3M Tr-M-Ite Polishing Papers - could this be the best abrasive there is for mirror polishing silver, acrylics, resin, wood and many other materials?

This is a great value BULK BUY set with 12 sheets of the 3M WetorDry Tri-M-Ite Polishing Papers. You get two full-sized sheets (US letter size which is very similar to A4) of each grit.

They're made from micron sized abrasive particles, slurry coated onto a non-woven synthetic backing. They are soft, cloth-like and paper thin, so wraps smoothly around your piece. You can also wrap the paper around a wooden stick, if you only want to polish the raised surfaces on your piece, for instance, if you have oxidised the piece.

The precision micron grading provides a uniform, consistent finish. These are sometimes referred to as Tri-M-Item papers, or lapping papers. They really give you the most fantastic mirror-like finish on metal clay and silver.

Works wonders on silver clay, sterling silver, and also resin like Alumilite Resin, plastics, acrylics, polyurethanes surface composites, and. Use to remove scratches and bring back transparency to acrylic and polycarbonate. The precision micron grading provides a uniform, consistent finish.

Luthiers and instrument makers - this product is loved by many of you for giving a beautiful finish to your frets and other wood work.

To hand finish your work to a mirror finish, start with the coarsest grit and work to the finest grit. When you see uniform fine lines, move to the next grit. Do not skip grits or you won't get a mirror finish. Grits are colour coded for easy identification.

Each sheet is 21.6cm x 27.9cm (8.5" x 11"). This is a US Letter size, which is very similar to an A4 sheet (A4 is a little taller, and Letter is a little wider of the two).

Please note - these set have not been split up, or the sheets been cut in half. You get 12 FULL SIZED sheets, TWO sheets of each grit.

The set includes 12 sheets:

  • 2 x Light Green - 1 Micron / 8,000 grit
  • 2 x Mint - 2 Micron / 6,000 grit
  • 2 x Pink - 3 Micron / 4,000 grit
  • 2 x Blue - 9 Micron / 1,200 grit
  • 2 x Grey - 15 Micron / 600 grit
  • 2 x Green - 30 Micron / 400 grit

TOP TIP - Write the grit with a marker pen on the back to help you identify the grit even when it gets a little dirty.


You can also buy each of these as individual sheets (click here to see the range) perfect for when you find your favourite grit that you use more than others.

Best way to hand polish. Great product.

3m polishing papers

Written by Susan on 17th Apr 2021

These are great! When I got them I was a bit dubious as they look just like, well, paper! But on using them, I am thrilled. Just polished up two silver bangles I made and they are so shiny and smooth. Would definitely buy these again!

Great for polishing resin

Loved this! My crafts turned out shinier that i could imagine :D

Awesome Polishing Papers

Written by Leigh Minx Armstrong on 16th Nov 2020

Hands down the best way to start with polishing when you are a newbie! All of my Students get a sample of these papers to use in class, a really inexpensive way of getting a professional finish to your work & they can be used over & over again.

amazing for polishing epoxy resin pieces

Written by Maria eugenia on 8th Sep 2020

I used these papers with a 500 grit sandpaper in order to sand and polish some epoxy resin pieces I made, and they work perfectly. Definitely will buy again once I finish the ones I bought.

Great Polishing papers

Written by Marie on 8th Jun 2020

These seem a little pricey up front, but you get so many papers, and they're huge- they'll last ages as long as you keep them stored neatly and use them carefully. It's always amazing to see my fired silver clay pieces shine up step by step with these- they really give a fantastic finish.

Great polishing papers

Written by Jade on 30th Apr 2020

These papers are great value for money! They came well packaged and flat, with a handy sticker on the front to remind me what colour = what micron. So far I’ve used them to sand 2 12pc dice sets, and they are holding up well! I’ll need more of the first micron in a few more sets, but every other page shows barely any wear and tear. And the mirror shine is beautiful on the finished pieces

These papers are excellent quality and last for ages. Working through the papers allows a beautiful shine to be created on silver clay pieces. A must have item.

