    Hi all.

    I am hoping someone will be able to give some advice/confirmation.

    I am in the process of ripping out my bathroom and currently am removing tiles. Unfortunately they are double layered so getting them off is taking quite a bit of work and the plasterboards underneath are not surviving. Once removed this is what I will be left with:

    They are honeycomb cardboard strips, surprisingly sturdy however I am undecided on how to fit new plasterboard. My plan is to run vertical batons the same size as the cardboard ones and glue and screw them in place. I will then attach the new boards onto these.

    Is this a sensible plan? Would you do it differently? My main concern is that with just the cardboard batons I won’t be able to fix it solidly enough and it could all come crashing down once tiled!

    Many thanks in advance.

    Your "cardboard!" is a [much loved by Local Authorities] paramount partition.

    There will be vertical timber between each Paramount board.

    You will probably find that the paramount will not be totally "rigid" and prone to slight movement?

    To "enhance" your plan?? how about gluing the new plasterboard to the paramount??

    Ken.

    Thanks for the response, it’s interesting to know the actual name!

    Yes the paramount board do move a bit but are surprisingly strong. I didn’t want to fix to just them though as it could compromise their integrity, in fact I removed part of a wall with them in a few years ago and they just fell apart if you peeled off the top layer.

    Gluing to them as well is good idea though so thanks for that.
