Can any advise please
I don’t do much tiling, I’ve got to tile the new bath in.
It’s plasterboard walls. Is there a paint on treatment to use first before the tiles go on?
Cheers all

I just mix a quantity of PVA glue as a weak mix, to act as a bonding agent. Once that's applied to the tiling area boards and dry (one hour should do even in winter), then tile on top of that.

not suppose to use pva and then tile. You can tank them with a special paint or remove plasterboard and use hardie backer boards or wet room boards.
If tiling direct to plasterboard you can get away with it but i probably wouldn't use pva.

I’ve seen & been recommended the Mapei tanking system. I’ll probably use that. It’s only for where the shower will go plus I’ll extend it to other splash areas around the bath.
It’s only paint on with tape for corners or joints.
If the tiles split the plasterboard then I’ll have a rethink as I’ve never cut plasterboard out & refitted it or cement board.

God yes, never PVA its the worst thing you can use. Acrylic tile primer or the Mapei tanking as mentioned by aj.
Use powered adhesive as well not the ready mixed rubbish.

I used a Hardibacker cement type board on two showers in Puller Towers. Then I tiled it, what great stuff, would never use plaster board on a shower ever again.

I did it this way:
but I do know ideally you're supposed to use cement board or even better the really expensive proprietary tiling boards.
I do wonder though how much of all this is manufacturer's vodoo to get you to spend lots of cash with them. I reckon a shower is going to start looking dated from 10 years old and then pretty grubby at 20 years whatever you do so I do wonder about all this tanking stuff.
Maybe cement board and the rest are better because they don't flex like plasterboard does so easier to get flat tiles ?

It’s another one of those those jobs to me where I can say ‘is that it?’ When someone used to say this or that needs tanking it sounds a big serious job. Very simple it seems these days. Cheers all |

Wet Rooms in any house with a wood floor are a complete disaster, too much movement. Much better to have Low Rise Shower Tray, Cement based board on the walls, Flexi tile adhesive & Grout.
