Any surface that is not previously painted should receive a coat of primer
to insure adherence of the paint. Exterior latex is a good choice for
painting the mural as it dries with a protective, glossy coat that resists
dirt and moisture. In painting murals in the schools I have taught in, I
too have been curious about protective coating the work, but have been
advised by a number of commercial painters and paint manufacturers that
there is no need to add another layer of exterior latex paint. What can
happen is that the surface of the paint will yellow and you will not get the
true coloration of the paint that had initially been applied. Even UV
protective coating materials will cause this to happen as well. Murals that
I have painted using interior, semi-gloss finishes I have occasionally
applied an acrylic sealant to in spray form, but the use of a gloss exterior
latex eliminates the need for that.
