DEFY Extreme Wood Stain is a semi-transparent wood stain formulated using state-of-the-art nano-technology to create a level of durability that simply has not been available in a wood stain finish in the past. DEFY Extreme Wood Stain is our most innovative, high-performance product yet. Ultraviolet rays cause wood to turn gray and become susceptible to water penetration and decay. DEFY Extreme Wood Stain effectively protects the wood from the harmful effects of the sun and from graying by using zinc nano-technology. Extreme Wood Stain contains zinc oxide particles that reflect the damaging ultraviolet rays from the sun. When you reduce the size of these zinc particles down to the nano level, they become invisible to the naked eye. These nano-particles are distributed at a rate of over 30 trillion per square inch of surface area to provide protection from the sun, much like sun blockers and sunscreen lotions. This will not only help to prolong the graying, but, as the nano-particles are highly resistant to mold and mildew, also helps enable retain the natural color. This 250 VOC-compliant, semi-transparent stain provides the maximum UV protection available, adding a semi-transparent tint to your wood. Extreme Wood Stain is available in six semi-transparent colors: natural pine, cedar tone, light walnut, redwood, driftwood gray, and butternut. It also comes in a clear finish. It's designed to be used on interior or exterior wood surfaces including: wood siding, log homes, decks, fences, shake shingles, outdoor wood furniture, pressure treated lumber, and all other natural wood surfaces. Applying Extreme Wood Stain is easy. A treatment of DEFY Wood Cleaner will generally clean and restore previously treated surfaces to their original appearance. Once cleaned, a quick application of DEFY Wood Brightener will brighten the wood and restore the wood's natural beauty. This deck sealer provides long-term beauty and protects the natural appearance of your wood.
