ROBUST RC-7 SEAL is a superior-quality, elastomeric waterproofing and sealing compound that has been specially engineered for long-term protection of a wide range of horizontal and vertical surfaces. It is ideal for use on concrete roofs, terraces, balconies, parapet walls, podiums, and exterior vertical surfaces, as well as water tanks (from the outside), basements, and other areas that are frequently exposed to moisture or harsh weather conditions. Formulated using advanced acrylic polymer chemistry, RC-7 SEAL creates a tough yet highly flexible waterproofing membrane that adheres strongly to cementitious substrates, effectively bridging hairline cracks and preventing the ingress of water, moisture, and atmospheric contaminants. Its high elasticity ensures it can accommodate minor substrate movement and thermal expansion or contraction without losing adhesion or forming cracks, thereby providing a durable and long-lasting barrier against water damage.
One of the key advantages of ROBUST RC-7 SEAL is its excellent resistance to UV rays, making it suitable for exposed surfaces that endure prolonged sunlight. The coating does not become brittle or degrade over time, which helps to extend the life of the structure and reduce long-term maintenance costs. Additionally, the product exhibits excellent resistance to fungal and algal growth, making it a hygienic and aesthetic choice for damp-prone areas. The breathable nature of RC-7 SEAL allows trapped moisture within the substrate to escape without compromising the waterproofing performance, preventing issues like blistering or peeling over time.
ROBUST RC-7 SEAL is easy to apply with a brush, roller, or airless spray, and it dries quickly to form a seamless, joint-free film that covers even uneven or irregular surfaces. It is available in multiple colors, which adds to its aesthetic appeal and makes it suitable as a final coat in many applications. The product is non-toxic, environmentally friendly, and safe to use in both residential and commercial settings. It also provides a degree of thermal insulation, helping to reduce heat absorption in concrete roofs and thereby improving energy efficiency in buildings.
