Here's the deal with leaving used rags covered in oil-based stain lying around in a pile: Depending on the conditions, these rags can take just an hour or up to a few days to combust. The source of ignition is caused by trapped heat that can be compounded if the rags are near a heat source.

Yes, you must thoroughly clean your deck before staining. If you don't, dirt, debris, grease, and mildew can get trapped between the wood and the new stain. This not only looks unsightly but also prevents the stain from penetrating the wood properly, reducing its ability to protect the deck from weather and UV rays. As a result, the stain won't last as long or look as good. Any existing mold or mildew left untreated can continue to grow beneath the new stain, potentially leading to wood rot and structural damage. Always wait at least 48 hours after cleaning for the wood to dry completely before applying stain.

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.

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.
