I am having a loft conversion done and builders have dry-lined study walls. They have skimmed but I can't see faint lines of the boards beneath in some areas although the wall is smooth and flat to touch in most area although some slight indentations in some places. Also in some places the joint tape mesh outlines can be seen. The skim looks quite thick as far as my untrained eye i.e. 3-4mm or so.
This doesn't look right to me and builders have said this is fine. Is this acceptable? Comments from plasterers most welcome!
As regards to sam's comment he is right in saying the skrim should not be showing above plaster. But i believe in your case it it's smooth and flat, it's just the colour the plaster has dried gives the impression it's showing.
