Questions and Answers for DIABLO 5 in. 220-Grit Universal Hole Random Orbital Sanding Disc with Hook and Lock Backing (50-Pack)

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

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

A:  Hi Mike, we recommend using a low grit sandpaper (40-80 grit) that can with sand the toughness of concrete.

A:  Yes they work fine for wood and a soft metal like aluminum

A:  yes.

A:  They will work on aluminum.

A:  Hi GKerr! Yes, these sanding discs can be used on aluminum. Thanks for the great question!

A:  You can sand anything, but it depends on the type of material you’re attempting to sand. I really need more info from you, in order to provide more specific information, e.g. material to sand, type of finish, what is the issue(s).

A:  Yes you can but it depends on what you are trying to fix. If the wood on the deck is greyed or has something like Thompson's waterseal stain on it that has started to peel off, then you would be better to use a pressure washer and some deck/wood brightener instead. This will get the wood back to a natural finish quickly so that it can be refinished with stain or sealer and you may not need to sand it at all. If the deck wood is very rough, then I would recommend using a heavier grit like a 120 or an 80. 220 is a bit too fine for a deck and I wouldn't go higher than 120 otherwise you will spend a lot of time with a fine grit like 220. If you have to sand the whole deck and it is very large, you would be better off renting a floor belt sander from Home Depot. Before you use the belt sander however, you will need to make sure that all the screws or nail heads are below the surface of the wood otherwise they will tear up these pads or the pads on a floor sander.

A:  Yes, but being that small, it will take you a while.

A:  I used this on the top rail and had it on a sander with a vacuum collection port . It worked great and was very clean . For the decking itself rent a vibrating floor sander from home depot's rental department. I tried striping with chemicals and small Sanders and it was not very fast.

A:  Yes. You can sand a wood deck with these.

A:  yes it will work however depending what your sanding I might start with 80-Grit. Now on the other hand if you have a large deck and its not just a spot treatment . I would Rent a large floor sander as it will take some time and many 5 inch dics to get the job done with the small sanders. We have done many deck refinishing projects and usually use a product as the 5in disc for railings and spot work. Gook luck and wear a dust mask.

A:  yes. it can sand a deck but sure would take a long time to accomplish. These are more for 'shop' projects.

A:  I see no reason you couldn't sand a deck with these. I hope you have a very small deck. These are only 5 inch disks and do great for small sanding projects but I can't imagine using them for something the size of a deck. I would suggest renting a floor sander instead but, if you're serious about using these, buy LOTS of them and expect to be working on it for a while.

A:  Hi Josh! Yes, you can sand decks with these discs.

A:  Nope, no glue required! You just have to place it on the pad of your sander and it should stay on it, make sure that the holes are lined up. If sand disc doesn't stay on the sander's pad, if the disc doesn't wanna stay on the sender's pad you might have to replace that pad

A:  I don’t believe there is a trick, but I have found other products like 3M and MasterPack stand up to the job where Diablo products don’t.

A:  There are two types available for purchase with different locking systems. Check you product to verify it is correct

A:  The Diablo discs are not as forgiving as other brands. I have had a few fly off when there was some sawdust between the disc and the pad. When I apply them I bang my fist on them a few times to make sure they stay on. I beat on them pretty hard especially on the edges with my artwork projects. However the price being half of what the other brands charge is very forgiving for me as I go through a lot of them. JJK

A:  No, mine worked very well with my Dewalt sander. I did both horizontal and vertical surfaces without a problem. Still sticking well when time to replace.

A:  I've been using these discs with my Dewalt random orbital sander for a couple of years and have not had this problem. I assume (1) you are lining up the four large holes in the disc with four of the holes in the bottom of the sander, (2) the face of the pad of the sander is not clogged up with sawdust, (3) the dust bag is cleaned out, and (4) the grit side is facing out, right? Those are the only things I can think of that could contribute to the problem.

A:  Normally when this happens with our Ryobi sander, it is because the sander's backing pad is worn, or if you've been using the sanding pad for a while it is because the hook and loop backing has started to clog with dust. The set of Diablo pads we bought had a 'bonus' black hook & loop pad in it which attached to the existing hook and loop pad on the sander and improved the adhesion of the sanding pads dramatically on our sander.

A:  I used them on my Roybi sander all the time. Maybe one out of 50 hasn't stuck to the sander, so not an issue. I do wish the pads were 1/8 inch bigger to cover the edges with a little overlap to be able to tilt the sander in sand within a groove or on the edge of the item being sanded.

