Concrete Gum Shield (Shield 302) is a premium waterproofing basecoat engineered with pure acrylic latex and advanced nanotechnology to deliver long-lasting structural protection. Designed as an exterior waterproof undercoat, it creates a flexible, seamless membrane that protects buildings from moisture intrusion, water seepage, and environmental damage.

With exceptional crack-bridging capability up to 2mm, high tensile strength (1.4 MPa), and outstanding elongation properties (300%), Concrete Gum Shield ensures reliable performance even on substrates prone to movement. Its unique organic-inorganic nano-composite formulation enhances mechanical durability and extends the lifespan of concrete surfaces.

Perfect for residential, commercial, and industrial projects, Concrete Gum Shield also offers superior protection against carbonation and chloride penetration, helping prevent corrosion and ensuring long-term structural durability.
