k,400 square trad dash should go something like this,(remember the cement content could go up or down depending on the stength of the substrate!)
scratch coat=@8mm is 28 opc ,110 sand
buttercoat=@10mm is 23 opc,120 sand
stone=128,big pea dont go far!
should be 10% over,price your own admix/lime/waterproofer /bead from the measure
all by 25k bags!

sorry m8 ill explain,a normal semi weighs in at 90 to 100 sq,for this id use about thirty bags of powder to scratch(in your case s+c)maybe a few more to top,that gravel is fat and 25 to 30 stone to throw.
