I am in the middle of a master bath rehab. The tile sub that did this job, I just found out is not licensed! The first red flag was that he tiled the tub surround on drywall NOT CBU (which I think is IRC code). Also, I went back to the General Contractor (I checked his license before I signed the contract, so he is licensed) and told him that the tiles are not lined up properly and the tub surround issue needed fixing. I became suspicious of the tile job in general (doesn't look right), so I checked out the thin set product he used for the subway tile job in my shower. Then I called the product maker. Well low and behold the tile is attached to the CBU with the wrong product. NOW WHAT DO I DO? Does the whole shower need to be dismantled and rebuilt?

Hi Chris,


Thanks for calling today. Per our discussion, the TEC Skill Set Natural Stone and Large Tile Mortar is only meant to install tiles 16" x 16" and larger on floors only. It is not meant for tile smaller than 16" x 16" and it is not designed for vertical surfaces. This mortar provides good coverage and bond to large and heavy tile on a horizontal plane only. I've attached a copy of the Product Data Sheet which states this information. Here's a link to the information on the website: http://www.tecskillset.com/tile-installation-products/set-the-tile/floor-tile-mortar.html#.Vds1pPlVhBc

For vertical installations with natural stone or large tile, or even small porcelain or ceramic tile, the best choice in the TEC Skill Set line is TotalFlex Universal Mortar. The information on that product can be found here: http://www.tecskillset.com/tile-installation-products/set-the-tile/tile-mortar.html#.Vds7NflVhBc


Thanks,
