Does anyone know the color codes for Scotch Brite pads?

Coarse/medium/fine? And do those colors also apply to floor machine pads? Thanks

 

I'm thinking maroon is course, gray is fine.

is there a medium? I've never bought any if there is.

 

Whaddabout green? And RED.....

 

in the old machine shop I worked in (EXXON) I remember we also had green and white (white was super fine I think). We also had brown pads that were stiffer and fairly coarse....I remember one of the old Germans there used to call them "Bear-Tex" pads.....



.

 

Red=scuffing primer areas that are hard to reach
Gray=scuffing clear coated parts that are hard to reach (wheel lips on collision jobs)
white=ultra fine (I've never had a use for them yet)
Not sure how they convert to floor polishing, haven't done that yet either.

When I had my floor scrubber, I used black pads. They were the coarse ones, because I was scrubbing overspray from floor tile in my spray booth.

 

The white ones work good for cleaning overspray off of glass and chrome. Otherwise stick to the coarse red and fine gray.

 

I saw 3, but no mention as to which is more aggresive on the 2nd link. Got lost on the 1st link

 

The most agressive, of the "normally used" Scotchbrite pads, is the brown one........................Can't help on the florr scrubber part, as I gave up janitorial work LONG ago.....

 

In 3M:
Red is about 320- 400 grit
Grey is about 600-800 grit
White is about 1000

 

I know that is what 3M says, but I don't buy it. Put a new grey scotch brite in one hand and a new piece of 600 sandpaper and tell me they are even close. To me a grey pad feels more like a 280-320.

 

for floor machines lighter is softer darker is coarser. Mike

 

Hey guys I am a 3M Rep here in Detroit. Thanks for the interest in our produsts. Here's how it breaks down

7445 (gold) =clear blend scuff pad= prep for blends, good for metallics and pearls, easy buff back, clear prep adhesion

7446 (maroon)= primer prep scuff = prepping e-coat on new panels,door jambs, underhhod, provides good primer adhesion

7448 (grey)= use for prep of colorcoat areas and easy blends ( i.e. non metallic, pearl ) provides optimum color prep adhesion

I hope this helps- you can also check your paint companies P sheets to see what they reccomend. Also something to remember is with the new waterbased paints you should go up with your abrasive grades ( if you were sanding primer with 400 move up to 500 - 600 )

Thanks again for using 3M

 

I use the 2" and 3" scotchbrite discs and the colors to girt are as follows.
Brown- Coarse (80-100grit)
Red- Medium (180-220grit)
Grey- Fine (280-320 grit)
Blue- Very Fine. (400-600 grit)

 

Brown-left hand
Green-right hand

 

FWIW, Sheet from Mercer Abrasives [made in England] that came with scuff pads I picked up from a swap meet vendor says:

Light Green - Non abrasive for scouring and general maint

White - Non abrasive for polishing and light cleaning

Grey - Ultra fine silicone carbide abrasive for fine hand cleaning and finishing

Maroon - Very fine aluminum oxide for basic cleaning and finishing

Green - Fine aluminum oxide for removing rust or corrosion

Black - Medium aluminum oxide for heavy duty cleaning or fast action finishing

Tan - Coarse aluminum oxide for stainless steel aluminum and for stripping

Red is for everyday dishes, green for pots & pans.......on a more serious note the green ones will scratch glass if used agressively, for real

 

I found maroon is best for taking a scratch out of flat clearcoat, still not perfect... Gray will give it sheen, green will leave scratches, is what I found.

 

Just like sdandpaper, the product dulls with use. But I agree, it starts ourt coarser than they claim. Although it shortens the useful life of the product, sometimes I dull Scotch-Brite on a piece of steel plate before using it.

 

And the red is used where? Ouch!

 

I know green scratches glass. I use blue for general cleaning

 

i use to use the white pads and wd40 to polish acrylic duck calls..

 

"Acrylic ducks"?????

Similar to the pink plastic Flamingos, that go in your yard???
