tiling

Hey,
I'm about to retile my bathroom.
I've been taking off the old tiles and lots of the plaster board has come off.
Can i use the adhesive for the new tiles to fill in the holes (some are quiet big and theres a fair bit of plaster board that came off).
Or will i have to pull off the remaining plaster board and put on another one?

Cheers

this is real pain in the ass. just keep taking away the tiles and at the end see what type of damage is done to the plaster board. if the holes are bigger then the tiles you might need to change the portion of plaster board (consult with tiler asap ) it will defiently be an easier job for the tiler with new board

When we tiled bathrooms we just tore it all down and replaced the plasterboard. It's easier.

Bear in mind if you have patchy walls it can be more difficult to get a level surface.

If the damaged walls are in a wet area such as in around a bath or a shower I would rip out the plasterboard and fit marine plywood and then tank the area, this will give a perfect waterproof area , if you dont want to go down the road of fitting plywood I would replace the damaged plasterboard with new plasterboard and tank the area , tiling over damaged plasterboard is a recipe for disaster.

the quickest way to take tiles off is take plaster board off then put up new plaster board

As above - replace the whole lot, tank then tile.

yeah, figured thats what people would say.
trying to take off plasterboard in sections.
Have bought water resistant plaster board that i will cut up and use to fill in holes.

Thanks everyone

First thing to do is decide if you want to re tile your bathroom in 5-10yrs..? If not then, re slab your walls and use a proper tanking system. Oh and theres no such thing as water resistant plaster board or water resistant grout.

No such thing as waterproof grout but water resistant is what it's called.

yes there is. the green slab is the moisture resistant one

Well for what it is worth. I would take off all the tiles see what the damage is and then I would buy a bag of bonding and rebond the wall so that it is nice an smooth for the tiler to fit the new tiles on. Well fitted tiles done by a good professional will not have any issues with water getting behind them.
