Engineered Flooring Problem

the big 12 inch

The fact that it was made in China should tell you it is garbage...nuff said!!

the big 12 inch

Its been my experience(28 yrs)that when a big job starts out with the problems that you are having it sets the tone for how this thing will play out...I would send out letters to all people concerned stating that you feel that this product is inferior for the application and that it will not give the desired or accepted results regardless of who will be liable for the end result...When all is said and done and these floors have to be ripped out and replaced,the designer,supplier,manufacturer,GC,will all blame it on YOU...BEEN THERE-DONE THAT!!Personally I don't think any urethane glue will hold this floor down.As I stated in my earlier post,the chinese are good for fireworks and chop-suey but there hardwood floors do not meet any wood flooring quality standards that I am aware of...Good luck brother!!

I've had to use boards bowed more than that. It is fun getting it together, but not impossible.

The random stagger, will bring those boards back flat with the assembly. A premium urethane wet set adhesive will hold it down. You will always need weights and blue masking tape, when doing any gluedown. It is the nature of the beast, with these multi species engineered boards. They do that because of the different shrink & swell of the different species used in construction.

Your on the money floor guy, this is what we are doing.

I got my change order today from the GC for 65k for the extra work to glue & weigh the floor down.

I will post more pics as the job goes on,

Weights, weights and more weights to fix any bowing. Oh yeah, Made in China? Serves you right...

Cdat

Did I mention weights?

Holy nightmare.

Pavers are a good idea, ask my clumsy helper why we dont use buckets of water anymore

jamestrd

Thats unbelieveable...

I never saw anything like that..

Why not just spread Bostiks Best, let tack, then roll the floor in...

that install looks like way too much trouble, more than it was worth..

was the slab or materials shot?m looks like Bellawood...nuff said

short of some minor random hollow spots needing some weight, never came across anything like that

Mike Costello

I have, rather than walk away ya make due.

Its also a way to conform it to a less than within tolerance floor

The pictures above shows solid 3/4" flooring, not engineered.I have seen it GC's page before. The floor shown there Bellawood from LL more likely brazilian made..
Most Solid boards can be installed over slab with proper adhesive(shorts for domestics-standard for some exotics-if the boards are straight)
Usually moisture cure polyurethane adhesive like Bostik's Best will hold pretty well if the slab is dead flat.I roll with 150 lbs rollers within a couple of hours of installation just to be sure.
Looking forward to see more pics. 65K ...not bad eh?

We dont use pipe clamps for soild timber driect stick we fix lengths of timber down and wedge of that,

That is hilarious!!! Hope you bid that one right. Looks like it is already cupping. Nice moisture barrier, there.

Not my work. I do inlays and borders cut into other peoples work usually. This is a job done in Florida by someone else. I just used it to relate to the thread. The only way you'll see my work is if you visit the homes or businesses that I've worked with due to my anal retentive mindset on my skills.

Maybe we should put out a request to our experts in the concrete trades to explain why they can't pour a flat level sub floor...just askin

Job is underway now, very slowly.

we have had added problems with GCs leveling contractor doing a rubbish job so we are having to grind and re top.

These pics, show the 10mm (3/8) rubber acoustic membrane which is trowel glued with polyurthane to the concerete slab.

these pics show the boards being laid we are doing one row at a time, we are not needing to much weight to hold the boards down just a few buckets of glue.

the finshed floors are covered with thin foam underlay then MDF sheets to stop the other trades from damaging the finshed floors.

Isnt it summer there now? Im sure you could get a thousand or so of us over here to come help!

Nice work!

It seems to be going very well and it all looks good. I have one word of caution for you.... and that is to keep a check that the wood does not start to cup because it is now sandwiched and you have the potential of causing a green house effect by keeping it covered in that manner. I am not criticizing anything... just not sure you are aware this has happened before....
