Sandy stuff under bathroom wall tiles!!??

[LanaGutie]

Hi everyone, first time here as a first time buyer in a flat where literally everything needs doing, and now I have no money, so DIY here I come!

So I've started on the bathroom, and have been removing the wall tiles, and they've pretty much been falling off in big sections, coming off with the tiles and underneath on the wall, is this kind of weird sandy stuff, the main bits on the wall are relatively solid, but some bits are soft like wet sand by the shore!

What is this please? What do I do? Will my place fall down?

Any advice, tips and tricks much appreciated.

Thanks in advance
Lana

Looks like water has penetrated the tiling/grout and soaked into old plaster, this will make it go crumbly. Your house isn't going to fall down but you might want to speak to a tiler and/or plasterer to get it put right.

It could be a bit of an ambitious project for a DIY'er.

Thanks for the relieving response! As long as it's not going to all crumble away, and its fixable, then im more then happy to get somebody in at some point. Thanks again 👍
