What happens if you don't let flooring acclimatise before laying it?

[noseynoonoo]

We're having a long running debacle with our kitchen floor. Today just half of it was layed - some spurious excuse about what they had not being right so the rest if being collected from the distributor tonight and will be laid tomorrow.

On the packaging it says that it should be left in the room it will be laid in for 24 hours prior to laying which clearly isn't goin to happen. I'm wondering how much could go wrong in the longer term. Presumably it will be stored in a cold van over night.

Oh, and this is the flooring - similar to Karndean and Amtico type flooring.

I doubt much will happen to it tonight as the temp isn't going to drop too low (well where I am so you might want to check), but they tell you to 'rest' flooring for 24 hours so it can aclimitise to the room an do any stretching or contracting that your room temp dictates.

So theorectically if it is cold when it is laid then it might slacken after it is laid and warmed up if that makes sense.

It goes like a banana after you lay it and looks badly fitted.When you walk on it -it bounces!.Can you tell i've done this with engineered wood flooring.Put in last year after being stored in the -20* cold snap.Acclimatised for a week but it was not enough[was told to do it for 2 weeks].

If it's wood, a lot can wrong bitter experience. Not sure about Kardean type stuff, can't imagine it's as temperamental as wood?

I made the opposite mistake - and left it 'acclimatising' for about 2 months - it was then too warped and wonked for the joints to clip together - wasted £200 worth of flooring - ah well!

It seems that we're going to be OK. When the fitters finally arrive today, it will be rip out the half floor that they laid yesterday and we're starting from scatch. Oh and this in their 16th visit (I said there had been a debacle). If you can hear a wailing that's me and some how I need to be civil when they turn up.

And then they ballsed up and caused more damage - forward 1 step, back about 6 steps.
