The specifications provided for resinous flooring include 09 67 23.14 Chemical Resistant
Resinous Flooring and 09 67 23.15 Fuel Resistive Resinous Flooring, 3-coat System.
On Drawing A-601 the description for F1 finish is "Exposed Concrete w/ Slip Resistant

Resinous Flooring and 09 67 23.15 Fuel Resistive Resinous Flooring, 3-coat System.
