For many years my choice of rubber has been the Anchor 116. We go through about a roll a month. The powder they put on the surface needs to be washed off before applying app tape. We've been triple washing and still not getting app tape to generate the transfer. Yesterday I was spraying 3M 77 on the rubber to get the job done. Anyone else wrestling with this?

Rick, I've had the same problem. I just did a test. I gave it a thin coat of shellac with a foam brush. A bit of a hassle having to do that, but it only took a couple minutes. It adhered well, dried quickly, and the tape stuck. Edit: I'm not sure how it will affect the sandblasting. I send it out for that.

I'll try that Chuck. Yesterday was my blasting day and I hope I can go a couple wees without putting my hood on again.

Wash 1 time, let dry, use Lacquer Thinner to do final clean

Perhaps the reason you have not had lots of answers to this question is that sandblasted signs are out of favor with the city folk. I haven't blasted for at least a year. Everybody wants flat cheap signs. I do miss the design freedom that the technique allowed. Now its just vinyl, vinyl, vinyl.

That started happening to me as well although it was quite a while back since I sandblasted anything. I only had medium tack transfer tape and attributed the lack of adhesion to that. Have you tried a high tack transfer tape?
