Title: Grit levels
Post by: Bruce on June 17, 2003, 01:56:41 AM

I'm about to get my spinner and was wondering if someone would please post the grit levels for scotch brite pads.  Also do you use them by hand or do you use one of those contoured blocks?

TIA,
Bruce

I can't advise you on the blocks. On the Scotch Brite Pads, Wild Octopus has them.  Burgundy   400 Grit   Green  600 Grit  Grey  800 Grit  White  1200 Grit
That is how they list them.

Just to be a little too picky, but more precise, the grit level of the maroon is supposed to be 320.

Hey everyone, I can't say what color is exactly what grit as I don't know. I was only writing (quoting) what Wild Octopus says they are, in their ad on this site.

Bricky,

Don't feel bad. What you did was excellent. Here's what I saved in my files when this subject was discussed in the recent past:

3M Scotch Brite:

7445 - White pad, called Light Duty Cleansing  - 1200-1500 grit
7448 - Light Grey, called Ultra Fine Hand      - 1000 grit.
7447 - Maroon pad, called General Purpose Hand - 320 grit
6444 - Brown pad,  called Extra Duty Hand      - 240 grit
7446 - Dark Grey pad, called Blending Pad      -  150 grit
Green Scotch Brite is available EVERYWHERE. It's 600 grit.

The Blue pad is a recent discovery. I've found it on pot scrubbers, saying it will not scratch teflon and non-stick finishes. So 800 is a good guess for its grit level.

The blue one is also sold at boating supply stores. I don't know the number right off hand but its good for cleaning fiberglass without scratching it.

When you resurface, pay attention to the particle type and ball type when choosing a method for resurface.  For example, you need sandpaper or Trizact pads with glass and ceramic particle balls, which silica particle balls should be resurfaced using scotchbrite -- not sandpaper.  For the most part, reactive balls work well with either, though I prefer sandpaper for finishing before a polish.
