Self levelling compound for large area?
Recently we converted our old garage (under main roof) into a bedroom. We needed to raise the level of concrete a fair bit so we had another concrete slab layed over the top of the old one (I think about 5cm thick with reinforcing wire stuff through it and a layer of damp coursing under it). Details are sketchy, I was 9 months pregnant when it was done :)
The slab is quite rough and slopes down a bit towards the window end of the room. We want to level it before we put in new carpet and a built-in wardrobe but unsure of the best way to do it.
We looked at self-levelling compounds but were not sure if it's an option for a room of this size - approx 3m x 6m (~10ft x ~20ft) and for this much difference in the level. Probably go close to a 2cm drop from one end (which is decent) to the lower end (which is really rough).
The good end would just need the odd tiny hole filled (tiny = 1mm ish just for a completely flat surface) whereas the rough end would need about 20mm depth pretty much over the entire end.
What's the best way to go about doing it? Not sure if we section off each area to do it or do a few thin layers building up to the right level?
