I understand from previous responses that ideally they should be laid on battens, but is it possible to lay a T@G wooden flooring (probably just standard new pine floor boards) over a concrete base as a floating floor by simply glueing the boards together? The main reason for this is to avoid having a step.
If this is Ok is any underlay required such as plastic sheeting to act as a moisture barrier, although the concrete has been down at least 20 years so I assume its dry! Also, to reduce any noise, would it be sensible to lay some type of cushioning material such as the stuff sold for laying under laminate flooring.
If the floor boards have to be fixed to the concrete, again to avoid using battens, can you simply screw them directly to to the concrete. I appreciate that this will be a tedious job, but is it at least feasible.
Any advice gratefully received.
