Groundwork & Foundations Question

Levelling concrete floor.

I recently laid 4 inches of concrete in my extension, but there are some areas that could do with some self levelling compound. What i want to know is, how long do i have to wait for the concrete to dry before i put self levelling down?? Does it have to be %100 dry??
Any help would be appreciated. Thanks.

If you are using a water based self leveling compound, you do not want the floor to be too dry, the way i level floors is to completely soak the floor first, using buckets of water or even a hose pipe, once the concrete has stopped absorbing water ( look out for the tell tale bubbles ) then sweep up the remaining water puddles and then lay the floor level compound, this will allow the compound to smooth its self without drying out to quickly by the dry concrete, remember self level is a lie, it should be called self smooth you will have to fill in the hollows with the compound it will not find them for you !!
Good Luck!
