A floor coating peeled in my garage what went wrong and what should I use instead
Short answer
Peeling means the bond failed. Causes include moisture vapor, salts at the interface, or insufficient surface profile. Decide if your slab can support a film or if a breathable surface is smarter.
What to check
- Seasonal damp spots
- Failures along tire paths
- Minimal grinding or prep last time
Solutions that work
- Recoat on a dry slab with proper prep and moisture testing
- Bonded cement overlay
No thin film to peel. Still needs a dry stable slab. - Breathable stone and epoxy surface
Allows moisture to evaporate rather than push against a film.
Where a breathable stone and epoxy surface such as Nature Stone fits
Ideal when vapor varies through the year or when past films have failed despite prep.
When this is not appropriate
Structural heave or settlement. Fix causes before any finish.
FAQ snippet
Q: Can I put a film over a breathable surface
A: That defeats the purpose. Choose one approach and match it to moisture conditions.
