    I'm just about to paint a freshly plastered room. The plaster is dry. I am just wondering is it better to give it a coat of polybond water or a coat of watery paint to seal it up first?

    DON'T USE POLYBOND.Use watered down matt emulsion.

    Have you ever tried painting over polybond? The paint just sits on it and takes forever to dry.It will take more coats than needed to cover it and is not needed as a thinned down coat of matt emulsion does a better job and is a better base for over painting.

    will the plaster not draw the moisture from the paint making it chalky and prone to flaking?

    Thin your first coat down well. 10-15% with water. Don't worry if its watery. You must get soakage into the new plaster. The plaster is dry and needs the paint to bond properly with the new plaster. if you don't do this, when your filling small cracks or imperfections in the plaster and start sanding the filler, the new paint will start to break up. The main problem comes later on in your kitchen and bathroom ceilings. Condesation and steam will lift and crack the paint of the ceiling if it has not been properly undercoated with the 10% thinned mix. This usually happens 5 or 6 yrs down the road and you will have to scrap all the old paint off and re do properly. Don't mind unibond or polybond. That's really for mapping or over troweled new platered walls. All you have to do is prime/undercoat with a 10% thinned mix of regualr paint. Saves peeling problems in a few yrs time.
