What stencil do you use on the Sand Stone??? I used the Anchor with the filter glue... It seems to be pain in the butt... I also ordered the Hartco 425 material, but the sandblast takes it right off... Please help... I want to do more sandblasting sandstone, but everyone of the job we did comes out crap... Fusterated???
I can't stop doing the sandblasting stones... My father has beautiful 72 acres of white, brown, orange, pink, and gray sand stones, and it would be great if I can get it right...
Thanks for helping me out here... Letterhead Rules

Jamie, Sounds like what you need is slick surface for the stencil to adhere to. Isn't sandstne kind of rough? Maybe like, say, 80 to 100 grit paper? Anchor makes a filler that you coat the stone with(reminds me of First Step wood primer), let it dry, apply stencil and blast. When you're done you can wash it off with gasoline. Sounds super nasty to me but it's the only thing I know of right now. I'm very interested in this as well and would love to get my hands on some sandstone.
Hey, I wonder if First Step would work? Then you could just paint over it after you remove the stencil or lightly blast it off. I would try that. I'm sure Anchor also makes thicker stencils made just for stone if you need it.
I have blasted both marble and granite with Anchor and Hartco stencils. Seems like the Anchor held up better but both of them will burn and disintegrate if you hold the nozzle in one place too long. You want to use the stencil with aggressive adhesive for stone and both Anchor and Hartco make it.
Good luck, Have fun!

Well, thanks... yes the sandstone is rough, just like sand... It seems that Anchor works better, but I hate the glue filter... Sometime they are hard to take off... I used De-Sol-It and it pretty much take the glue off good...
Now with the hartco, I called the company and ask them about their products... They told me it works on sand stone... So I order one to give a try.. Well, it stick pretty good, but if you have a small pieces in it, they just go off??? Then they said that you can't use glue on the stencil??? Wonder why???

Hay guys.. Put a coat of whatever clear you have layin around the shop on the stone.... Then glue the mask on with Barge Cement...or other suitable contact cement. Stomp the stencil down with a rivet brush..let it dry a while..then blast. After you're done blasting..you can remove the clear with a light blast back away some..dust the blast till finish is gone.this will freshen the stone and make it look brandnew. Wayne....the lakeshore here is strewn with hundreds of tons of sandstone. All polished and rounded by the pounding surf of eons...all colors..lotsa red we made a beautiful sidewalk out of em....drive yer truck up next fall n gitcha a load...

Michael, That sounds great. All we have here is iron ore and limestone. Ever see the movie "The Long Long Trailer" with Lucille Ball and Desi Arnaz(sp) where, on their honeymoon, Lucy loaded the travel-trailer with all them boulders? That's gonna be me.....and a couple of them big New York 10 point bucks too.
Thanks

I rinse the stone off with water, after it dries blow it with air , then I always wipe down with lacquer thinner (don't rub hard to pull up any sand) before applying Anchor #116 (high tack) sandblast stencil. I squeegie first, then roll it in both directions.
I don't normally do letters smaller than 3/4". When they are this small, I usually use a font without thin lines.
Another tip is to cut sharp points off of letters like V, W, M, A, etc. Dont worry that you are squaring it off a bit, this will give you clean, sharp edges. (more sticky surface holding the stencil to the stone)
If the stencil starts to blow away while blasting, I usually doctor it up with 3M 77 spray adhesive, follow the directions on the can. This is also a warning signal and at this point you may decide the blast is deep enough!
Ahhh, the insides of letters; They can be 'little' monsters! Last week I was blasting 3/4" letters into patio stones and lost the insides of a couple of A's and 4's. I handcut fresh stencil into the shape of that tiny triangle and applied a dab of Elmers Wood glue, and gently placed it into position and let dry. After painting, it was no problem to remove and left the required 'image'.
Before painting, blow air across the piece, in different directions. You will notice the areas that need adhesive. Here, I usually use the 3m77 spray adhesive, but I'm going to experiment with the wood glue since it came away so clean. The adhesive spray leaves the glue residue and is sometimes difficult to remove. Also, when the stencil has had a hard time of it, I like to use an airbrush or spray paint. (less opportunity for bleeding edges) I prefer using an airbrush so I can get up close and 'baby' the areas where the stencil lifted during the blast.
I remove the leftover adhesive by rolling it with my clean finger, sometimes a little facial oil helps. When all else fails, I use lacquer thinner and a rag.
Hope this helps, Cher.
