Tiling to plasterboard

Thespoofer

Im in the middle ( well early stages) of renovation my own bathroom.

I tiled it 12 years ago directly onto plasterboard and realised recently when stripping it the plasterboard would come away too so it had to be reboarded again which I've almost done.

Question is, to prevent this happening again when changing tiles ( which will be enevitable), would it be wise to screw tile backer board over the new plasterboard, then tank and tile or is this over the top?

Any advice would be appreciated.
Thanks.

Over the top really in my opinion. I wouldn't screw tile backer board to plasterboard for walls, instead if there's water present such as in a shower or bath with shower I'd use cement board instead of plasterboard and greenboard (moisture resistant plasterboard) for the rest. Cement board is not water proof so anywhere water is present I'd tank the area also.

You could also go for that new foam board such as Schluter Kerdi board, it's very light and easy cut and has the advantage of being water proof but pretty expensive stuff. You still have to seal the fixing which require large washers given it's just foam and without them screws would pull through.

I wouldn’t be that worried about having to replace plasterboard as it’s relatively cheap and unless it has gotten wet it should be possible to remove tiles without damage.

Re Kerdi system you don’t need Kerdi board if you already have new plasterboard in place. You can get the cheaper kerdi membrane. I’ve just done a whole wet room in this. It’s still expensive for what it is and it’s a lot of work for diy if you’ve just got evenings and weekends.

My advice would be to research the fibreglass spray systems and get the pros in. Then test it before tiling

Do what you are doing. In another 12 yrs, just repeat the process. Easiest and cheapest option.

Plasterboarding is cheap as chips. Just tank the board be done with it.

Why not use tile backer board rather than plaster board, much more stable and nice to tile on to it. You are not relying on cardboard to hold the tiles up.

Way too expensive, time consuming, and same problem faced in another 12yrs !

You won't be able to prevent it and plaster board is so cheap and easy to replace it's actually better to resheet as you get a nice smooth surface to tile on.
