Can I tile on this

Hi all, I'f the above link works, can you have a look and tell me what you think, I have pulled one bathroom tile off the wall, and it looks like the person before me has tiled over wall paper. If I strip this all back does the plaster that's left look ok to tile on if I seal it first, it's not plasterboard? It's an old house. I'm not sure how the walls were finished back in the day!

I wouldn't tile onto that.

I'd also consider pulling the other tiles off before they fall off! Looks like the lot could be crumbling.

To be fair, it took some chiseling to get it off! So what do I do then? If I strip all the walls and clean it all, then what?

 

[Boogi]

Hi. So if I strip the wall bare, and am left with the base layer, what do I do then?

What is beneath the render, blockwork etc...

Hi, i'd recommend to pull all tiles off.

 

[Boogi]

Block work I guess, can I tile on that if I seal

 

[Qwerty]

Pull all tiles off. If you overboard the walls properly you should be ok. I would never tile onto that render coat though
Those cracks look worrying ....... had the cracks transferred through to the tiles? When was that top layer of tiles put up (roughly)

Hi, intend to pull off all the tiles, I'm retiling the bathroom. No cracks at all on the old tiles, and I should think they have been on at least twenty years. .....this is all going wrong, do I need to take it back to block, and overboard with what... Any reccomandations welcome. Ps... How do I fix the over board to the wall

Looks like a lime mortar. The only way to cure crumbly walls is to chip back to the block and dot and dab plasterboard or sand cement render, depending on time constraints.

How old is the property.....

The same as Wingn above.

I would take that lot off & DryLine (Dot n Dab) Plasterboard onto that to give you a nice smooth surface to tile to.

I think I will clear one whole wall at the weekend then re post, now I know I risk being mocked but...... Once the tiles are removed and all the loose crap,is removed what's left looks very solid.... But you are the experts so I will re post after he weekend, if you recommend I re plasterboard, but it seems like a lot of work, and I don't want to do I if not require .

It is definitely best to go right back to the block or brickwork. Then re plasterboard the walls prior to tiling. What type of tiles are you intending to use, if you are using heavy porcelain or stone you may have to use something other than plasterboard to prep the walls.
