Introducing StainZero — crystal-clear protection for marble and other acid-sensitive stone

The Problem

You Love Your Marble.
Lemons, Wine and Vinegar Don't.

Marble is one of the most beautiful surfaces you can bring into your home, and one of the most delicate. A slice of lemon, a splash of wine, a drip of tomato sauce or the wrong cleaner can leave dull, permanent etch marks in minutes. Traditional sealers help slow stains, but they don't stop etching.

So you end up with coasters everywhere, constant worry and countertops you're afraid to use.

It doesn't have to be that way.

Anti-Etch 101

What Is an Anti-Etch Coating, and How Do You Stainproof Marble Countertops?

An anti-etch coating (sometimes written anti etch or antietch) is a protective treatment applied to acid-sensitive stone such as marble, limestone, travertine and onyx. Etching happens when acids — lemon juice, vinegar, wine, coffee, tomato sauce or the wrong household cleaner — react with the calcium in the stone and leave a dull, permanent mark. Traditional marble sealers slow staining, but they do not stop etching. A true anti-etch coating shields the surface so acids can't react with the stone in the first place. See how anti-etch coating compares to a marble sealer.

If you're looking for how to stainproof marble countertops, this is the difference that matters. StainZero is a crystal-clear anti-etch coating that keeps your marble countertops, kitchen islands, bar tops, bathroom vanities and tables free of etch marks and stains. It preserves the stone's natural veining and character, so your marble still looks like marble — just protected. Applied only by a StainZero Certified Applicator, and backed by a Lifetime Limited Warranty against stains and etch marks.
