The present invention provides a dry mix of cement, sand, metakaolin in the amount of 5 wt % or less, based on total solids in the dry mix, and aluminum cement in a low amount (&#x2266;1 wt. %, based on total solids in the dry mix) useful as a tile grout, as well as uses thereof and to methods of using the same as a tile grout. The dry mix when made into a mortar exhibits excellent resistance to efflorescence as a tile grout.

Low efflorescence tile grout composition

Dry mix formulations containing a redispersible polymer powder (RDP) made of a low carboxylation, large particle size water-insoluble film-forming styrene butadiene polymer having at least one ethylenically unsaturated dicarboxylic acid monomer, and a high alumina content cement such as a calcium aluminate cement (CAC) or a calcium sulfoaluminate cement (CSA) provides cement compositions having unexpectedly superior water immersion shear strength and set time for a cement containing tile adhesive (CBTA or CTA), superior adhesion properties in water proofing mortars or mortar applications, and superior flexural and compressive strength in grout applications.
