  • Compositions and methods for coloration and/or staining of galvanized metal surfaces
    Patent number: 8936676
    Abstract: An aqueous liquid solution containing soluble salts of coloring metals—particularly manganese and ferric iron along with a sugar source and fulvic and/or humic acid can be readily applied to galvanized metal surfaces impart a natural color tone to such surfaces. In this manner the visibility manmade structures like fences and guardrails is quickly and easily reduced and readily blended into the natural background. The liquid solution can be readily sprayed on galvanized surfaces. When the ambient temperature is warm natural color will develop two-three weeks.
    Type: Grant
    Filed: September 30, 2011
    Date of Patent: January 20, 2015
    Assignee: Foster-Gardner, Inc.
    Inventors: Edward F. Foster, Thomas T. Yamashita, Brian M. Hardin

  • Compositions and methods for deep-seated coloration and/or staining of the surface terrain, construction material, boulders and rocks
    Patent number: 8075684
    Abstract: An aqueous liquid solution containing soluble salts of coloring metals—particularly manganese and ferric nitrate along with a sugar source and fulvic and/or humic acid can be readily applied to rock, soil or artificial construction surfaces impart a natural color tone to such surfaces. In this manner the visibility manmade disturbances is quickly and easily reduced and disturbed areas readily blend into the natural background. The liquid solution can be readily sprayed on rock or other surfaces. When the ambient temperature is warm natural color will develop in 4-8 days.