A:  I use a dewalt and rigid sander and they hold fine so might be your sander

A:  We've been using this brand of sanding discs for 5 years now and go through 100 discs about every three weeks. We sand a lot of pine and while they do a good job of sanding, we are beginning to see problems with the attachment of the disc to the sander. We are very particular to line up the holes, so that's not and issue, we are very good about getting the pad to attach solidly to the sanding disc and buy new pads regularly. Since we sand for hours at a time I was concerned that the heat from sanding was the problem. Yesterday I replaced the two pads on two sanders with new ryobi pads and the sandpaper still wouldn't stay attached. I went to walmart and bought some of their sanding discs and the difference was night and day, couldn't hardly pull the walmart discs off the pad. That's the way the diablo pads were when we started using them several years ago, but now days they are very inconsistent. I'm working through two 50 packs right now and will get about 10 minutes out of one before it goes flying across the shop and won't reattach. Time to start buying the walmart discs I guess.

A:  Cloth It is pretty tough. Grit stayed attached and only had to change the disc when the lacquer finish I was sanding became full of globs of the lacquet

A:  The backing of this item is paper.

A:  The grit is bonded to paper and there is a fibrous material on the backside of the disc that grips to the sanders pad. If your asking if it is a pressure sensitive material or a bare paper back where you have to apply adhesive the answer is no.

A:  cloth

A:  It is a fabric. It is the fuzzy side of hook and loop.

A:  When the sanding grit wears off, the pads have a paper type base however the backing is a nylon type fuzz which is the 'loop' in the hook and loop Velco type attachment method.

A:  cloth loop material

A:  The backing material is fuzzy cloth. Similar to Velcro

A:  It is similar in concept to a ceramic brake pad where the addition of the ceramic material help it wear better and more consistently/evenly. Having used a lot of sanding pads over the years, these Diablo pads are the best, great value for money and last a lot longer than other brands.

A:  I assume (that means guess) that it is part of the grit on the paper. JJK

A:  No, its not a full ceramic blend on the face of the disc. As you sand the particles fracture/break to expose a fresh edge to help remove materials, a full ceramic pad would just clog up and wouldn't renew.

A:  Diablo discs are the best Home Depot sells. The backing last longer than other brands. Which means it stays on the pad longer. I have tried cheaper brands and the disc prematurely will not stick to the pad after a short time. To answer your question - I have no idea but - they work great for stripping - sorry - your question is better answered by researching the composition on the web. A ceramic is a non-metallic solid material comprising an inorganic compound of metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds.

A:  The sanding discs have a longer life

A:  Hello Anthony, Thanks for your question. These discs are a premium ceramic aluminum oxide blend. This allows for proper break down of grits during sanding.

A:  These discs are composed of a premium ceramic aluminum oxide blend.

A:  if its a hook and loop and holes line up yes

A:  Yes, the hook and loop discs work great on the Makita orbital sander, as long as your backing pad on your sander is in good shape.

A:  yes

A:  Works with any 5 inch orbital sander that has the hook and lock feature.

A:  Yes if a 5" orbital sander is used.

A:  60 Grit was the coarsest I could find in stock at our local Home Depot. That being said, it worked fine for roughing up some Behr epoxy garage floor paint that had been used to paint concrete on a covered porch and the new paint went down fine.

A:  never seen it 60 is the most aggressive i have found

A:  I don't know that I have ever seen any sanding discs that weren't an Even #, like 40, 60. 100, 150, 220 and so on. I guess you might be able to google it and find out, but I'm not sure there is.

A:  No, 60 is the lowest grit Diablo available

A:  40 grit should be available but in a smaller quantity package

A:  Ron - Thank you for your question and interest in Diablo Abrasives. We are currently working to expand our Grit range online at Homedepot.com. This will include a 40G option. However, our 60G option will perform similar to many other 40G options in the marketplace. This is due to the unique Ceramic Blend grain we use for our abrasives. Hope this helps. Thanks!

A:  The grit should be determined based on the stage of your project. 80 grit would be for your first sanding, and go up from there in steps until you reach your desired smoothness. Depending on my project and finish type I go with 80, 120, 220, 320 and 400 grits to get the desired finish I also change from random orbital to a palm sander for all grits after 120 grit. I hope this was of some help

A:  On the package it states what grit to use. For fast removal use 80grit or lower, for finishing and final sanding use 100 or maybe 120 up. I all depends on your needs, The info on the packaging can help you decide or stop an employee in the tools or wood section. The employees are a great resource.

A:  this grit(80) is for rough sanding to remove medium gouges and quick removal of loose paint and wavy grained wood. Though you will have to progress to 100 grit, then 120 for smooth sanding. So it depends on the job.

A:  the higher the number to finer the grit

A:  The below list should help in selecting the right grit for your project: 40/60 - For fast leveling, shaping, extra heavy removal and stripping 80 - For leveling and heavy stock or paint removal 100 - For moderate stock removal and sanding preparation before paint 120 - For light stock removal and final sanding preparation before paint 150/180 - For removing minor imperfections and initial sanding between paint/stain coats 220 - For final sanding and surface preparation for stain/varnish.
