It all depends on the brick work for your scatch coat any bad brick work should be filled in or replaced and give it a good brush and wet it down with water before you aply upva a ton bag should cover 35s2 meters for the scratch coat and 42 for the top coat and a good spred will not have any wastage as it all go`s on the wall


This all depends on thickness and what you are rendering on such as stone, block or brick, plus how much wastage you have, I work on 30 square metres per bulk bag.
Hope this is of some help.
