Two-component, super-low-viscosity, deep-penetrating E-Pro Seal SLV epoxy sealer is designed to repair concrete cracks and to protect concrete from potential deterioration. It penetrates into fine cracks and pores to seal the surface and prevent the migration of moisture, chlorides, and other harmful contaminants from getting into the concrete.
