Yellowing Epoxy
Standard epoxy yellows over time when exposed to sunlight. UV-stable topcoats — polyaspartic or polyurea — solve this on sun-exposed floors. Every slab is different, so recommendations depend on an on-site evaluation — we do not diagnose specific floors from photos alone.
Common causes
- UV exposure on epoxy topcoats
- Sunlit windows over interior floors
- Exterior applications with non-UV-stable systems
How we approach it
- UV-stable polyaspartic or polyurea topcoat
- Recoat with a UV-stable system
- Awareness of exposure before specifying
Preparation
- On-site evaluation of the concrete and any existing coating
- Moisture and adhesion testing where warranted
- Full mechanical preparation before any new material is installed
- Compatible repair materials for cracks, spalls, and pits
Frequently asked
Can we fix a yellowed floor?
A UV-stable topcoat over the existing floor can restore appearance. Deep yellowing may require sanding and full recoat.
