Granirapid is the industry’s first and most flexible, high-performance, fast-curing mortar system geared for fast-track projects. It develops high, early mechanical strength and can be specified for the most demanding tile applications. Thanks to MAPEI’s High-Hydrated Cement Technology (HCT), Granirapid offers superior drying-out characteristics for quick curing and does not contribute to efflorescence. When installed in conjunction with Ultracolor Plus FA grout, Granirapid will allow water submersion in only 72 hours. Must be used with Granirapid Additive/Liquid
