Concrete floors are usually so durable that users pay them scant attention. But when exposed to aggressive chemicals, floors can deteriorate rapidly. If left unprotected, damaged floors can interfere with facility operation and create safety hazards for workers.

A variety of surface protection options are available that can prevent deterioration of concrete floors in even the most aggressive environments. In addition to increasing the chemical resistance of concrete, many coatings and overlays improve other important properties such as abrasion and impact resistance. This article discusses nine generic types of chemical-resistant concrete protection: epoxies, epoxy novolacs, urethanes, methyl methacrylates, polyesters, vinyl esters, potassium silicates, acid brick and sulfur concrete.
