Smith’s Hi-Wear 90S — Industrial Urethane Topcoat

Smith’s Hi-Wear 90S is a premium, high-traffic topcoat for the most demanding industrial floors — a low-sheen, aliphatic, UV-stable, chemical- and abrasion-resistant 90% CRU urethane. It’s engineered as the tough final wear layer over resinous flooring in environments that punish a floor: heavy manufacturing, hangars, healthcare, food & beverage, and vehicle service areas.

Key Features

• 90% solids aliphatic urethane — a dense, highly durable finish
• UV-stable — resists yellowing, even after 1,000+ hours of UV exposure
• Chemical- and stain-resistant — stands up to acids, solvents, oils, and more
• Abrasion-resistant — resists traffic patterns and finish dulling
• Excellent rolling-load resistance — for forklift and pallet-jack traffic
• Low sheen finish with improved light reflectivity
• Doesn’t harbor bacteria or fungus — meets FDA Title 21 for indirect food contact
• Low VOC, nil odor during application
• Overnight return to service

Exceptional Service Life

Hi-Wear 90S is built to last far longer than typical topcoats:

• 2× longer life cycle vs. moisture-cured urethanes
• 3–4× longer vs. polyaspartics
• 5–6× longer vs. 100% solids multi-purpose epoxy

That longevity means fewer recoats, less downtime, and lower long-term cost on high-traffic floors.
