Floor Levelling Compounds

[realtek]

Hi,

I'm going to level a concrete floor, just for smoothing out ready for a celotex floating floor to be installed on top.

Looking at the Setcrete products, Any recommendations between either Latex one or Universal floor levelling compounds?

I've used the latex one before but just wondered what the difference was really as the universal one is cheaper.

Probably be going to a maximum depth of about 6mm in some areas.

Thanks
