    Hi - recently had karndean art tiles laid in new extension and they are coming unstuck. Tiles are laid over a 10mm latex screed with underfloor heating which has been attached to thermal boards. When peeling back the tiles there is moisture on the underside of the tiles. Is it likely the screed hasnt properly dried before the tiles were laid? Any advice very welcome.

    Sounds like it yes.
    Who laid the flooring ?
    How old was the slab? Is it sand and cement ?

    Hi
    I am in urgent need of advice. I ordered lvt flooring from a local flooring shop and he has just turned up with what appears to be a different product? I ordered Distinctive Cezane flooring from the Autograph range and he has arrived with MFlor Woburn Wood Bedgebury Oak. He is saying that they are the same product as Distinctive is the uk supplier of MFlor but according to each product's websites they are different spec? Autograph spec is 0.55mm wear layer and has a warranty for domestic use of 25yrs but MFlor spec is 0.3mm wear layer and has a warranty for domestic use of 10 yrs.
    I decided to go with Distinctive originally as I am laying this in my 'forever house' and need the flooring to last as long as I do!
    Anyone got any pearls of wisdom out there?

    I’ve had the same issue from customers with Karndean not saying Karndean on the box
    It just doesn’t because it was sold under a different name in some European countries

    Mflor is sold under the Distinctive brand in the UK

    A couple of days. However the work was done over a very cold week in December. I have since read that tiles shouldnt be fitted below 17C - is this correct?

    Not completely

    Tiles should be acclimated to room temperature and the temperature maintained 24 hours before during and 24 hours after installation
    All UFH should you be switched off 48 hours before installation and then 48 hours after installation should be turn up gradually by a couple of degrees a day but not exceed 27 degrees

    What latex was used? It probably never dried out if you didn’t have any heating on. Defo not in a few day if it’s that deep. When the heatings turned on it forced out the trapped moisture in the latex. I had the same on a job. Luckily it had been laid on moisture tolerant levelling compound and ps adhesive so it was quite easy to fix.
