Can I install vinyl flooring over concrete?

How thick should screed be?
The optimum thickness of a sand and cement bonded screed is 25–40mm, an unbonded screed should have a minimum thickness of 50mm, whilst a floating screed should have a thickness greater than 65mm for lightly loaded floors and 75mm for more heavily loaded floors.
How do you bond screed to concrete?
