Laminate floor vapour barrier
 

Hi, I'm just putting in a wooden laminate floor over concrete (ground
floor) and was a concerned about a damp proof membrane. I've taped a
sheet of plastic to the concrete for a day or two and there is some
rising damp. I've been told by separate sources that it's fine, and I
can just use a standard plastic vapour barrier between the concrete and
the laminate, and that it's not fine, and I need to coat the floor in
polyurethene three times before laying the vapour barrier. If anyone
could shed any light I'd most appreciate it! Thank you. Sam

We had the same issue - laminate on concrete gound floor in a Victorian
house - someone recommended a special underlay but sorry I can't remember
its name - it's blue with ripples on one side and must go a certain side up
and taped together with special tape. The people who put down the laminate
said they wouldn't guarantee it though but two years on and all seems fine
but of course we can't see what's lurking underneath. But the laminate is
so cheap it hardly matters.
