1. SP-1 Solvent Cleaning: Remove all grease,oil, salt, acid, alkali, dirt, dust, wax, fat, foreign
matter and contaminates, etc. by one of the following methods: steam cleaning, alkaline
cleaning, or volatile solvent cleaning.
2. SP-2 Hand Tool Cleaning: Removal of loose rust, loose mill scale and loose paint to a clean
sound substrate by hand chipping, scraping, sanding and wire brushing.
3. SP-3 Power Tool Cleaning: Removal of loose mill scale and loose paint to a clean sound
substrate by power tool chipping, descaling, sanding, wire brushing and grinding.
4. SP-5 White Metal Blast Cleaning: Complete removal of all mill scale, rust, rust scale,
previous coating, etc., leaving the surface a uniform gray-white color.
5. SP-6 Commercial Blast Cleaning: Complete removal of all dirt, rust scale, mill scale, foreign
matter and previous coating, etc., leaving only shadows and/or streaks caused by rust stain
and mill scale oxides. At least 66% of each square inch of surface area is to be free of all
visible residues, except slight discoloration.
6. SP-7 Brush-Off Blast Cleaning: Removal of rust scale, loose mill scale, loose rust and loose
coatings, leaving tightly-bonded mill scale, rust and previous coatings. On concrete surfaces,
brush-off blast clean to remove all laitance, form oils and solid contaminates. Blasting
should be performed sufficiently close to the surface so as to open up surface voids, bugholes,
air pockets and other subsurface irregularities, but so as not to expose underlying aggregate.
