Problem 1: Peeling and Lifting
Peeling is the most common complaint and the most serious. When a coating lifts away from concrete, it's a form of Delamination.
What it usually means
The coating didn't bond well to the slab. Common reasons:
- Inadequate preparation. Concrete that wasn't ground or was only lightly etched may not give the coating enough to grip.
- Contamination. Oil, sealers, curing compounds or old paint left on the surface block the bond.
- Moisture. Water vapor rising through the slab can push coatings off.
- Product mismatch. Some products don't suit garage conditions.
How to tell what caused it
Look at the underside of a peeled piece. If it's clean and smooth, with little concrete stuck to it, the coating probably didn't bond to the surface. If concrete is stuck to the back, the bond was strong but the concrete surface itself was weak. A professional can tell more from the pattern and from moisture testing.
The fix
Peeling usually spreads, so patching over it rarely lasts. The typical fix is to remove the coating in affected areas, or the whole floor if peeling is widespread, prepare the concrete properly, address any moisture, and recoat.
Problem 2: Hot Tire Pickup
What it looks like
Peeling or marks that line up with where tires sit, often first noticed in summer.
What it usually means
Hot tires soften some coatings and, as they cool, grip and pull the coating up. Contributing factors include thin coatings, weak bonds and products not designed for hot-tire conditions. Round Rock summers bring plenty of heat, and cars coming off hot roads carry it straight into the garage.
The fix
Remove the damaged coating, reprepare and recoat with a system designed for vehicle traffic. Many garage systems use a polyaspartic topcoat partly for this reason. In extreme heat, letting the car cool before pulling in helps, especially in the first weeks.
Problem 3: Yellowing
What it looks like
The floor turns amber or yellow, often most noticeably near the garage door where sunlight reaches.
What it usually means
Many epoxies yellow with UV exposure. It's often cosmetic rather than a sign of failure, but it can be very visible on light colors.
The fix
If the floor is otherwise sound, a recoat with a UV-stable topcoat, such as a polyaspartic, can restore the color. Keeping the garage door closed when not in use reduces exposure.
Problem 4: Bubbles, Pinholes and Craters
What it looks like
Small holes, raised bubbles, or crater-like spots in the finish.
What it usually means
- Outgassing. Air escaping from the concrete as it warms can push up through a wet coating, especially if it's applied as the slab is heating.
- Application conditions. Temperature, humidity and how the product was mixed and applied all play a part.
- Contamination on the surface can cause small craters called fisheyes.
The fix
Small areas can often be sanded and recoated. Widespread bubbling may need a broader recoat. Good installers time application to reduce outgassing, often applying as the slab is cooling.
Problem 5: White, Cloudy or Blotchy Areas
What it looks like
Milky or white patches, sometimes appearing after rain or humid weather.
What it usually means
Often moisture-related: either moisture in the slab or humidity during application. Sometimes it's a residue from cleaning products.
The fix
First, rule out cleaning residue by washing with clean water. If it persists, have moisture assessed. Depending on the cause, the fix may be a recoat or, if moisture is pushing up from below, a moisture-mitigating system.
Problem 6: Cracks Through the Coating
What it looks like
Lines appearing in the coating, often following old slab cracks or control joints.
What it usually means
The slab is moving. Central Texas clay soils expand and shrink with moisture, and the eastern side of the Round Rock area in particular includes clay-rich ground. Movement can reopen cracks beneath a coating.
The fix
Crack repair and a local recoat. Be aware that actively moving cracks may come back. A good installer will explain which cracks are likely to stay stable and which may not.
Problem 7: Chips
What it looks like
Small missing pieces, often at edges, thresholds, or where tools are dropped.
What it usually means
Impacts, thin edges, or wear at the door. Isolated chips are common and don't usually mean the floor is failing.
The fix
Clean the area, and have it touched up with a compatible product. Avoid DIY patches with different products, which can look obvious and may not bond.
Problem 8: Dull, Worn or Scratched Areas
What it looks like
Matte paths where cars park or people walk.
What it usually means
Grit has worn the topcoat. Harsh cleaners can contribute.
The fix
Clean thoroughly, then recoat the topcoat. It's a relatively light job if the floor beneath is sound. Better sweeping habits help prevent it recurring.
Problem 9: Soft or Tacky Areas
What it looks like
Spots that stay sticky or soft long after installation.
What it usually means
A mixing or curing problem, such as incorrect ratios or incomplete mixing.
The fix
The affected material usually has to be removed and redone.
Problem 10: Flake Coming Loose
What it looks like
Flake pieces lifting, or a rough surface that catches dirt.
What it usually means
Not enough topcoat over the flake, or loose flake not scraped before topcoating.
The fix
Scrape, clean and apply an adequate topcoat.
Repair, Recoat or Replace?
| Situation | Usual approach |
|---|---|
| Isolated chips, sound floor | Repair |
| Dull or yellowed, sound floor | Recoat |
| Small bubbled area | Repair or local recoat |
| Peeling in one area | Remove and redo that area, after finding the cause |
| Widespread peeling | Full removal and replacement |
| Moisture pushing coating off | Address moisture, then replace |
The key question is whether the bond to the concrete is sound. If it is, a repair or recoat is usually enough. If it isn't, coating over the problem won't fix it.
