Yes, it is generally a very good idea to seal your deck after pressure washing. Power washing removes not only dirt and debris but also a thin layer of wood, leaving the surface exposed and more susceptible to weathering. Sealing is almost always needed after this process. After a general cleaning, sealing isn't automatically necessary if the existing sealant is still intact. You can test the surface by placing a few drops of water on it. If the water beads up, the sealant is working. If it soaks into the wood, it's time to apply a new sealant. If it has been a few years, it's wise to remove the old sealant, wash the deck, and reseal for maximum protection.

Satin paint is generally considered a better choice for woodwork—including trim, baseboards, cabinets, and doors—than flatter finishes like eggshell or matte. Its soft sheen enhances architectural details and stands up well to frequent cleaning and daily wear. Compared to eggshell and matte finishes, satin is more durable for high-touch areas because it is less porous and doesn't absorb dirt as easily. Matte finishes, in particular, are prone to scuffs and are harder to clean, making them less practical for surfaces like doors and cabinets.

Opt for an interior wood stain that is rated for your type of wood. Consider your personal style preferences as well as the overall use of the room when choosing a color. Remember, the color you see at the store may look different on your actual floors once applied. This is why if you have the chance, it’s helpful to test a few options on a scrap piece of wood in the room first. Once you narrow it down, you can test a small patch on an inconspicuous area in the room to see it on the actual floors.

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.
