Hi all have just used Aqua defence on plasterboard wall in bathroom didn't see anything on tub about priming so just applied Aqua straight onto plasterboard and then tiled but just found on you tube that they say you should prime first I no it's a bit too late but panicking that it will peel off and fetch me tiles off any comments welcome. Thanks

Unless the plasterboard was very dusty or you hung heavy tiles, you'll be fine. Sleep easy.

The tiles are 660mm x330mm so are big lumps not grouted yet is there any way of testing can't sleep nights

You could get a suction lifter on a few and try pulling them off? You'll know pretty quickly how well they're stuck.

As already stated, they will be fine.
It's not a very big tile to hang off aquadefence.

Just rechecked the data sheet as I thought one of the selling points of Aquadefence was that it is ready to use. Plasterboard (internal surfaces only) is one of the substrates listed onto which it may be applied.
