“How do I prepare my concrete floor for epoxy coating?”

Due to its ease of application and cost-effective price point, epoxy is a popular covering for residential and commercial concrete flooring.

Proper concrete floor preparation for epoxy painting is crucial to achieving long-lasting results. For epoxy coatings, the licensed and certified contractors at Anderson Painting recommend Penntek solid-color epoxy for concrete floors. This specially engineered system includes a low viscosity two-part epoxy primer, a high-build epoxy color coat, and a protective polyurea or aliphatic urethane topcoat. Together, these layers fix the problems associated with lower-quality epoxies, providing superior impact resistance and dependability at an affordable price.

The Penntek epoxy system offers:

  • Custom color matching

  • Chemical and abrasion resistance

  • Long-term durability and adhesion

  • Pre-tinted color for consistent coverage

  • Quick cure times

  • Low odor installations

How Do You Prepare a Concrete Floor for Epoxy Coating?

Follow these five steps:

  1. Clean and degrease the floor. Sweep or vacuum to remove dirt and debris, then apply a concrete degreaser to remove oil and other contaminants that can prevent adhesion.

  2. Repair cracks and surface damage. Use an angular grinder to clean cracks and remove loose dirt. Fill the cracks with a two-part epoxy patching compound and grind to a smooth, level surface once cured.

  3. Profile the surface. Use a diamond grinder or shot blaster to remove any existing sealers or coatings and create a rough surface that helps theepoxy for concrete floors bond properly. Sweep and vacuum again to maintain a clean surface.

  4. Check for moisture. Perform a moisture test to confirm the surface is completely dry before applying the coating.

  5. Apply primer and coating. Follow the manufacturer’s directions to apply a thin, moisture-sealing layer of epoxy primer. Once cured, apply the Penntek epoxy floor paint for concrete coating system following the product’s directions.
