To make a screed of 5 to 10 cm on joists. Can you give me the proportions sand and cement, should it be armed with a tiler fence, liquid or barely wet, and put on a polyane. How long to dry before sticking Lino.
I can not see what you mean by "a screed... on joists". The joists are the pieces of wood placed on the joists and receiving a wooden floor... A screed is a layer of mortar 3 to 5 cm cast on a concrete slab. It is dosed at 50 kg of cement for 50 l of sand.
