I've just put a new plasterboard ceiling up in the bedroom. I used square edge board and filled the gaps with Polyfilla, smoothed it down with fine sandpaper, primed it and gave it 2 coats of matt emulsion. Problem is the joins still show quite a lot. Even though I thought I had got the joints quite smooth I think the light coming in through the window makes the joints look more raised than they actually are. (That's my excuse anyway).
The question is what can I do to improve it. I'm thinking of going over it all with thick backing paper and repainting. I'm not sure how well it will stick to the newly painted ceiling though. Anyone got any thoughts or other suggestions. I thought of maybe stipple paint or a heavy embossed type paper but the missus wants it kept smooth.
TIA
