overcoming bad paramount walls

k13wjd · 26 Jul 2010

right, i have a problem - i have paramount walls, and i need to fix up them up ready for tiling.

do i a: remove the offending boards, and put new ones up
OR b: dab+dot new ones on top of the old ones?

If its a: will a skim of drywall adhesive on the back of the board be enough to grab the paramount card ?? Or will it be a job for MR unibond pva ?

if its B - whats the minimum depth i can put the new board at. By that i mean : after i put the board onto the wall with drywall adhesive, how far can i push it to the old board ?? 5mm ?? 10mm ???? Needs to be fairly flat for tiling of course.

What are paramount walls ?

k13wjd · 27 Jul 2010

the work of the devil.

its a sandwich. The bread is made from 9mm plasterboard, and the filling is cardboard.

crikey, best thing is to pull the bloody thing down and create a proper stud wall. how heavy are the tiles you are planning on hanging? Do you tihnk the wall would hold them safely?/

that's not an option - as it would involve removing BOTH sides of the wall, thne having both re-plastered... = £££££

I know what you mean now , i know it may cost more but i would seriously think about taking it down and building a proper stud wall ,you could build it and do what you want to in the bathroom and then get the other side done when you have the cash.How much area are we talking ? it wont cost much just to have a bathroom skimmed and the other side of the walls too (or it wouldnt if i was doing it )

the other side of the bathroom forms my stairwell.

Its not in the budget to have that done - so its dab+dot over the old stuff i'm afraid.

and all the walls are like that in my house - so its always been, and always will be a problem.

My nick name is wozza too - warren ?

I wouldnt DnD on to anything other than a solid wall, if you were considering DnDing onto it will the tiles not be safe on there? or is it in bad condition? if its structually sound and just shabby why not just put a skim coat over to flatten it out? it doesnt need to be perfect to tile onto. a DnD then tles ont that would be a bit heavy i would have thought

Please use some common sense here mate, if it isnt in the budget then it will have to come out of the contingency fund, if you dot and dab the construction of the paramount isnt gonna hold the weight of the extra adhesive and board safely is it, then you are going to add additional weight of tiles, tile adhesive, grout, this is asking for something bad to happen. You need to build a suitable stucture for the application, are you gonna feel safe walking up that stairs with all of that weight resting on a 2" batten which is 8' long and only fixed at either end.

Is there no room to put a freestanding studwork frame - useful for insulation and pipe runs if there's a shower going in there?
