Peeling, chipping, or lifting coatings need more than a fresh topcoat. Regina Concrete removes the failed system entirely, inspects and repairs the concrete slab underneath, then installs a complete coating system with proper mechanical prep so the new floor actually bonds. The result holds because the foundation is sound.
A coating that peels at the tires or lifts in patches almost never failed because the product was bad. It failed because the slab was not mechanically ground or shot-blasted before the coating went down. Dust, sealer residue, or moisture on the surface prevents adhesion, and the coating separates within months.
Fixing it means stripping the failed epoxy or polyaspartic back to bare concrete. Once the slab is exposed, cracks are routed and filled, pitted areas are patched, and the surface is profiled fresh. Only then does the new coating go on.
The second install succeeds because the prep is done right. Whether you choose metallic epoxy for looks, polished concrete for no coating at all, or standard garage floor coating, the slab is ready to receive it.

The repair sequence
How Garage Floor Repair Gets Done Right
Inspect the failure
We examine where and how the coating is failing, peeling at edges, lifting under tires, or separating in patches, to understand whether the slab itself is sound or if there are cracks or moisture issues underneath.
Strip the failed coating
Mechanical grinding or shot-blasting removes the old coating completely, exposing the bare concrete slab so we can see what we are working with and ensure the new system bonds to solid substrate.
Repair the slab
Cracks are routed and filled with epoxy or polyurethane, spalled or pitted areas are patched with repair mortars, and moisture is tested to confirm the slab is ready for a new coating.
Install the new system
Primer, body coat, and topcoat go on in sequence at the right temperature and humidity, with proper cure time between coats, so the coating performs as the manufacturer tested it.
Not a quick fix
Why Coating Over Peeling Concrete Fails Again
Applying a new coat over a peeling or lifting coating is a temporary patch, not a repair. The new coat will lift wherever the old one is lifting because the bond is still broken underneath. Real garage floor repair removes the failed system entirely.
Once the slab is bare and repaired, the choice of coating matters. Polyaspartic cures fast if downtime is a concern, polished eliminates coating altogether, or epoxy offers durability at a lower cost. The key is that the slab is prepped and the system is installed completely, not rushed or cut short.
Why coatings fail, what the repair process looks like, and how to avoid repeating the same mistake.
Almost always because the slab was not mechanically prepped before the coating went on. Coatings rolled over a sealed or dusty slab cannot bond, and they peel at the tires within a season. The fix is to strip back and prep properly the second time.
No, and no honest installer would. A coat over a peeling coating just delays failure; the new coat lifts wherever the old one is lifting. Real repair strips back to bare concrete first, then rebuilds the system properly.
Depends on why the first one failed and how you use the garage. Often the original choice was right, just installed wrong. Sometimes a different system, polyaspartic or polished, is the better fit for the use.
Yes. Cracks are routed and filled, spalled and pitted areas are patched with repair mortars matched to the coating that will go over, and the surface is profiled fresh so the new system bonds to sound substrate.
Usually a few days from strip-back through new install, depending on coating type and cure windows. Polyaspartic rebuilds finish in about a day; epoxy takes longer to fully cure for vehicles.

What Regina Homeowners Say About Their Garage Floor Repairs
Previous epoxy peeled by the door within months. They ground it all back, prepped right, and re-installed the same brand of product. Two years later still solid where the original lasted one season.

Switched from a basic epoxy to polyaspartic during the repair because we cannot afford the downtime again. Done in a day this time, has held up perfectly.

Honest assessment that the failure was prep, not product. Repair was thorough, the new floor bonds to the slab like it should have the first time.

Stripped the failed metallic coating and went polished instead. No more coatings to worry about, the slab itself is the finish now.
