Dimension™ RapidCure™ Glass-Filled, Pre-Mixed, Urethane Grout is a patented, reflective, water-based, urethane grout. Dimension™ RapidCure™ contains micro-glass beads and a translucent, urethane binder that both reflect light as well as allow it to pass through. This creates a variety of aesthetic effects in virtually all tile options available today. It may add an elegant sparkle and/or blend naturally with traditional tile and stone. It also creates a three dimensional effect within clear glass tile installations. Dimension™ RapidCure™ is approved for intermittent water exposure after only 3 days of cure.
