What does sealing or impregnating stone really mean?
In the stone industry, sealing and impregnating are often confused. The main objective of an impregnator is to protect the inside of natural stone from staining. Impregnators help prevent fluids from penetrating into the stone surface, but they do nothing to protect the top surface of the stone. They do not prevent traffic patterns, and they will not prevent etching from acid spills on marble. An impregnator will keep the acid out of the stone but not off the top surface.
