I'm referring of course to using sandpaper adhered to a flat (1/4" float glass, granite block) surface. My question is how to adhere it! I currently have plain-jane 3M SiC paper, so "get PSA paper" (besides being expensive) won't be viable until I've used up my current stock.


Short of that, what do y'all suggest? I'm hoping for some sort of *temporary* spray adhesive, but I've also heard that water and capillary action will produce a usable adherence, and that a lot of people use normal spray glue and just scrape it all up when they re-adhere.


Thanks all!
 
you could use rubber cement to hold it in place. just coat the backside of the paper and stick it in place.
 
Walmart has 3m spray glue adhesive that works really well. You could then just take a razor blade to the adhesive that is left on the glass or granite after you pulled the sandpaper off. And scrape up the adhesive with the razor blade. Cleans it right off.
 
I found some repositionable/removeable spray adhisive at a craft store. I think it is a Krylon brand, I found it at either Michaels or Hobby Lobby.
It holds well enough that the paper doesn't slip, but pulls off without tearing.

You might look for a photo-mount spray adhesive. You could also try rubbing something tacky like beeswax or rosin on the back.
 
I've just used water, but I was tuning a low block plane. Not quite the same set of forces, but it worked fine. I was going from about 150 to 800. Glue would have made it into a PITA.
 
3M Feathering Disc Adhesive Type II

Part # 08051

is an excellent adhesive for bonding cloth or paper backed abrasives to rubber, plastic, metal, glass and other back up pads.

The spray can of this material is no longer offered.

Usually stocked at automotive body and paint stores.

Does not delaminate the paper when left on overnight.

A different product (not the same as 3M 77)
 
I used WD-40 (sharpening a plane blade). Sprayed the back and rubbed it down. Had the added advantage of working as a lube for the metal particles.
