Leave a mist coat on for about 24 hours to dry fully. A mist coat, which is a mixture of paint and water, is used on bare plaster to seal it. Ensure proper ventilation in the room to speed up drying. Once it's completely dry, you can apply subsequent coats without worrying about paint adhesion issues. This preparatory step is crucial for a lasting and even finish.
