Laminate Flooring Problems


Hey guys, I have a job laying laminate flooring in a 200 sq ft open concept space. I have done a few laminate jobs before but this one is giving me a good problem. We are using kaindl 12mm laminate. Ok so after installing underlayment all was well until I got to an open end that runs into a kitchen. There was a wall separating the two rooms that we removed and the floor dips down into the transition to the kitchen where the wall was. It didn't seem too bad until we finished the floor. Any step around that area creates major sagging, not minor. I fear the plank will snap! The dip is about 1/2"-3/4" over a 5' run. It's more wavy, where the existing hardwood flooring (subfloor) dips in between floor joists. I tried to shim with cardboard but that was nothing but a headache. SLCs may only worsen the problem, but it isn't a huge space that needs attention. Would laying a new subfloor for the whole living space be the best way to handle this? I'm looking for ideas
Thanks!

Re: Laminate Flooring Problems


I would cut the laminate at the doorway and put a transition piece there.

Thanks for the quick reply. The kitchen and living space are in the same room, very open so the "doorway" stretches about 9', and base cabinets separate the two rooms. I will try the transition strip, will it stop the bouncing dramatically? I guess I will see.

Here's a picture after I started removing rows to address the problem, which is to the right of the cabinets and runs to the wall, I didn't know transition strips would fix such things but it makes a lot of sense to hold down the loose ends!

Re: Laminate Flooring Problems


Why do you think SLC would worsen the problem? You can also use roofing shingles and felt.

Re: Laminate Flooring Problems


An area that small, I would just slc the whole thing and be done with it. Easy to do, solves the problem, and profitable - where's the question?

Re: Laminate Flooring Problems


How could slc cause more problems?
When you removed the wall, why didn't you level the subfloor? Now you know why it must be done, laminate & vinyl transmits exactly how flat & true subfloor is.

Dang, I sink every nail w/ball peen hammer & fill it. Check for voids & fill anything >1/8. Usually spend 2-3x prepping vs laying da flooring!
Finished product only as good as subfloor...

Re: Laminate Flooring Problems


The subfloor has to be level or else the laminate will crack and chip. Glue some shims/masonite into the dip and bring the floor Level.

I use Hennery's levelset, it will self level and feather to .005

I had to feather this back 5' into the kitchen, floor had a swoop (old joists) to the new addition.

Since the floor is floating and you can anchor the transition it will hold the floor down. Obviously it should be leveled up and done right but if their putting some cheap laminate down that tells me they don't want to spend any money on the floor so just put that junk down and get out of ther or let someone else do it.

Re: Laminate Flooring Problems


Hey guys, I thought that a leveling compound might make the sag worse, adding additional weight to the problem that seemed to sag in between floor joists. Wasn't the case, and I used that exact product and the floor turned out really nice. Thanks for the advice!
