Hey Ben,
Yes, I've recently been doing sandcarved stones and wood signs. I use the Hartco 25mil rubber. I bought it from Beacon. It's good stuff, I don't have any problems with the masks lifting off while blasting.
I cut the mask with a Roland CM-24 cutter. It's not really the best cutter for thick material, but it gets the job done. I have an Ioline I/S-85 that I plan to use, but it needs to be repaired first (not cheap). I do my design work in Corel X4.
After I mask a rock I usually duct tape it outside of the rubber masked area. I use a medium tack duct tape so its not a PIA to remove later.
After blasting, I blow off, then rinse the rocks before with the mask still in place. Finally, I paint it before removing the mask. Peel the mask, then call it good.
For wooden signs, I usually paint the blank first, then mask. Then blast off the painted areas where I want wood exposed. Blow off any lingering abrasive, stain or paint the exposed wood, peel the mask, then clear coat the whole piece. Works great.
I'm currently only blasting small signs. My blaster is only a Rayzist 1924, which is pretty small. I hope to have a blast room within a couple of years though. Then, I'll do large signs.
