grout joints in all dry tiled areas. Prism’s calcium aluminate formula delivers uniform, consistent color without shading or efflorescence. This lightweight, rapid-setting grout meets ANSI A118.7 and is walk- able in four hours. Prism creates dense, stain-resistant grout joints up to 1/2” and has a smooth con- sistency with excellent handling characteristics. All showers at the stadium, including the Falcons’ team show- er, were grouted with CEG-Lite™ 100% Solids Commercial Epoxy Grout. CEG-Lite provides chemi- cal and stain resistance with a fast cure time. The lightweight formula makes it easier to spread and clean than traditional epoxy grouts. Food preparation areas create a harsh environment for tile and grout, so kitchen floors received CEG- IG 100% Solids Industrial Grade Epoxy Grout, which delivers even higher chemical resistance. Movement joints and perimeter joints throughout all tile assem- blies were filled with Commercial 100% Silicone Sealant for perma- nent flexibility and protection. “Our installation crews liked working with all of the CUSTOM products,” said Michael Wadsworth, Field Superintendant with Spectra Contract Flooring.
