I'm not familiar with the product. Does it have a fibre glass stabilisation layer built in?
The vinyl planks can expand in the heat caused by direct sunlight and, depending on the floor temp, product temp and changes in direct sunlight during install, will shrink (sometimes to slightly smaller).
Does the cupping come and go with changes in the weather?
I try and block out direct sun when installing and also try to install the planks at the same temp as the subfloor or even a couple of degrees cooler.
Did some more looking. The kitchen window has a tree nearby, so there is no direct sunlight coming in.
Not sure about the fiberglass, cant find a composition list.
So far it doesn't seem to be seasonal.
Got the instructions for both the flooring and the underlayment, all instructions were followed to the letter, so it's not instillation error as far as that goes.
What I may do is take it up, and replace the dishing boards, and see if it happens again. I'm really at a loss here.
I was considering LL's Tranquility 4mm Maple click product and am looking forward to a further report on your cupping/dishing mystery. Hard to imagine how a vinyl product could react this way...
That is, unless it's not solid vinyl but actually laminated from different materials. Let's see, if it's dishing, then the underside layer would be expanding at a greater rate than the top surface (or, vice versa, the top is shrinking.) Does this sound right? I wonder if there's any chance the underlayment is exerting upward pressure somehow?
Hi, I'm a do-it-yourselfer who about 900 square feet of Tranquility Rose 4mm click in my home over the past couple of months. My first comment is I would not recommend this product to anyone, it is ridiculously easy to scratch and (of course) the warranty doesn't cover scratches. Touch it wrong, sweep too hard and you have permanent scratches. I sent a few boards back to Lumber Liquidators at their request, they tested it and said it is within their acceptable wear standards, so ... that's that. 50 year warranty, yes ... but if it doesn't cover scratching and wear ... ?
My second comment is about cupping. The first area I laid down is laying nice and flat. The area I did a couple of weeks ago has several cupped vinyl planks (up in the middle, down at the edges). Some are full lengths, some are partial. Some are where they'd be hit by light from a window, some aren't ... but as someone else said, what kind of house doesn't have windows? The moisture level on this area of concrete slab is the same as the rest of the house. Yes, it was acclimated to the room for several weeks before installing. Today I pulled up the cupped ones and started to put down some from the box that don't appear to be cupped, but I'm not convinced they were cupped when I put them down. I started searching and found this topic, just wondering if there is any update on the problem?
PHOTOS: The cupping is clearly seen in the first photo. The second one shows some of the scratches I'm talking about. No abuse, just daily living. It's under a garbage can with a plastic bottom ... the same garbage can sat on our hardwood floor for seven years in the previous house and didn't scratch it at all.

Some floors scratch easier than others. It's not only a difference in material, but also in finishes and the kind of dirt that can find its way under that trash can that gets moved around and ground down whenever you put your foot on the lid lever. You said your old floor was hardwood, but this one is vinyl. The reality that most people experience is that all floors scratch under the right (or wrong) circumstances. No company will warranty against scratches.

That is called crowning, not cupping. Did you glue the floor down with the proper adhesive and use the proper methods described in the instructions? It could be several different problems, from wrong adhesive, wrong trowel, too much open time, not rolling and on and on.
Thanks for the replies ... yes, it's a floating click-together floor, and yes, crowning is a more accurate term than cupping for what my floor is doing.
My comments about the scratching were meant to comment on my personal experience only, in case someone else is considering it. I realize that all floors can scratch, but this floor, as I said, is "ridiculously easy" to scratch, and I stand by that statement. I'm 51 years old and over the past 30 years have installed linoleum, ceramic tile, pergo, hardwood, and now this in the various homes I've owned over the years. This is the only floor I've ever had that I have had to be concerned about new scratches every single day.
I posted only one photo to illustrate my point, but every room is full of scratches from things like a cardboard box being slid, dog's toenails just from walking on the floor, etc. Don't believe me? Buy some and install it in a room in your house (that you actually use), come back in 30 days and tell me I'm wrong about this stuff. I realize that it's all subjective, and maybe some people love it, but I have never been so sorry that I bought a product in my life.
All of that said, I'm stuck with this floor for the next few years until I can afford to replace it, but I came here to see if I could find out why it's cupping (oops, sorry ... crowning), and if there's anything that could be done about it. Any thoughts would be welcome. Like the previous poster, I'm in the middle of replacing the rounded planks to see if the new ones do the same thing or not.
Yes, there is a 1/4" gap around the perimeter. The step was tiled after the vinyl plank floor went down ... it was already crowning before I tiled the step. Also, some of the rounded planks are to the left, where there is no tile. It's a very strange phenomenon.
Wow I like your term phenomenon, they used that term for "Pile Reversal" back in the day for carpet when it would inexplicably change which way it would lay , been a while since I followed up on that.
I'm not familiar with your exact product, there's no lumber liquidators close by, but if it makes you feel better, I've seen many vinyl plank problems other than your brand with same problem and others glued down that shrink leaving gaps in the floor around every plank.
Understand that I have nothing against Lumber Liquidators, I think they are a good company and most of their products are excellent ... the 3/4" Brazilian Cherry I bought from them 7 years ago was awesome and looked as good when I sold the house as the day I put it down. I am just very disappointed with this particular product, and with the touted "50 year warranty" which turned out to be (in my opinion) pretty much worthless.
I wonder if improper storage at the store could have been a factor? In other words, I bought all the flooring in March for the rest of the house, but ran out and didn't worry about it because I wasn't quite ready to finish the floor. I went back when I was ready (after exploring the option that the warranty would replace the floor with something better) ... and bought two more boxes to finish up. The "rounded planks" all came from one of those two boxes ... the other one I just opened today to replace the rounded ones.
I can't see what could have been different about the boxes (although one was manufactured in February 13 and one in March 13). The "rounded" ones all came from the box made in February. But then again, I can't see how they could be stored improperly either ... at LL every time I've seen their product it's been stored flat on pallets. So I'm stumped.
Fifty years didn't seem outlandish to you? When I see warranties that long, even half that long, I have to wonder if it's an indication of their quality or just some marketing genius' conviction that people are gullible enough to believe the product must be that good.
You could press a claim for crowned product. That could be manufacturing or it could be installation related. But when you press for replacement because of scratches, you will never win. Don't even try. No flooring product is scratch proof.
And you should poll flooring professionals on their confidence in LL as a company and their products as high quality. I'm happy that you had a good experience 7 years ago with them. But when a company has multiple lawsuits pending, some federal, I would be cautious. What is their record on warranty claims? Where do the vast majority of their products come from and is there any quality control there?
