Removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter by hand chipping, scraping, sanding, and wire brushing.
Prior to the use of hand tools, remove visible oil and/or grease by power or hand washing. A surface prepared with hand tools requires that all loose mill scale, loose rust, loose paint and other loose foreign material be removed. It is not intended to remove adherent mill scale, rust and paint. Material is considered to be adherent if they can not be removed by lifting with a dull putty knife. Types of tools used include: non-woven abrasive hand pads, wire brushes, and scrapers. 3M Scotch-Brite Hand Pads can be used to accomplish this type of preparation.
