Can you Plaster Over Painted Walls?

To know whether that was possible to plaster over painted walls I called my uncle. My uncle has been in the painting business for quite some time.

My uncle told me that I can transform a painted wall with a plaster coat, but there is a lot of preparation that needs to be done before that. 

Can I Plaster Over Paint?

My uncle told me about the steps that I needed to take to plaster my painted walls. Here are those.

• He told me to get rid of any loose or flaking paint from the wall.

• Next, I was asked to use sandpaper and smooth down the wall until it felt like it could be painted over.

• Then he asked me to apply a coat of the bonding agent. He also said that if another coat was needed then I should apply that. 

• After that, I was suggested to plaster the wall while the bonding agent was still a bit wet. 

After applying the plaster, he told me to give it enough time to dry.

Hello. I have undertaken several home renovation jobs in my career as I usually deal with changing the complete space, from decor to painting and more. I have been asked a number of times if can we do painting over plaster walls. Through this answer, I want to reach out to a wider audience who are facing the same doubt. So, here is the detailed information.

Can I Plaster Over Paint?

I would say yes, you can surely plaster over any painted wall. However, this is only possible when your paint is intact and in good condition. In scenarios where your existing wall paint is peeling off, you’ll have to remove the paint first. 

Can you Perform Painting onto Fresh Plaster?

I would say no, you shouldn’t begin painting over fresh plaster. This is because the nature of plaster is such that it will quickly soak up any moisture you offer. This would lead to an uneven paint finish on your walls. Hence, I would recommend you wait until the plaster dries out completely. In general, the time duration is 4 weeks, but you can speed this up with the help of external help, such as a heater or an open window.
