Flex set flexible latex-Portland cement mortar is a high-strength, all purpose bonding mortar formulated for the installation of ceramic, mosaic, glass, quarry tiles and dimension stone (absorptive, semi-vitreous and vitreous) tiles. It may be used for either floors or walls in both interior or exterior applications where a flexible latex-Portland cement mortar is required. Redispersible powder additives and plasticizers are used to improve flexibility, adhesion, provide greater bond strength and resistance to impact and shock. These additives allow for some latitude in time, working conditions and temperature. Flex Set will reduce tile cracking when used on substrates subject to minor deflection. Flex Set may be used to bridge-over existing in-plane cracks up to 1/16” without the need for additional surface preparation.
