hello
sorry for the very long post but please read.
can anyone advise please
been laying laminated and real wood flooring for some years now never had any problems until now
i laid down my friends 12mm real wood flooring bought from BQ
i always read the instructions did all it said to do but nothing about the underlay so we went back to BQ
they advised us to buy this underlay i have never used this before or heard of it but it looked good !!!!
Diall 3mm Foam Self Adhesive Flooring Underlay £48 per roll
all went down OK a little tricky at times but ok
that was in feb, this year last month she had BQ staff at to her home to inspect it
and now B&Q has paid out £300 for an independent surveyor to inspect the flooring
damp test. he took readings from under the floor swabs from the floor and so on
my friend asked him if he could disclose if he had seen this problem before but would not say as B&Q is paying for the survey
now on to the floor well what a shock i had i have never seen a floor like it !!!!
its like walking on a corrugated sheet with all those ridges but bigger much bigger !!!! the whole floor has lifted
all i can say i laid the floor in Feb when the house was empty also i did state at the time they should put the heating on now and then
they had no heating on until a few weeks later ?
i left the stranded 12mm / 15mm gap all around
i have glued floors down and laid floating floors but never seen this before
this underlay is a black thick rubbery roll with polythene on it and you remove the polythene a little at a time then stick the flooring down to it seems so simple
to think that all this very warm weather we have had it should of shrunk but has expanded greatly
they don't use water they use those a micro mop with a gun on the end of it with flooring solution
they tell me when they put the heating on the floor gets worse as it gets warmer ?
just asking if anyone has had this problem
thank you Paul
PS laid on a concrete floor with marly tiles down the house is around 20 years old
