Thanks guys. Yes a massive headache for us as homeowners, we had already moved out for 8 months, now all furniture in place and decorating done (thankfully not skirting yet) so not sure where we will go but cross that bridge when we come to it. Just need floorer to admit fault first. Appreciate your input and will let you know how I get on!
Just so your aware, there are systems available for damp anhydrite screeds with underfloor heating. So, if its still damp, this can be dealt with.
If you have underfloor heating it could be used to help dry the screed before you get someone (a professional) to undertake the relaying of the floor.
Complete prep failer It's most likely dry if you forced dried it Anhydrite dries very quickly Thats one of its benefits
As above really, there’s calcium sulphate screeds for calcium sulphate sub floors, grind it back and start again, plenty of systems available, case hardeners, dpm, primers, new screed etc, loads of options. Not just NA.
Hi, I've got some clearer photos now. Where the floor is blowing it is so easy just to pull a tile up. You'll see attached the latex is still on the floor tile with small pin holes appearing. I can only see one layer of anything, doesn't appear to be any layer of primer??? Thoughts from you pros??!
No primer, does look grinded but could just mean the latence is stuck to the blown screed Sent from my iPhone using Tapatalk
What do you mean by grinded? Note we did remove the laitance first time round with a rotary floor sander. Hoping you are saving it doesnt need another sand then?! As such a messy job!
I don’t think it does now but there should of been a full surface grind by the screed company y after it was done Sent from my iPhone using Tapatalk
Latience hardens the longer it’s left should be removed 4-6 days after I had a job once where the builder told me it was power floated concrete the latience hadn’t been removed at all and the latience looked grey I prepared at with copper disc and it just skimmed it because the latience was so hard making me think it was power float , I primed etc the floor blew found out after he’d got a company in then was told it was anhidrite by the contractor I told the customer I’d replace the lot sometimes mistakes happen and ya have to take it on the chin
Floor laitance in this situation was removed within the week so not a problem there. Spacey- floor blew within a few days of laying in one area before it was fixed. Had another 2 patch jobs since that and now daily there is more blowing. 2 months later!
He should replace in my opinion wrong screed used it not the fault of the customer ya payed for nice floor not a nightmare
Wrong levelling compound, should of had 2 coats of acrylic primer and a gypsum based smoothing compound. And then hope it never gets wet Sent from my iPhone using Tapatalk
