Removing tiles

[Woody123]

Hi all,
Just had a call from a customer who wants me to go round and have a look at something. He has started removing tiles from stud walls and he said its not plasterboard it is an older style building material that is like cardboard on top of an egg box?!?!?!?!?! I have told him my initial thoughts are that this is not suitable for tiling onto anymore and it would need reboarding with plasterboard or something like auqa board, just after a little advice as to what you think it is and if there are any other options other than reboarding as i will be going round his house tommorrow to advise what is best.
Cheers

It will be a unit of plasterboard on 2 sides sandwiching a honeycombe, if you like its like a flush door but thicker. It was known as paramount partitioning and has been around years.

There will prob be a batten at the top and botton on ceiling and floor to which it was fixed.

You can not take the boards off as it is made as a unit so pb over the top would be the alternative I believe

Yes, that's what I'd do, board over it and away you go

have you got any tips for dot and dab? what tools and materials will i need? is it fairly straightforward

wetdec is right, The paramount is the whole wall, If you take it out thats the wall to the bathroom and possibly a bedroom aswell. Paramount is only a couple of inches thick so it's not about taking off the board one side and dot and dabbing, But if the damage to the board isnt that bad you may be able to patch up with plaster Or dot and dab on the existing board.

your best bet is batten out over existing wall and fix backerboard, Hardibacker, if space allows and tile ontop!

Cheers for the advice people. If i was to batten out would i space the batterns the exact same width as the plasterboard? Or someone says if damage is not too bad then patch up with plaster or maybe rapid set? would that be suitable to tile onto again?
