Hessian cover for copper piping

Furn462

I'm having my bathroom plastered this weekend and the plasterer came to have a look at the room. He commented on the new piping where in a couple of spots it protrudes from the plaster boarding. Apparently the plaster finish will corrode the piping if applied directly onto it. He suggested a hessian type cover that you put over the pipe work with some bonding on top, onto which he can apply the finish. I've had a look about but can't seem to find this product. Anybody know what this product is called?

Thanks.

Any kind of lagging will work. In this case it's just to stop the plaster reacting with the pipe. You could use duct tape...
