Skimming ceiling

i have just taken down polystyrene ceiling tiles and it has left a rough surface, is it possible to just have it re-skimed or would it need boarding first.

Hi not neccesarily re boarding but certainly it will need a bonding coat to cover glue deposits they will show through skim coat, hope this helps regards kevin

I am assuming the the rough surface left is polystyrene tile adhesive.
Check that the surface is sound clear of all polystyrene not flaking and no paper. Also check that the ceiling is not sagging or bouncy, if so the joists would have to identified and the ceiling re-screwed to pull it back up.
Then all that needs to be done is to have PVA applied, cracks and joints scrim taped up and re-skimed.
I hope this helps

it will be ok to skim your ceilling but it must have a coat of PVA first.

If the rough bits are no deeper than a few mm then it should be ok!
I would opt for either trying to go over the area with a scrapper or sander if needed and then PVA.
Im sure you dont need to overboard.

It depends.
if it's a sound plasterboard ceiling,then yes you could have it re-skimmed but if ceiling is of lath & plaster construction then i would definately recommend either taking it down or if it's pretty level then you can overboard first then skim.

Don't let anyone re-skim directly onto a lath & plaster ceiling.

Hi,providing the ceiling itself is secure you should be able to pva it and double coat skim.Regards Shaine

You will need to scrape the ceiling and get as flat as possible then pva and skim.or if not flat enough then overboard with plasterboard and skim.
