A couple of years ago we had an extension built. The screeding in one of the new rooms (5.5m x 3m) wasn't very good so I got the builder back to improve it with some "self-levelling" screed. I just checked it before laying some flooring and there are several areas that are 5-6mm low/high
- too late to get the builder back so I need to sort it myself.
I realise that "self-levelling" screed is a misnomer and I've never enjoyed using the stuff before on small areas. Is there a "standard" way to tackle a job like this where there's no reference?
It looks like the high-spots were created when they latex'ed it; is it possible to sand-down the high spots?
