Concrete Preparation Before Epoxy Coating
Preparation is often the difference between a coating that bonds and one that peels.
Remove weak material
Existing sealers, laitance, loose concrete and contamination can block adhesion. Use a preparation method suited to the slab and specified surface profile.
Control dust and defects
Use suitable dust extraction and protective equipment. Repair cracks and spalls with compatible materials and respect repair cure requirements.
Verify before coating
Check cleanliness, profile, moisture and ambient conditions. A visually clean slab may still be unsuitable.
