Powder Blue is a cold patina for bronze, brass, copper, and the Metal Coatings. This patina results in a stable opaque finish close to a bright ocean blue. Because of its stability once dry and sealed, it is a good choice for outdoor work. However, it should be applied indoors and requires at least 24 hours to develop. This is a very opaque blue patina. Clean the metal first as with any other patina. Spray, brush, or sponge on the patina. Do not apply in the sun. Let the reaction work for 24 hours. Reapply if a deeper color is desired. No rinsing is necessary. This patina may also be used on our Metal Coatings. It is not recommended for iron or steel, because rust will occur. Don’t use on aluminum. Set with a clear sealer when done
