#3 Finish
Also called Grinding, Roughing or Rough Grinding

These finishes are coarse in nature and usually are a preliminary finish applied before manufacturing. An example would be grinding gates off of castings, deburring or removing excess weld material. It is coarse in appearance and applied by using 36-100 grit abrasive.

When the finish is specified as #3, the material is polished to a uniform 60 - 80 grit.

#4 Architectural Finish
Also called Brushed, Directional or Satin Finish

A #4 Architectural Finish is characterized by fine polishing grit lines that are uniform and directional in appearance. It is produced by polishing the metal to a 120 - 180 grit belt or wheel finish and then softened with an 80 - 120 grit greaseless compound or a medium non woven abrasive belt or pad.

#4 Dairy or Sanitary Finish

This finish is commonly used for the medical and food industry – almost exclusively used on stainless steel. This finish is much finer than a #4 Architectural Finish. Great care should be taken in removing the surface defects in the metal – like pits – that could allow bacteria to grow. A #4 Dairy or Sanitary Finish is produced by polishing to a 180 - 240 grit belt or wheel finish and softened with 120 - 240 grit greaseless compound or a fine non woven abrasive belt or pad.

#6 Finish or Fine Satin Finish

This finish is produced by polishing to a 220 - 280 grit belt or wheel finish and softened with a 220 - 320 greaseless compound or very fine non woven abrasive belt or pad. Polishing lines should be soft and less reflective than a #4 Architectural Finish.

#7 Finish

A #7 finish is produced by polishing to a 280 - 320 belt or wheel finish and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they should be very dull. Carbon steel and iron are commonly polished to a #7 finish before chrome plating. A #7 finish can be made bright by color buffing with coloring compound and a cotton buff. This is a good way to keep polishing costs down when a part needs to be shiny but not flawless.

#8 Finish or Mirror Finish

This finish is produced by polishing to at least a 320 grit belt or wheel finish. Care should be taken in making sure all surface defects are removed. The part is sisal buffed and then color buffed to achieve a mirror finish. The quality of this finish is dependent on the quality of the metal being polished. Some alloys of steel and aluminum cannot be brought to a mirror finish. Castings that have slag or pits will also be difficult – if not impossible – to polish to a #8.

A medium greasy, fast cutting compound suitable for buffing and coloring out the work in one operation. Our most popular grade for a large variety of work.


A very dry grade intended for use on work that has a good starting surface such as light stampings and mouldings. Can be used as a coloring compound to bring out a mirror bright luster after polishing lines have been removed using a more aggressive compound. Light green in color.


Wagner’s most aggressive steel compound. Sharp abrasives produce an extra fast cutting action. Ideal for buffing out light tool marks or scratches. Its use may reduce or eliminate the need for finer belt operations.

May be used to remove tarnish from brass, bronze, aluminum and stainless steel. Leaves a silicone film for longer protection

  1. Grind out any welds and any deep gouges in the material. Always be careful not to over grind or under cut the welds. Feather any gouges carefully.
  2. Attach the Wagner Finishing Pulley – PP1 – to a disk grinder as shown below.
  3. Spot rope any ground welds and repaired gouges and deep scratches with a 50 grit belt. Be sure to put a twist in the belt as shown in the photo to keep the grit portion of the belt from damaging the finishing pulley. Only do this step if your
    material has bad spots that require this aggressive process. You will only want to be as aggressive in finishing as you need to be. If in doubt, go to step 4.
  4. Rope with an 80 grit belt
  5. Rope with a 120 grit belt.
  6. For final clean-up and finish, rope with a medium non woven abrasive belt.

Always handle material with care. Even stainless steel surfaces will nick and scratch when handled improperly.

In the case of stainless steel, avoid as much contact between it and ferrous material as possible. Always use new belts. Do not use any tools or belts that were used on any other materials – especially steel. Otherwise you run the risk of
contaminating the stainless steel with imbedded ferrous particles that will cause it to rust.

When polishing is completed, immediately wrap the finished material to avoid contamination from ferrous particles prior to installation.
Stainless Steel Preventive Maintenance Suggestions
  • Inspect the installation on a frequent schedule taking note of discoloration and stains. Discoloration can and should be removed by cleaners recommended for stainless steel.
  • Ongoing maintenance consisting of a fresh water wash and wiping with a clean cloth is recommended to minimize deterioration. In all but the most severe cases, this regular washing will eliminate the need for refinishing.
  • Never use steel wool or harsh abrasive elements.
