This simple technique that gives fascinating and expressive effects is performed in three phases:
- Roll out the light base and let it dry.
- When the wall is dry, spread the darker color with a brush and paint rather large areas.
- When the color is not yet completely dry, wipe with a rag in all directions to create controlled inhomogeneities.
There are paints made with natural colors that, if used with this veiling technique, help to make the idea of "ancient wall"
