ive plasterboarded all my house ceilings with the grey side showing. i was told by a plasterer who came round to give me a quote, that the white side should have been showing.
is this a mistake or much of a issue, and would it make a difference when skimmed??
also it didnt say on the board wot side to use... manufacturer is GTEC
