Developed for use in 2-component flexible waterproofing cementitious membranes and can provide high flexibility at low temperature (-20°C). Flexible cementitious waterproofing membranes made with PRIMAL™ CM-500 Acrylic Dispersion are used for waterproofing of water tanks, water pipes and swimming pools, but also for basement walls, foundations and as waterproofing membrane on balconies or terraces. The high flexibility offers excellent crack bridging ability also at low temperatures. PRIMAL™ CM-500 Acrylic Dispersion could also be used for cementitious mortars applied in thin sections or as modifier of cementitious tile adhesives to provide a higher flexibility.
