Hi everybody,

so I have finally started with destroying my old bathroom and now I have found this straw wall. I was thinking to tear this down and build new stud wall or to "glue" Tile mate backer board on this straw, which would be the easiest way to do it, but would it be the best way? The black spot in the middle is moulding straw which has been attacked by water penetrating through old tiles. What would you do in my place?

My thoughts would be to dry the straw and paint on that mould stuff you can get (can't remember the name) then render the straw before attaching backer or another suitable board.

But then this would be new to me so seek further advice and see if anyone else has a better solution.

If the straw can safely come out you might be easier to redo with new stud wall.

Also be careful when drilling into it if you have to - go slow and reverse the drill on the way out.

If it was me, i'd probably give it a good going over with SBR, then stick some moisture resistant plasterboard over it with dry-wall adhesive, That stuff's called Stramett board acorrding to my old man....how they ever got away with studding walls in it ill never know!

If i were you i would rip that down, I have the same walls (had the same) in my flat.

I pulled down 2 in my own bathroom & 1 in my kitchen, they are a bit of a bugger but they will come down.

I managed to put a reciprocating saw through them & took them down in sections.

The reason i had to take these walls down was so that i could put pads in the walls to carry radiators & a shower.

They werent very straight either.

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 ...:oops: 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?

i had those walls on a job last year. customer wanted to help so he stripped old tiles off the walls and part of the walls as well. i had to batten out the walls and cover in hardy, which wasn't a bad thing as there was quite a large gap between the bath and the basin unit which was made much smaller by doing this.

Do I have to batten the wall or can I just treat the straw with dry wall adhesive and then use hardy screwed and dot and dabbed?
Would this be enough? What is the best to kill mould?

What I will try is, dry wall adhesive forced into straw to bind it as whitebeam said and when set I spread flexible adhesive on the back of tile mate backerboards(12mm) and stick it to the wall and then I will use coarse thread dry wall screw (55mm)to screw it and hopefully make it secure. Does anybody see any problem in this?

If your going to use a flexible adhesive use the same addy to force into the stramit board rather than dri wall adhesive which is a gypsum product otherwise you would need to wait for the dri wall addy to dry and then would need priming before any cement based adhesive was applied...

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?

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 :oops: 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.
