Troubleshooting
Dealing with Garage Floor Cracks Before Coating
Cracks in your garage floor do not automatically disqualify it from coating. The type of crack, its cause, and whether it is still moving all determine the right repair approach.
What you need to know
- Hairline cracks and control joint cracks are normal in concrete and can be filled during prep.
- Structural cracks that are actively moving may need flexible filler or additional evaluation.
- Spalling (surface flaking) is usually caused by moisture or freeze-thaw cycles and needs to be ground smooth.
- All cracks should be repaired before coating to prevent them from telegraphing through the finish.
- Our crews assess every crack during the in-garage appointment and include repair in the project scope.
If you're dealing with this issue, the fix usually starts with a proper slab assessment. We can take a look and give you honest options — no obligation.
