UltraTech Seal & Dry Hi-Flex
Two-component cementitious elastomeric waterproof coating for large or high-risk areas
Product Overview
UltraTech Seal & Dry Hi-Flex is a two-component, cement-based, acrylic-emulsion elastomeric waterproof coating engineered for demanding positive-side waterproofing. Blending a polymer liquid with a cementitious powder produces a highly elastic membrane that achieves 100% elongation at a tensile force of 50 kg/cm² and withstands water pressure up to 7 bar at 1 mm dry film thickness. This exceptional crack-bridging and pressure resistance makes it suited to large and high-risk areas such as swimming pools, sump tanks and exterior walls. Non-toxic and breathable, it bonds to concrete, natural stone, marble and granite. Part of the UltraTech Building Products range and supplied through Space Arc Engineering, an Authorized Project Distributor in India, Hi-Flex is the premium choice for areas exceeding 10,000 sq ft where long-term waterproofing performance is essential.
