It handled Thompson’s WaterSeal smoothly, with a clear tank, three spray options, and a shield that keeps siding splash-free. It’s light, easy to pump, and simple to clean, making it the most versatile for home projects.
Top Recommendation: Chapin 25012 1-Gallon Deck Sprayer for Cleaners/Sealants
Why We Recommend It: The Chapin 25012 offers a translucent 1-gallon tank for precise filling, three poly fan nozzles for adjustable spray patterns, and a Total Control Spray Shield to protect nearby surfaces.

What Is Thompson Water Seal and How Is It Used?
Thompson Water Seal is a brand of water-repellent sealant designed to protect wood, masonry, and other porous surfaces from water damage and deterioration. This product works by penetrating the material to form a protective barrier against moisture, mildew, and UV damage, thereby extending the lifespan of outdoor structures such as decks, fences, and furniture.
