plaster a ceiling

**amestaper** · 13-12-2008, 09:41 PM

I'm not a plasterer, but was asked to price a job at a plush new development where millionaires like to live. I thought the bill of quantities was sent to me to price for a taping and jointing contract which I would have loved to have done as I could have retired early

Anyhoo, much to my disappointment, the specs were 8mm thick bonding and 2mm skim of plaster over all the walls and ceilings. I'm no rocket scientist, but wouldnt the weight of all that bring the ceilings down?

you sure about the bonding? if it is onto plasterboard a skim should do it

Yes, got the bill of quantities here. Skimmed onto 12.5 mm plasterboard on ceiling over 600 sq metres of it then multiply by 4 houses.

'Plaster on plasterboard, butt joints filled with plaster and scrimmed; two coats plaster; 10 thick; first coat Carlite Bonding Plaster 8 thick; finishing coat Thistle Multifinish plaster 2 thick to BS 1191 Part 2; steel trowelled'

The walls are 10mm thick also 7mm & 3mm respectively.

Confused here I reckon 2 or 3 mm thick skim coat would have worked ok

Never heard of that one...... slightly confused why would you want to undercoat on top of plasterboard especially on ceilings,

Not my idea but Gilbert Ash's, and their clients job at Archerfield estate in East Lothian. I didnt understand why they wanted all that bonding but you know how those houses are down that area.
If the plaster wont pull the ceiling down, then the chandeliers will....

Any new plasterboard ceiling only requires a 3mm skim unless cowboys done the ceiling
