New plaster cracking - Advice needed.

[armour]

Hi all, This May I had a plasterer in to replaster the walls/ceiling of my bathroom. It seemed OK so I paid him off, tiling & decorating 3 weeks later. - Now 5 months later large cracks have appeared in the ceiling and walls. I'd like some idea as to the possible cause(s) of the cracks before I confront the plasterer. Can anyone help? [/img]

Where are the cracks, (position and background) and what did he use (skim, or bond and skim, sand and cement etc)

As stated, much more info needed & some pics. might help. Were there any cracks there before? Are the new cracks in the same place? Do you mean large as in long or large in width? Was any new plasterboard used? Do the cracks coincide with any joins in the plasterboard? What preparation was done before the re-skim?

Hi all, thanks for the prompt responses I don't know exactly what he did prep wise I'm sure he didn't use plasterboard though. The cracks are in the ceiling (previously artexed) and in 2 opposite walls the worst being at the join of 2 walls,see pics.

The vertical crack looks to me as if a joint in a plasterboard wall has cracked. The crack in the ceiling, (which you say it was previously artexed) might have been there all the time, and he never noticed it, and just plastered over the artex, and the crack came through again.
Is the ceiling lath and plaster?,, and was any work carried out above it (loft/roofspace or whatever), after it was plastered?

If he done both walls and ceiling he SHOULD have scrimed the joints in both. As i see it he did not scrim the joints therefore that is why you have the cracks in the plaster work. If this is the case call him back to put it right. S/S

The odds are the ceiling is knackered - that's why it was artexed in the first place. It's continuing to crack as plaster isn't flexible. He'll just say that it isn't his problem. You may as well just fix it up yourself with caulk.

Cheers for the replies, I really appreciate them.

The pics help a lot but you didn't answer this;

Were there any cracks there before? Are the new cracks in the same place?

& another, did he plaster over the original Artex?
