How to tackle this straw board wall?

[xephar]

Hi I have the same wall in my bathroom its 2-3 inches thick of compacted straw, 2.5m x 2.3m area, my question is are these as strong as plaster board? will they be ok with Marble tiles?

I would pull it down, but tried to explain my better half:lol:, no chance and other problem is that on the same wall is boiler(where blue doors are) and it would mean I have to call gas bloke and just too much work and pain in the ...😳 there is not much space either so I will treat it with dry wall adhesive and then put the hardibacker board on it. Wanted to use tile mate board, but it seems to be too "soft".
What should I use to kill mould?[/QUOTE]

Fire should do it.
And solve your wall problem.#
And your gas man problem.

Yup, fire it. Then get your insurance company to rebuild it properly out of something other than dried grass :hurray:

Even this option got on my mind:yikes: But at the end I just used tilemate board and it looks O.K. Wait when the tiles will start falling down, so keep matches ready:lol:

In my opinion they are stronger but are pain it the 😳 Use marmox board or backerboard I have used flexible adhesive to stick tile mate board on to straw wall and to make sure i use plasterboard screws to screw it as well.

Hello. What was the outcome of this post? We have just started renovating our bathroom and found we have this and it's not in the best condition due to a potential water leak. Any help would be greatly appreciated. Thanks.
