[leekirstdyl]

can someone please tell me what the formula for working out how much sand i need to render a wall. The wall is 35m x 1m, 2 coats at 10mm thick, thankyou

Basically mate at 4:1 a tonne of sand will do 30 square metres but make sure you use plastering sand or you'll get cracks.

Hope this helps mate
