id like to know if this product would cover older paint on a deck

We used it to re-stain our deck and it covered the old stain smoothly. Very pleased with the outcome

Thank you for your interest in Cabot. Cabot Solid Color Acrylic Deck Stain would be a great choice for use on your deck. To prep the surface, we recommend sanding and scraping to remove peeling paint, loose wood fiber, etc. The deck should then be cleaned with Cabot Problem-Solver® Wood Cleaner. These are general, basic recommendations. For additional info, please contact our Consumer Relations Team directly at 1-877-825-7727 at your earliest convenience as they are standing by to assist you.
