Weber set plus suitable with underfloor heating or not?

[Unused Account 1]

Some off the addy says suitable for ufh ,but doesnt say flexible bit weird

 

[Andy Rhodes]

It stating on the technical datasheet that weber standard set is suitable for heated floors & says as follows.
The heat must be turned off & should been turned on gradually at least 5 days after tiling.If the substrate is timber it must be overboarded * weber AD250 used in the mix hope this helps

the issue weber are having is they have removed 'suitabe for ufh' from the bag.

 

[Andy Rhodes]

Isn't that why we refer to there technical data sheet though.its only a issue if its not on a data shers

 

[J Sid]

your right Andy, my problem is it was clearly stated on the front of the bag and now its not. My first point of reference is the info on the bag.
if I go into a shop to buy some floor tile adhesive for, say, porcelain on wet ufh and BAL, Ultra, Ardex and Mapei all clearly state 'suitable for porcelain and ufh' on the bag I will pick one of those. I will not search the web for the spec sheets to find out what each one does, hence I will not use Weber set plus eco.

 

[Andy Rhodes]

I see your point sorry, I use Weber on almost all my jobs so because I've used it on uhf jobs just took it for granted it was incoparated within that data on the back of the bag still

 

[J Sid]

I have used it for 10 years or so, and has always said on the bag what it can be used for. They changed the bags and removed the specs, so I changed adhesive manufacturer.

I love the stuff & It's the right price , so as a point I will download their data sheet just to cover myself should the worse happen but thanks for the heads up

@Joe Parker may want to add to his products suitability!

I'd check that the data sheet online is up to date!

 

[Andy Rhodes]

I would like to say yes, but who knows could have been an old PDF version, so I'll hold my hands up & apologize if it is now

Apologies that there seems to have been some confusion regarding this, hopefully I can clarify things.


Previously, the packaging for weberset plus stated that it was suitable for use with underfloor heating. On the back of the bag and on the datasheet it clarified that this was only the case if mixed with weber AD250. This essentially gave a C2T adhesive S2 properties.


We wanted to make things a bit clearer as we felt that it may not have been clear that this product was only suitable over UFH when using an additive. To do this, we decided to remove mention of underfloor heating from the bag.


If you wished to, using weberset plus, mixed with weber AD250, over underfloor heating is still perfectly possible.


As per BS 3585-3 we would always recommend an adhesive with a minimum C1S1 classification is used for underfloor heating. If you were looking for a solution that was not “bag and bottle” we would suggest considering an adhesive such as weberset rapid SPF, weberset SPF or weberset pro lite rapid.


In terms of datasheets, our website contains the latest version, which can be found in the Download Centre or the Product Documentation section for each product.


Apologies again for the confusion and we hope that this clears things up.


Please don’t hesitate to get in contact if you would like to discuss this further or have any other concerns.

I have to say I find that misleading and imagine it was removed down to a claim against weber. Glad I never used it with ufh

 

[J Sid]

yes Harry, I have to agree.
I've used it for years and never seen anywhere it needs an addmix for ufh.
the staff at my local CTD where never aware of this and have not given this info out.
and just checking the website of weber it isn't clear still


I have not had any failures (so far) and will never be using weber again.
as you say Harry, maybe had some problems, we will never know. But I find there behaviour to be under hand to say the least.

@Joe Parker you have to remember, most of us are simple tiles and need clear and concise information in big letters on the front of products we may buy.
