Suggestions or advice on painting plaster

[Nosila65]

Sculpted GIANT teacup is finished and ready for painting.
It's had a couple of coats of One Coat plaster and a top layer of pink.
If anyone could advise on the best method I would be very grateful ! )

Ideally needs to be weatherproof for a short time/few days as its going to be on display in a show Garden here in the UK and our weather is rubbish at the moment.

I would use an outdoor masonary paint from bee and koo or another high st DIY chain

The problem with painting plaster is that it tends to suck the solvents out of the paint before it has a chance to form a film. To combat this, prime it with shellac first, using a first coat diluted with alcohol to half-strength and letting it soak in, and a subsequent coat that's full-strength.

Hi
I have found that the shellac coats are very important and will protect the plaster from water to a certain extent, then I have used acrylic paint quite successfully. However, outside in the weather (especially in England) it will only last for a while before the plaster starts to deteriorate.
