Other ceilings safe from collapse after part of living room ceiling has fallen down?
My artex ceilings were skimmed about 10 years ago & now part of my living room ceiling has fallen down - just the skimming - you can see the artex now. My son's bedroom is above the living room so could heavy movement have caused the collapse or is it likely to happen to the other ceilings as I had the whole house down?
In my experience I would say that the artex wasn't PVA'd enough or at all prior to skimming.
I give ceilings 2 coats of PVA with a fairly strong mix ie 2 parts PVA to 1 part water, 1st coat and Slightly weaker mix for the second coat 3-4 parts to 1 water. Then apply plaster while tacky.
The plaster will separate from un PVA'd ceilings, if you tap the cieling with a knuckle you can usually hear the difference.
Hope this helps

And I think that skimming over artex ceilings is poor practice anyway.Every time this is done its possible that it could come down.Your plasterer should have told you at the time there was a chance this could happen.Over boarding is the proper way of doing it as far as im concerned and it isn't expensive.
