Why Garage Floors Peel & How to Fix Them | East TN Guide
Why Your Garage Floor Peels (And How to Fix It Permanently)
Many homeowners call us frustrated after their DIY epoxy kit or “budget installer” job starts peeling within months.
Here’s the real reason this happens — and how a true concrete coating professional prevents it.
1. The Floor Wasn’t Properly Prepared
Most peeling issues come down to one thing:
The concrete wasn’t ground correctly.
Budget installers may use acid etching — which creates an uneven, unreliable surface.
We use industrial concrete grinders to create the perfect bonding profile.
That’s why our floors don’t peel.
2. Moisture Wasn’t Tested
East Tennessee concrete often contains hidden moisture.
If it’s not checked with a moisture meter (we check every job), the coating can bubble or lift.
High moisture? We apply a moisture vapor barrier so the system lasts.
3. Wrong Coating Type Used
Most peeling floors are epoxy — especially DIY kits.
Epoxy has weak adhesion and low UV stability.
If you want a floor that stays strong, you need a polyaspartic floor coating engineered for long-term performance.
4. Heat from Tires Lifted the Coating
Hot-tire pickup destroys many garage floors.
Floor Shield’s polyaspartic system resists heat better than epoxy or polyurea, keeping your floor intact.
How to Fix It for Good
If you already have peeling, cracked, or yellowing floors, we can repair the concrete and install a strong, UV-stable polyaspartic coating that actually lasts.
