Garage Floor Prep in Boise: Why Grinding Comes First
Gloss fails when bond fails. Most peeling floors we see weren’t “bad epoxy” — they were paint or resin on dusty, sealed, or damp concrete. Here’s what real prep looks like before we talk color chips.
Process
What “prep” means on a Treasure Valley slab
1. Diagnose the surface
Photos of peeling paint, oil shadows, and hairline cracks help. Builder sealers are common on newer Meridian and Eagle slabs — they must come off or the next coating peels with them.
2. Mechanical profile
Diamond grinding opens the concrete so resin can key into it. Sweeping and etching alone rarely match a proper grind on garage floors that see hot tires.
3. Repairs & moisture
Crack fill, joint work, and moisture checks when the slab shows dampness or known irrigation splash. Coating over active moisture is how glossy floors blister.
4. Then chemistry
Only after the slab is ready do we choose epoxy vs polyaspartic builds and flake blends. Prep is the unglamorous half of a floor that still looks good in year five.
Boise-specific prep gotchas
- Winter melt grit — sand and de-icer leave residues; cleaning alone isn’t a substitute for grinding.
- Shop oil history — deep oil needs solvent and mechanical work, not a coat of paint.
- New construction sealer — many subdivision slabs arrive sealed; assume grind-off unless tested otherwise.
- Cool shoulder-season installs — slab and air temps affect both grind dust control and cure — we plan windows accordingly.
