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.

Please note: when you place objects outside the surface can continue to rust.

Painting with Rusty Powder

There are many ways to use the Rusty Powder in your artwork… you can try the following:

  1. Pour Powertex directly onto the canvas and mix the Rusty Powder in with palette knife and spread.
  2. Make a paste with Powertex as described above with 3D Sand, Rust Powder, a dash of vinegar and a dash of water and apply it with a palette knife.
  3. Use Powertex Easy Structure mixed with Powertex and some Rust Powder. Sprinkle some extra powder where a darker effect is desired and press in.
  4. Add 3DSand and Balls for textural effect (ensure there is enough Powertex for them to adhere)

 

When you have added the Rusty Powder to your artwork:

  • Spray the canvas with a Vinegar/water mix (max. 50% vinegar). Repeat a number of times, there should be a pool of water on it. Let it dry for at least 24 hours.
  • Once oxidation is complete rusting will stop.
  • If desired you can dry brush your artwork with contrasting Powercolour or Colourtrix pigments e.g. Light Blue, Turquoise and Titanium White.
