Dot n dab or plaster concrete ceiling? Ask your questions and find answers on many subjects relating to plastering and dry lining

[firstinterior]

I have about 1000M2 of concrete slab ceiling to finish. I don't have the option of framework because of the clearance needed. Does anybody know the best method (gyp bond-it, float and skim) or (dot n dab and skim)? I'm also struggling for a labour rate to charge as it's not a very nice task.
Thanks for your help.
