Find the Right SEAL-ONCE Product for Your Project

SEAL-ONCE® has been leading the innovation in the use of nano-particle technology to create long-lasting, Eco-friendly wood sealers & tinted wood stains since 2005.  Our EXOTIC Waterproofing Wood Sealer & Stain is water-based, ultra-low VOC & engineered to penetrate dense Brazilian hardwoods like Ipe, Teak & Mahogany.  Tropical wood species are denser than North American hardwoods & EXOTIC deck sealer has been specifically engineered to protect & preserve exotic wood finishes.

Unlike most top-coat sealers on the market today, SEAL-ONCE penetrates deep below the surface to form a long-lasting water-resistant shield around the wood fibers.  The added POLY in EXOTIC creates a surface coating for superior abrasion resistance in high-traffic areas that make it a great choice for protecting Ipe wood decks.  It is non-yellowing & the clear formula will not alter the natural beauty of tropical woods. The tinted formulas provide additional protection from the sun on Ipe decking, siding & walkways.

EXOTIC has none of the toxic chemicals common in oil & solvent based wood sealers & stains, so it can be applied safely around homes, landscaping & vegetation.  SEAL-ONCE is warranted to prevent long-standing water accumulation for up to 10 years on vertical & up to 6 years on horizontal surfaces.
