Customer Reviews for 3M Pro Grade Precision 9 in. x 11 in. Extra Fine 320-Grit Sheet Sandpaper (4-Sheets/Pack)

I’m actually excited about writing this review - for the last 3 years have used your basic wood sand paper to clean my lawnmower deck, but this time I didn’t start soon enough. It got some angry rust and I needed something stronger that would last longer and take it down to the metal easy & fast. This product has done everything that I’ve dreamed of and has eliminated a lot of the extra time - I should have this project done very soon and repaint it. I highly recommend this item and if you have an orbital sander it’s eliminated a lot of the extra time if done by hand.

Was part of the process (scraping, mudding, sanding) in restoring hallway before applying Zinsser triple thick base coat.

3M Pro Grade is very high quality, flexible, fast cutting and durable sandpaper. Low quality sandpaper uses more paper, takes more time. Spend smart. Full size sheets same a ton of money if you use the 3M rubber sanding block...Fold the sheet in half, and again and you can cut 4 pieces that are 2 3/4" x 9" and are the perfect size. 4 per sheet, 4 sheets is 16 perfect sanding block sized for $6.99 .The slightly bigger 3M precut sheets are 6 for $6.99.

Excellent for application requirements

I like to work with HDPE (high density polyethylene)- basically melted detergent bottles as a hobby. This is the best I’ve found for durability, effectiveness, and ease of keeping clean and viable. Even finely ground plastic doesn’t gum up this stuff. Fantastic.

Did exactly as promised

Got these to sand up some wood filler on my hardwood floors. They cut very easy in to 4 1/2" x 5 1/2" pieces for a palm sander. I was a little surprised because I had been using diablo sandpaper before. These did a really great job. They did gum up a bit, but i think that was due to trying to smooth down excessive wood filler. Overall very happy with them.

We are building a doll house from a kit and the directions told us to paint everything to raise the wood fibers and then sand the pieces so the wood peeks through. So we went with a fine sand paper to prevent accidentally distorting the pieces when sanding. This sandpaper is strong and lasts a long time. We finished the job and the sandpaper is still usable.

Product worked great and help get cabinets sanded nice and smooth! Would definitely recommend this brand and will be buying again.

This Pro Grade Precision 320 Grit Medium Advanced Sanding Sheets delivers a surprisingly good result for the price paid. I used it to sand the drywall surface to make it smooth before i paint it. Only 3 sheets which were enough to complete my task. Inexpensive solution for any DIYers

First 3M is my go to sandpaper, no matter what the grit. It is durable and easy to handle and gives you the results you are looking for. 220 is one of my top used grits, I believe to be the pretty grit to go to before staining your wood, and smooth enough to be your final sanding on a lot of projects. I seldom go much higher on any project I am applying a finish to.

This is not good sandpaper. I was just sanding using a brand new Milwaukee palm sander and this paper breaks apart and worst of all, the great "no slip" backing they used glued itself to my sander pad. I have contacted 3M and they have opened a file on it. Beware!

This sandpare is junk. I bought 2 packets from our Home Depot because 3M is supposed to be one of the best. It's not, maybe their other types are but this stuff comes apart fast and easy. I even bought a new palm sander because I thought maybe something was wrong with mine. NOT SO ! I thought it was too loose, then too tight No difference. Save yourself the hassle and don't buy this stuff, buy the proven Norton paper. Hands Down better !!!

Great sandpaper. Lasts a long time.

Fantastic~ Used imedium grit on my little sander and I could get four section out of a Sheet. . Used to Sanded down wrought iron railing. Worked perfectly and lasted longer that other products.

Good sandpaper, and it seems to last a long time. Quite durable.

This "Sticky Back" sand paper stuck to the pad on my finishing sander (that I've had for 20+ years) and pulled the pad right off. Now I need new sand paper and a new finishing sander. No, I would not recommend this item.

This product made refinishing my stair rails so much easier. It contours around all the curves and gets into all the little cracks. I wish I had known about this sandpaper earlier so I could have used it on some of my previous projects. It's a little more expensive than regular sandpaper but totally worth it.

Easily removed and very little paint seeped underneath

The purple stuff works fantastic on wood, drywall etc.. Seems to last forever. WHAT A GREAT PRODUCT!!!

Store not very reliable. Left item that was prepaid at pickup, after waiting for 20 minutes to bring out to car only after calling the customer service desk .

good value, convenient location
