Can I use an Epoxy Sealer on Stone? Can an epoxy sealer be put on sandstone? Or, should I stay with say "StoneTech Bullet Proof Sealer"? Application: countertops. ANSWER ANSWER - It is not recommended to put an epoxy coating over the surface of any stone. First because it traps in moisture and stone needs to breath to avoid deterioration.
