We asked an artist to paint a mural on the side of the house. The artist used acrylic paint for the mural, about 4x6 feet. The background is water- based house paint, acrylic or latex (Kelly Moore).
Now we want to put on a clear coat to protect it from dust. I have a spray can of Deft lacquer and also some Deft liquid. Will that be satisfactory, or do I need something else?
