Hello @oliviaoneill
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your indoor wall.
I suggest cleaning the wall and using a grinder with a wire wheel paint stripper. This will allow you to remove all the paint on the surface. If you are planning on painting the surface, I recommend using Gyprock CSR 20kg Hardwall Plaster. This will allow you to produce a nice even surface which you can then paint over. Please remember to wear personal protection such as gloves, goggles and a mask when using the grinder.
Here is a handy step-by-step guide: How To White Set Internal Render (some of the techniques used are applicable to your project)
If you need further assistance, please let us know.
