Hi,
You may remember I was asking about swapping an electric shower recently. Well the plumbing and electrics all were ok thanks to the help I had from you here.
But: the tiles were tiled onto plasterboard and a tile was missing and a couple more were cracked. I guess that water has got in through these and the plasterboard has turned to mush.
I will rip it all out but I am unsure what to replace it with. OTOH I worry that if I use plasterboard again, the same thing will happen but OTOH the damaged PB has probably been there for thirty years so it lasted quite long. If it lasts that long again, everyone will be happy.
Wickes haven't got any aquapanel in stock locally and it is very expensive, so I can't use that. I did wonder about 12mm WBP. but would plasterboard work?
I have typed "tiling onto plasterboard" into google and found 101 forums where some people say you can tile onto plasterboard and an equal number of people saying you can't.
Then half the people say use PVA and half the people say don't!
So what should I use as a primer? PVA? Emulsion paint? Branded product?
Help! It's giving me a headache.
TIA
