plasterboard f##k up, bollicks

[HCMH]

Just had a plasterboard surround for the new fireplace installed. Came back from biz trip and thought it was ready to paint. Three coats and I can still see the main taped joint. Call the builders and they inform me that I should have put more plaster over the joint before painting. Can I sand back the paint to the joint, plaster then paint? Complete pain in the backside and lessons learnt: 1) italian builders never finish a job properly and 2) now I know what unfinished plasterboard looks like.

Any relatively easy fixes?

bks and thanks for the help.

You are supposed to use a drywall primer. Gyproc British gypsum do one. Google it to see the products. The jointing compound can affect how the paint dries.

Thanks, the paint has gone on very well but the joint is not perfectly smooth hence I can see the imperfections in the surface. Not that visible but not perfectly smooth either. Think I need to call in the experts.....more coin, gulp.

Lightly sand down and, using an interior filler, fill along the joint/offending area. Then sand down until flush.

It's not a case of it going on well. It's more a case of the plaster sucking the moisture out of the paint and eventually your paint flaking off.

Use watererd down emulsion first - 40% paint something around there & then go 70% & then 2 coats of 100% emulsion.
