Applying tile adhesive

[townfanjon]

Plasterboard !!! , the name is the answer .

Um - no.

Don’t plaster the plasterboard!

Some dodgy advice being given here- maybe move this to the tilers forum as if I tell you how to do it properly everyone will say how do I know - I’m just a plumber etc ( but I do know )

No need move it, tilers discuss plumbing there.

I always thought for a bathroom the waterproof membrane needs to go on the plasterboard and then the tiles or wall panels go on the membrane????

Called 'tanking' I think

You need to register there it's a separate website but the guys there rock when it comes to tiling.

Grumpy; look if you’re going to take people’s hard earned money you ought to know what you’re doing....

In brief; yes tile directly onto plasterboard in none wet areas, wet areas either tank them or use a waterproof tiling board such as wedi, marmox, kerdi etc.

Apply adhesive to wall with notched trowel , notch size depends on tiles...

If tiles deeply studded or large or ‘bowed’ , also back butter the tile- in some cases will need to apply back of tile with notched trowel too.

Consider using a levelling system.

Consider getting a tiler in....

Tiling on bare plasterboard is entirely acceptable in dry areas as bare plasterboard will bear a lot more weight than plastered (As mentioned above). In wet areas, a cement based board such as Hardibacker should be used. In both scenarios an SBR primer should be used. Never PVA.
As for adhesive application, on walls, one or the other methods can be used, both is a bit overkill but with floors it's generally best practice to apply adhesive to the prepared floor then back butter the tile for better coverage.

Ben-gee, I couldn't agree more as far as tiling in wet areas is concerned. I'm just a retired guy labouring to an old friend. I've watched several videos on how to tile a bathroom properly (Roger Bisby and others). If I showed my mate your advice he'd just shrug his shoulders and carry on doing what he's doing. Thanks again for taking the time to comment.

I will just like to clear this plaster , not plaster situation up .
I have always plastered every bathroom I have ever done , not one problem . The reason they should be plastered is you have a chance of removing tiles off a plastered wall you havent a hope in hell of removing tiles off a plasterboard wall that hasnt been plastered .
We have all been there just wanting to remove a couple of tiles for what ever reason and the whole wall collapses and creates a load more work .
