Plaster kitchen ceiling or overboard?

[dormermike]

Hello

Kitchen ceiling was wallpapered and have removed that with a view to painting it. I can see lines - are these the joints between the boards and how can I prevent these showing through the paint please ?

I did have a plasterer around to quote for skimming before the wallpaper came off and he advised getting it over boarded. The condition looks good to me, so I don't see the point in overboarding unless I'm missing something obvious ?

Also i'm assuming i need to wash the plaster with sugar soap to get the wallpaper paste off, is that right, before mist coating then paint?

thanks
Mike

Sand, powdered filler, sand. Repeat where required.

Brush on Zinsser Gardz, allow to dry, then emulsion, then allow to dry. Fill and sand as many times where necessary, then emulsion enough coats until you're happy with the finish.

Sugar soap is outdated.

Over board it, it adds extra fire protection.

Thanks.

Had a plasterer around and he is saying not to overboard as not needed, as the ceiling is in good condition. Just needs a skim. He reckoned there is negligible improvement in firerating with overboarding and it won't cut down on noise transfer either once the 15 down lights are in.

Overboard half, skim the other half!!

I disagree with your plasterer, I removed all my downstairs ceiling, fitted insulation and double boarded all the ceilings, it has now added up to 1 hour fire proffing and there is no noise transfer.

He probably suggested overboarding to save getting the paper off.

once the 15 down lights are in.

Making 15 holes in your ceiling will of course reduce fire protection and increase noise transfer
