Sealing and Skimming Bathroom ceiling

Postby boardmatt » Thu Aug 14, 2008 9:18 am

Hello, This is my first post as I can normally find the answers to my questions in the forum!

I have just put up a new plasterboard ceiling in my bathroom, Unfortunately I did not use the green moisture resistant plasterboard, just the normal stuff.

I am about to skim the ceiling and was wondering if I need to seal the plasterboard with Gyproc sealant first? or as I'm skimming it and then painting it, is that enough to protect it? is Gyproc sealant used when people paint directly onto the plasterboard?

Or, should I give the plasterboard a few coats of watered down pva, like i have done when i have re-skimmed existing plaster walls?

You thoughts are most welcome!

Hi, you won't need to seal it until plastered and usually primer and paint will do.
You don't need to PVA plasterboard pre-plastering but if it has been plastered already a couple of coats of PVA will do the job.
Have a look on the project pages under plastering may give usefull info for you.
Good Luck with Project
