I find myself in need of some expert advice.
I have to sandblast some rather small copy and a logo on the face of a 2000 lb. piece of granite. I have sanded the face to a fairly smooth surface....unfortunatly it is not as smooth as I would like...it is still very irregular. My question is...how do I keep the mask on while it is bieng blasted. Any tips?

Jackson, I would try some 3M Super 77 spray adhesive on the back of the sandblast mask, but "mist" it on. In fact there is another one stronger, I think it's Super 98 or something like that. Like anything new try a sample piece. Or my next thing I would try is calling a tomb stone place, and see if they will give a little info.

Jackson.. I blasted a rock for Bruce N Dan for a wedding gift. It was a raw,natural rock from a garden supply store. I used Anchor mask...and I glued it on the rock with Barge Cement....this is a contact cement used by shoe makers.We used it years ago to glue carpet on the soles of our hip waders....for fishing in Adirondack trout streams..it keeps ya from slippin on the algae on the stones. Back to the project..... After the mask was applied....I stomped it into the nooks with a rivet brush....it stuck like iron.Blast away....

Thanks for the fast replies guys....I have thought about using a good glue...however...how do you remove the glue? I failed to mention that I need to paint the letters and the logo before removing the mask....que?
Hola Cisco...Que pasa?

There is a glue made for what you are doing,Jackson.Try contacting one of the local monument dealers or sign suppliers.Back in the eighties when there was a monument dealer next door & he would spread the glue on the stone then burn it to flash off & set the adhesive then apply stone mask to this. ask your supplier about the availability of stone blasting mask it has a much stronger adhesive than normal wood masks.

There is also a filler specifically for this use. The biggest problem I've encountered was moisture in the rock. The friction of blasting generated heat and moisture came to the surface causing adhesive failure. I found a coat of shellac prior to applying sandbalst resist solved the problem.

That granite is hard stuff. Anchor sells a filler made just for stone ( reminds me of First Step) which gives you a nice smooth surface for the stencil to adhere to. Only thing I don't like about it is that you're supposed to wash it off with gasoline after blasting. YUCK!
Mr. Boone's method sounds much safer.

Jackson..there is a product by Anchor called Stencil filler. I use it whenever I have a sandblasted sign to blast. It helps make the detailed work not be blasted away by the blaster. Sometimes I even 'paint' it around the edges of the cut letters to help with adhesion. Sounds like a cool project. My Grandpa used to be a headstone maker.

Thanks to you all for your help. I was going in the right direction but couldn't figure out what to use to glue the mask on...and what paint to use....so...now I know! Thanks again.
