Just let it dry naturally, don't try and speed it up.. Don't turn any radiators on to speed it up either or it'll crack. It should probably take 3-4 days. It'll only dry quicker in summer.

Hi
Depending on plaster,but weather is I deal for plastering today don't worry it will be dry until tomorrow. Not need to do anything better let set naturally

typically 3-4 days dependent on the plastered background. Never force dry plaster as it will crack and delaminate.

I have seen it take from 10 days to 4 weeks so there you go , Dont force it that can cause cracking ,

I think it’s hard to answer this, it can take all different amounts of time to dry in all different locations, the easiest answer is. To let it dry naturally and let it go to a salmon pink.

Hi. definitely leave slightly open the windows will create neutural air recirculation that will helps to the plaster to dry

Like all of the tradesmen have said. Plaster drys naturally. Don't force it. As it can shrink and cracks. Just like in rendering and pointing in certain situations. Hence why we add pva to certain substrates. So they don't dry so quick.

Should Always let plaster dry naturally. In the summer 2/3 days winter 4/5 days if you try to speed the drying time you will tend to see cracks

Allow time to dry naturally this may take 3/4 days in the winter, should go to a pinky white colour when dry
