Thank you for your quick responses, Bridget and Richard!
Further internal discussion with the laboratory and within Yale EHS, opinions have moved toward the stainless-steel solution. Specifically, the new quote request is for 316 Stainless @ 16 gauge which will screwed down to the surface.
Thanks for the specifics on use type and the results - I will further highlight my previous guidance about corrosives.
Gratefully,

Hi Paul,
We have used the 16 gauge stainless steel for covering work surfaces for chemical fume hoods and countertop surfaces.
These areas have been designated for non-corrosive chemicals work only.
We have had no problems after installation and use for the last 6 years.

Good afternoon DCHAS,
I'm wondering if any of you have any experience painting / resealing natural stone work surfaces in chemical fume hoods. A laboratory has three aging hoods that cannot be readily replaced. Considerations have included an epoxy-based sealant / paint OR installation of a ~16 gauge stainless steel sheet. Of course these cannot affect designed airflow, sash movement, etc.
We are awaiting confirmation that their scope of work will not increase beyond fine powders (metals, salts, silica), oils (mineral mostly), and cleaning solutions (soap, ethanol/IPA). I have also asked for the specific product(s), manufacturers literature on intended use and chemical resistance, as well as their contractors experience using such materials on natural stone work surfaces.
Any thoughts, ideas, or experience from the group?
Thank you in advance for your time and consideration.
Best,
-P
