A concrete colorant that is an interior, translucent, subsurface, pH-neutral dye. 

For use on any indoor substrate with suitably prepared concrete, especially in high humidity environments where other colorants do not perform.  Can be used for industrial, manufacturing, light assembly, warehouses and distribution centers, food service operations, retail stores and showrooms, parking decks, garages, airports, and hospitals.

“Utilizes nano-sized particulates to penetrate the concrete, depositing colorant embedded in the concrete subsurface and promoting a longer lifecycle.” -Retrieved 1/31/2025 from https://greenumbrellasystems.com/nanodye-concrete-colorant/
