I have laid Quick Step Livyn LVT flooring in a lounge measuring approx 5m x 5m. It was laid on Quick Step brand underlay so it is floating type flooring. The floor was a new flowscreed that was left to dry for six months. In the middle of the floor there are now some quite large areas where the flooring has lifted a couple of mm. There is still a couple of mm clearance all around to the edges of the walls. A kitchen alongside is a similar area and is OK. Can anyone advise what has gone wrong ?
Do you have any sunlight directly on the floor or temperature change in the room? Any large items of furniture placed on top of the floor Sent from my iPhone using Tapatalk
There is sunlight in the room but the flooring closest to windows is OK and this lifted flooring is in the centre. The room has UFH but so does the kitchen where it is still flat. I can seen o option but to pull it all up and try relaying it.
No particularly large furniture. The flowscreed had a good flat surface so there was no prep. done before putting down the underlay and flooring.
I had a customer referred to me by quickstep a while ago with the same problem ,when they put the ufh on,you could see the floor rising in one spot within about 10 minutes, firstly, it rose in that spot because it was the weakest point in the room (it's usually in line with a doorway or where there is no furniture Does the kitchen join the lounge?if so, is there a washing machine or large fridge on top? Ufh does cause expansion and if something like a particularly heavy item of furniture causes resistance,the floor can lift at it's weakest point, which is usually in line with a doorway or other areas where there is nothing on top to stop it. Do you have felt pads on the bottom of your furniture?
The kitchen does jpin but is a long way from the lounge and the flooring does not go underneath the units. The lifting is right in the centre of the lounge and I first noticed the lifting whenthere was no furniture in the lounge. We now have a rug on it so it is not so noticeable. It will be a big job to remove it and re-lay it and I am concerned that the same planks have now taken a set from the lifting so would not lie flat if refitted. I am wondering if putting heavy weights ( boxes of laminate flooring) on the lifted areas would help flatten it out.
It's worth a try, double check the expansion gaps, i mean every inch, especially doorways where people tend to fit tighter to look better, it only needs to be touching in one tiny spot to make the rest of the gaps redundant
Yes it is worth looking again at gaps, I cut the bottoms off the door liners to slide it underneath so I will check that area closely.
We use Quickstep Sun heat underly with any Livyn installation that's got any sign of direct sunlight after a few problems using the standard with the floor bubbling.
