Powertex Rusty Powder produces impressive rust effects. It can be mixed with light colored Powertex (preferably ivory or ivory mixed with another Powertex color) or Easy Structure, and applied with a spatula. For different effects and gradations, sprinkle the powder on the liquid paste. Powertex Rusty Powder is easy to use and can be combined with other media. To use Powertex Rusty Powder: Pour a little Powertex (preferably ivory or soft tones) in a bowl and add the Rusty Powder (10 - 25%).
The more powder used, the darker the result. Spray a mixture of water and up to 50% vinegar in the mixture. It can also be sprayed several times on the desired object to increase the rust effect. Allow to dry for 24 hours.
