Epoxy Garage Floors — Huron, Tuscola & Sanilac Counties
Block building coatings fill, level, and protect concrete masonry unit (CMU) walls — interior or exterior — typically with a block filler followed by an elastomeric or acrylic topcoat.
Why epoxy garage floors projects fail
The failure modes we see most often across the Thumb — and how we prevent each one on every project.
- Skipping block filler — paint sinks into the open pores, looks blotchy and burns through coverage rates.
- Wrong filler — water-based filler in a wet basement = bubbling.
- Painting over efflorescence — coating peels off in sheets the next humid season.
Surface preparation we perform
Prep is the largest single driver of coating lifespan. Every step below is written into every estimate.
- Power wash and scrape any failed coating
- Treat efflorescence with phosphoric acid wash
- Apply block filler with a 1.25" nap roller, work into pores
- Topcoat after filler fully cures (24-48 hr)
