Tiling on walls after old tiles removed

[Matt0029]

Do you think it would be ok to tile over this wall after the removal of the original tiles?

 

[Matt0029]

Or would you recommend getting it skimmed?

Its cheaper to skim it than throw loads of adhesive at it , quicker to tile if can gauge
Is a bit rough i wouldnt want to tile it
Doesnt need to be polished skim for paint can do it yourself

Prepare the wall by removing any loose materials or paint, If necessary, apply a coat of primer to the wall.

The other side is worse the above wall is papered as I believe the wall isn't good enough for painting

Should be able to knock those adhesive blobs off from the previous dot and dab tiling (considered of the worst type of tiling going). Then apply adhesive using a trowel next time and you wont get those off so easy.

What's your end aim here?
