Fitting semi soild flooring

irishguy

Could anyone tell me how I would go about fixing a semi solid floor to a wooden floor (1st floor). I was recommended (for an engineered floor) to glue the boards together on the ground floor (just the tongue and groove and leave the floor floating). Not sure if this would work over a wooden sub floor with expansion, what do people think?

Don't see any reason why floating floor wouldn't work fine on wooden subfloor, the floating floor isn't fixed to the subfloor so expansion in one won't affect the other.

Make sure the subfloor is flat enough. The instructions with the new floor will tell you the maximum unevenness allowed (usually 3mm over a 3m span). Knock down high nails.

Replace weak floorboards in the sub floor, most semi-solid boards are not designed to support weight, thats the job of the subfloor.

Tighten down any loose boards on the subfloor, use screws instead of nails to avoid creaks later.

A damp proof membrane is not needed on 1st floor but do use the recommended underlay (usually 3mm foam or 6mm fibreboard).

Lay the new floorboards perpendicular across the old floor boards, not parallel to them.

I was just thinking that with movement and expansion/contraction of the wood it might damage the floor. Would be handy if I didnt have to nail down the floors.
