Got a smooth concrete soffit to line, if I put bond it on first which would be best, just 2 coat over the top with bonding and multi or dab and skim?
 
Of the concrets good forget the bonding and just dab a skim bead up an hour before and just skim away. Blue grit first.
 
just to let you all know, I followed the majorities advice and dabbed it then skimmed it, site agent wasn't too happy, he said it was like walking through the new forest with all the props I had up holding the dabbed boards up to the ceiling. No sense of humour these site agents.
 
And here's a prime example of the dangerous side of TPF(registered trademark), chancers giving piss poor advice to people with even less knowledge.
@Danny I'm loving this dislike button.

I assumed soffits were external.

No, they don't have to be. In my world, a 'soffit' describes the underside of a lintel or maybe beam. But you hit on a prob I faced last week and was troubled. Plastering a bathroom with a stone lintel that had an internal and external face, i.e. it supported both courses of brick.

What's the best way? The issue is with it being under both (brick) skins, it is briding the DPC and could briing damp thru along with being a cold bridge. I couldn't remember having done one before and if I had, I didn't know enough about building to realise it. It was a dense dressed stone so I doubted it would draw moisture through the wall.

Well I assumed that by 'soffit' he meant ceiling as that's they're often called on plans and also the fact that the agent said "it's like walking through The New Forest" with all the props.
Personally if the concrete is straight and true I'd Gypbond and then skim but if they needed straightening then Gypbond, Bonding (8mm max) and then skimmed.

Thats the way I have done it in the past... in fact I had to skim underneath some concrete stairs and that is the way I did it...

Surely the spec would have it on :D
 
soffits an underside of a window as I usually see it.. not a full ceiling.. and thanks for your expert advive essex boy, really missed your wisdom..lol..
 
underside of a window is a soffit.. sides are reveals.. may be different in parts of the country... in Scotland their called ingo;s..
 
lol.. in sheffield a '' head '' is what a bird gives ya... its a soffit up here. thats what I;ve always been taught anyway..
