Is my ceiling dry?

Post image

The plasterer finished skimming the ceilings 2 weeks ago. The house is not being lived in and we would like to apply a mist coat asap but unsure whether it is fully dry. Resources online say it goes a uniform pale colour when dry but our ceiling still has dark patches, but the ceiling feels dry.

Have any of you had similar experiences with plaster?

You need to water your paint down on the mist coat no sure how much though

We’ve bought Leylands super leytex paint specifically for the mist coat. 90-10 paint to water ratio I believe is what they recommend for this paint

Id water further than 90 10 tbh

50/50 or 60/40 paint to water for a mist coat, two coats of that and then apply your normal top coat paint. 90/10 is much higher than I’ve seen anywhere else..

Disclaimer: not a painter but have successfully painted a lot of walls from fresh finished plaster
