Why some coatings turn amber in sunlight, how polyaspartic topcoats resist it and what to expect near open doors.
Sunlight changes some coatings. Many epoxies shift toward amber when UV light hits them, which is most noticeable on clear or light-colored floors near open doors and windows. Polyaspartic topcoats are designed to resist that change, which is a big reason they have become popular for garages and outdoor surfaces. Even the best finish may show small differences over time, but the change is much less dramatic.
If your garage faces west, has large windows or the door stays open, UV stability is worth weighing. A clear or light flake floor shows yellowing sooner than a dark one. Nashville gets strong summer sun, so sunny garages often benefit from a UV-stable topcoat. We explain which products we use, why and what changes to expect. If you have an older floor that has turned amber, a new polyaspartic topcoat after proper prep can renew it.
Open doors and windows bring UV into the garage.
