What's the Different Between a Sealer and a Waterproofer? Sealers and waterproofers perform similar functions, but they differ slightly in how they work. A wood or concrete sealer will protect the surface. Waterproofers are more durable than sealants because they penetrate the surface, filling in leaks or gaps.
Oil-based wood sealers are more durable and longer lasting. Unlike water-based solutions, oil-based wood sealers tend to penetrate deeper into the wood. This type of wood sealer emits toxic fumes and is flammable during the application process, so it's recommended that you apply it in a well-ventilated area.
Polyurethane Wood Finish
Polyurethane wood finishes are synthetic coatings that are highly durable and water resistant, making them the best clear coat for wood protection.
Before you can do that, though, you need to prep your deck for resealing. This includes cleaning it thoroughly so the new sealant can better penetrate the wood.
There are two basic product categories for waterproofing: stains and sealants. Stains are used on wood to enhance color and make them weather resistant. Sealants protect concrete and wood from moisture but do not stop water movement through the concrete from the outside.

Fungicides to defeat brown rot include: baking soda, hydrogen peroxide, tea tree oil, boron solutions, ethylene glycol or propylene glycol, vinegar, etc. Since the dry rot fungus requires an acidic environment from pH 0 to 5.5, certain of these fungicides work because they change the pH.
Can Water Seal be used on wood? Applying Water Seal will not damage wood, but the level of waterproofing protection will vary depending on the type of wood being treated. For best results, we would recommend a dedicated preserver to protect exterior timber from rot.
