Here's the situation - I laid 32 sq. ft. of 12" x 12" parquet flooring
tiles
this weekend. Mfgr's instruction stated it needed to be glued (I used
the
appropriate glue and trowel). It also stated to leave a 1/4" gap
around the
walls which I did for expansion. Don't understand how it would expand
if it
was glued down - but I did it anyway. I laid this same floor in my
master
bedroom 4 weeks ago and no problems. It is tongue and grooved on all
sides.
I woke up this morning and have a ridge down the middle of the floor
which
buckled and raised almost an inch. I'm thinnking the wood expanded
alright
. . . now how to deal with it. My first thought since I can stand on
it and
it lays down okay was to make an attempt to inject glue into the
bottom
somehow and weight it down. However, if it really is expansion, it
will
happen again somewhere else. What do you think? Take my circular saw
set
at a very low depth and make a relief and then glue back down? Need
some
suggestions from the pros.

Thanks

First thing comes to mind, the flooring wasn't acclimated to the same
environment 72-96 hrs. b/4, or the time period recommended by the
manufacturer. Sometimes people keep the material in a different room,
which is not acceptable. Or they stand material in the corner. It must
acclimate in the room the flooring is to be laid, and laid flat prior to
installing.

Is this over a wood substrate?
