This internal wall coating system is engineered to deliver superior durability, strong adhesion, and a high-quality aesthetic finish. It includes an optional cementitious waterproofing scratch coat to enhance bonding on smooth or tiled substrates, followed by a super-fine levelling mortar that ensures an ultra-smooth, shrinkage-free surface. The system is completed with a solvent-free, flexible epoxy coating that provides excellent chemical resistance, high mechanical strength, and long-term protection for concrete and steel surfaces in demanding interior environments.
