Damp Wall Behind Bathroom Tiles - do I need to

Postby jeffrito » Mon Jun 04, 2012 4:19 pm

Hi there,

We've had a damp problem in our bathroom which has manifested with discoloured patches on the walls in the room directly below the bathroom.

I started to take the grout out between the tiles and found some of the tiles very loose which I have also removed. See picture.

The wall behind, which I assume is plasterboard, is damp.

Whilst there aren't any gaping holes clearly the surface of the plasterboard is uneven.

So do I need to replace the plasterboard completely or will letting it dry and smothering it over with plaster do? Or perhaps there is a different solution.

Please help!
