Laying LVT on an uneven floor

Is LVT with integrated underlay any good for uneven floors?

If it's floorboards then a thicker ply is required; 9mm or thicker if it's really bad.

I'd it's concrete then it will need a smoothing compound first.

And if that's the case, you'd be far better off having a gluedown LVT than click LVT which is just rubbish."

"Not really any Lvt required a level floor to lay on or the joints may open up"

"You can lay it on an uneven floor upto a couple of mm but I wouldn't personally as it can effect boards in time .For the money you pay its worth self levelling it first ."

"No, you have to get the floor to SR1. To more then a 3mm gap under a 2m straight edge."

"No you will have to flatten your subfloor first otherwise it will damage the LVT"

"Make sure the subfloor is even before laying LVT flooring."

"Not really, LVT should always be laid on a level substrate"

"In short the answer is no. If it's a click version of the subfloor is uneven it will put stress on the joints and the will open and if it's a dryback with xtra underlay you will see every contour or ridge etc. In general for and click or dryback lvt the floors have to be smooth and clear of any contamination."
