    Default Underfloor heating problems!!

    Hi All,

    Looking for your opinions on this....

    Started a job today, well tried to!

    Job details: 64 m2, tiles size- 1200x20 (wood effect) porcelain, underfloor heating (wet system - polypipe).

    Ok, I started this job today, got there to find that the plumbers that installed the heating system have done a poor job to say the least! the floor isn't flat at all.

    when quoting, the customers had told me that they want me to tile directly onto the heating system. I recommended something on top i.e. cement boards.
    They said that polypipe had said that if I don't fix directly onto the pipes then they WONT honor the guarantee! This seemed very strange to me so I thought I would investigate further.....

    The addy that porcelenosa had supplied with the tiles is Butech 1flex. I called Butech/BAL and they told me definitely dont fix directly onto the system as it will fail! - I thought this much....

    They suggested using a cement board. Exactly what I wanted to do! however, they recommend sticking and screwing this down. Norm not a prob but with the whole floor covered in pipework I really dont fancy this!!!! especially as the pipework is a bit of a mess (cant see where all pipes are!).

    We got back onto polypipe and explained the situation and they said there is another option. as follows;

    Another option for installation, as recommended by Mapei and advised by Polypipe:


    1. Vacuum entire area.
    2. Prime the Overlay boards using Mapei Eco Prime T, diluted 1:1 with water.
    3. Once dry, apply Mapei Fibreplan levelling compound, ensuring minimum thickness of 5mm above panels.
    4. Once dry the tiling can be adhered using Mapei Keraquick Grey or White.
    5. Grout tiles using Mapei Ultracolour Plus.

    they still haven't really said if they will honor the guarantee using this method though!

    Besides that, I looked into it and this method will cost a fortune! And on top of that I cant find anywhere that has this amount of fiberplan in stock!

    I need to sort this quick as I have allowed 4/5 days for this but have already wasted today and am fully booked after this week!

    Can anyone think of an alternative???

    Thanks in advance

    This system has been discussed many times. I have done 2 of these systems now and I used SLC then Ditra/Dural Ci over the top.

    Thanks, The only problem is that polypipe are saying to use fibreplan only and not sure the customer will be willing to go against this as it will invalidate the guarantee.

    Renovation screed is the same as Fiberplan but without so many Fibres. I would have a chat to Mapei Tech dept.

    If the system cannot be tiled itis presumably not fit for the purpose for whichit was supplied.

    What uarantee are polypipe offering or ot offering as the case may be.
