Preparation issues

Uzin do one mate

 

Its frustrating on our side of the fence as well mate, as builders normally think they know it all and get the hump when told otherwise
Likewise floorlayers who also think they know it all
The next firm should have all the gear rqd for removal of latience
diamond grinder/extractor
and hopefully some previous experience etc
good luck

 

What are your floorlayers saying about all of this?

 

No explanation for the already debonded bits. No specific response to any of the product choice issues other than that I obviously have no faith in their work and they have used the procedure numerous times with absolute perfect results.

Choice of letting them carry on and trust it will result in a perfect floor, or will remove everything.

 

they should be able to understand whats happened and explain it as such
If they don't understand (which looks like the case) then contact manufacturer or seek new company.

However, that being said, if they put their hands up saying its caught them off guard (as we've all encountered CS the first time nightmare)
and explain they will dive in and get it specced properly and do it the right way then id say give them the chance.
In a nut shell, my advice is this:

Call UZIN, get the local rep to come round and so a site inspection, arrange for the floorlayers to be there alongside
Not to point fingers, but to educate and hopefully learn something
UZIN will spec the job, I'd hazard a guess at:
mechanically remove latience
PE404 (if moisture above 75%RH)
PE360 (if 404 rqd then PE280)
NC110
Both party's will win then

 

How can they expect you to have faith when it's failed before yours and their own eyes. They are trying to dog themselves out of a hole but they've already sunk.

Fact is IF they had done their homework before any screed touched the deck then none of this would have occurred and for them to expect you to let them carry on and 'chance it' takes the piss.
All they want to do is finish the job so they can get paid then do one. Guarantee you once they are out of the door and paid then it goes pop they'll ignore you.

How did you come by these amateurs?

I'm assuming you are not there all day which gives them plenty of chance to cut more corners and smash out the blown parts and patch with the feather...They are ignoring the bottom line fact here that regardless of all needs to come up. Tell them to jog on and get the pro's in.

Have you been on the floor yourself and tapped it in random places checking how many hollow patches you got?

Pfffft about have faith in them embarrassing...

 

Better now than after all that is in, not say it's good in the first place...

 

Although offering to remove it, they're not 'putting their hands up'. There's been no discussion of dealing it.

 

Let them remove it back to the laitance as they've messed up, then get someone in to grind it, at least you'll have the floor in the correct state to start again

 

He bought my parents house - laid Karndean the whole of his life. Commercial flooring specialist. No reason not to trust.

To be honest, this was a once in a lifetime opportunity to build our own house, how we wanted, exactly where we wanted. I had done so much planning and research before we started, and have learnt so much about every trade and part of the build. I have been on site every morning before work, and available back on site at 5 minutes notice and got involved any time there was a query or potential problem.

With a professional taking on the whole floor job, I didn't see this as a job that I needed to worry about.

Although here to see the guys in each morning, on return it wasn't practical for me to go in and inspect - day 1 primed, day 2 DPM, day 3 latex screed. They left day after day 3 not to return until stairs/kitchen/skirts in and ready for Karndean. It was only when I could get in on day 4 that i started to query.

Yes, I've been on the floor and tapped it. That's why there is patched up bits on the photos. I've been back over bits of it today and found other cracks and hollow sounding bits.

 

Jeeezzzz, what a pain. I doubt it’s dry if it’s only been down 3 month. Primer below dpm? Never known anyone to do that

I understand the trust before you gave them the job but now it's gone t**s up my point was they still expecting you to trust them. If these guys are real pro's then this would have been avoided of they had of done the necessary checks before cracking on.

Also my point was tapping the hollow bits was that yes they have patched the blown parts but if there is still the hollow sections all over the floor then why havnt they seen to them aswell instead of just patching the obvious? < this still isn't the right procedure by going round digging out and patching up with feather so my point being is they are asking you to trust them still whilst they are not rectifying the problems properly, all they are doing is covering up and the exact same thing is going to happen.

If he had held his hands up and said ok we made a big blunder here and we'll start from scratch and do it properly and started lifting the screed and grinding etc but he's not is he?

So in my opinion ditch these guys and get someone else in who knows what the hell they are doing because from what you have said your guy hasn't got a clue. They shouldn't have even thought about getting the feather out and patching up where it's blown

 

I’ve agreed for them to take it out.

The response is still “I can assure you that the floor would not have failed regardless.”

 

Can't believe they still going on like it would be ok and yes it's been done many times I bet and fitters have been lucky but yours has already gone pop so.... but main thing is they are starting from scratch and least now you can get it sorted.

Last thing you wanted was to have a nice karndean laid for it to start popping up whilst you would have been moved in and living there especially with all your units/furniture in there.

Well you can kind of relax now in a sense that it's being done properly from scratch. Defo get Uzin rep in whilst your fitters are there, no more cutting corners. It's going to cost but not as much as it would if all your karndean was down!

 

So you say different materials were used? Do you know what primer , Dpm and screed?

 

Professionalism needs to go beyond just what you do.
If you are to put anything on anything you must understand the surface that you're putting it on..
They may be really good at what they do from where they start from, ie: installing smoothing compound. But, they must also understand what the product is that they are installing it onto.
Obvious that they don't. As long as they remove what they have installed and the floor gets ground off, you'll be on the right path to completing it.

 

From bottom upwards
Ardex feather and Ardurapid 45
F Ball P131
Tremco ES300
Ultrafloor Level IT2

Patching is ES300 and Ardex feather

 

Coming up on Wednesday. Told it will take a day.

To their credit they offered taking it up, and will remove it all from site.
