My ceiling in my bathroom is rough , what im going to reboard the old ceiling leaving the old boards up and just putting new plaster board ontop
but im not sure if i need to get it plastered afterwards because of the steam?
or can i just fill the gaps and paint the new boards? will this be ok in a bathroom?

I've just reboarded and plastered my bathroom ceiling (previously rough/artex style). I'm not a professional but I would think your boards will need plastering. Plaster board doesn't like moisture and its rigidity will be compromised I would think? It's worth getting it skimmed. Alternatively, There may be a different type of board to use if you plan to paint it... does anyone know this?

Hi, you can do it twos, overboard and plaster or overboard and joint tape, the first option is well know to most DIYers but the second not so, ideally you'd use tapered edged boards generally 8x4 foot (2400x1200) but not a problem with square edges on ceilings. You boards on ceiling should have staggered joints, much like if you was building a brick or block wall.
Then you can either use the paper tape or nylon self adhesive scrim, the later is best for novices. Then apply these on joints, fill out with joint compound (sometimes called joint Cement) about 4 inch on joint. First application is really to get tapes flat and stuck to ceiling, then leave to dry gentle sand down and repeat this another two times broadening the width of the application on each occasion. Then sand down agian so nice and smooth and even. This will also need to be done in the angles between ceiling and wall. Then prime ceiling and use a paint that is suitable for bathrooms. If you use paper tapes the tape or joint should have compound applied before sticking it on.
