I stained my deck several years ago with Behr deck stain and never had a peeling problem until the last couple of years. For the past couple years I have had to scrape and sand part of the deck floor and restain and I''ll be damned if it doesn't peel again after 9 months. It's just the deck floor and steps that peel. The railings and spindles do not. Anyone know why the stain on the floor keeps peeling? It's frustrating.
