Basically I had somebody (a cowboy) come in and re-lay my concrete floor and the screed had the wrong mix. The photos show what I am left with. [The "trench" in the middle of the first pic I plan to fill with latex screed] I have tried to salvage the situation by applying a watered down PVA mix to the floor which seems to have hardened the surface up and stopped it degrading any further. But I don't know what to do now? Will the underlay and the carpet cover up the issue? I was thinking of putting down some latex self levelling screed but will it work or will it be spread too thinly for this? The worse issue of all though is the missus, she won't stop banging on about getting carpet in! Please can somebody advise me...
