I'm looking for material that can be used as a sandblasting mask on concrete and / or stone. I've found materials from 3M, Hartco, and Anchor, but it seems like most of them are made from PVC. Does anyone know of a laser-friendly masking material that is thick enough for concrete sandblasting?

Thank you!

I think this may be what you're looking for. The product is called LazerMask.

There is a local business in my area that sells a very thin rubber sheet product made for sandblasting masks. I haven't tried it yet but it is supposed to be very durable and suitable for multiple applications. You may also have a specialty rubber type of business in your area, check your phone book...it will probably save you some bucks.

Depends on how deep you blast , products are available from most vinyl sigh suppliers. For anything other than serious blasting the polyester based shiny vinyls are ideal. Almost impossible to go thru and for really heavy duty , double the layers. Its laser friendly and cheapish. The gravestone industry uses blasting masks from very thick paper to rubber (suitable for vector cutting in the laser but a messy and smelly thing to engrave , thus the fine detail isnt available.)
Problem with masks on stone are mainly due to the stuff not sticking well or the middle of letters coming out. The other alternative albeit I havent tried it is to paint the very rough or rieegulat stone with a latex based paint used for tool handles and laser thru it. , might also be smelly and difficult to remove. Just an Idea tho.

I have used the Rayzist product and it works very well under extreme sandblasting conditions. It is quite expensive so there are cheaper alternatives which may suit your needs.
It is necessary to have a smooth, flat surface, and to carefully burnish the masking material to the surface to make sure that there is no bleeding or lifting up due to the adhesive coming loose.
I have used it on optical crystal and on polished granite with excellent results.