How to Test Whether Your Floor Is Sound
A few simple checks before calling anyone:
- Tap test. Tap the floor with a coin or the handle of a screwdriver. A hollow sound can indicate lifting.
- Edge check. Look closely at chip edges. If coating flakes away easily around a chip, the bond may be weak.
- Spread check. Photograph problem areas and compare after a few weeks. Spreading peeling points to a bond problem.
- Moisture clue. Tape a square of clear plastic to bare concrete in a peeled area for a day or two. Condensation underneath suggests moisture. It's not a formal test, but it's a useful clue to mention.
DIY Fixes That Often Make Things Worse
When a floor starts failing, it's tempting to grab a kit from the hardware store. Some common moves backfire:
- Painting over peeling areas. New paint bonds to the failing coating, not to concrete, so it peels along with it.
- Applying a DIY kit over a professional coating. Without proper abrading, the new layer often won't stick, and mismatched products can react.
- Using strong strippers. Some strippers soak into concrete and leave residue that blocks the next coating's bond.
- Grinding small patches with hand tools. This can leave uneven edges and gouges that show through any recoat.
- Sealing in moisture. Coating over a damp area without addressing the moisture usually leads to the same failure again.
If you want to do something while you wait for an assessment, keep the area clean and dry, photograph it, and avoid parking directly on lifting sections.
Problems in Commercial Floors
Commercial floors fail in similar ways, with some extra causes:
- Chemical attack from cleaners, food acids or industrial fluids that the system wasn't designed for.
- Thermal shock in kitchens, where hot water and cold surfaces meet.
- Heavy wheeled traffic, such as pallet jacks and forklifts wearing through thinner systems.
- Wet areas and drains, where water gets under edges.
Fixing them often means choosing a different system rather than repeating the original one.
Hypothetical Examples
The two-year-old flake floor peeling in tire paths
A homeowner's floor was coated with a single-layer product after acid etching. Peeling began in the tire paths during the second summer. The likely causes are light preparation and a system not suited to hot tires. The fix: full removal, diamond grinding, and a multi-coat system with a polyaspartic topcoat.
The yellowed solid gray floor
A solid gray epoxy floor has turned amber near the door, but the bond is sound and there's no peeling. The fix: clean, abrade and apply a UV-stable topcoat, with no need to remove the base.
The shop floor with white blotches
A workshop floor shows cloudy patches after wet weather. A moisture clue test shows condensation under the plastic. The fix: a proper moisture assessment, then a moisture-mitigating base before a new system.
When the Problem Started Matters
The timing of a problem is one of the most useful clues:
- Within days or weeks: often an application or curing issue, such as mixing, temperature or parking too soon.
- Within the first year: often a preparation or bond problem, or hot tire pickup in the first summer.
- After several years: often normal wear, UV exposure or slab movement.
Note when you first saw each problem and whether it's changing. Share that with whoever assesses the floor.
Documenting a Failed Floor
Before anyone works on the floor, gather:
- Daylight photos of each problem area, wide and close up.
- The original estimate or invoice, if you have it.
- Product names, if known.
- Notes on when problems started and how they've changed.
- Any information about the slab's age and past repairs.
This helps a contractor diagnose the cause and quote accurately, and it's useful if you need to raise the issue with the original installer. If the original installer is still in business, contact them first: they know exactly what was applied, and they may want the chance to put it right. Keep your communication with them in writing.
Questions to Ask a Contractor About a Failed Floor
- "What do you think caused this?"
- "How will you remove the existing coating?"
- "How will you check for moisture?"
- "What system would you use instead, and why?"
- "Can any of the existing floor stay?"
- "What will stop this happening again?"
A contractor who explains the cause before quoting a fix is more likely to solve the problem.
Cost of Fixing a Problem Floor
Removing a failed coating takes more work than preparing bare concrete, so a replacement often costs more than a first-time installation of the same size. For reference, our published ranges for new work are $800–$1,200 for a 1-car garage, $1,400–$2,200 for a 2-car and $2,000–$3,200 for a 3-car garage, polyaspartic systems at $3–$7 per square foot, metallic at $6–$12 per square foot and commercial at $2–$5 per square foot. Removal of an old coating is typically quoted on top of that after a site visit. Recoats and repairs of sound floors usually cost less.
Preventing Problems on Your Next Floor
- Choose thorough preparation, usually diamond grinding.
- Ask about moisture testing.
- Choose a system suited to vehicles and sun.
- Make sure flake is fully topcoated.
- Follow cure times.
- Keep up basic care: sweep, clean spills, use pads.

Frequently Asked Questions
Why is my epoxy garage floor peeling?
Usually because the coating didn't bond well, often due to inadequate preparation, contamination or moisture in the slab.
What is hot tire pickup?
It's when hot tires soften a coating and pull it up as they cool. Thin coatings and weak bonds make it more likely.
Why is my epoxy floor turning yellow?
Many epoxies yellow with UV exposure. If the floor is sound, a recoat with a UV-stable topcoat can help.
Can I just coat over a peeling floor?
Usually not. Coating over a bad bond rarely lasts. The failed coating normally needs to be removed and the concrete reprepared.
What causes bubbles in an epoxy floor?
Often air escaping from the concrete as it warms, application conditions, or surface contamination.
Is fixing a failed floor more expensive than a new one?
Often, because removing the old coating adds work. Repairs and recoats of sound floors usually cost less.
