My DIY epoxy kit failed. What does it cost to grind it off and start over?

Most DIY epoxy kits rely on acid etching for prep, and acid etching is the number one reason they fail. Etching cannot remove curing compounds, old sealers, or laitance from the slab surface. The coating bonds to that weak layer instead of clean concrete. When the layer lets go, the coating goes with it. Professional installers grind the slab with diamonds instead, because a coating needs an open, porous profile to anchor into.

Kit thickness is the second problem. Users commonly report that a single box covers less area than the label claims, so the coating goes down thin to stretch it. A film measured in a few mils cannot survive a 4,000 pound vehicle, hot tires, and dropped tools. Users also report peeling within months, not years. None of that means you did anything wrong. The product and the prep method set you up.

A new coating bonds to whatever it touches, and on a failed floor that means failed epoxy. Any product applied over loose, poorly bonded film inherits that weak bond. The old coating keeps letting go on its own schedule and takes the new layer with it. You pay twice and end up at the same place.

Spot fixes have the same problem at smaller scale. You can scrape and patch the peeled areas, but the surrounding film failed the same prep and the same thin build. New peeling starts at the patch borders. If moisture vapor drove the failure, no topcoat fixes it, because the pressure comes from under the slab, not from the surface.

A professional redo takes one day, not another lost weekend. Slabbr grinds, repairs cracks with rigid polymer at no extra charge, applies the base coat, broadcasts flake to refusal, and topcoats the same day. You walk on it in 24 hours, park in 72, and move your contents back the next day. You also pick from 700 plus Torginol flake blends instead of the 3 colors on a shelf.

The chemistry changes too. Polyaspartic does not amber in UV and does not soften under hot tires, the two failures that killed your kit. Every layer we install is polyaspartic, and the Ironclad build at $10 per square foot runs two topcoats for the hardest wear.
