Description
Thompson's WaterSeal 1-Gallon Woodland Cedar Waterproofing Stain is a solid-color waterproofing sealer that protects wood while enhancing its natural texture with a warm cedar tone. You’ll want it when outdoor wood needs long-lasting defense against rain and sun: decks, fences, siding and outdoor furniture benefit from its boldly tinted sealer and integrated sunblock. Formulated to meet the industry standard ASTM D4446 for waterproofing wood, it helps prevent water damage and delivers a mold- and mildew-resistant finish for cleaner-looking surfaces. The solid finish provides durable protection from both moisture and UV exposure, preserving appearance and extending the life of wood exposed to the elements. Made in the U.S., this stain is ideal for homeowners seeking reliable, color-rich weatherproofing for exterior wood projects.
