ConCote 401 is a high-performance two-component waterproofing and protective coating system designed for long-term protection of concrete and masonry surfaces. It is engineered to create a dense, flexible, and durable barrier that prevents water ingress, carbonation, and surface deterioration in demanding construction environments. The system consists of two specially formulated components that work together to deliver superior performance. Component A is a liquid polymer-rich dispersion that enhances flexibility, adhesion, and water resistance. Component B is a carefully graded cementitious powder blend containing additives and fillers that provide strength, hardness, and durability. When combined, these two components form a smooth, brushable coating that chemically and mechanically bonds with concrete surfaces, resulting in a strong waterproof layer. This system is widely used in water-retaining structures, basements, retaining walls, tunnels, and other moisture-prone areas. It is suitable for both new construction and repair applications where reliable waterproofing and surface protection are essential. Once cured, it forms a tough yet flexible membrane that withstands environmental stress and prolongs the life of concrete structures. Two-component system: polymer liquid (flexibility & bonding) + cementitious powder (strength & durability) Provides excellent waterproofing and long-term surface protection Strong adhesion to concrete and masonry surfaces for reliable performance Prevents water penetration, carbonation, and surface degradation Ideal for basements, water tanks, tunnels, and retaining structures Flexible coating accommodates minor structural movement Suitable for both new construction and repair works Enhances durability and service life of concrete structures Resistant to moisture, weathering, and harsh environmental conditions Easy application using brush or roller for uniform coverage
