Here is a product made for moisture problems. As Joseph said, you must
deal with the moisture transmission level for success.

product was recently installed on a problem floor area, the new VCT has
been laid, no problems month #1, only time will tell.

My personal experience with self stick is very poor. I have talked with
many commercial floor installers - none I know will install self stick
without using their own glue.

The industry requires and suggests calcium chloride tests for vapor
transmission before flooring installations. This is a wide spread
problem brought on by tighter buildings, increased fresh air HVAC
requirements that can cause short cycling, faster building schedules,
and vapor barrier problems.

A dehumidifier may help, but cannot cure if the vapor transmission rate
of the floor is over 6 lbs./1000/day

We found some decent looking wood pattern Peel and Stick Tile (Vinyl,
I
think) which
we thought would work over the cement floor in the basement. After a
little
while
after applying (days or weeks) they started to peel and warp upwards.

It was very humid in the basement, could that have helped cause this
problem? We
put in a dehumidifier and I think I'll get one of those aquarium pumps
referred to in
other posts to automatically empty it, because I don't think my son
bothers
to empty
it, and I don't get down there too often.

It seems to alleviate the problem somewhat, but I don't get down there
too
often and
don't look too closely. Should I have put down a plywood layer over
the
cement first,
then the tiles? I know this is better, but is it absolutely
necessary?

I've been told the glue on the self-adhesives is fine. Any comments
on
that?
