Training Director Mark Heinlein and NTCA Trainer Randy Fleming addressed this situation with the member via phone. These aspects of the job were discussed with the member. 

  • Temperature of setting materials, tile, substrate and techniques to keep them within a proper working temperature range.
  • Scheduling work flow to take advantage of time of day temperature cycles and movement of the sun/shade.
  • Techniques to shade the substrate and installation work area.
  • Techniques to ensure cool water for mixing.
  • Selecting adhesives for an extended open time/long pot life.
  • Mixing location of adhesive to aid in pot life.
  • Applying a membrane to prevent the dry substrate from drawing the water of the adhesive.
  • Working with the preferred setting material manufacturer as a partner to select the correct adhesive and membrane and to understand proper mixing, application and open time.
  • Preparing the substrate to ensure all bond breakers/curing compounds are removed and to create the required concrete surface profile for bonding.
  • Identifying the appropriate TCNA Handbook method to be used (likely W202E) and the installation standards and material specifications it references.
  • Requiring the specifier to provide drawings/details for installation/location/materials for movement joints as described by EJ171.
