Making plastering good

[Damo1176]

I had a plastered in to plaster my conservatory and he has someone let me down. The thicknessof it from one end to the other is somewhat 5-8mm out and key focal points such as panel pins and a window trim make this quite noticeable, he informs me that there is nothing he can do and that he went with the line of the wall (NOT TRUE). Anyway cut a long story short I want to know what I can do to save it. Can I simply used builders caulk and try and mask the issue or can I simply bulk the plaster up bu using some quicksilver stuff or multi finish?

Any help much appreciated

you can pull it out with multie finish, he should of followed the frame not the wall.

Great that isn't a guy whose been doing it for 25 years cannot get a basic rule like follow the frame right!!

I am no plasterer but do you think I can do the mutli finish reasonably easily?
