      Bostik PM Multi Purpose is "Polymer-Modified" Thin Set Mortar:

      Per KERDI Installation Instructions:
      1.The substrate must be clean, even, and load bearing. The thin-set mortar used for bonding KERDI must be appropriate for the substrate, and it must penetrate and engage the KERDI fleece. Generally, an "unmodified thin-set mortar" is used.
