    Spray on Adhesive that lets go when done...?

    OK, I think that someone like 3M makes this kind of product, you spray it on, to say sandpaper, then stick the sandpaper to something, when done, the sandpaper just peels off.....?

    I guess a spray on Pressure Sensitive Adhesive.........?

    I think the one I want is #72, but when I look it up online, it says "Obsolete" on the 3M homepage.....

    I have the 77 stuff, but it is NOT PSA, as you need a razor blade to get that stuff off!

    I'm thinking of making my Disk sander disk out of thick MDF, and coating it with some sort of finish, then spray on the PSA and use normal sandpaper....?

    Anyone use this stuff?

    Cheers!

    Well one of the reasons I was thinking of using the spray and just sandpaper is the PSA disks here are about $16 each! If I buy in a pack of ten then they drop to about $12 each......

    Can of spray adhesive and some sandpaper......

    Cheers!

    This might be what your looking for. It is low tack and might be to low for a disk sander. I use it for holding sandpaper to the granite plate for scary sharp. But you might want to search for low tack and see if that come up with something better.

    Thanks Tod

    Something like this huh?

    12" Cloth Sanding Disk Pack of 25 $85.95

    If they will ship to Japan, without shipping that is $3.44 a disc..........??

    Maybe Alex and I can go in on a few packs of discs.

    What are the recommended grits for a disk sander?

    Cheers!

    Stu,

    I am pretty sure that this is what I have used: http://www.idealtruevalue.com/servlet/the-47236/Detail
    I don't know if you can get Duro products over there or not. I was using it on an old roll of 500 sheets that the glue had dried up on for a DA sander so it might not work as well with a disc sander, but it might.

    I still have a can of it so will test it today. I should let it set for a few hours and see if it still holds and will release.

    I'm with tod. If you can get the cloth backed psa disc for a reasonable amount I would go that route. They are tough as nails and will last much, much longer than regular sandpaper thus a greater cost is justified.

    I just pulled off the sandpaper that I glued on with Duro and it was still holding good after six hours and easy to peel off.

    Hopefully tod's deal will work out for you.

    Hey Stu,
    We use #77 for keeping sandpaper on glass. It comes off the glass easily with a little simple green. Maybe another approach would be to put a washable surface on your disc, maybe some formica or something...
    Don't believe everything you think!
