It should be specified only when a compatible coating <br />will be applied. The primary functions of blast cleaning before <br />coating are (a) to remove material from the surface that can <br />cause early failure of the coating and (b) to obtain a suitable <br />surface profile (roughness) to enhance the adhesion of the <br />ASTM International (ASTM), 100 Barr Harbor Drive, West Coshohocken, PA 19428-2959. <br />4 <br />
