Weber Weber set plus suitable with underfloor heating or not? - Tile Advice

[Andy Allen]

Always said on the bags suitable for UFH, notice today it's disappeared off the bag.....
Web site, pdf, and technical advice all seem sketchy..?
Any one know if the format has been changed...?

Always remember seeing that myself. Only used it a few times and never with ufh. A C2 with bare minimum polymer imo. Cleaned off everything very easily. Not a fan

 

[Andy Allen]

I've used it on ufh with no issues...
Didn't take the risk this time, took it all back and swapped it for the trade flexible, stuck the bloody insulation boards down with it though, hope it doesn't come back to bite me ...

 

[On one]

Never noticed anything on the bags about ufh before,so just assumed it wasn't suitable and used Weber's slow set flexible or rapid set flexible adhesive.

 

[Andy Allen]

I'm sure @JulianSidney used to use it too.

@Andy Allen I used the eco grey for many years, said on the bag and the website 'suitable for ufh' but disappeared off the bag and the shop manager couldn't find out why. Moved over to ultra S1 now and don't use any weber adhesive at all. Can't be trusted if that's what they do. ( plus I can get the ultra at a good price )

Totally agree, poor show from Weber.
Even rang there technical Dept this morning, and not even they could verify if it still suitable for UFH...

I've only used Webber adhesive once that I can recall and it didn't seem all that great. Julian which ultra adhesives do you use ? Not blue bag ?

Totally agree with Julian and did the same move.

[J Sid]

yes from CTD and is very nice to use, well the white slow and rapid set S1 is, don't like the grey

Looks like sp es in a trade bag. Lovely adhesive that Julian, not tried the rapid version but I know the grey is really nasty to use
