Centennial Seal™

CENTENNIAL SEAL™ - WOOD SEALER AND MOISTURE PROTECTION Protect your investment without changing what makes it beautiful. Centennial Seal™ is a water-based, eco-friendly wood sealer and moisture barrier developed by Centennial Woods to protect reclaimed Wyoming snow fence wood against UV exposure and water damage without altering the natural patina that makes each plank unique. Sold by the quart as a concentrate that mixes with water on-site, one container covers up to 437.5 sqft once diluted. WHAT CENTENNIAL SEAL DOES Reclaimed wood carries a lot of character. Years of weathering in Wyoming's high-altitude climate create a texture and tone that simply can't be faked. Centennial Seal is designed to help maintain and protect that look while forming a breathable barrier against the elements that can degrade even the toughest exterior wood surfaces over time. Key Benefits UV Protection Shields exterior wood surfaces from direct sunlight and sun fading Preserves Natural Patina Clear drying formula that does not alter the appearance of your wood surface Eco-Friendly Formula Water-based, nano-technology sealer with no harsh solvents Water Damage Defense Seals wood fibers against moisture and water intrusion without trapping humidity inside Long-Lasting Protection Lasts approximately 5–10 years, depending on exposure levels BUY BY THE QUART Centennial Seal is available in 1-quart concentrate containers at $91.65 per quart. Mixed with 2.5 gallons of water, each quart covers approximately 437.5 sqft as a single-coat system, working out to roughly $36.66 per finished gallon. The concentrate also doubles as an end-cut treatment for exterior siding installs when used undiluted, giving installers one product for both broad-surface application and end-grain protection. Centennial Seal can still be pre-applied to your order at our facility, though that option may increase lead time depending on order size. For those who'd rather handle applications on-site, ordering by the quart gives you that flexibility. WHERE TO USE CENTENNIAL SEAL Centennial Seal works for both interior and exterior use, though it's most valuable on wood surfaces where UV exposure and moisture are ongoing concerns. Exterior Wood Siding: Direct sunlight and moisture are the two biggest threats to reclaimed wood siding over time. Centennial Seal creates a protective layer that slows UV degradation and keeps water from penetrating the wood surface. Patio Wood Walls: Exterior wood walls on patios are still exposed to shifting seasonal conditions. Centennial Seal provides the UV and moisture protection needed to keep them looking their best year-round. Bathrooms and Humid Interior Spaces: Guards against humidity without darkening the finish. Always spot-test before applying to verify compatibility with your finish color. Accent Walls and Staircases: Helps maintain the wood surface in high-traffic spaces where moisture from cleaning or spills is possible. APPLICATION OVERVIEW Mix the Concentrate: Combine 1 quart of Centennial Seal with 2.5 gallons of clean water and stir thoroughly until fully blended. Prepare Your Surface: Start with a clean, dry wood surface free of dust and debris. Do not use other sealants without spot-testing first, as many will darken the wood significantly. Apply in Small Sections: A polyester brush, pad applicator, or airless sprayer with a variable tip all work well. Working in small sections helps ensure even coverage, especially on vertical surfaces. Treat End-Cuts Separately: For exterior siding installs, apply undiluted concentrate directly to any cut ends exposed during installation to protect the more porous end-grain from moisture intrusion. First Coat and Second Coat: Apply the first coat and allow it to penetrate fully. On dry or porous wood, a second coat is often recommended for long-lasting protection and the best results. Allow adequate dry time between coats. CENTENNIAL SEAL VS. OTHER WOOD SEALING PRODUCTS Many wood sealers on the market use oil-based stains, linseed oil, or tung oil as a base. Those products work well on raw or unfinished wood, but they can significantly darken weathered reclaimed wood. Polyurethane finishes have the same problem, tending to film over the surface rather than penetrate it. Centennial Seal uses nano-technology to penetrate the wood surface at the fiber level, creating a water-resistant and UV-protective barrier without the color shift most off-the-shelf products cause. For exterior use on siding, paneling, or any other exposed application, that means long-lasting protection without sacrificing the natural look of the wood. No glossy finish, no dark staining. Just clean, natural-looking results. READY TO PROTECT YOUR PROJECT?
