This was probably beated to death hear already, but I still
cannot collect all the pieces of this, so I thought I might
ask. If you'd be so kind to share your knowledge...
So, we have this house, which is on a slab. The floor is
Berber carpet all over (except the kitchen), and I believe
it is on plywood put onto the slab (not sure if there's any
vapor barrier under the plywood).
What we'd like to do is to put some laminate in the dining
room and in the hall, so that the carpet doesn't get stained
from food and dirt (kids!) My wife really likes the idea and
pushes me forward, but I'm a little bit reluctant -- don't
want to screw up. I'd like to DIY (or DIM).
So, here're my questions. From what I gathered, I need to put
some vapor barrier on the concrete. OK so far, but what about
the plywood which is already there? Should I remove it, or
could I put it under the laminate flooring? What are the
potential dangers of having that plywood there? I'd like to
keep it -- it will add some insulation, it will make the
floor more even (I'm not sure about flatness of the slab
underneeth). Is there going to be a problem? Would it invalidate
warranty? Also, the special foam underlayment -- do I put it
over or under the plywood?
Second, I'm looking at different laminate options, and they
seem to differ in thickness and warranties. Is the cheaper
stuff (like the one in Costco -- for some $1.49/sq.foot)
really a crap? How much difference does it make to use the
more expansive quality stuff? This is not going to be commercial
usage, just to be able to wet-moap it occasionally.
Also, I'm a bit concerned that laminate floor on a slab
will feel cold. Is this going to be a factor?
