Customer Questions & Answers

Do you have to use an admix

In using the standard thin set and you are laying 16X16 on concrete floors do you have to use an admix, if you do not will the tile be more apt to come up? I have a tile guy wanting to just use the thinset without an additive.
Asked by: Flacarperson
Standard thinset mortars achieve stronger bond when mixed with admix. For installing 16"x16" a medium bed mortar such as Marble Granite & Travertine Mortar should be used. If you need further assistance contact our installation division at 800.282.8786
