I had some concerns about the wall base coat when I realized that it was a semi-gloss. Generally, it is easy to paint on flat, satin and eggshell finishes; it gets tricky moving into semi-gloss and gloss. In those cases you would usually want lightly sand or prime first. As this wall had only been painted a week before, the paint was still soft and I decided not to prime. Artists acrylics work well for indoor murals and go a surprisingly long way. You don't need the best grade. Student grade is fine. For most of the colors I went with Amsterdam, recommended to me by Artist & Craftsman Supply . The colors went on smoothly but required more than one coat. They also recommended Daler Rowney graduate acrylic for the white. It's a big jar. It has a sticky consistency that dries fast. It can't be reworked. You have to let it dry and then lay down another layer. I did like the texture it created but I might go with Amsterdam white for the next mural. ...
