Garages with the door open all day, sunrooms, patios and front porches all need a coating that can take direct UV exposure without yellowing, chalking or softening. Standard epoxy can't — it ambers within months in Huntsville sunlight. Our UV-stable aliphatic polyaspartic topcoats are engineered for the job.
Why Standard Epoxy Yellows in the Sun
Epoxy resin contains aromatic groups that oxidize under UV, turning the coating amber-yellow and slowly chalking the surface. In a Huntsville garage with the door open most days, you'll see visible yellowing inside 6–12 months on a pure epoxy topcoat.
Aliphatic Polyaspartic — The Real UV Solution
Aliphatic polyaspartics are the same chemistry used on bridge decks, runways and exterior architectural finishes. They're 100% UV stable, won't yellow or chalk, and stay flexible enough to handle thermal cycling. Every UV-exposed Huntsville Floor Coatings project gets an aliphatic polyaspartic topcoat — not a cheaper aromatic substitute.
Best Use Cases in Huntsville
Garages with the door open most of the day, sunrooms with floor-to-ceiling windows, covered porches and patios, pool decks, and any commercial entryway with direct sun. We also use UV-stable systems for showroom floors with large skylights or glass walls.
