"Removeable" Adhesive for Cement Board

[rideforever]

Hi, I am looking to stick some insulated cement board (2 cement faces with polystyrene inside) onto a plaster wall.
But it's possible that it won't work out and will need to be stripped off and the underlying plaster wall reinstated.
So I am wondering what is the best kind of adhesive / bonding / cement that I could use that would be possible to scrape off without too much trouble to make good.
Any ideas?
Cheers

Stick it on with foam.
A few screws.

Sounds convoluted. What is it that you are trying to achieve?

Sounds convoluted.

Sounds like a jackoboard, not something the OP is planning on making (if that's what you meant with the bold)?

Yeah that's correct and the product is quite inexpensive.
I need to put a little thermal insulation on. That wall is wind facing and is occasionally a touch damp - I've been told it is cold bridging. But if it is not then adding boards may cause some kind of mould growth behind.
Perhaps I wouldn't notice it, but you never know.
Anyway a double sided board seems like it would avoid any ingress into the board of any mould and its sturdy with good thermal.
I don't think I would use foam as scraping it off would produce foam dust which is not a good thing to breathe in. Maybe just a simple caulk would not be too bad.
Or an adhesive that "chips off" would be ideal ?
Gripfix/ silicone/ cement would be difficult to remove.

It wouldn't, but there are inexpensive solutions to this problem

If you have any ideas I would be pleased to hear ??

It sounds like you've jumped straight to the workaround rather than a fix.

Is it a cavity or solid wall? Some photos would be useful. Including the roofline.

Thanks, it's a 125 yr old victorian house, not sure it's solid or cavity. On the inside is plasterboards and lining paper. It's a cold wall wind facing. occassionally slight damp marks presumably at the dot/dab points. The dampness might be caused by damp wind getting into the sash window and passing behind the plasterboards, but I have triple sealed it with CT1, and there is an opening where the cord goes through. Little more I can do.
But it's cold anyway, not due to the damp, but because its SW facing, high and by the sea.
I just want to get those boards on without using stuff that would rip the wall behind if I had to remove them.
I got some cheap water based caulk this morning and stuck a few bits onto it as a test.

All sounds like a botch to me.

It may need repointing, or roof repairs. Impossible to tell from here!
