I've got some 80mm x 18mm solid oak flooring that I want to fit in my
living room. The house is around 8 years old and the floor is
presumably concrete with some 'black' stuff over the top.

Browsing around the net and groups for the past few hours has left me
more confused than ever, hopefully someone here knows enough to answer
a few questions....

The instructions say I can glue it directly to the concrete floor. Is
this true? If so how does the glue allow the flooring to move enough to
prevent it buckling or opening up?

If I can glue it - B&Q sell 'parquet' glue, is this what I use?

Would I be better putting some sort of underlay down and floating the
floor - perhaps glueing the t&g? (Someone mentioned an underlay that
was 'sticky' - although I've been unable to find anything like it
since).

As always, any advice, links etc gratefully received.
