GranSeal is a one-time application sealer for granite and stone products with a 15-year limited warranty. Standard sealers offer little or no warranty against stains and have a shorter protection period than GranSeal.  What makes GranSeal different is that it’s an impregnator type of sealer.  Impregnator sealers have nano-sized solvents and protective agents which allow the chemical to penetrate deeper into the stone and therefore provide longer duration of protection.
