Patio Paint is made to use on terra-cotta, plaster, wood and ceramic bisque. It is weatherproof and fade-resistant. Patio Paint is slightly thinner than traditional acrylic paints and slightly permeates the surface so that it will not rub or flake off as acrylics would do in time. All the colors are intermixable. A sealer is built into the paint, so a finish coat is not needed.
