Yes, but the existing concrete must be properly evaluated and prepared first. Any existing coatings, sealers, or contaminants need to be removed to ensure proper adhesion.
Cracks get filled, uneven areas get leveled, and the surface gets mechanically abraded to create the right profile for bonding. Oil stains, efflorescence, and other issues get addressed before coating begins.
Some floors aren’t good candidates for epoxy – extremely damaged concrete, areas with ongoing moisture issues, or surfaces that can’t be properly prepared. A professional assessment determines whether your floor is suitable and what prep work is needed.
