Hi everyone,
I have a problem with the floor in my terraced house that I’m hoping someone can advise me on. When I moved in to the house 3 years ago I levelled the very uneven concrete floor in the front room and then put carpet down but have had problems with it ever since.
I used a cement screed to fill in the big dips in the floor and then used self-levelling compound as a final layer to bring it level and flat, but over time it’s become evident that the layers I put down have not bonded with the original concrete below at all - this has manifested itself in a ‘crunchy’ feeling under foot as the top layer cracks and breaks up as you walk on it.
I’ve put off the inevitable for a while but now I’ve decided to take up the carpet, thoroughly level the floor and put down some wooden flooring instead. Can anyone offer advice about how to avoid a repeat of the above with suggestions on materials or techniques?
The room is around 3.5 – 4 sq.m with an undulating floor, maximum height difference of about an inch in places. I’ve taken up the very loose pieces of levelling compound now and found that I laid this very (too?) thick in places, some pieces are over 15mm in thickness.
I've read the main article in flooring and am I right in thinking I need to bring the floor within about 3mm of level with 400 repair mortar, prime with p131 neoprene primer then use a water-based self-leveller to finish it off? I'm assuming the repair mortar will stick well to the floor below it when applied thinly?
Many thanks in advance for your advice.
Tom.
