    I am looking to get into sand carving. I want to know what brand can we get to cut on a simple vinyl cutter?

    I used this stuff once... matter of fact I think I still have it from a couple years ago...

    From what I heard it held up ok. Only good for one go-around though. The mil thickness is up there a bit so obviously test before you cut.

    Sandblasted is pretty thick. It's more like a foam/elastic material than a vinyl.

    If by simple vinyl cutter you mean a cricut or Chinese cutter... It.may not be possible. I'd buy a yard.or two before committing to a roll to see your results.

    Used a lot of Hartco 425. Make sure you get the versions with paper liner if you want to plotter cut it. The plastic liner allows it to stretch and warp, in other words it doesn't seem to cut well on a plotter. If you're sandblasting sign foam get the highest tack and blow off the dust first for best adhesion. even then i use a stapler and staple the small pieces on. If the mask is narrower than the staple you can clean off the area where the staple when beyond the mask easily after it's blasted.

    We never took the time to prime it first because we never had time or available space to wait for it to fully cure and then re-prime the freshly blasted areas.

    On really large signs we would lay the mask down and use spray adhesive to secure a pen plot and then hand cut the stencil. At times this is easier than trying to line up 2 separate masks. for smaller detailed areas on signs like this, we would plotter cut certain components and lay them in later. The trees were plotter cut and the rest was typically hand cut depending on the overall size.

    We also used to weed the graphic on the sign if i remember correctly, and we never cut the signs to shape until after they were blasted. That way the corners don't get dinged up at the blaster or during transportation.

    For glass etching Avery paint mask works fine. I’ve etched lots of glass with it. If you’re going to be sand carving fairly deeply you might need to go to regular sand blast resist. I prefer Anchor. Hartford was always too stiff in my opinion.
