Liquid tanking and how it affects weight limits..

[One Day]

I use ardex wpc pretty much all the time, but if I had to tile upside-down (and I am soon) it will be on wedi or kerdi board where the joints and Fasteners are sealed.
I don't have confidence on any liquid system on paper faced plasterboard.

Didn’t find it difficult Marc, just found that it tended to be a little thicker than the single part tanking systems

Oh I’ll agree there, 100% John, no question.
That being the reason I have more faith in that than the generic grey paint type.
I also feel that it’s far easier to have thin areas with the grey (light blue) paint, cos there’s not enough contrast with the substrate on occasion.
Whereas with the Ardex, there’s absolutely no denying any areas that are too thin.
But then again, lately I’ve been using Isomats SL17 a grey paint type! 😀
It does feel more robust tho than some I’ve used though. 😛

There is a ctd about 45 mins in the wrong direction from me, nothing near by really, unfortunately. The worst I’ve seen for peeling was one that went on white and dried clear. Im not sure on brand but a contact I did some jobs for used to use it and had a few issues when I had to re do some areas.

Could we ask all the suppliers to add to this thread.
Isomat did mention in an earlier thread that it does lessen the final tile weights and I realise that it’s all down to preparation.
However I’am sure the people preparing the 2 examples I noted felt that the thicker they slapped it on the better the tanking!
IMO tiles are getting too big for this method of tanking and it should be noted on their packaging - just like ready mixed tubbed adhesive give the info now - not for porcelain or tiles over300x300mm.

exactly as Antonio does. To make no mistake, use mapelastic. more work. but more security. amen

I’m keen to see what Tilemaster say. I would also like to know how these sort of tests are carried out

Ardex

Tilemaster. @Glynn

and yes, I see all the manufacturers responding.
hard life in the laboratory.
you should perhaps go out of the office and go to work sites.
something is always learned.
and now, it's cold ... better to stay in the office.
sorry

I looked into this a while back. Ones I've had experience in.........

BAL Tank It, no effect on weight limit
Ardex WPC, no effect on weight limit
BAL WP1, reduces max weight limit to 32kg's per sqm.
There were a couple more but can't find the replies.

Got more suppliers I can speak to. will try and rustle up a list if it helps.

Thanks for the updates.

I'm going with ardex next. Use Mapei usually, aquadefence through preference but mapegum if client supplies.

Interesting thread on liquid membrane.
If im not boarding the walls, i insist on the builder leaving them as they are, no skim or jointing tape, just bare plaster. i use a liquid membrane and corner taps, pipe collars etc...
i worked in Norway for a while, all bathrooms i worked on were finished with plasterboard and tanked with liquid - schoenox was the brand we used. very thick but brilliant to work with, even tanked inside the plasterboard box section that was to house the geberit frame for toilets and basins. No cowboys out there, bathroom specs are controlled by the insurance companies. No ticket....no tanking!!

Don't mind me while I bump up some older but good threads. If you can contribute to the thread, go ahead. But if it's nothing for you then don't reply and it'll soon drop off the What's New page etc.
