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

[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.

If you are installing mosaics the wall needs to be perfect , knock off and reboard, I wouldn’t bother with hardie , its a pain imo and plasterboard is perfect, if its in a wet room , tank it

Installing mosaics - put the effort into having a perfect surface to tile on. Will save you so much when tiling.

not looking to knock back. Its too much work and the wall is where a window and toilet is.
Just want wall as flat as possible to put some type of backing board over.
Do you recommend multifinish over surface or another product?

what product?

Is the bonding sound? If you have a window and reboard are you happy with the extra wall thickness around window ?

The trouble with any plaster finish is that the surface flatness is unlikely to be good enough for mosaics. Another method is to dry line with Orbry board with supplemental Orbry Spanker mechanical fixings. Boards are waterproof so use waterproof tape on joint for wet room. Boards incorporate insulation so reduces risk of condensation (always include forced ventilation in bathroom) and mouldy grout.

As shown in the pictures its pretty much just parts that have come off and texture in some places so not smooth. Was thinking of filling damage then getting flat as possible, then 6mm backerboard. Just need to know what product to fill holes and over the bonding to get smooth as possible.

Thanks already have some prowarm boards. Is yours better?

To be clear you want to get wall to a decent finish before reboarding with plasterboard or a backer board?

If so don’t bother, reboard on what you have and get that plumb and level

Do i need to PVA the bonding before applying the board using adhesive?

 

[acaciaguy]

what adhesive are you using ? What boards are you using?

Hack it all off down to brick/block and Dot and Dab Plasterboard.

Messy but worth it when you consider you can achieve a perfectly Plumb wall and smooth surface to tile on to.

Not an option for me. Also, the wall is not damaged enough to warrant all that work.
