How long can I leave before painting a newly plastered ceiling?

Hi Bobby plaster wall can be painted as soon as there dry paint them with emulation mix with water 70% paint and 30% water that will give you the best coverage do this first then you can put what ever paint on after hope you find this usefull kind reguards Sam from P&S

the plaster can be painted after a day or two,Ideally you need to apply "crown covermatt "as this allows the walls to breathe allowing any trapped moisture to dry out,If you used a vinyl matt this would seal the plaster and trap any moisture so avoid! or apply a mist coat of contract matt ,wait a week and then finish in matt or silk emulsion

Hello When the whole of the area turns a light pink colour it's ready to paint. Mist coat it first in a contract matt. I find Armstead contract matt is the best but that's my personal choice.
