There’s no single paint that’s the most waterproof. Instead, there are several types of waterproof and water-resistant paints that suit different purposes. Epoxy paint, for instance, is commonly used to provide a waterproof coating to floors and decks. Masonry paint is an excellent choice for exterior walls. Meanwhile, there are waterproof acrylic paints that can be used for interior and exterior walls. It’s more about choosing the best type for what you’re painting instead of the most waterproof paint overall.

Avoid using cleaning products that are abrasive or contain bleach or acidic components on composite decking to avoid discoloration. Early-generation Trex decking isn’t designed to handle pressure washer cleaning—and if you use them on second-generation boards, always use a low setting to avoid the risk of damage that can risk voiding your warranty.

Depending on factors such as weather, use, substrate condition, and type of paint used, pool deck paint should last anywhere from 1 to 5 years. Keeping the paint clean and resealing every year or two can help extend the life of the paint. Proper preparation before painting also plays a large role in how long the paint lasts on a pool deck. Paint will likely not last as long on a pool deck in poor condition before painting.
