I wanted to try sticking my sand paper onto my sanding block without holding it by hand but the spray adhesive I've had haven't worked so what are some that others have used?
thanks

The 3M sandpaper they sell at Home Depot has a grippy back. Works great on a wood block.
 
Sorry, the feathering adhesive is in tubes. The spray I use is #77 spray adhesive.
 
There is a "How to make a sanding block" Video by Gough Custom on UTube. Don't miss it. Make up a couple and sell me one.
 
Did you let the spray adhesive dry before trying to stick it? The spray I use is like contact cement, it has to get tacky first or it will not work.
 
I use an aluminum Great Planes sanding T-bar and the 3M spray contact cement sold locally at Wally-world, Woes or Home Despot. It actually is too strong and if I don't spray it lightly enough I will tear the paper when I try and remove it. I clean the face of the sanding bar with acetone to get off the residue and shreds of paper. If I did this after each use, between pieces of paper, it would probably help but I usually just do it when I get done for the night. My other sanding bar is a 7/32" piece of 5160, use the same procedure. For the wooden sanding stick that is padded with a thick chamois cloth, I just wind the paper on.

Of note, there is an Australian maker that occasionally posts on here and he does something interesting. He secures a whole piece of paper to what looks like a saw horse using spring clamps. Then he moves the blade against the paper. Combine that with Nick's radiused edge plunge line dialer-inner and it might be an even more useful system.
 
double sided carpet tape -- I've used it to attach a turning blank to the sacrificial plate on SWMBO's lathe, so it should work fine for a sanding block.
otherwise 3M #77 or #99 oughtta do the trick. spray both items, wait a minute, slap them together.
 
Don't do that if you want to change the paper. Just spray the block lightly, and wait until it is only slightly tacky before applying the paper. That gives just enough grip to hold the paper to the block, but not enough to permanently adhere it. Peel the paper off when a change is needed, and the block should still be tacky enough for several changes of paper. If it gets so it doesn't hold good, either clean it off with acetone/mineral spirits or just give it a quick spray of the adhesive again - and let it tack up before applying new paper.

Some folks spray the paper instead of the block, and that works good, too. It makes the paper sort of PSA.

For a little more than the regular price of sandpaper, you can buy it in PSA rolls. This makes paper changes merely peel and stick. If you do a lot of sanding, then this is a time economy method worth the extra cost.

This.

Buy some mineral spirits - occasionally you'll need to soak the spray tip in it, if you don't clear the tip after use. Not a big deal, until you're in need of it and none comes out!!!
 
Our local NAPA sells feathering adhesive in spray cans. With it you spray both sides and can still peel apart to change paper, just spray the new paper to stick it on. Jess
 
Wrap the paper around the block...

Take Orings and put on both sides of the block to hold it on.

Then you can remove worn paper quickly without having to screw with glue every few minutes
