Dr. Fixit Fastflex Ultra — advanced cementitious waterproofing coating

Dr. Fixit Fastflex Ultra is a high-performance cementitious waterproofing coating from Pidilite Industries — an advanced, upgraded formulation of Fastflex engineered to deliver superior crack-bridging, flexibility, and waterproof protection for the most demanding applications.

Applied directly onto concrete and masonry surfaces, Fastflex Ultra forms a tough, seamless, and highly elastic waterproof membrane that flexes with the structure instead of cracking — providing reliable protection against roof waterproofing, terrace waterproofing, wall seepage, and bathroom waterproofing across residential, commercial, and industrial projects.

Its enhanced cementitious formulation offers greater flexibility, improved adhesion, and stronger resistance to water ingress compared to standard coatings — making it the premium choice waterproofing chemical for structures exposed to heavy rainfall, thermal movement, and continuous moisture. Backed by Dr. Fixit — one of India's most trusted names in waterproofing chemicals — Fastflex Ultra is the dependable construction chemical preferred by applicators and contractors for its proven long-term durability and consistent on-site performance.
