What is this screed? How thick is it? Those I've used to a depth of half
inch you can walk on in 3-4 hours with no risk of subsequent cracking.
Expensive stuff over a large area though.




1/2" aint a screed. thats a skim!

Screed is generally 3-4" You can walk on it after about 24 hours, but
full strength and shrinkage builds up over a week or two.
