Question 1

What does the StainLock™ Lifetime Limited Warranty cover?

Accepted Answer

The StainLock™ Limited Lifetime Warranty covers professionally applied StainLock protection on marble, granite, quartzite, limestone, travertine, and other natural stone surfaces. It covers acid etching and staining of the treated surface for the life of the countertop, provided the product was installed by a certified StainLock applicator.

Question 2

How long does the StainLock™ warranty last?

Accepted Answer

StainLock™ is backed by a Limited Lifetime Warranty. Because StainLock bonds within the stone at the molecular level rather than sitting on the surface, it does not wear off or need reapplication, so the protection — and the warranty — lasts for the life of the countertop.

Question 3

Do I need to register my StainLock™ warranty?

Accepted Answer

Yes. Your Limited Lifetime Warranty must be registered and documented on the day of installation. Certified StainLock applicators complete the registration as part of the installation process, which is one of the reasons StainLock is installed only by certified professionals.

Question 4

What voids the StainLock™ Lifetime Limited Warranty?

Accepted Answer

The warranty is valid only when StainLock is applied by a certified StainLock applicator and the warranty is properly registered. Damage from physical abuse such as chipping, cracking, scratching, or impact, from structural movement or improper installation of the stone itself, and from products applied to the surface after installation are not covered.

Question 5

Which stone surfaces are covered by the StainLock™ warranty?

Accepted Answer

The StainLock™ Limited Lifetime Warranty covers treated marble, granite, quartzite, limestone, travertine, and other natural stone surfaces, including kitchen countertops, islands, bathroom vanities, and bar tops.

Question 6

Is the StainLock™ warranty transferable if I sell my home?

Accepted Answer

Warranty transfer terms depend on the registered installation and the specific warranty documentation provided by your certified applicator. Contact StainLock support with your warranty registration details to confirm the options available for your installation.

Question 7

Who installs StainLock™ so the warranty stays valid?

Accepted Answer

Only factory-trained, certified StainLock applicators can install the product. StainLock is not sold for DIY use, and installation by an uncertified party does not carry the Limited Lifetime Warranty.

Question 8

How do I make a claim on my StainLock™ warranty?

Accepted Answer

To make a claim, contact StainLock with your warranty registration details and documentation of the affected surface. Because StainLock is a permanent, molecularly bonded sealer, claims typically involve an inspection by a certified applicator to confirm the installation and assess the surface.
