Merit Seal Polyurethane waterproofing chemical

Merit Seal Polyurethane Waterproofing Chemical is a high-performance, liquid-applied membrane specifically engineered to deliver long-lasting protection against water infiltration in critical areas of construction. This advanced polyurethane-based solution is ideal for roof waterproofing, basements, water tanks, bathrooms, balconies, terraces, and foundation walls, where a seamless, durable, and elastic waterproof layer is required. Unlike traditional bitumen-based waterproofing, Merit Seal forms a monolithic coating that adapts to structural movement, thermal expansion, and surface cracks, ensuring uninterrupted waterproofing even in harsh weather conditions.

application

Merit Seal is designed for both new construction and renovation projects. It provides excellent adhesion to concrete, cement plaster, brickwork, steel, and even old bitumen coatings, making it suitable for a wide range of surfaces. Its UV-resistant and weatherproof formulation protects exposed areas from degradation caused by sunlight and rain. Once cured, the membrane remains flexible, prevents water pooling, and resists peeling, blistering, and aging.

The application is simple and efficient—Merit Seal can be applied using a brush, roller, or spray machine, depending on site requirements. It penetrates deep into microcracks and forms a strong chemical bond with the substrate, offering high tensile strength and elongation properties. This makes it particularly effective for surfaces exposed to vibration, temperature changes, and foot traffic.
