Concrete preparation for a coating may include diamond grinding, cleaning contaminants, removing old coatings, repairing cracks or spalls, and evaluating moisture. The exact scope should follow the slab’s condition instead of being assumed from a square-foot price.
What a careful evaluation should cover
When comparing quotes, ask what happens if the crew finds old sealer, adhesive, soft concrete, or deeper damage after preparation begins.
- Concrete condition, contamination, and any existing coating
- Cracks, spalls, joints, and signs of moisture
- Traffic, sunlight, chemical exposure, and the intended finish
- Preparation method, repair scope, and realistic return-to-service timing
Questions to put in writing
Ask who is doing the preparation, whether diamond grinding is included, what repair work is assumed, how change conditions are handled, and what the final system layers are. A clear scope is more useful than a broad “lifetime” claim with no detail behind it.
