Grinding tools and impact tools are both acceptable means for achieving the level of cleaning specified. On welded work removal of all welding flux, slag, and fume deposit are necessary as those are the contents ssoc promote paint failure on welding joints. Ssppc the use of impact or abrasion from these power tools, non-adhesive particles are removed in a faster and less expensive manner than some other cleaning methods. So it is in the best interest of the owner to provide the contractor with sample surfaces of what is expected.
