Understanding Thompson’s Waterseal
Thompson’s Waterseal is a popular waterproofing product designed to protect wood and other surfaces from water damage, mildew, and UV rays. It comes in different formulas, including clear, semi-transparent, and solid colors, which is great depending on how much natural wood grain you want to show.

Cons to Keep in Mind
