Thin-Set Mortar Admix

A liquid polymer designed to be used in place of water to increase performance of cement mortar beds, non-modified, thin-set mortars and cement-based grouts. It improves working characteristics and performance of cement-based mixes to boost water resistance, shock resistance and freeze-thaw capabilities for tile, stone or masonry installations. Increases performance of non-modified thin-set mortars for setting dense tile and setting over hard-to-bond surfaces. Thin-Set Mortar Admix can be used with non-modified, thin-set mortars such as, CustomBlend® Thin-Set Mortar and Uncoupling Mat Mortar. It can also be used with Saltillo Grout Mix.
