Strange tiling problem :)

[joe-90]

Plasterboard and full tanking, beats Aquapanel and their jointing system every time.............Period

Tell that to Knauf - not me.

Who said I was talking to you..........

Do you know what full tanking entails..........

I'm not playing your game Joe - grow up.
I only recommend tanking Aquapanel when fitting small tiles - you get more moisture making it's way through with smaller tiles.
Of course, you'll finish a house, sell it and it'll be someone else's problem in a few months. Why don't you post your name on here so that we know not to buy a house from you?

I'm sure Knauf (who make Aquapanel, a World-wide company employing 18,000 people) know what they are talking about!

The Knauf Aquapanel does indeed allow moisture through the board over
time. The level of water resistance and water proofness you require for
a domestic use can be achieved just the tiling and grouting. The board
is designed to maintain its strength and performance although completely
wet, so if the tiling or grouting does fail, the board will still
maintain.

The use of a tanking or vapour control layer behind the board is only
suggested for commercial areas such as public changing rooms or swimming
pool areas. For a domestic shower this is required, although you can
incorporate it if you prefer.

Please note the smooth surface of the board is ready to receive tiling.
Should a tanking system be used to this face of the board, we would not
be able to guarantee the adhesion of the tanking system to the board or
the tiles onto the tanking system.

We hope this information is sufficient. Please do not hesitate to
contact us should you require further information.

Leaving aside the fact that Knauf state that tanking is required, which is probably no more than an embarassing typo on the part of either Knauf or joe-90, I note that Harinder Kaur doesn't warrant that tanking is not required, he just gives an opinion without presenting any reason for that opinion.

Given that the price of a tanking kit is about £30, you'd have to be stupid to think that taking the risk is either sensible or worthwhile.

[Softus]

I don't know what that is supposed to mean.

 

[gcol]

Was meant to mean that Joe has been put in his place.

 

[Softus]

Oh I see!

Do you underestimate joe's ability to think that he's right in the face of overwhelming evidence to the contrary?

 

[gcol]

Hmmm you may be right there.

At the risk of having my head bitten off, I read the following quote by Knauf as warning against tanking

we would not be able to guarantee the adhesion of the tanking system to the board or the tiles onto the tanking system.

Just wondering which is the biggest risk, the aqua panel not doing the job it's designed to do or the tiles falling off cos I tanked


I've just used Knauf aquapanel without tanking as per instruction by the plumbers' merchants I bought it off, I trusted their advice as I thought that they could easlily have gotten another sale out of me by convincing me I needed to tank ergo, selling me a tanking kit.

...So I'm secretly hoping Joe-90 is right

No offence to anyone here as I've been given great advice from the regulars throughout my bathroom project (on the home straight now!!)

It's an abdication of responsibility if you tank in front of the Aquapanel, but their 'warning' doesn't extend to the scenario of tanking behind it.

The Aquapanel will do what's desired of it if you install it right, and with the right screws. Tanking isn't compulsory, but most good professionals will tank a shower area because they know that, if not maintained, the grout will crack and let some water through.

Oh yes, those merchants know so much more than the plumbers who actually do the work.

From whom are you keeping this a secret?

Wouldn't the merchants get feedback from the plumbers and tilers re. their products?

From whom are you keeping this a secret?

Ooops did I say that out loud?

So would it be advantagious to tank the back of the aquapanel? (I have access to the back via a dummy door)

Also you mention 'maintaining' the grout, what would that entail just so I can prevent any damage occuring?

 

[joe-90]

Don't be silly folks. Knauf state that in a domestic situation that tanking is NOT necessary. If it was - there'd be no point in producing the product - may as well use plasterboard!

The fact that it has been around for decades, used by thousands of people, without tanking - SHOULD tell Softus something. Alas, Softus being Softus, I'm afraid it doesn't.

How many of you have used Aquapanel without tanking and had problems?

Speak up! (they won't).

And just how many reading this thread, have used it,do you think?

Well if they haven't used it - why are they commenting on its performance?

That would be like giving a book review on a book they hadn't read!
