aquapanel in the bathroom

[Stephen]

Hello,

I've removed the old tiles from the bathroom and the plasterboard behind them. The plasterboard nearest the bath came off quite easily, so I wonder whether it was weakened by damp? What surprised me was that around the basin was similarly affected.

I am going to replace the plasterboard with aquapanel. It is a small bathroom and the long side of the bath runs along an internal wall. The short end across the external wall. The basin is on the same internal wall.

I will fit aquapanel all along the internal wall. What should I do at the end of the bath that is along the external wall? Should I fix aquapanel to that? If so, do I fix the aquapanel direct to the masonry or to battens?

I presume I can use plasterboard for the other internal and external walls, which are away from splashes? Or is it the general humidity and condensation that causes the problem?

I went to Wickes yesterday and bought some aquapanel. There was also a Knauf gypsum based tile board that was supposed to resist damp. Does anyone know anything about that?

I could not find any aquapanel fixings. What are they? Can I just use stainless steel screws instead or are they something more special?

Thanks, Stephen.

There should be a link to fixing methods.

I would fix to battens, you can get them nice and flat, and then when the aquapanel is fixed you have a nice flat surface for tiling on.

Get a bag of those plastic packers, makes getting the battens even easier than faffin about with little bits of hardboard etc.

Use moisture resistant plasterboard (green faced stuff).

IIRC they sell some ceramic coated screws or something for it, but stainless screws will be fine.

I'd fix with dot and dabs of cement based tile adhesive, then when set nice n level, drill through it and the dabs into the masonry and screw it all to the wall for belt n braces. Wooden battens waste space and are a pain IMHO.

If it's a cold room you could look into the insulated forms of tile backer boards?

What about the black coated ones used for plasterboard? Would they work?

Thanks, Stephen.

Yes, they will work fine to hold it up.

If you are concerned about the it getting damp and the screw rusting, then you might want to use stainless.

Personally I just used plasterboard screws. If it gets wet enough for the screws to rust and it becomes a problem I probably have bigger problems wto worry about

Thanks. I agree that there would be more to worry about in that scenario! I thought plasterboard screws had the black coating to prevent rust?

Thanks, Stephen.
