Abstract
Grout compositions having a binder including water-borne polyurethane and a filler are described herein. An accelerator component is provided to control the rate of grout curing, thereby decreasing the time required between grout application and grout use. This result is achieved while providing sufficient time for grout application. Grout may be light-transmissive and include light-transmissive binder and filler.
