Test the existing floor before recoating. Confirm adhesion, compatibility, contamination, moisture, and the condition of concrete beneath failed areas. Recoat only when the old system is sound enough to remain the foundation.
Separate wear from loss of bond
A dull traffic path or light scratching may be limited to the wear coat. Peeling sheets, hollow areas, widespread bubbles, or flaking at tires can indicate a bond problem below. Mark the extent and location of damage. Patterns near the threshold, cracks, or wet zones can help identify the cause.
Adhesion testing and exploratory removal may be needed. A new clear coat cannot secure a weak base layer to the slab.
Compatibility must be proven
The identity of the old coating may be unknown. Cleaners, waxes, tire products, and silicone can also remain on the surface. A restoration plan should identify or test the existing film, prepare it to the new product requirements, and use a test area when compatibility is uncertain.
If the system cannot be identified or bond is inconsistent, removal to sound concrete often creates a more defensible starting point.
Expect visible repair limits
Matching aged flake, metallic movement, gloss, and color can be difficult. A local repair may be structurally sound but still visible. Boundaries placed at joints, doorways, or full bays are often easier to blend than an isolated patch in open floor.
Decide whether the goal is functional repair, improved appearance, or a near-uniform refinish. Each has a different scope and budget.
Information that improves the assessment
Provide installation records if available, including products, age, cleaning history, and warranty terms. Photograph damage dry and after cleaning. Note when it appeared and whether it grows seasonally.

Common questions
Can a peeling epoxy floor be recoated?
Only after the cause and extent of bond loss are understood. Loose coating must be removed, and widespread failure may require full removal rather than spot repair.
Can a scratched clear coat be refreshed?
Sometimes, when the underlying system is sound and the surface can be cleaned and prepared for a compatible recoat. Test compatibility and appearance first.
Will repaired flake match perfectly?
Exact matching is uncommon because flake blends, broadcast pattern, topcoat color, and wear change over time. Full-section refinishing may provide a more even result.
