Bubbling Epoxy
Bubbles form when air or moisture escapes through wet coating. Cause can be outgassing from concrete, moisture drive from below, or roller and application technique. Every slab is different, so recommendations depend on an on-site evaluation — we do not diagnose specific floors from photos alone.
Common causes
- Concrete outgassing during cure
- Moisture from the substrate
- Overworking the wet film
How we approach it
- Prime with an outgassing-tolerant material
- Test moisture and mitigate as needed
- Correct application technique
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 bubbles be repaired?
Isolated bubbles can be sanded and touched up. Widespread bubbling means the base needs to be addressed and the coating re-installed.