3M polishing papers

Excellent for gradual polishing, great to be able to cut them down and fold them easily to reach the more difficult to reach places

Excellent and reasonably priced, i have used them a couple of times since they arrived and the finish is stunning.

Must have

Written by Amy on 13th Jan 2018

If you are looking to file your silver clay before you fire these are a must have. If you are looking to bring your fired pieces to a mirror shine these are a must have! Be sure to use different pieces on clay / fired pieces.

What else would I use?!

Written by Jo Richards on 17th Feb 2017

These are perfect for finishing. I cut mine into 4 squares and number them in order of courseness (I have a terrible memory!). This is the only method of polishing I use - kiln to mirror finish with nothing else - and they're great value!

Easy to Use

Written by undefined on 11th Sep 2016

These sheets are easy to use . Cut them into smaller squares and can get them into all sorts of spaces . Really like them.

I don't know how I managed without these.

Written by Lorna Briers-Parr on 21st Aug 2016

I know you recommend not using these papers on dry clay but, despite the fact they clog up quickly, they leave such a beautiful finish that it is worth it.

A must have in your kit

Written by Maria Mcleod on 19th Aug 2016

I was introduced to this product during a metal clay work shop hosted by Nicola Beer. I realised that using something as simple as the right grade and quality of polishing papers makes all the difference to the finished quality of your piece. I have used these after purchase and have not been disappointed. They are durable and flexible to use and cost effective.

great finishers.

Written by Ms Rachel Broadbent on 15th Aug 2016

These are great for hand finishing silver and for polishing pre tumbling. There is a good variety of grits and they produce a good finish when working through them if you need to hand finish your silver.


Written by Lacey Kerr on 15th Jun 2016

Wouldn't be without them now, can't believe I waited so long to buy them in the first place! Great product!

A mirror finish

Written by Grainne Reynolds on 26th Feb 2016

This set of polishing papers are perfect for achieving a mirror finish on fired silver clay, work your way through the papers from rough to smooth for a flawless finish.

Fantastic for pre-firing polishing papers

Written by Michele Trapiche on 13th Nov 2015

These papers can be used wet or dry and on pre-fired or post fired jewellery. Using these (in order) on pre-fired silver art clay, really highlights any areas that require additional sanding or polishing that you may not notice before firing. If these are used pre-firing, polishing post firing is much easier and definitely gives a mirror finish.

Does the job well

Gives a good high polish finish to silver clay items.

These are the perfect alternative to machine polishing. No messy rouge everywhere, just clean, quiet, take anywhere sheets.

Smooth Rooks & Crannies

Written by Jan on 30th Oct 2012

Soft & pliable - a must for your tool box. Tip 1: Cut into small pieces or invest in some thin double sided tape, & glue strips around toothpicks, wooden skewers & thin wooden dowel rods, for a range of useful polishing tools, pure magic. Tip 2: Listen to the sound when you start sanding and you will hear it smooth out when it is time to move on to the next grade of paper.

hard work!

Written by undefined on 5th Jul 2012

I found it hard work and difficult to know when you had done enough with each sheet. Also it seemed to get a layer of sticky dirt on the resin after i had been polishing it for a while. I wasnt sure if i was doing it right as i came with no instructions on how to know when you had done enough on each layer. I found that washing the piece after each layer seemed to help remove the dirt and get it ready for the next sheet.


Written by Kath on 10th May 2011

just used these for the first time, Sue is right...plenty of elbow grease needed but the result is fantastic and well worth it!!!!

These + elbow grease = a lovely shine

Written by Sue W on 13th Oct 2010

You have to use elbow grease to get a mirror finish with these but I find that if you put a lot of work in with the coarser grits, you get a better finish and don't need to do so much with the finer ones. This means that I tend to get through the coarser sheets faster than the finer ones. They give a lovely shine which is enhanced with a final polish with Wenol.
