I am going to be self level the floor prior to wood flooring.
There was a patch that had been done before, it had a few cracks and sounded hollow, so I’ve taken it up, it’s chunks of around 25mm that came up.
Probably be just under a metre square when all dug up.
I noticed that the cement that came up had not adhered to the concrete sub floor (the hollow sound)
I was going to damp it, then an sbr slurry, while tacky fill it in, should I used a 3 to cement mix (sharp sand) and a bit or sbr
Or should I do a concrete mix, if so can you tell me what to use and mix? Thanks all.
