different opinions on what I should use on my wooden deck to preserve and seal it. First I heard use Thompson's Water Seal then I heard "Oh no...... never use that crap." Please help me. Background info: I live in Piedmont area of North Carolina, the deck is about 15 years old, make of Southern White Pine. About 5 years ago I used a Behr Semi-gloss stain on the deck.
Answer: The Behr product is a urethane based product and should have sealed the deck. I like the Thompson's Water Seal but not over urethane based products. If you want to reseal I would use clear a urethane based sealing product. Make sure the deck is really clean before application.
