Q: What is the best paint to use for a mural on a wall in my home?
A: Mostly, it depends on your preference. If you are painting
directly on the wall, rather than on a canvas you will affix to the
wall, then you must consider the composition of the surface. If the
wall is plaster, first apply a coat of matte-finish acrylic polymer,
followed by two coats of ordinary interior house paint. Paint the mural
on top of this. Remember to use matte-finish paint for the mural so
there won’t be a glare or reflection from any part of the room.
