Stainproof Sealer & Anti-Etch Applicator

No. StainZero is not a do-it-yourself product. It is installed only by a factory-trained StainZero Certified Applicator, because proper stone preparation and application are what make the protection and the Lifetime Limited Warranty possible. Request an applicator through this page and one in your area will contact you.

Your certified applicator first restores the stone — removing existing etch marks and most stains — then cleans and prepares the surface so the coating bonds evenly. They then professionally apply the StainZero anti-etch and stainproof system and register your Lifetime Limited Warranty. Most projects are completed in one to two days.

StainZero protects natural stone countertops: kitchen countertops, islands, bar tops, bathroom vanities and tables made of marble, limestone, travertine, onyx and other acid-sensitive stone. It is not applied to floors or walls.

Etching and staining. Etching is the dull, light-colored mark acids leave on marble and other acid-sensitive stone. In StainZero testing, the cured coating resisted lemon juice, vinegar, wine, ketchup, coffee and even battery acid. Like natural stone, the coating can still scratch or be damaged by heat, so cutting boards and trivets are recommended.

The Lifetime Limited Warranty covers stains and etch marks on residential countertops and tables, provided the coating was installed by a certified applicator and registered. It does not cover scratches, chips or heat damage; yellowing or discoloration of the coating; or damage from abrasive cleaners or harsh chemicals. Full terms and limitations are on the Warranty page.
