Surfaces of antique copper objects can be transformed using the Patina Effect Powder and Patina Effect Reagents. On the surface, create a layer on which the Patina Effect Powder is dispersed. Material of the layer can be primer paste or Pentart self adhesive glue. This layer should be slightly wet, when particles of the powder are gently pressed into it by brush. Drop alternatively the Patina Effect Reagents to the surface for achieving different shades of patina.
