Rapid-Setting, All-in-One Grout Replacement for Sanded and Unsanded Grouts. Ultracolor Plus FA with DropEffect technology is an ultra premium, fine-aggregate, fast-setting, polymer-modified, color-consistent, nonshrinking, efflorescence-free grout. DropEffect reduces surface absorption to help repel water, dirt and grime from penetrating grout joints. Ultracolor Plus FA is specially formulated with MAPEIs High-Hydrated Cement Technology (HCT) to eliminate the common problems related to Portland-cement grout, such as color consistency and efflorescence. Along with offering higher polymer content, HCT reduces absorption and increases stain resistance when compared with standard-performance cement grouts. Ultracolor Plus FA is formulated with 10 percent recycled content and meets the ANSI A138.1 specification for Green Squared certification.
