Proper prep — the step nobody should skip
Coatings fail because of prep, not product. Resin4U runs diamond grinders with HEPA dust collection to strip old paint, glue, mastic, and sealer then open the slab to the concrete surface profile the coating manufacturer requires. We also grind as a standalone service for contractors and homeowners doing their own install.
We test what's on the slab so we bring the right tooling.
Walk-behind grinders take the floor down to clean, open concrete.
Hand grinders finish perimeters, corners, and around obstacles.
The slab is vacuumed and the profile is checked before anything is applied.
