This integrated system provides a high-performance solution for renovating interior walls directly over ceramic and porcelain surfaces. It begins with a specialized scratch coat that ensures excellent adhesion to tile substrates. This is followed by a super-fine, shrinkage-free leveling compound that delivers an ultra-smooth surface while effectively concealing irregularities. A penetrating sealer is then applied to enhance substrate integrity, providing alkaline resistance and a waterproof barrier. The system is completed with a high-adhesion, carbonation-resistant acrylic topcoat that protects against water ingress, conceals surface defects, and delivers a durable, aesthetically refined finish suitable for long-term interior applications.
