Because concrete countertops are porous, they tend to stain relatively easily. Many homeowners choose to apply an epoxy coating to their concrete countertops to protect them from stains and everyday duress. Epoxy coatings also serve to enhance the beauty of an ordinary countertop by providing an attractive sheen. Before you apply epoxy to your concrete countertops you need to understand the proper preparation and application procedures or you may end up with disappointing results.
Cover flooring with fabric drop cloths.
Apply a concrete primer to the concrete using a latex paintbrush. Allow the primer to dry for two full hours.
Clean the brush with water.
Pour the resin into a 2-gallon painter's pot. Stir for two minutes using a wooden stir stick.
Pour the mixture into a different, clean 2-gallon painter's pot. Stir the mixture for another five minutes, then pour the mixture directly onto the concrete countertop.
Spread the epoxy using a new, clean 4-inch latex paintbrush. Ensure that there are no dry spots on the countertop. Brush slowly around the edges to prevent the epoxy from running over.
Break surface bubbles by heating them with a heat gun. Smooth the indentation left after they pop with a porcupine roller.
