25 kg of sand mixed at 4:1:1/2 sand cement lime will cover new work @ 10 mm thick so 1 tonne will cover up to 40 m2

A mix of 4:1 should cover on average 35m2 which is about the size of a garage I rendered last year.

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.
