Looks damp to me. Whats on the other side on the wall?

[ShadownINja]

Damp (complete guess from clueless non-DIYer).

[benmc]

Just reread

'A wall between our bathroom and stairs'

plus looking at the colour of the plaster. I am 99% sure it is damp. I guess something is leaking from the bathroom on the other side.

My dog went through a faze when he would eat the plaster where he slept.

Look like scratch marks, so there is probably canine involvement. Also looks damp, which may be attracting the dog.

Defo a leak from the bathroom behind that wall, plaster looking very damp.

Look at the other side of the wall take a measurement from the return wall of the turn of the stairs and look in measured vertical plane in the bathroom and then work out where it can be coming from.

Check from the top down, i.e. tiles still sealed, mastic seal still in place on the bath top surround, etc etc.

Good luck.

EDIT: Oooo I can see a shower tray in the first picture, height wise i'd check the lowest few rows of tiles/shower tray seal to tiles.

Is this guy the other side of the wall??

As has been said, that plaster is absolutely sodden.

Your shower is leaking.

If you have to replace the bathroom wall make sure you use moisture resistant plasterboard!

[CedGTV]

I would of said that the wall in question is brick/block built with a browning/bonding/skim tight topcoat.

I've been using a 6mm Wedi board with taped joints to be used a waterproof undercoat keycoat for the tiles on top.

My money is on the mutt.
Even if you got water ingress (not damp) it still wouldn't do that.
BTW, is that pi55 on the wall?

Set up a video camera to see if it is the mutt.

Woof..

Some good products here to solve this.

sprinkle some chilli powder over the affected area. Dog won't go near it again.

Exposed plaster definitely looks damp. Dry finish plaster is light pink.

The marks do indicate some canine intervention though. I might be imagining it but I think dogs do like the taste of plaster.

Perhaps repair and make dog sleep elsewehere for a little while and monitor. Alternatively there are sprays available that dogs don't like the taste of which you could use on the effected area.

It maybe body parts buried in wall that the dog is after

Im reckoning that its been treated with pva, hence the damp look.

Agree with the rest of your post.

I thought it, you said it.

Might be a bit obvious but is the shower unit on the other side of the wall. Could be a leak for the unit or the pipe work maybe.
