Protective coating for concrete is a chemical-resistant system applied to water tanks, industrial floors, swimming pools, and exposed structural concrete to shield the substrate from carbonation, chloride penetration, chemical attack, and moisture ingress that degrade concrete over its service life.

Uncoated concrete in water-retaining or chemically exposed environments deteriorates faster than the structure's design life — carbonation advances toward the reinforcement, chlorides accelerate corrosion, and chemical spills attack the cement matrix directly. A correctly specified protective coating stops that process at the surface, extending structural service life without the cost of repair or replacement.

ADT Industries stocks protective coatings for concrete and tanks from Sika, Fosroc, and Dr. Fixit — 46 products covering epoxy, cementitious, and water repellent grades for different exposure classes across India.
