This Surface Preparation Commentary (SP COM) is intended to be an aid for the coating specifier in selecting methods, materials, and standards for specifying the proper surface preparation for steel, and other metals (not including ductile iron pipe). The use of these standards in a coating specification will give direction to the contractor regarding what is required and give direction to the inspector on verifying compliance to the specification.
