I was shopping flooring yesterday and the largest flooring retailer in
our area will not glue a wood (of any kind - engineered, veneer, etc.)
floor on a house more than 15 years old. The houses around here are
built on concrete slabs, so the subfloor on the bottom floor is
concrete and the ground in Houston may stay wet for long periods. The
floor retailer says the moisture barrier builders place when the house
is built has disintegrated by 15 years, so moisture wicks up through
the floor and will destroy the glue bond.
Seems like the glue itself would provide a moisture barrier, but what
do I know? Anybody have any insight on this?
All of the engineered floors I have worked with, "floated" I.E. not attached
to ground level concrete slabs. Besides your going to want to put a pad
underneath the flooring to give it that cushy feeling.
THere are lots of floors for slabs. Some only for above grade. Follow the
manufactuer's installation instructions if you want the warranty to apply.
The ones I see float and you put a special pad below them.
A. Was this explaination a prelude to any kind of additional charge? Hmm?
B. We put down a hardwood floor on a 40-year-old concrete slab a few years
ago (in Houston). Worked swell.
Now think about it: the wooden tiles are inter-locked. So what if the glue
goes bad? The floor is maybe going to levitate? Anyway, the floor tiles
move - as much as 1/2" - as they expand and contract due to temperature and
moisture so it's not as if you want the wood epoxied to the concrete anyway.
I don't think so. They do it on houses younger than 15 years, and all
they did was steer me to a snap together floating floor, which didn't
seem much different in price. If anything it may have been a little
