Kerabond/Keralastic System is a high-performance, two-part system: Keralastic ™, a second-generation “flexible” acrylic latex additive, is used to enhance the performance of Kerabond ™, which is a premium-grade dry-set mortar. This system has exceptional bond strength, flexural strength, elongation and freeze/thaw durability. To ensure proper flexibility, always use a latex additive when applying a dry-set mortar over plywood or to set nonvitreous tiles.

Granirapid is the next generation of high-performance, flexible mortar systems. As the industry’s first and only fast-curing system geared for fast-track projects, it uses MAPEI’s unique High-Hydrated Cement Technology (HCT™). It develops high, early mechanical strength and can be specified for the same demanding applications as Keralastic™ ; however, Granirapid will cure considerably faster because its superior drying-out characteristics produce low residual moisture behind the tile after 24 hours.
Unlike old-generation “rapid sets,” Granirapid has a much better open and adjustability time while allowing application of grout in 3 to 4 hours. When used in conjunction with Ultracolor® grout (also with HCT technology), the installation will allow water immersion in a revolutionary 72 hours, as opposed to 28 days for traditional systems. Granirapid is a definite must when time is critical. Granirapid is formulated from a shrinkage-compensated technology that allows medium-bed, high-build capability for large-format tile.

Type 1 is a professional-grade, traditional, nonflammable, organic adhesive for setting impervious, vitreous, semivitreous and nonvitreous tile over gypsum drywall (walls only), cement board, exterior-grade plywood, concrete and masonry block. This adhesive is used for interior applications only. Type 1 meets or exceeds ANSI A136.1, Type 1 requirements.
