What's the best course of action for this wall?

[theandroids]

Good evening all. Removed some tiles in bathroom and damaged the wall. Plaster has come off, underneath I think its bonding plaster? Haven't a clue.
What would be the best repair method for the wall, also can I installHardiebacker without plastering the wall after the repair?

Will be installing mosaic tiles.

Any help is appreciated.

I agree with waluigi. I have done the same myself. I also put a few mechanical fixings in too. But if you want to use the prowarm ...

What's wrong with prowarm?

MR board. Tank etc.

Sorry. There is nothing wrong with it. I didn’t mean to give that impression so sorry for that. What I meant was if you want to use prowarm ask them about what adhesive and what priming needs to be done they are best placed to advise you. I wouldn’t not use them.

Why wouldn't you use them?

I would use them. If you have them and they advise you best how to install

Had two walls like this on Monday, also was short on space due to architraves that could not be removed.

I primed walls with TM Prime Plus, then using my tiger trowel combed TM Ultimate over walls and stuck on 6mm Delta Board and made sure they were flat with a straight edge.

Next day screwed through them using 35mm washers and screws every 200mm, tanked one side as it was in a wet area.

Sorted.

Will be doing this after filling a few of the deeper gouges in the damaged bonding coat with Gyproc Easi-Fill.

Easi-Fill in deep gouges? Wrong product IMO. It’s a jointing compound and fine surface filler. It’ll take days to cure and once dry it’s poor for tile adhesive to stick to. Use thistle one coat instead.

Are you saying you are going to fill and then board over?

oh ok. Was going to use because it said for filling damaged walls.
