Abstract (en)

[origin: WO02094737A1] The present invention consists of preferred methods or embodiments by which microorganisms and a nutritive media are sprayed, brushed, dripped or otherwise applied onto freshly cut rock or stone, or freshly formed concrete or other hard, man made surface, in order for the subject surface to take on a weathered appearance in the least amount of time. It is believed that stone quarries, freshly hewn rocks and newly built buildings may take on an appearance which may be considered out of place next to more mature, established areas. The present inventive process and product by process rectifies these issues by creating a process by which surface materials may be scraped or gathered from a nearby location, the materials may then be mixed with water and/or a nutritive media, and the materials may then either be further treated to promote additional growth of necessary microorganisms, or the organic mixture may be directly applied to the surface of the freshly cut rock or stone, or freshly formed concrete or other hard, man made surface, in order for the subject surface to take on a weathered appearance in the shortest period of time.
