“NTCA Workshop,” and the NTCA Reference Manual was devel- oped, with the NTCA Technical Committee being re-organized into what it is today. In 1987, NTCA, along with the Ceramic Tile Distributors Association and the Tile Council of America formed the Tile Expo show, which turned into the International Tile and Stone Exposition, which is today, Coverings. Here are some pages right out of the per- sonal scrapbook of LATICRETE’s Henry Rothberg, showing a num- ber of STTMCA conventions in the 80s and a but- NTCA first logo as ATTMCA. The NTCA Reference Manual is a comprehensive culmination of knowledge, research and development of the Technical Committee mem- bers, ceramic tile contractors, distributors, manufacturers and others allied to the ceramic tile industry. In 1985, STTMCA changed its name to the Association of Tile, Terrazzo, Marble Contractors and Affiliates (ATTMCA) to signify it was a national association. The “National Tile Contractors Association (NTCA)” name was adopted in 1988. The ATTMCA Technical Committee work- ing on the Reference Manual in 1985. The STTMCA Annual Convention in 1983. In the 80s, the educational road show was officially named the “NTCA Workshop.” Celebrating 70 years TileLetter | September 2017 83
