Hello all, Im after a bit of advice.
We are doing an extension which will create a combined kitchen diner at the back of our house. All the downstairs floors are solid screed (house was built early 90s so should also have DPM under the screed and insulation under the slab I believe). We are going to have a continuous floor covering throughout the downstairs of the house (engineered wood parquet, which can be glued or secret nailed - but cant be installed floating).
The problem I have is that for some reason I cannot fathom the screed in the kitchen is around 8-9mm higher than the other downstairs rooms.
I had originally thought we could grind the kitchen floor back and then use self levelling to make good, but I have been told by a couple of people that removing this much screed in this way would be very difficult/ time consuming. I had originally considered smashing out the screed in the kitchen and re-doing but that would be equally if not more time consuming/ costly I think.
Other options I had considered were either to use self levelling compound on the rest of the downstairs rooms to raise them to the kitchen level, or to glue 9mm ply to the downstairs floors to act as a sub-floor for the parquet.
In terms of cost I think the ply option and using something like stopgap 300 would be pretty similar.
To add to my quandry we are (probably) going to be having wet UFH retrofitted to the existing downstairs screeds, and I am unsure whether a ply subfloor has any downsides compared to compound in this scenario.
Then lastly, I am going to be doing this myself. I have done some smaller areas of self levelling compound using F ball products in the past - although I made the mistake of not using a spiked roller/ squeegee and although the result was OK, it wasnt perfect by any means, so I suppose in terms of getting as flat a finish as I can, ply might be the better option...
Any thoughts/ comments would be most gratefully received!
