your walls are 13metres high do you live at strangways

their is a render screed estimator at the top of the building forum which will give you your quantities.

Cement usually fills the voids in the sand in its mixed state. You have 30m x 13m high(jesus) = 390m2 x 0.032 (assume 16mm thick - 8mm x 2 coats but double up cause relative density of sand is about double). In fact ignore that, start with 5 ton 30 cement and see hoe you get on.

I think he means 1.3m. Get 1 ton and 6 cement and see how you get on.
