What an etch actually costs you.
A sealer is not a coating.
Most commercial stone has been sealed at some point, and the assumption is that sealed means protected. Two things are worth separating.
A penetrating sealer lives beneath the surface.
It soaks in, it is invisible, and it slows staining. It also wears, faster when harsh over the counter chemicals are part of the nightly routine.
A coating lives on top of the surface.
It is a true top coat, often called a topical sealer. MORE™ AntiEtch™ belongs in this category, and it is built for the specific job of standing between acid and stone.
What makes the difference in a commercial building is not only the product. It is whether the surface was prepared and the product installed the way the manufacturer specifies, every time, on every surface. That is The Pure Light Standard™: the same preparation, the same application, the same walkthrough, documented at the end.
How the coating actually goes on.
Step 1
Assess.
We walk the property and identify the stone on site. If nobody is sure what the surface is, we use professional Stone ID kits during the free estimate.
Step 2
Restore first, if the surface needs it.
Coating does not hide damage. Where etches or dullness are already present, restoration is scoped and completed first, so the coating goes onto a finished surface.
Step 3
Prepare to specification.
The surface is cleaned and prepared the way the manufacturer requires. This is the step generalists skip, and it is the step that decides whether a coating lasts.
Step 4
Apply as a Certified Applicator.
MORE™ AntiEtch™ is a manufacturer system, not a Pure Light™ invention. Certification is what allows it to be installed correctly, and Pure Light™ is one of only two certified applicators in San Diego County.
Step 5
Walk it and document it.
A post job walkthrough with your team, then a written job summary of what was coated.
Warranty
Jobs completed October 2025 and later carry a factory lifetime warranty against stains and etches. Work completed before October 2025 carries the earlier ten year warranty.
Any finish can be achieved, whether factory or not.
MORE™ AntiEtch™ is available in polished, satin, and honed.
MORE™ AntiEtch™ Finish
It can match the finish already on the stone, or change it: a polished counter can go to a flat matte, and a matte counter can go to a polished finish.
That range is one of the reasons people choose it. The other is the lifetime warranty. The coating is designed to stop marble from etching and staining, permanently.
MORE™ AntiEtch™ is for marble, travertine, limestone, and onyx countertops. It is not a sealer. It is not for floors, and it is not for granite.

Protect it once, instead of restoring it twice.
One walkthrough, the stone identified on site, a written scope, and a coated surface that stops absorbing the cost of everyday use.
