Why does marble etch, and how do you prevent it?
Marble is calcium carbonate. Anything acidic, like lemon, vinegar, wine, or tomato sauce, reacts with it and leaves a dull spot. That is an etch, not a stain, and no sealer prevents it because a sealer only slows liquids from soaking in. The acid still touches the stone.
So what does it look like after you protect it? Exactly the same. StoneGuard is a protective film that keeps acids off the marble entirely. Whether you have a polished look or a matte look, we have a film for it. StoneGuard Clear keeps the shine on polished stone, and StoneGuard Satin matches the soft finish of honed stone. Either way the finish underneath stays exactly as it was installed. The only difference is that the spills in this video wipe away instead of leaving a mark.
