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.
Claims22
