MAPEI presents  Kerabond T, a premium-grade, non-sag, non-slump mortar for use in thin-set and medium-bed tile installations on both interior and exterior, residential and commercial floors and walls. When mixed with Keralastic, a second-generation “flexible” acrylic latex additive, the resulting system has exceptional bond strength, flexural strength, elongation characteristics and freeze/thaw durability, the company said.
