How to use Rusty Powder
Rusty powder works best with a light coloured Powertex such as Ivory, Yellow Ochre, Terracotta or Red. Alternatively you can add Ivory Powertex to any Powertex colour to make a lighter colour.
- Apply one layer of Powertex onto your object and leave to dry.
- Make a smooth paste in a cup with Powertex + 3D Sand. Add approximately 25% Rust powder until it is a mouse-gray colour. Add a dash of vinegar and water and mix again.
- Apply a layer of this paste with a brush or palette knife onto your artwork. For different shades and effects sprinkle a little bit of the powder on the wet paste and press in. The more Rust Powder added the darker the result, the more vinegar the darker the result.
- Fill a spray bottle with water and max 50% vinegar and spray over the object a few times. (More vinegar gives faster and darker rust effect). You can add in layers, one on top of the other.
