Tanking on plaster board

[Turkish tiler]

What is your views, tanking straight on to plaster board in shower area ?

 

[White Room]

Depending on the tile weights but yes many a time.....

 

[Dougs Third Go]

I'm trying to think of a reason not to?

 

[peteablard]

I have and I'd do it again with the free ardex tanking kit I got from the CTD trade day today!

As per Whitebeam, tile weight dependent, I would use PB every time.

So is it a waste of time/effort/money ripping out the old plasterboard and replacing it with Hardie/Tilebacker board then?, it's ok to just tank the old board (assuming that it is structurally sound and the surface undamaged of course), I think I have been overdoing it then!

In my opinion, yes, as long as the tile weight doesn't exceed that of the PB limits

very rare that you get a sound and undamaged surface though, especially if tiles have been on previously.

LOL, soooooo true, don't think I've ever seen it undamaged after removal, but if ....... then it would be ok.
