i've been asked to construct some raised rendered panels for signs on the outside of a pub, but the customer wants to know whats the thickest i can do, i was thinking of using a normal stop bead but i think he wants pretty deep, any suggestions as to how thick i should go, i said 20 mm or so should be fine as i dont really want to start battening the wall out with 3x2 lol...... and maybe mesh it first if wall is a bit ropey so theres less chance of panel hitting someone on the back of the head while they are waiting for a taxi on friday night.:RpS_biggrin:
