- MARINE SEALANT: Our liquid formula creates a UV-stable coating for protection against the elements, saltwater spray, and water damage. Marine is a protector for outdoor decks, thermally modified wood, and boat docks. Marine is safe for use over open water and is non-hazardous to aquatic life. ** This product is NOT intended for hardwoods such as ipe, mahogany and teak. **
- DECK STAIN: It's water-based, ultra-low VOC, enhancing the extended life of your flooring, siding, and porch. The paint forms a water-resistant shield around wood fibers at the cellular level to help preserve the natural color
- WATERPROOF WOOD SEALER: The wood used on boat docks, decks, and wood retaining walls near rivers, lakes, oceans, and ponds is subjected to constant moisture. We crafted a sealer, remove stain, and finish all in one, specifically for these installations
- WOOD SEALANT: Our fast-drying protector penetrates wood below the surface, coating the wood fibers at the cellular level, which creates a long-lasting, flexible, breathable barrier. It provides a no-fuss, easy clean-up with soap and water
- SAFE FORMULA: Our user-friendly wood sealers and stains are an effective way to protect your lumber or concrete against water damage. When you use Seal-Once, our products will not harm pets, plants, or people
