DIY is possible but presents risks of uneven surfaces or improper adhesion; professionals offer expertise to ensure a lasting finish.

Beyond liquid rubber, homeowners can use sealants, stains, membranes, or tapes as waterproofing options. Oil-based or water-based sealants soak into the wood, creating a moisture-resistant barrier. Waterproofing stains—available in transparent, semi-transparent, and solid colors—add both protection and style to your deck. For heavy-duty waterproofing, deck membranes and waterproof tapes can be applied under the deck boards to direct water away from the structure below. Whatever method you choose, clean and prep the deck first to ensure the best, longest-lasting results.

To make sure the paint won’t bubble as you apply it, make sure to paint on a day that’s cooler than 85 degrees Fahrenheit. When the temperature is too high, the paint won’t dry evenly, which can result in bubbles forming on the surface. Another way to prevent paint from bubbling is to clean the walls, apply primer, and let everything dry completely before you begin.

It’s best to use an exterior latex acrylic paint to promote maximum adhesion to composite decking. This flexible paint type can better cope with the natural expansion and contraction that can occur with composite deck boards. Oil-based paints won’t adhere as effectively and are more likely to crack and peel as the boards flex. Testing whether your chosen paint will stick on an inconspicuous section or a spare board is a good idea.
