At ProTrade Warehouse, we offer XPS Rockhard Water Based Urethane, a premium 2-component high water-based urethane designed to deliver high gloss, UV stability (non-yellowing), low odor, and exceptional abrasion and chemical resistance. This new generation coating provides an ideal balance of pot life, cure time, recoat ability, return to service, and long-term performance. With its very low odor, it can be applied indoors in occupied areas and is suitable as a clear or pigmented finish for resinous decorative and industrial flooring. Available in a range of gloss levels.
Rockhard Water-Based Polyurethane is a top-tier, high-performance, long-lasting, and versatile protective coating. High-wear surfaces are an ideal use for this product
Features and Benefits
- Very low odor
- Excellent pot life
- VOC compliant
- ADA compliant (slip coefficient > 0.6)
- Excellent adhesion
- Outstanding chemical resistance
- Easy maintenance
- matte & gloss finish
- ideal for interior applications
Limitations
- Not recommended for use over wet or damp substrates
- Avoid applications with active moisture vapor transmission
- Best applied at temperatures between 50°F to 85°F

Coverage
Typically spreads at 400–500 ft² per gallon to yield 1.4–2 mils. Up to 3 mils is possible in one application but will require longer cure time for full hardness. Do not exceed 4 mils, as micro bubbles may form, resulting in a white haze.
