Can You Paint Over Interior Wall Plaster?
You can paint over interior wall plaster if you want to change the color of the wall. However, before you can do this, you must make sure that the plaster has fully cured. After you install new plaster, allow it to dry for at least a week before you consider painting it. The plaster has to cure and allow all of the moisture to escape before you put paint on top. If you do not allow it to cure, the paint will trap moisture and lead to problems.
