Every successful concrete coating job starts with surface preparation.
In North Carolina’s climate, applying an overlay or epoxy over unverified, soft, or compromised concrete is a recipe for costly callbacks. Here is why testing slab hardness before you pour or roll is non-negotiable, and how to do it right.
1. Concrete Hardness Determines Bond Strength.
An epoxy or overlay is only as strong as the concrete layer it bonds to.
2. The North Carolina Factor: Humidity, Moisture, and Weather.
North Carolina contractors deal with distinct environmental conditions that impact concrete wear and curing, including high humidity, red clay and fine aggregates, and freeze-thaw cycles.
3. How to Test Concrete Hardness on the Job-site.
You can perform quick, accurate tests directly on-site using The Mohs Hardness Test.
