Questions & Answers


Which grit is recommended to remove paint from and iron/metal fence.

Asked by MJM January 16, 2021

I would imagine the 60Grit would work well, just let the paper do the work- don't lean into it. Should take off chipped and loose paint quickly.

How do the hook&look backing attach to my Dewalt 6420 disc sander?

Asked by Ken June 20, 2020

You will have to buy a psa to hook and loop conversion pad. It will attach to your psa sander and the other side is hook and loop so you can attach these sanding discs to it. I use only hook and loop sanding discs, and I find them to be economical and quicker to change from one grit to another. Hope this helps.

need 9in round sandpaper with hole in center

Asked by tom June 18, 2020

I know DIABLO makes multiple sizes of round, center whole sanding discs, some even larger than 9", but not sure about about 9" rounds per se. I think Eagle and Norton make 9" center whole discs but not sure where to purchase those brands except perhaps on line.

How do they work with a Dewalt palm sander

Asked by Frank June 17, 2020

Hi Frank, These discs will work with any 5" ROS sander.

Is the "hook" portion of the backing included?

Asked by Steve May 22, 2020

No. Im using them on a dewalt orbital sander that has the hook on it. They are just the basic pads.

prodruct behind have adhesive tape or fabric to use against the velcro disc?

Asked by Mari May 7, 2020

Fabric. It works like velcro. It doesn't work very long if you are applying pressure to the sander, but these do the job.

Strip off old paint, using a orbital sander, what grits are recommended?

Asked by Wando February 12, 2020

60 or 80 grit is recommended

How are these discs attached to the sander?

Asked by Hutch December 6, 2019

Hi Hutch, These ROS sanding discs use Hook and Lock backing to attach to the sander.

what type of sanding discs can I use to rough up concrete

Asked by Mike September 26, 2019

Hello Mike, If you're looking to scuff sand the concrete use a 40grit to 60grit sandpaper. I hope this helps. Cheers, Chris

As pro carpenter, my new go to
I used to use the purple disks from 3m even before HD carried them here. I would get them at my local paint shop. I was paying over $1.20/sheet, but they were excellent. The product was changed and is not that good anymore. I tried the Diablo disks as an alternative. I find the quality to be comparable to what the purple ones now offer, but Diablo 50pk exceeds by far in value. This is particularly noticeable when working with sticky surfaces (stripping paint, sanding epoxies). Diablo is now my go to sanding product.

Diablo 5” sandpaper is great, I get better use from these then other brands. One disc will last longer then using 2-3 disc’s of some other brands, this is why I use Diablo for all my sanding and cutting needs.

Sanding discs worked great stripping old stain off of my cabin. I saved thousands by not hiring a contractor!

Excellent for dust collection.
These are great 5" sanding disks. There's a more perforation through disk which helps increase dust collection considerably. Plus the fact the cost for a 15pack order I find it economically.
Not good
I have been using Diablo sanding discs for the past couple of years. While working on a timber frame I used up my last package. I was stunned after trying this package. I can barely get through 3- 1X2X1 pine boards and the backing starts to peeling so bad I have to replace the disc. I contacted Diablo to see if they could send another package. It's been 2 months and they haven't replied. So I am guessing they aren't going to reply. I have some older packages of 150 and 220 discs from a couple of years ago and they work great. Something must have changed at Diablo so I will look somewhere else.
