Crack in plastered wall

[vrytir]

Hi

I have crack in plastered skimmed wall, what should I do? Should I take any action to repair it? Or should I just leave it and tile on it anyway? I send you picture later.

And this one as when I touch it it is moving so I guest it will need repair

I would tap the walls where there is cracking,there's a good chance it may need removing as well....what tiles will you be fixing to the wall.

Ceramic tiles 25x50cm

If you find that the crack is in the brickwork behind the plaster, check outside to see if it travels to the exterior....
