Garage Floor Coating Removal and Recoat in Clovis
Epoxy Floors Field Clovis covers removal and recoating of failed garage floor coatings in Clovis — peeling at the door, bubbles, amber tint, a builder's sealer that has let go — with a table pairing each symptom with its likely cause before anyone decides what to recoat.

Match the symptom to the likely cause
| What you see | Likely cause in a Clovis garage |
|---|---|
| Sheets lifting, usually at the door | Poor bond: etched only, damp or oily at coating time |
| Bubbles or pinholes | Air or vapor escaping as the slab warmed during the cure |
| Amber tint near the door | An epoxy top coat in strong afternoon sun |
| Marks shaped like tires | Hot-tire pickup on a thin or poorly ground film |
| Cloudy or tacky spots | Mixed wrong, or cured too cold or too humid |
| Small flakes all over | A thin kit coat or a sealer, not a thick film |
| Chipped edges | Impacts on a thin film |
Two causes can share one floor; a coating that peels at the door may be damp underneath and badly ground as well.
When a builder's sealer lets go
Garages in newer tracts sometimes show trouble within the first year or two. Two stories repeat: a coating applied before the slab had dried, or one rolled straight over the builder's curing compound or clear sealer. A slab can pass 28 days and still hold too much moisture, and each system carries its own limit.
On a young slab it is rarely the concrete that failed; it is the layer where coating meets slab. Removal takes off the failed film and whatever it clung to, and a moisture test before the next coat confirms the cause is gone.
Test first: older paint, tile and black adhesive
Paint or wall texture in a garage built before 1980 can contain lead or asbestos, so it is tested before any sanding or grinding. Old vinyl floor tile and black adhesive (cutback mastic) can contain asbestos as well; samples are tested before removal, and asbestos work is done only by contractors registered for it.
Garages near Old Town are the likelier candidates, since some slabs were tiled or painted in earlier decades. A newer tract garage seldom raises the question, but a quote should still say what was checked.
Four ways an old coating comes off
| Method | Best for | Trade-off |
|---|---|---|
| Diamond grinding | Thin epoxy, paint, most failed films | The common choice; dust is controlled with a shroud and vacuum |
| Shot blasting | Thick or stubborn coatings on a sound slab | Fast on large areas; needs a machine with dust collection |
| Scarifying | Thick build-ups and mastic residue | Aggressive; leaves a rough surface to be ground again |
| Chemical strippers | Small patches and edges | Messy and slow; the residue needs thorough cleanup |
After removal, cracks are filled and ground flush, and the slab is tested for moisture before anything new goes down.
Recoat over it, or take it off
- Sound and well attached, only dull or scratched: a light scuff and a new top coat can work.
- Peeling in places: the loose parts are removed, but the edges of a failing film keep failing.
- Amber or soft: an epoxy top coat that has turned in sun can be scuffed and covered with a more UV-stable top coat only if the bond underneath is good.
- Failed over a large area, or damp: all of it comes off, and the cause is fixed before the new system goes down.
A coating that flakes under a fingernail is not a candidate for a recoat. Ask the installer to test the bond and show the result.
What removal adds, by garage size
In the estimator, removing an old coating typically adds $1–$3 per square foot to the new floor. Flake epoxy at $5–$8 therefore becomes $6–$11 per square foot once the old film is off.
| Garage | Removal alone (+$1–$3) | Flake floor with removal ($6–$11) |
|---|---|---|
| 1-car, 240 sq ft | $240–$720 | $1,440–$2,640 |
| 2-car, 400 sq ft | $400–$1,200 | $2,400–$4,400 |
| 3-car, 700 sq ft | $700–$2,100 | $4,200–$7,700 |
Thick multi-layer coatings, mastic and heavy oil push the price toward the upper end. Market estimates, not quotes.
Garage Floor Coating Removal and Recoating — common questions
Why did my garage floor coating peel within a year or two?
Usually the slab was damp, was etched but not ground, or carried a builder's curing compound or sealer under the coat. The symptom table pairs each sign with its likely cause.
Should old garage paint or tile be tested before removal?
Yes. Pre-1980 paint and old vinyl tile with black adhesive can contain lead or asbestos, so samples are tested first, and asbestos work is done only by contractors registered for it.
