How to Prepare Your Concrete for Epoxy Resin Application
Step 1: Clean Thoroughly
Remove dirt, oil, and mildew. Use a pressure washer or a mixture of water and mild detergent.
Step 2: Repair Cracks and Spikes
Fill cracks with concrete patch or epoxy patch kit. Allow to cure fully before proceeding.
Step 3: Etch the Surface
Etching with muriatic acid or a commercial etching solution creates micro‑pitting for better adhesion.
Step 4: Ensure Proper Moisture Levels
Use a moisture meter. Concrete should be below 1.0% moisture content; otherwise, seal the surface before applying epoxy.
Step 5: Protect Surrounding Areas
Cover plants, rugs, and nearby surfaces to prevent accidental spills.
Follow these steps closely, and you’ll set the stage for a durable epoxy finish that lasts years.
