I have a room with a sand/cement screed over a concrete sub base floor. The whole floor is uneven as the room has been extended by previous occupiers. I intend to lay a hardwood floor which is recovered solid oak previously laid in a bituminous adhesive. Firstly, will I have to clean the previous bituminious layer off the back of the recovered flooring prior to laying it or is there a suitable adhesive that will adhere to the bitumin layer and the sand /cement screed? Hopefully the final sanding will take out any discrepancies in finished height.
Secondly, I intend to break out the existing sand/ cement screed and relay it level and also to reduce the floor height to accomodate the wooden flooring. I am concious that this type of flooring can be cold so would I be better off installing a floating insulated wooden subfloor to attach my oak floor to instead of replacing the sand/cement screed? Alternatively could I install an underfloor heating system to take off the chill of a cold floor ( i'm not too keen on this option bearing in mind expansion / contraction of the wood with moisture content). Thanks in advance for any advice you can provide.
