Smiths Poly-SEAL Semi-Gloss or Low Sheen finish 1 GL



Smith's Poly-SEAL Semi-Gloss or Low Sheen finish 1 GL

Single component solvent-based acrylic polymer

Smith’s Poly-SEAL is a single component, fast drying, waterborne polyurethane polymer fused with a cross-linking acrylic which achieves a tenacious bond to approved substrates, with very good resilience, longevity, U.V. stability and wear.

Smith’s Poly-SEAL may be used as a primer for interior and exterior direct-to-concrete applications prior to Smith’s Poly WB topcoat, as a seal coat to lock down Vinyl Chip prior for residential garage floor systems, finish for Terrazzo as a replacement for traditional floor wax in addition to a standalone architectural and decorative concrete sealer for concrete overlays, Stucco, pavers and more.

Smith’s Poly-SEAL is available as a standard / semi-gloss finish or an optional low sheen finish. Solid colors can be achieved by adding Smith’s WSC Waterborne Solid Color Packs (sold separately).
