Ok, not paving related, but worth a stab..

I have to render a wall that measures 2m high by 2m wide. So not very big.

I think the render needs to be around 1" deep.

Any idea how I calculate how much cement and sand I need?

Let's say the wall is 2m x2m x 25mm render.

How much cement?
How much sand?

I am assuming that the cement is that in the plastic yellow bag that already has a plasticiser in it.

Cheers if you can help.

Calculate the volume; add 30% for wastage (rendering is messy and wasteful), and then use the calculators on the main website to determine quantities of sand and cement.
