#1 Rated penetrating end sealer for cut ends of wood decks, steps & walkways

Protection for wood decking starts at the first cut. Applying a high-quality end sealer to freshly cut ends of deck boards, protects against drying cracks, splits, water damage & decay. Durable, Eco-friendly protection is provided by our long-lasting, water-based SEAL ENDS ONCE. End cuts of wood decks & lumber dry out faster than the center, which can lead to unsightly end checks (drying splits) that can spread quickly. These end cuts also expose lumber to the elements and require added protection to prevent water intrusion that can lead to mold, mildew, warping & cupping.
Our penetrating formula is the best protection for your deck and lumber. It is a great investment to preserve the look of your wood deck, railings and steps. SEAL ENDS ONCE uses a proprietary nanotechnology to form a flexible, breathable barrier by coating the wood fibers at the cellular, unlike most wax end sealers that form a wax top-coat. SEAL ENDS ONCE is the best choice to seal the ends of your deck.
Warranted to prevent long-standing water accumulation for up to 10 years on vertical & up to 6 years on horizontal surfaces. Not recommended for concrete driveways or garage floors.
Recommended for cut ends of all soft & hardwood lumber including:
Cedar Ipe Mahogany Cumaru Bamboo Timbersil Redwood Tigerwood Fir Pressure treated lumber Teak Brazilian Cherry
