Cemseal Black Membrane is a PU based, cold-applied, ready-to-use liquid
waterproofing membrane made from a special blend of high-quality resins and
rubber. It is reinforced with water-repelling fillers, mineral stabilizers, and gelling
agents to create a highly flexible and durable coating. It is ideal for protecting
concrete and masonry surfaces such as walls, bathrooms, basements, bridges,
terraces, decks, and even metal surfaces. It can be used in new construction or
applied over existing structures to prevent water penetration.
• Easily adapts to uneven surfaces, forming a continuous, watertight barrier.
• Forms a highly elastic, rubber-like membrane that can withstand building movements such as expansion and contraction without cracking.
• Excellent resistance to UV rays, ozone, and oxidation thanks to advanced additives—offering longer life than standard asphalt coatings.
• Strong adhesion and wetting properties help create a long-lasting bond that resists peeling, flaking, or separation.
• Single-component, cold-applied product—no mixing or heating required, reducing labor and simplifying application
