    Anyone at your paint store should be able to answer that question and recommend the proper paint.

    I have plastered. I waited 2 day to make sure it was really dry. Sure it's a good idea to paint it especially with plaster you've made designs with.

  • What did the plasterer tell you? If the humidity is high, keep waiting. If the plaster is not absolutely dry the paint will bubble. If humid, get dehumidifiers or at least fans to speed the process up. Also makes a difference if flat plaster was installed v. Sculptured plaster.


    Here are a couple helpful links for you. When I did my mom's house, with highly textured and sculptured walls, I waited 4 months over a long hot summer . . .

    It takes on average 4-6 days to dry. It is advisable to wait at least a week before painting new plaster. Sometimes it may even take up to a month for the fresh plaster to be completely dry. You should ensure that there are no dark patches on your freshly plastered surface before you attempt to paint it. A uniform light colour is a key sign that your plaster has dried thoroughly. Even if your plaster is only showing a couple of small, dark patches, you should only start painting when they disappear.


    A week may seem like a long time to wait, and it’s understandable that you may get frustrated with the delay. But, if you want to achieve the perfect finish, the wait time will be worth it. The time fresh plaster takes to completely dry will differ in every case. Factors such as the time of year, central heating, and how many layers of plaster there are will affect the time that it takes.


    You should make sure that the room that has been plastered is well ventilated. Opening windows and doors to let natural ventilation flow through the room will gently dry your new plaster. This will also help you to avoid the risks associated with rapidly drying new plaster, such as cracking.
