The National Tile Contractors Association, the largest tile contractors association in the world, is offering an updated version of its Reference Manual in a new CD-ROM format that will be available for all NTCA members on an annual basis to keep them up to date on important industry advances and installation materials.

Major revisions to the NTCA Reference Manual include information on installation, care and maintenance of natural stone tile installations, as well as two new documents addressing ceramic tile installation over poured gypsum underlayments, and the danger of using scribing felt as a crack isolation membrane.

Extra copies of the Manual can be purchased by Members in Good Standing for $50 each. They can be ordered online at www.tile-assn.com or by calling (601) 939-2071.
