gridded the floor in 4-ft. sections, and placed a pin at every intersection of chalk lines. Pins were trimmed to the lowest level height measurement, and a special solvent-free, acrylic primer was poured, followed by a self-leveling underlayment to the determined height, assuring a “dead level and perfectly flat floor.” The crew – Nolen, along with his son Caleb Nolen and Reece Stepler – used expansion foam around the perimeter of the room, and applied three coats of a topical crack-iso- lation membrane. Only then were the 30” x 30” tiles installed with a multi-use, polymer-fortified adhe- sive mortar to “achieve a flawless tile assembly that will stand the test of time,” Nolen said. Erin Albrecht, M.Ed., J&R Tile “We are especially proud” of this design build at Trinity University that features Florida Tile Level 10 HDP-High Definition Porcelain 18” x 36” in Pearl Atrium installed with a 1/8” joint, said Eric Albrecht, M.Ed., of J&R Tile. The project was a total $8 million renovation. J&R saved the client “loads of money on an epoxy grout spec, and the [originally] speced tile was thicker, smaller and more expensive,” she added. J&R’s Adam Arrellano, who holds CTI and Advanced Certifications for Tile Installers credentials, was the working foreman on this project and also was responsible for the layout and design. He centered Planitop® 330 Fast is a quick- setting, polymer-modified, fiber- reinforced cementitious rendering, patching and level- ing mortar. It can be applied from 1/8” to 1-1/4” (3 mm to 3,2 cm) thickness in a single coat. Planitop 330 Fast can be used for ramping, smoothing and leveling clean, interior and exterior con- crete and screed floor substrates to prepare them for installing ceram- ic, stone or waterproofing systems. Eliminating the need for a latex additive, Planitop 330 Fast requires only mixing with water to produce a non-sagging mortar that bonds directly to the substrate, readying it for tile installation in as little as 90 minutes. Because Planitop 330 Fast provides a superior flat finish, it produces an excellent substrate for the installation of thin tile and gauged porcelain tile panels. Planitop 330 Fast has the added environmental benefit of having been verified “Red List Free” per the most current Red List on the Living Building Challenge website. www.mapei.us.
