Last year laid down a floating wood floor, now i have a problem with
it cupping in a couple of places.

The wood is soft pine T&G glued together and ronseal diamond hard
about 4 coats, looks good apart from the cupping and springy (bounce)
of the planks of wood when i stand on it in a couple of places.
The subfloor is concrete with a vapour barrior and underlay combined.
Their is a gap all way round the edges to allow for expansion.

Is it not customary to paint both sides of such particularly soft
timber to reduce bowing?.

If the planks are only painted on one side they will tend to warp or
pull up as the coating dries.

Or was the timber already pre-treated?.
