Laticrete’s Tri-Lite is a lightweight, high-performance, tri-purpose mortar designed for large and heavy tile, thin-bed and wall installations. A 30 lb. bag of Tri-Lite provides the same coverage as a 50 lb. bag of traditional mortar, making it both easier to transport and easier to trowel, the company said. Tri-Lite can be built up to 3/4” (19 mm) thick without shrinkage, Laticrete noted.
