I'm surprised because I've done prior research into the Granite Deck system, made, as I understand, by Carboline and privately labeled and marketed by Nevada Coating Systems.

I've not found any listings before nor did I find any today at ICC_ES' website under Div 7 Pedestrian Traffic Coatings at this link. http://www.icc-es.org/reports/index.cfm?csi_num=07%2018%2013&view_details

ICC-ES issues reports for building products that have under gone testing in a strict lab controlled environment that is independent of the manufacturer. The report allows building code officials to determine of the product meets the building code requirements for the type of building be constructed.

As we cannot find any reports or other proof at ICC-ES or Nevada Coating Systems website to support that Class A claim, we are issuing a warning to consumers to be cautious about unsubstantiated claims for fire resistance.

In our own limited testing of a Decktech Granite Deck sample, we found the sample began to burn with several wood coals burning much like an ember would from a fire. We can not make any determination as to whether it meets ICC-ES criteria, so we would advise that you ask questions and obtain written proof of any oral or website claims. https://www.dropbox.com/s/ule2h0yitcr32xh/2012-05-28%2010.14.16.jpg

ICC-ES' criteria for fire resistance is-

4.3 Fire-classified Roof-covering Test: For applications as a classified roof covering, reports of fire-classified roof-covering tests in accordance with ASTM E 108, UL 790 (IBC and IRC) or UBC Standard 15-2 (UBC) shall be required. A minimum Class C classification shall be required.
