Blasting Resist in a Pinch?

Paul Tarlow · Post by **Paul Tarlow** » Wed Jun 25, 2003 8:48 am

I need to do some fairly deep sand blasting this weekend -- but don't have any "real" resist. It seems the only way to buy the stuff is to mail order it -- which probably precludes me having it in time.

Any suggestions on decent alternatives. For this project I don't need (and in fact don't want) crisp lines.

Thanks,
Paul

Hey Paul,

What about "MacTac" shelve covering. It comes in clear. Or duct tape/masking tape.

Cheers,

Bob

You can paint on elmers glue or asphaltum or liquid latex (the stuff used for coating tool handles)

Trowel on a layer or silicone caulking compound and let it dry.

How about a couple of layers of Contact paper. I don't sandblast but I had a friend blast out a couple of bad areas on a piece for me. I just put on one layer of contact paper and all was well when I removed it. She didn't do any thing deep.

Contact Cement works great.

Does the contact cement peel off or do you have to use a solvent?

It just rubs right off. These "liquid resists" such as spray adhesive, contact cement, and rubber cement are for texture. You aren't going to be doing any straight lines, or cutting when using them. They're primarily used to texture an already sandblasted area. Normally, you would resist your blank, bowl, 4' by 6' panel of float, lay out your design, cut, peel, and blast. Then, you would go back into selected areas with a liquid resist. These coatings can be manipulated, and when used in conjunction with sandblasting and acid etching can make an extremely interesting textured effect. I believe Markian Olynyk of Vancouver was the first to discover this. He was certainly the first one using them here. many years a go. He can make amazing effects with this process and paint. Elaborate, multi-panel screens. Brock

Maybe you should look at sign supply houses for the resist if there is one near you. The one I use stocks it regularly. Also you might try sign makers that specialize in wood sandcarved signs or monument makers in your town. They may sell you what you need if it is not much until your resist comes in.
