Feature: MAPEI goes to Yale School of Management step was to ensure that the installers did not break any of the heating tubes; so, when the installers were pre-screeding, they continually tested the tubing to make sure nothing was damaged. Over top of the pre-screed, the Atlantic Masonry crews applied Mapeguard 2 pre- mium crack-isolation and sound-reduction membrane to protect the large-format tiles from cracking – “issues that are becom- ing too common with the increase in tile dimensions in educational facilities, such as thisYale project, ” said Atlantic Masonry Project Manager Mike Coassin. Atlantic Masonry prefers Mapeguard 2 because it is thicker and denser than competitive products, and the installers think it does a better job in the long run. The English tiles from Royal Mosa, predominantly the 12” x 24” (30 x 61 cm) size, were installed in the lobby with Ultraflex LFT and grouted with Ultracolor Plus. Mapesil 100% silicone sealant was used at the soft joints in the lobby – approximately every 15 to 20 ft. (4,57 to 6,10 m). These setting materials were also used for the quarry tiles in the kitchens and the black-and-white porcelain tiles in the bathrooms. The joints in the wall tiles of the bathrooms were grouted with Keracolor U unsanded grout. The bathrooms were also waterproofed with Mapelastic AquaDefense. Coassin commented on the project: “This was a pretty standard project for Atlantic Masonry,” Coassin said. “We have installed tile in most of the reno- vated and new buildings on the Yale campus, and we are very satisfied with the way the MAPEI products work for us.” TECHNICAL DATA: Project Category: Institutional - University MAPEI Sales Rep: Mike Shay Project Owner: Yale University MAPEI Distributor: Daltile – North Haven, Conn.
