Weber set plus suitable with underfloor heating or not? Page: 8

[Andy Allen]

And just to add...
On the old bags on the front it said suitable for UFH.....and no mention of using an admixture...

@Andy Rhodes
Have you actually read this thread ??
It's quite simple...
One minute Weber say it's suitable for UFH.
And now they say not....
However this is after me and a fair few other excellent tilers have already used it on UFH...

 

[Andy Rhodes]

In answer to your question?
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...? Yes I read the thread
In answer to Paul's before your reply I've seen Julian posted on
page 2.... it says to use AD250, only on timber floors, no mention of UFH,which Julian got off the technical data sheet 11-025 Weberset plus that document has 2 pages ,on the second page under the heading underfloor heating/undertile warming on a solid substrates
it quotes ,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 over boarded & Weber AD250 used in the mix.
I was always taught that if you are unsure about a product read the technical data sheets provided by the manufacturer.

on the second page under the heading underfloor heating/undertile warming on a solid substrates it quotes ,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 over boarded & Weber AD250 used in the mix.

Show me where it says "if it is a heated screed or an electric system over a sand/cement substrate, you must add AD250"..........

Its now a blanket instruction on underfloor heating, regardless of substrate, that an additive is used!!! So yeah, pretty misleading in my book.

How much is a bag and bottle of that any way . Surely there are cheaper reliable single parts that will do that job .

As i was asked a couple of hours ago,
Have you actually read this thread ?
In my last quoted,
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 over boarded & Weber AD250 used in the mix.
It only mentions adding AD250 if the substrate is timber,
I didn't say it should be added AD250 to the adhesive if your going on sand & cement screed or have I said this,yes i have mentioned that I have put mixed it with set plus earlier in this thread but that's because I made a conscious decision to do so as I thought it was the right call, so agree or disagree with what I've said.
In question to how much I pay for Weber & the AD250 £20.50 roughly + vodka & tonic

 

[Andy Allen]

You any relation to lugi. ..?

 

[Andy Rhodes]

No, you didn't, but that is now Webers Stance on it, hence why they are going to all the trouble to amend the packaging. Underfloor Heating = AD250. End of! And it's causing a lot of very squeaky bottoms of tilers who have used this product in the past, on underfloor heating, without an additive.

you posted the spec & circled suitable for heated floors, so were's it mis-leading

Apologies if I have and please point it out if I've missed something, but the way you were coming across is that you think the way it was originally written, was not misleading? When you see "Suitable for underfloor heating" as a USP, and only a flitting instruction on the back of the bag to use an additive over heated timber substrates, what does that say to you? to me, at the very least, it screams "On anything, not timber, Weberset Plus can be used on underfloor heating, straight from the bag". If I was to pick up a bag, why would I be in any doubt or have to look at a datasheet with such a black and white statement?

 

[Andy Rhodes]

Okay I see that point but not wishing to put the cat amongst the pigeons they could turn round and say & god forbid they better not after the coating I've just took ,why didndi you fit anti-facture mat to stop this possibly happening

@Andy Rhodes
formula of product hasn't changed


anti crack mat or not, its still a heated screed
