Recognizing the need in the marketplace for a mortar that would deliver successful large-format tile installations, MAPEI has developed Kerabond T, a premium-grade, nonsag, nonslump mortar for use in thin-set and medium-bed tile installations on interior/exterior residential and commercial floors and walls. When mixed with water, Kerabond T acts as a medium-bed mortar meeting the ANSI A118.1 standard and ISO 13007 Classification C1T.
When mixed with Keralastic, a second-generation “flexible” acrylic latex additive from MAPEI, the resulting system has exceptional bond strength, flexural strength, elongation characteristics and freeze/thaw durability, meeting the ANSI A118.15 standard and ISO 13007 Classification C2ES2P2. The high-performance bond makes Kerabond T / Keralastic the best medium-bed mortar system for the most difficult tiles, substrates and conditions.
