Yes, Thompson's WaterSeal is effective for protecting wood and masonry surfaces from water damage, mold, and mildew. It creates a waterproof barrier that helps prevent moisture penetration, extending the lifespan of the treated materials. However, its effectiveness can depend on proper application and surface preparation, as well as the specific product used. Regular reapplication may also be necessary for optimal protection.
