Spray Adhesive?

So I just tried doing some sanding on my new granite surface plate. I went out and bought some 3M Super 77 spray adhesive. It seemed to hold the paper in place on the slab but it seems like getting the residue off is a bit of a problem at the moment. I scraped it with a razor blade and got most of it off but there seems to be a bit of residue that is stubborn in coming off.

Do I have the wrong adhesive or is there something else I should be using to get the glue off? I know natural stones and whatnot have a limited amount of cleaning detergents that should be used on them. So what is the best way to go about using the slab for sanding?
 
The best thing to take off the old adhesive is lacquer thinner. The best way to use a flat surface for sanding is to glue on a piece of 220 or whatever, and then just setting the sheet you are using on this piece with no adhesive. Then there is no need to mess with the glue when changing grits.

LOL of course they're going to recommend one of their own products :)

I would say Goof Off or Goo Gone would remove it (those are citrus based too :) )
 
I use 77 on my surface plate also, and I use a paint scraper to get as much of residue off as I can, takes more than one pass, then if I really need it clean if I am going to use 1000 grit or something like that I hit it with the carb cleaner and wipe with a rag. most of the time the paint scraper works good enough for me.
 
the 3m citrus spray is freaking awesome for any type of glue or caulking i ues it at work alot
 
Goo Gone- I use it on my surface plate and my disk grinder to remove glue residue....Work very well and I can get it at HD......:D
 
I believe he means VARSOL , which is a sort of universal solvent used in auto shops and garages. (Varsal is a Chinese chemical and laboratory instrument manufacturer.)
 
I think the key is to not use too much adhesive. A very light coat, sprayed from a bit of distance onto the paper and allowed to get tacky before putting down holds well and also comes off cleanly. Any residue wipes right off with a little WD-40 and a paper towel. At least that's my experience.
 
I just spray my surface plate with windex and lay the paper down.The capillary action of the liquid works just fine and no adhesive.

Mr. BE has it right I think. A very light mist coat of adhesive sprayed on the paper, not the plate, is the way to go. Thats how I made sanding blocks in the past for doing minor bodywork.
 
You can also use a heat gun to loosen the glue and then put down new paper, I just spray the back of the new paper very lightly. More reciently I have been using a low grade school supply spray the one with the cow on the front, holds fine and can peal the paper off pretty easy.
 
The super 77 is a pretty permanent spray adhesive. Try looking for the Duro. Spray the back of the paper let it dry and then set it in place. It should hold but then peel off without much residue pretty easily.
 
Since I have run out of carb cleaner I have moved on to gasoline.

Kerosene should not stain or leave a residue, it does not have wax in it like diesel. To be honest I wish I had kerosene to use instead of gas.
 
what about acetone? I use it to clean up just about everything, but a heat gun will help as well if you are trying to scrape it up. just don't use acetone with a heat gun if you value your eyebrows.
