With Rusting Powder you can very quickly achieve a rusty look on most surfaces including wood, over paint, on paper, fabric, etc. We find natural surfaces work the best as they are porous fibres. Sprinkle some rusting powder on your surface and gently mist with water, lemon juice or white vinegar.
1. Adhere the powder to any surface by sprinkling into a wet glue liberally. Allow to dry
(NB do not embed powder in the glue, the powder needs to be exposed in order to rust)
2. Spritz with water, and keep damp by spritzing regularly (hourly) for 3-4 hours or until the rusty colour you like is achieved (orange through to deep brown).
(NB to speed up this process, add some acid, such as lemon juice or vinegar to the water)
