Hardiebacker and pvc shower panels

[Agstorags]

Hi all,

We are redoing our bathroom and have a shower enclosure with 3 walls . One wall will be hardiebacker boards over battens and the other two are bare plaster. I wanted to sense check a few things

Firstly the order of events. Is the below correct?

1. Attach hardie backer cement boards to battens with screws
2.Tape and fill seams
3. Apply water proofing product https://www.wickes.co.uk/Mapei-Mapelastic-Aquadefense-Waterproof-Membrane---7-5kg/p/114253 to two bare plaster walls
4.Attach shower wall panels with adhesive, trim and sealant as described in shower panel instructions https://images.victorianplumbing.co.uk/images/pdf/VPWP-2410-LGMC_Ins.pdf

Also if I use below product for taping the hardie backer seams can I also use as the adhesive to attach shower panels (step 4)? If not what product can I use?

Hi,

I have almost done the same as you, but went for tiles, rather than shower panels.

Some of what you are doing may be slightly OTT, given the water proof nature of the shower panels!

But, for a belt and braces approach, it should really keep the water out!

For me, I continued the tanking over the hardiebacker boards (they are water resistant, not waterproof!).
Stainless screws are best for the Hardiebacker, given its alkalinity.
I also bought a full tanking kit:

It includes a a plaster primer and a flexible waterproof tape for joints, corners and the junction with the shower tray.

Apart from that, it sounds good!

Thanks! With regards to the plaster primer what does this do?

Thanks! With regards to the plaster primer what does this do?

It seals the bare plaster wall, stopping the suction from the new plaster.
The tanking solution then sticks to the wall, rather than drying out too quickly and peeling off!

Shower panels will glue on most surfaces as long as its clean and dry. Just used the correct adhesive on mine.

Thanks, any advice as to if what I've linked to would work for taping seams in the cement board?
