Picture of DIY Replaceable sandpapers for Sanding blocks

In the past, I have bought many cheap sanding blocks on the market. For the most part they work just fine but I have often found that they are either not ergonomically designed and are uncomfortable to hold or replacing the sanding paper is a royal pain in the ass. So after cursing many sanding blocks I decided to it was time to take the DIY route.

Step 1: Choosing a sanding block

After some research on the internet I decided to buy an Anderson Smooth Touch Sander. It is not at all necessary for you to make the same choice. You can easily replicate the process with any other materials like wood block, blackboard duster etc. Choose a sanding block which you are comfortable holding.

Take the sanding block of your choice. I chose an Anderson smooth touch sander 250 mm.

Step 2: Fiberglass tape to protect the base

Now cover the area, where the sand paper will be stuck, with fiber tape. The fiber tape is reinforced with glass fiber threads and is very durable.

Step 3: Double sided tape to stick it all

Next step is to put a layer of double sided sticky tape over the fiber tape. Make sure you use a good quality tape which has good sticking power. 3M is recommended.

Step 4: Finishing off with the sand paper

Now cut a piece of your desired grit sanding paper according to the shape of your sanding block. Stick it on top of the double side tape and your removable sanding paper system is ready.

To replace the sanding paper just remove the currently fixed sand paper and replace with a new one. After two or three cycles of replacing sand papers, you will have to remove the double sided tape and replace it as well.

Your replaceable sand paper system is now ready.Thank you for reading.

I subsitiute rubber cement used for crafts projects for the double sided sticky tape.

Hi klw4025

Will rubber cement glue come off easily ? The sandpaper will need to be replaced after several run cycles.

I've made a flexible long board for sanding boat hulls before. I designed it to use a full sheet of sand paper (cut in half vertically and stick together). I was playing around with the idea of double sided tape but someone suggested just using spray adhesive instead. I bought a can of 3M Super 77 and I just *lightly* spray the back of the paper, let it dry 5 minutes, then stick it to the sanding board (block in your case). When the paper is worn out, just pry up an edge and pull it off. The glue is just enough to keep the paper in place but not enough to permanently bond it to the board. I did that years ago and I still haven't used half of my can of glue.

The trick is using the glue sparingly.

Thanks Jobar007 fo sharing your tip..but unfortunately 3M Super 777 is not available here at my place. Double sided tape is the alternative that is commonly available.

I wonder what is that glue used for some of resealable bags, that could work longer and better since it would be a thinner layer that this double sided tape.

I've tried this before with duct tape and it didn't work out, but this looks much more sturdy!

Hey Jessy

I have successfully sanded a lot of stuff from this particular block..so I can vouch for its sturdiness.
