Hi,

I've recently re-plastered some areas of blown plaster (about 2mm
thick) and after two weeks I sealed the area with one part emulsion,
three parts water.

I then emulsioned, but now find there are a few little cracks showing,
and the paint is raised around the crack. There aren't many of them
and they are no longer than 1/2". Whilst not straight, they are
generally vertical.

Is this a symptom of painting before the plaster's dry?

Thanks

Gary
