Laticrete SpectraLock Grout with Microban
Laticrete has developed Laticrete SpectraLock Grout with Microban, an additive designed to lock in color and block out stains. The grout is engineered to be as easy to use as a Portland cement grout, but designed to perform at the optimal levels of an epoxy grout. Microban is formulated to inhibit stain-causing bacteria, mold and mildew.
