Quick answer: Surface preparation is the work that helps epoxy bond to concrete. It may include grinding, shot blasting, old coating removal, glue removal, cleaning, crack repair, and moisture evaluation.
Most commercial coating problems start before the coating is installed. If the Phoenix slab is contaminated, too smooth, cracked, dusty, or covered in old adhesive, the new floor system may not bond the way it should.
Surface prep can include
- Concrete grinding and surface profiling
- Removal of old epoxy, sealers, VCT adhesive, carpet glue, tile residue, and thinset
- Crack and spall repair planning
- Cleaning oils, dust, grease, and contaminants
- Substrate readiness review before coating
