What happens if you paint plaster too soon?

Asked By: Spacedman Date created: Jun 22, 2022

Painting plaster before it's fully dry can cause the paint to peel, giving you endless problems, but some bare plaster paints allow the plaster to continue breathing and drying after the paint's applied. Sometimes patches of new plaster don't dry out because of damp. The cause of the damp should also be addressed.
