The Metal Coatings are ground metal suspended in a non-toxic water based acrylic binder. They may be applied to both metal and non-metal surfaces such as glass, wood, ceramics, concrete, foam, and resin.
The Metal Coatings are very durable outside (10 to 15 years) and are non-hazardous. One Gallon of Metal Coating will cover 100 square feet (this includes the recommended two layers).
The Metal Coatings are available in two different formulas – B and C. Patinas may be applied to both whether wet or dry. Once dry, either may be burnished with steel wool in order to highlight or adjust the patina. Additionally, more patina may be added after burnishing. Type C contains more metal than Type B and dries hard enough to be polished with a polishing wheel. Type C comes bundled with a catalyst and hardener.
When applying the Metal Coatings to ferrous metals (iron, steel, and aluminum), a primer must be used to protect the underlying metal
