water underfloor heating with no screed

As long as it is Solid then an S1 adhesive will suffice.. but always check suitability with manufacture of adhesive.

hi
i always use weber spf rapid when i need flexible adhesive and ardex fl grouts. hopefully the builder can supply these,i know the tile shop he uses have ardex grouts.
i'll call weber tomorrow and ask them.
the floor was solid from what i could tell although i will pop back and check it again when i get 5 mins.

Thank you everybody for the info and advice, very helpful and i appreciate it

if its the poly plumb system then your fine. but let the heating engineer fit the system fitted a 30mtr kit in a conserver try ended up using 4 sheets of kingspan and 100kg of self leveler also system runs at over c alot hotter than most warm water heating systems double the amount of baggie needs

That looks like it. thats great thank you very much.
i'll read it all later.
Have you tiled onto it yourself?? the builder is supplying adhesive and grout. i'll state flexible products in estimate.

No not I - I hate the system cos I sell screeds. I don't hate it because it is a poor system....it is probably very good....I just hate it on principal 🙂
