Remove oil and contaminants, identify old paint or sealer, repair defects as specified, then mechanically profile the concrete. The exact profile should match the coating manufacturer’s requirements.
Inspect and prepare the slab
Remove oil and contaminants, identify old paint or sealer, repair defects as specified, then mechanically profile the concrete. The exact profile should match the coating manufacturer’s requirements.
Control dust and protect the site
Professional grinding uses appropriate dust extraction and protects adjacent rooms and stored items. Confirm what the crew will mask, move and clean before installation.
Avoid shortcuts
Coating over curing compounds, sealers, weak concrete or contamination can compromise adhesion. Acid etching is not automatically equivalent to mechanical preparation; follow the selected coating system’s data sheet.
Questions to ask Epotech
Ask what preparation method is included, how edges and corners are handled, how cracks are treated, and how the finished slab is checked before coating. Request those details in the written scope.
Common questions
Can a new garage slab skip grinding?
Not without checking its finish and the coating manufacturer’s prep requirement. New concrete can still have a dense or contaminated surface.
Will grinding remove every crack?
No. Grinding profiles the surface; cracks and moving joints need separate assessment and a specified repair approach.
