I have a 40mm floor to lay in an old cottage. Was wondering should I use concrete or normal sand and cement. Is there any need for concrete. what ratio should i mix the sand & cement at if i choose that method I have the living room and kitchen so it only 50 m2 in total. Is there any benifits of using concrete.

get premix fibre screed mate, lifes too short to be mixing screed,
make sure you get a good bond on slab with a nice tacky slurry as its a bit on the thin side mate.

if you need to get the floor up sometime in the future, concrete would be more of a problem.
I have a 40m2 area to lay. Wondering the best size of subfloor. Was going to use 4" stone then 40mm concrete to finish. It's an area with no walls The Roof is held up with concrete pillars. The floor is open to the elements. Just an area for the kids to play. Sand & cement screed or concrete??

I'd concrete it if it's open to the elements
