About
Aliphatic urethane is a UV-stable polyurethane finish coat that holds its color and gloss in direct sunlight. We use P-AU100, a two-component aliphatic polyester polyurethane available in clear gloss, clear satin or pigmented. It resists abrasion, staining, Skydrol hydraulic fluid, betadine and hot-tire marking, and is VOC-compliant at 75.4 g/L. Typical applications include aircraft hangars, industrial kitchens, automotive showrooms, laboratories and healthcare facilities. Installation requires relative humidity below 40% and a moisture barrier on slabs with vapor transmission.
Right Fit
Not For
- Humid install days or damp slabs. It needs relative humidity under 40% and substrate moisture under 4% to cure properly.
- Slabs without a moisture barrier. Hydrostatic pressure can cause it to detach.
- Moving substrates. It's a hard finish (about 7% elongation), not a flexible membrane.

How this material handles sun, humidity, damp slabs and coastal air
Sun & Heat
Light-stable with good gloss retention — built for floors that see direct sun.
Humidity
Relative humidity must stay below 40% during application and the first 48 hours of cure. In Florida, that means conditioned interiors or carefully chosen weather windows.
Slab Moisture
Substrate moisture must be under 4%. Without a moisture barrier, hydrostatic pressure can cause detachment.
Salt Air & Pools
Resists staining and harsh chemicals, including the cleaners used in coastal commercial facilities.
