ABSTRACT:
A preferred method by which microorganisms and nutritive media are sprayed, brushed, dripped, or otherwise applied, onto freshly cut rock, stone, freshly formed concrete, or other hard manmade surface, in order for the target surface to take on a weathered appearance in the least amount of time. The present inventive product and process by product creates a process by which surface materials may be scraped or gathered from a nearby location, mixed with water and/or a nutritive media, and either further treated to promote additional growth of necessary microorganisms, or the directly applied to the surface of the freshly cut rock or stone, or freshly formed concrete or other hard, manmade surface thereby providing a weathered appearance in the shortest period of time. Newly built structures of rock, stone, concrete, or other hard surface are thus provided with an appearance which fits into mature and established areas.
