many a building control inspector wouldnt have it any other way matefancy breathable paper? (expensive) and expanding metal lathe mate you can buy it in rolls sheets or rib lathe with ribs running horizontal to keep it off the wall slightly, you can buy eml in galvanised or stainless , not sure about rib lathe though i think its stainless only mate
if you use both the paper still allows the wall to breathe and the eml gives you a key ............slightly over the top but i cant think of a more fail safe way to over render
I only use plastic ones when im wet dashing but only as a guide on the externals. I use them round the windows work up to them and rub up the reveals, On dry dash i use a hard arris,do you still use angle beads when using finishes like rough cast or pebble dash. cheers
