Peeling, bubbling, and delaminating epoxy is one of the most common calls we get in the Katy area. Homeowners invest in a big-box DIY kit or a low-bid contractor, and within months the floor is lifting. The root cause is almost always inadequate surface preparation — not the epoxy itself.
What Is Epoxy Delamination?
Delamination occurs when the bond between epoxy and concrete fails. This manifests as bubbles, blisters, peeling sheets, or flaking chips. In most cases, the epoxy cured properly — it just never truly bonded. Common culprits: acid-etched (not ground) concrete, residual oil or dust, excessive moisture vapor emission, or wrong epoxy chemistry for the application temperature. The failure mode tells us the diagnosis.
Why It Matters Before Epoxy
Recoating over a failed floor without fixing the root cause guarantees the same result. The new coating will delaminate in the same pattern and timeframe as the old one. Proper repair requires removing all failed coating, identifying why it failed, correcting that condition, and then applying the right system correctly.
Our Process
- Failure mode analysis — inspect peel pattern, check bond strength, test moisture
- Old coating removal — shot blasting or grinding removes all failed material
- Root cause correction — address moisture, oil, or profile issue that caused failure
- Concrete profiling — achieve ICRI CSP 2–3 for proper epoxy bond
- Correct product selection — match epoxy chemistry to slab conditions
- Full system install — primer + body coat + broadcast + commercial topcoat
