GATOR DUST is a unique mixture of polymer binders and calibrated stone available in Sahara Beige and Stone Grey. Once GATOR DUST sets, it becomes very firm and locks between the wet cast or natural stone joints while still retaining flexibility and providing a long lasting, durable jointing material. GATOR DUST is recommended for a variety of uses including pool decks, patios, footpaths, and any other pedestrian applications.
