what adhesive to use to Fix a fibrous plaster cornice to plasterboard walls and ceilings?

Answer:

use bonding compound to stick the cornice, mix it up just like plaster adding the mixture to water, but make it quite thick so it will adhere better, if the cornice is fibrous plaster it will probably be quite heavy so using some plasterboard tacks to support the weight of the cornice after you have positioned them would be a good idea, otherwise they may move slightly under the weight, also remember too add the compound to the cornice and not the wall, putting large dabs on the both edges (ceiling edge and wall edge) DO NOT use normal plaster as suggested by someone else, other plasters do not have the adhesion qualities needed for holding heavy cornice work up, and if used will eventually crack where they have been bonded and may even come loose. hope this helps
