Get matched with top deck staining pros in Lakota, ND

If you have wood decking, there are several common deck problems that you might encounter. For example, your natural wood boards may fade over time due to things like sunlight, weather, and debris. On top of that, some types of wood decking can rot, grow mold, and attract destructive pests—including termites, carpenter ants, and woodpeckers.

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.

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.

It is definitely worth sanding a deck to ensure the wood absorbs new stain. Sanding a deck removes the outer layers of aging wood, allowing the stain to penetrate. It also gives a fresh look to the entire surface as part of the deck refinishing process. Without sanding, your stain or sealant is less likely to absorb into the wood. While sanding a deck is a time-intensive project, the rewards are noticeable and long-lasting.
