I have to screed a concrete floor slab. Screed is going over concrete,
not over insulation. Screed depth was supposed to be 60 to 70mm, but
the slab ended up a bit thicker than intended, so in some areas, the
screed will be down to about 40mm thick.
Will a normal dry mix sharp sand / cement be OK at that thickness, or
should I add anything (like SBR etc.) Floor will be tiled.
I was going to use sand / cement in case I need to slightly slope
levels to match floors in two adjoining rooms.
Or should I consider any other type of screed ?
Cheers,
Simon.
