Robin asks: How many times can the stencil on clear contact paper be used using the chemical method? Thanks Robin J.
Hi Robin, If you’re using the hobby etching cream, then you should be able to use it as long as the adhesive side will last. The actual chemical substance doesn’t really eat the stencil material away. The chemicals mainly eats at glass or ceramic type surfaces.
If you’re using the hazardous hydrofluoric acid, then I am not sure since I don’t use that stuff because it is very dangerous. I just provide some basic information about it. HF acid was more popular a long time ago, and I mainly hear mostly glass manufacturers using it in the industry today.
If you are using carving methods listed here, then you usually can’t use contact paper since it is way too thin & brittle. Sand carving uses very air high pressures that will penetrate through the contact paper. They have special stencil resists called sandcarving resists made of thick vinyl or rubber that is very durable. I hope that helps. -Eric
