Single Coat Extreme Wear Tri-Component Oil Polyurethane

Smith’s Hi-Wear 90S is a satin finish, Aliphatic, 3 component clear or 4 component pigmented chemical resistant urethane for use in high traffic environments needing a chemical and abrasion resistant UV Stable satin finish topcoat for interiors and exteriors. Applied in one coat over our microcement on interior surfaces, including showers and countertops, this product provides unparalleled strength and stain resistance. Both chemicals, paint stripper and foods such as mustard, ketchup and red wines all tested excellent with this sealer. For exteriors it is recommended to apply two layers of smith poly seal prior to application of the High wear 90s, resulting in a thicker more durable finish. This product is naturally slip resistant due to the addition of aluminum oxide that provides extreme durability and a slight sandpaper texture to your walls or floor. This product cannot accept other coats without being aggressively abraded and is recommended as a single coat application.

Surface Finish & Food Contact Notice

Our microcement systems are sealed using high-performance architectural coatings selected for superior durability, stain resistance, and long-term performance. These sealers are not specifically certified for direct food contact under FDA, Health Canada, or NSF food-contact standards.

All finished surfaces are non-porous, sealed, and suitable for everyday use in residential and commercial environments. However, they are not intended to be used as direct food preparation surfaces. We recommend the use of appropriate food-safe barriers (such as cutting boards or preparation mats) for any direct food contact.

By proceeding with our services, the client acknowledges and accepts the materials and systems specified, including their intended use and limitations. The client agrees that it is their responsibility to ensure that the use of the surface aligns with applicable health regulations, operational practices, and intended applications.

For commercial environments, including but not limited to restaurants and cafés, compliance with all local health codes, inspection requirements, and food safety practices remains the responsibility of the owner/operator.

No representation or warranty is made that finished surfaces are certified as food-safe or food-grade for direct contact.
