RC-7 SEAL is a premium-grade, multi-purpose waterproofing and protective sealing chemical specially formulated to provide long-lasting resistance against water penetration, moisture absorption, chemical attack, and surface deterioration. It is developed using advanced silane/siloxane and modified polymer technology, which allows it to deeply penetrate into the pores and capillaries of concrete, mortar, plaster, stone, and other masonry substrates. Once applied, RC-7 SEAL forms an invisible yet highly effective water-repellent barrier that chemically bonds with the substrate. Unlike surface coatings that can peel or wear off over time, RC-7 SEAL works internally, offering a breathable treatment that allows trapped moisture or vapor within the structure to escape, thereby preventing issues like blistering, peeling, or efflorescence.
RC-7 SEAL is highly versatile and suitable for both new construction and remedial applications. It is widely used for waterproofing rooftops, terraces, podiums, water tanks (both overhead and underground), basement walls, swimming pools, bathrooms, balconies, exterior facades, and retaining walls. Its exceptional hydrophobic properties prevent rainwater, seepage, or dampness from penetrating through the surface, while still maintaining the natural appearance and finish of the material. Moreover, RC-7 SEAL enhances the structural durability of the building by shielding it from damaging elements such as UV rays, freeze-thaw cycles, carbonation, chloride ion ingress, and airborne pollutants.
What sets RC-7 SEAL apart from traditional waterproofing products is its ability to perform under extreme weather conditions and in a variety of environmental settings—be it humid coastal zones, high-rainfall areas, or dry, dusty regions. It also exhibits strong resistance to alkalis, mild acids, salts, and microbial growth, making it suitable for industrial zones and chemical-prone environments. The product is easy to apply using a brush, roller, or spray equipment, and typically requires minimal surface preparation, making it an ideal choice for contractors, engineers, and homeowners seeking cost-effective and reliable waterproofing solutions.
In addition to its technical performance, RC-7 SEAL is environmentally safe, non-toxic, and free from harmful solvents or volatile organic compounds (VOCs), which means it can be safely used in sensitive areas like drinking water tanks or food processing zones. By significantly reducing water absorption, RC-7 SEAL helps prevent corrosion of embedded steel reinforcement, surface cracks, algae and fungus growth, and long-term degradation.
