Feature: MAPEI goes to Yale School of Management Edward P. Evans Hall is home to state-of-the-art classrooms, faculty offices, academic centers, and student and meeting spaces organized around an enclosed courtyard. The design is intended to create a teach- ing and learning environment that will support the school’s integrated MBA curriculum and connect the Yale School of Management (SOM) community. MAPEI products at work on the jobsite Various large-format tiles from England were used throughout this proj- ect. Mapeguard 2 was used in many of the large-format tile areas to protect it from crack- ing. Tile sizes include 24” x 24” (61 x 61 cm), 18” x 18” (46 x 46 cm), 12” x 18” (30 x 46 cm) and 12” x 24” (30 x 61 cm). Smaller sizes were also used on walls and floors in the bathroom installations. Atlantic Masonry does the majority of the tile installation work at Yale University, and they were called in to work with general contractor Dimeo Construction on this project. The crews installed quarry tile in the kitchens, porcelain tile from Daltile in the bathrooms, and a large-format English por- celain tile from Royal Mosa in the first-floor lobby surround- ing the courtyard. The work began with the application of a pre-screed composed of sand and cement fortified with Planicrete AC. This mixture was used in a mud-set application to cover the tubing of an underfloor radiant-heating system. The most important aspect of this Ultraflex LFT, Ultracolor Plus with the Mapesil 100% silicone sealant were also used for the quarry tiles in the kitchens and the black-and- white porcelain tiles in the bathrooms. Wall tiles in bathrooms were grouted with Keracolor U unsanded grout. 32 TileLetter | 2019
