Garage Floor Prep: What Happens Before the Pretty Flake
What professional garage floor prep includes — grinding, crack repair, moisture checks — and why skipping it causes peeling.
The shiny flake photos get all the attention. Prep is where coatings succeed or fail. Professional installs typically include mechanical grinding to open the concrete profile so coatings can bond.
We look for cracks, spalls, joint issues, and moisture. Oil contamination needs special attention. If an old coating is failing, it may need full removal rather than a cover-up.
Prep is dusty and industrial — that is normal. We contain the work as much as practical and leave you with a clear schedule for when the garage can be used again.
If a quote seems too cheap, ask what prep is included. Thin paint rolled over dirty concrete is not the same service as a ground, sealed, flake-broadcast system.
Key takeaways
- Grinding creates the profile coatings need to stick
- Moisture and oil must be handled before color coats
- Cheap quotes often skip real prep
