Floor screeding disaster?
Firstly thanks to Mike Taylor for the suggestion of slate across the
cavity,and thanks to Michael Mcneil for replying to my question about making a dry mix for screeding. Yesterday, we made the mix, placed it, but I am now wondering if we made it too dry! It compacted in the hand when squeezed, but absolutely no excees moisture was present. I wet the slab four times during the day before laying, and PVA'd 5:1 as we screeded. Even after covering the screed with polythene, the top surface just became dust, so today I went over the screed with a mist sprayer and trowelled the surface. However, it is still suspiciously loose on top. Should the mix have been wetter, or is it normal for the top to become a bit loose as it cures? Is it irredeemable? - am I going to end up needing to seal it or put a self leveler on to hold it together. Or dig the whole lot out :-( Thanks in advance Bill M |
