Newly laid floor flexes on 3 floors and in all rooms

[TRJBerg]

This problem cannot be ordinary or expected behavior. I mean, if this were common, it would be widely reported in the media.

The living room is separate and doesn't connect to the kitchen and the hall in one sweep. There is an expansion joint in the portal from the living room out into the hall.

But maybe it's still too large an area to lay in one sweep. Unfortunately, it also bounces just as badly in the living room and hall as it does in the kitchen.

We have about 9m in one sweep with Kährs 14mm 3-strip matt lacquered and it has been fine for 5 years. But I recall that about 10m is the limit.

Is there plastic under the floor?

Is there plastic under the floor?

It's khars foam for underfloor heating under the floors

No diffusion plastic then, or is it a combo?

Yep, it's a combo.

The foam is laminated. 👍
Used that last time I laid flooring.

Yes, I am honestly considering that path,

Sure, the floor is in the cheaper segment, but I read up and it was a test winner in several comparisons regarding wear, easy to lay, etc.

I have been renovating for 2.5 months over a 5-month period. And I'm starting to get really exhausted.

I had booked a construction cleaning for Wed next week as I expected all the craftsmen to be finished this week.

Now I've run out of steam, one might say

A floor from Byggmax at this level of floor renovation?

I don't understand, why take a chance with a Barlinek floor when laying new flooring of this size?

I have personally laid an oak floor from Kährs in the house, about 140 sqm, very high quality and also easy to install, bought from K-Rauta for about 260 SEK/sqm. I also used Tuplex underlay foam and was very pleased with the quality.

I don't understand, why risk it with a Barlinek floor when installing a new floor of this size?

I installed an oak floor from Kährs in the house myself, about 140 sqm, very high quality and also easy to install, bought from K-Rauta for about 260 SEK/sqm. I also used Tuplex underlay foam and was very satisfied with the quality.

Yes, I saw those cheap Kährs floors where you can buy 3-strip oak parquet for 280 SEK/m2 at Beijer, but I liked the look of this floor and it was significantly more expensive.

I sincerely hope it's the floor that's the problem and not the workmanship. It would feel so much better than the carpenters having made a mistake.

But as I said, in 1 week we'll get the verdict, and then it's just a matter of falling in line for the parties involved 😁

Kärsh has absolutely quality flooring, but to believe that all flooring from kärsh is of quality, then you are barking up the wrong tree.

They have had to adapt like all other manufacturers to the budget market to survive.

But, as mentioned, in 1 week the verdict will come, and then it's just a matter of falling in line for the parties involved 😁

Excited to hear the "result"
I'm guessing poor subfloor overall in the house combined with really high humidity and budget flooring.

The old floor joists looked like they were crying for help. You can't put something together that crooked even if you try.

You can clearly see the bounce in the video and there isn't enough force to affect the underlying bjäkar, but it may indeed be a combination of several factors, even likely.

Exciting to hear the "result"
I guess it’s due to a lousy overall framework in the house combined with really high humidity and budget flooring.

The old floor beams looked like they were screaming for help. You couldn't nail something together that crooked even if you tried.

Yes, that the old framework is lousy is no doubt, probably why it was re-aligned and new studs installed?

I have measured the humidity since the problem was discovered, and over the last few weeks, it has been a maximum of 55% down to a minimum of 35%.

Sure, there are much more expensive floors but also much cheaper ones. When 250 m2 of flooring needs to be purchased, there are huge differences in the final total if you buy flooring for 400 SEK/m2 or 1200 SEK/m2, such a big difference that you could re-lay the floor one extra time and still afford to hire craftsmen to install it again and have money left over for a nice vacation.

And is it the right sheet metal and floor heating system for the sawdust?

 

[Peter Petterson]

And it's the right sheet and underfloor heating system for the chipboard?

Yes, both the sheet, chipboard, and underfloor heating are delivered by one and the same supplier
