Gator Dust Bond, like its big brother, Super Sand bond, is apolymeric jointing sand that uses the bonding properties of polymers. The main difference is in the size of the primary materials, stone dust versus sand. Gator dust bond base material is stone dust, much finer than regular jointing sand. It is designed to stabilize wider paver joints than polymeric sand. Depending on the paving stone design or job specifications, Gator Dust polymeric stone dust will be your very best choice to secure pavers in place for years, and prevent sprouting or soil erosion.
