Mirror Finish in 2 Steps Starting with a 2B Finish

Step 1

Pre-Grinding:

If thick welds must be blended, we recommend using a Plantex SUNFIRE Ceramic flap disc 93520 (4½ x 40/60grit) using the Varilex tool (65000A) in the same direction as the weld.

Pre‐grind with PTX Ceramic grinding belt 42480 (80 grit) on the PTX Eco Smart linear tool to level welds and blend in any swirl scratches. Use elliptical motion when blending to produce an even finish.


Pre-Finishing:

Finish with PTX “TZ” pyramid belt sleeve 42265 (320 grit) or 42245 (400 grit) then the 42230 (600 grit) to remove the scratches and prepare for pre-polishing. Change direction 90 degrees with each grit change to cut the scratches into smaller size.

Pre‐polish with PTX “TZ” pyramid belt sleeve 42216 (1200 grit) then 42206 (2000 grit) for final polishing. Change direction with each grit change.


Pro Tips:

With each change of grit, change the presentation by 90 degrees, to reduce the scratch into smaller pieces that can be removed by the next grit size. Tool working speed between 1000-3000 rpm

Apply a consistent downward pressure, slightly more than the weight of the grinder when finishing with the PTX “TZ” pyramid belts, Increase tool speed slightly with each grit change.


Step 2

Final Polishing

Mirror Finish On 2B Stainless Steel

Final finish with PTX felt belt sleeve 42013 or PTZ Super Polish belt sleeve 42013N starting at 1000 rpm and gradually increase up to 3000 rpm to prevent the compound from flying off.

Pre polish with White PTX polishing compound 40013. After polishing sprinkle PTX Brightex Softclean powder in a scatter can 40029 and wipe with a microfiber cloth 40031 to remove any paste residue.

Polish with blue PTX polishing compound 40014. After polishing sprinkle PTX Brightex Softclean powder in a scatter can 40029 and wipe with a microfiber cloth 40031 to remove any paste residue.

Mirror polish using the cotton buffing wheel CS 2410 and pink PTX polishing cream 40015T.


Pro Tips:

Always use a separate PTX felt sleeve for each polishing compound and cream so that the different compounds do not get mixed together. Mark each sleeve W and B and store it in a zip lock bag for protection.

Pastes and creams must always be applied to PTX sleeve never to the work surface.

After each polishing step remove the remaining residue with PTX Brightex Softclean powder 40028, simply scatter it on the work piece and wipe it off with a microfiber cloth 40031 to remove any paste residue.

The final finishing should be at the highest speed 3800 rpm in one direction and no downward pressure. Let the cotton buff just barely touch the surface.
