Do not repair before identifying the cause
An uneven epoxy coating can show as ripples, bubbles, roller lines, sagging, dry patches, fisheyes, or rough areas. Each symptom points to a different cause, so the repair should begin with inspection rather than guesswork.
Common causes
- Poor surface preparation or inadequate concrete grinding.
- Moisture vapour or contamination in the slab.
- Incorrect resin and hardener mixing.
- Applying the product too thick or too thin.
- Working outside the correct temperature or cure window.
- Dust, oil, silicone, or cleaning residue on the surface.
Repair options
Small rough areas can sometimes be sanded and topcoated. Isolated chips may be cleaned, patched, and blended. If the coating is peeling, bubbling widely, soft, contaminated, or poorly bonded, the failed coating may need to be mechanically removed before the floor is rebuilt correctly.
