aqua board, tanking???

[bocean02]

I feel a bit daft asking but I've been reading a lot of threads which include talk of this 'aquaboard' and the term 'tanking', i'm kinda getting the idea but could someone please enlighten me?

Thanks again

Hi mate aqua board is a waterproof backing board that replaces the need for plasterboards and ply boards.

The backer boards can be used on walls and floors and it comes in various thicknesses.

The idea is you fit the backer boards then apply a coat of waterproofing paste , you then tape all of the joints with tape then when its dried you apply a second coat of paste.

The room is then water tight and ready for tiling.

Hope this helps mate

nice one mate I will investigate further, sounds great but expensive I imagine. Do people ever have the aquaboard with a different finish other than tiles?

I have to disagree slightly here. Aquapanel or other proprietory cement based backer boards are designed to be water resistant, as such they need no further treatment to protect them form water/moisture. It is normal to seal joints between boards with either the manufacturesr recomended filler or tiling adhesive. I have never heard of putting a further coat of "Waterproofing Paste" on them afterwards

coat of waterproofing paste

Maybe Essex Tiling could enlighten me as to what they use for this "paste". Please don't say PVA!

Here are some installation techniques for installing aqua panels......and for wet areas just replace the joint tape with water proof tape...to all joins and edges etc....

I agree with GG.
No need to put 'waterproof paste' ( I think he means to tank) onto aquapanel or the like.

Unless you are Mike Holmes, from Holmes on Homes that is.

Funny that G G as i run courses in tanking and have professionals in to teach this side of things and they all agree that although the backer boards are waterproof tanking them is advisable to make absolutely sure that it is 110 % waterproof.

Bit of a funny comment about the PVA as well mate.

My opinion is that if the board comes pre-covered with waterproofing compound, you only need to tape and proof the joints, and the screw holes.

If it doesn't, I'd tape and proof the joints and the screw holes, as well as doing two coats of WPC on the entire surface.

Alternatively, I'd cover the whole surface with a waterproof membrane, an example of which is Schluter Kerdi, which I've read some of the inhabitants of these forums use.

It varies though, as I chose system depending on the requirements of the of the job at hand, and what the circumstances are.

In the end, it comes down to what the manufacturer supplied instructions dictate. If they say "go forth and waterproof everything, and his niece", then that's what I do.


Saw a real cool system being used some time ago, which was sprayed onto the substrate. Thick, and perfect fit, kind of like my ex girlfriend

Anyways. Waterproofing is not an art. It's a science. The guys who design waterproofing systems tend to have a good grasp of it. Read their instructions and guidelines. Don't just storm ahead into the unknown without really knowing what you're supposed to do, as it'll return and bite you up the arse one day.



Cheers.

I have to confess Essex Tiling that I have only been in the trade a short time. This, however, is the very first time I have heard that a "waterproof" substance needs a water proof coating to improve it's waterproof-ness! Some thing is by definition, either waterproof or it isn't. Applying an extra layer over the top is not going to make it any more waterproof than it already is. Unless of course you are referring to the joints and seams which, if the manufacturers of the products instructions are followed, should be appropriately sealed and taped.

As for the comment about PVA, i was wondering if your "Waterproof Paste" was actually PVA based. Sadly you seem to have bypassed my question.
