| SSPC-2 Hand Tool Cleaning Preparation |
|
Hand tool cleaning is a method of preparing steel by the use of non-powered hand tools. Using hand tools, remove all loose mill scale, rust, paint, and other detrimental foreign matter. It is not intended that adherent mill scale, rust, weld slag or paint be removed by this process. The matter is considered adherent if it cannot be removed by lifting with a dull putty knife. Edges of old paint should be feathered to give the repainted surface a reasonably smooth surface. |

| SSPC-3 Power Cleaning Preparation |
|
Power tool cleaning is a method of preparing steel by the use of powered hand tools. Using power tools, remove all loose mill scale, rust, paint, and other detrimental foreign matter. Rotary or impact power tools can be used to remove stratified rust or weld slag, taking care not to burnish the surface. The matter is considered adherent if it cannot be removed by lifting with a dull putty knife. Edges of old paint should be feathered to give the repainted surface a reasonably smooth surface. |
