I have a rather wobbly concrete floor which needs levelling before I lay reclaimed parquet on it.
It's too deep for floor levelling compound, so the plan was to lay a concrete screed. I've around 20sqm to cover with 40mm of screed at the deepest points, I reckon just over half a cubic meter in total.
Does anyone know how I can work out how much sand/cement to buy for this (I'm assuming a 3:1 ratio)?
many thanks,
Ross
