Mapeker for fixing down Warmup insulation boards?

[Qwerty]

I have a few bags of Mapeker to use up and was wondering if it would be suitable to use for fixing down warmup insulation boards, and then again on top of the warmup ufh (loose wire) for fixing down ceramic floor tiles.

Also, what size trowel is best for the boards???

Substrate is concrete screed by the way

No you need a SPF for this.

Im now confused..........replies from 2 very experienced tilers....... yay or nay?

I also have 6 bags of keraflex maxi, but would like to use the mapeker if possible.

Nothing in my Mapei books about it being suitable ??

Mapeker is a C2 adhesive and fine for what you need....and also suitable for ply overlay of 15mm and above..

i think Mapei need to keep up with there brochures :mad2:

yes Dave is right (as usual) ( although i still wouldnt use it myself)
It seems they have done recent tests and have found that and i quote "Basically we've been under selling the product!!"
they also state that the UFH should " be encapsulated in a SLC"
