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