material measuring 2.5’ x 5’ was mechanical- ly anchored on lobby walls and 20 stories of tower lobby floors were set with the quartzite in a 24” x 24” format. “ProLite is our num- ber one choice,” said Jim Lunn, foreman at Carnevale and Lohr. “The guys in the field really like using it, espe- cially for walls. The workability without sag is phenomenal. The pot life of ProLite is great and being lightweight is also a big plus,” he added. Protecting the tile assemblies Core restrooms on all floors and the parking garage were treated with RedGard® Waterproofing and Crack Prevention Membrane. A ready-to-use elastomeric mem- brane that creates a continuous waterproof barrier, RedGard has outstanding adhesion and bonds directly to a variety of drain assem- blies. RedGard exceeds both ANSI A118.10 and A118.12 for dual protection against moisture intru- sion and in-plane crack transmis- sion. Third-party laboratory testing has shown that RedGard outper- forms other liquid-applied mem- branes for key perfor- mance attributes as well as actual coverage rate. After application of RedGard, bathroom floors were set with 12” x 12” Spec Ceramics Space Taupe matte tile. The porcelain tile installed on the walls was 12” x 24” Pure White matte supplied by Emser. Soft joints at changes of plane were filled with PolyBlend® Ceramic Tile Feature: CUSTOM System selected in Orange County ProLite® Premium Large Format Tile Mortar was selected to install all porcelain tile and stone materials throughout the project. Fast curing Prism® Ultimate Performance Grout was installed in shades that complement the materials for a modern, monolithic look. 44 TileLetter | June 2018
