Short product review here for Behr’s DeckOver. This is a two coat application good for older decks with some minor imperfections. It’s a brush and roll application. 1/2inch nap roller. We power wash and sand as needed prep wise. Do not skip out on your prep work. Overall I love this product, I’ve done about 5-6 decks now with it over a 2-3 year span. They have all held up extremely well.
