I have a wall with a Tyrolean finish (by Protectacoat). The finish has lost it's bond, due to the walls being painted.

Aparently Tyrolean does not like PVA or painted brick.

My question is this:

Is there a type of scrim I can fix to the wall, in order to bond Tyrolean to. I was thinking of using Sandtex Cullaplast!

Any ideas.
