Opal Anti-Etch - Frequently Asked Questions



What types of stone should Opal Anti-Etch be applied to?

Opal Anti-Etch is designed for stones made up of recrystallized carbonate calcite. Mostly metamorphic and sedimentary stones. (Marble, Limestone, Travertine, Sandstone, some
Dolomites and Quartzites)*


Can you apply this process to a backsplash?

Yes…however it is more expensive due to the application and curing process. If you choose to seal your backsplash, the best and most cost-effective way would be to have the backsplash sealed prior to being installed.


How hard is Opal Anti-Etch finish?

Opal Anti-Etch forms a protective layer over your natural stone that will not etch or stain. It is harder than most all metamorphic stones for which it is designed as a sealer.


Will Anti-Etch surface scratch?

Opal Anti-Etch will be harder than most of the stones it is protecting, so it will be harder to scratch. The great thing about Opal Anti-Etch is that if scratches develop it is a simple repair of the scratches themselves rather than having to refinish a large area, like you would natural stone.


What is the cost of applying process?

Type of finish, type of stone or concrete, location, access, amount of prep work involved, etc. all factor into cost. A good range to expect would be from $85 to $120 per square foot depending on the factors above.


What is the appearance of Opal Anti-Etch after a finished application?

Opal Anti-Etch is applied as an ultra-thin layer such that the natural color of your stone is is not interrupted or disguised in any way. As a matter of fact, one would be tempted to just reach out and touch the finished stone just to prove to themselves that is actually sealed because it looks so natural when applied, cured, and finished properly.


How long does the application, curing, and finishing process take?

Typical kitchen will take 2 days….one for the application, curing, and finishing process; and one for touch-up if needed, clean-up, and quality inspection.
*With Limestone and Travertine a primer might be necessary so as not to change or enhance the
natural color of the stone.

*Some Quartzites and Dolomites might need Opal Anti-Etch to protect them. A simple test can
be performed to determine if it is needed.
