Seal Once Seal-Once Nano+Poly Ready Mix Penetrating Exterior Wood Sealer and Stain with Polyurethane in Black

Seal-once has been leading the innovation in the use of nanotechnology to create long-lasting, non-toxic wood sealers and tinted wood stains since 2005. Our New and Improved Nano+Poly Penetrating Wood Sealer provides superior protection against water damage, mold, decay and eliminates warping and cupping. Unlike most top-coat sealers, Nano+Poly deeply penetrates the surface of wood, using proprietary nanotechnology to form a flexible breathable barrier, that coats the wood fibers at the cellular level.
