If a truly maintenance free exterior is desired an acrylic finish coat can be applied instead of paint. It is synthetic stucco and is available in a variety of colors and textures. After the masonry stucco has dried and cured, acrylic is trowled onto and over the base coat in lieu of paint. To change the color of your house in the future, normal house paint or Elastomeric paint can be applied over the acrylic finish.
