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.

The plastic in composite decking boards protects them enough that you do not need to paint them to prevent warping. In fact, painting composite decking voids the warranty of some manufacturers. Painting can also increase maintenance on the deck, as you must paint regularly to keep it looking its best.

An exterior paint job typically lasts between 5 and 10 years, though this can range from 3 to 17 years depending on several factors. The longevity is influenced by the quality of the paint and primer, the quality of the application, the local climate, and the type of surface being painted. For example, paint on wood siding may need to be redone every 3 to 7 years, while painted brick can last up to 17 years. Aluminum siding often needs repainting every 5 years.

You’ll want to avoid excessively hot or humid conditions, so it’s best to apply your stain in late spring to early fall. It's also important to watch the weather forecast and aim for days when there isn’t rain expected for at least three days. For new decks, allow the wood to season beforehand for at least four to eight weeks.
