Surfaces of antique copper objects can be imitated by using 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 (Gesso) or Pentart self adhesive glue.
This layer should be still slightly wet, when particles of the powder are gently pressed into it by brush. Drop alternately the Patina Effect Reagents to the surface for achieving different shades of patina. In order to receive the results of the process, it is advisable to perform trials.
