I’ve always been fascinated with rust: the amazing texture, the beautiful contrast of colours (especially when it appears on bluish backgrounds), and the general atmosphere of historical mystery suggested by its presence.
Over the years, I have tried a few ways of imitating rust in my artwork and crafts (burnt sienna acrylics, grainy orange embossing powder, paint on glue, etc). Today, as promised, I will show you my favourite way of achieving authentic-looking “rust” very quickly and easily.
Choose the surface which you want to “rust”. I chose a metal key (similar to the one on this card) and a cogwheel. Now you will need some PVA glue, granulated coffee, and a heat tool. I would also recommend using a fixative or varnish of some sort, just to seal the finished result.
Step 1: Apply a layer of PVA to the surface of your charm.
Step 2: Sprinkle some granulated coffee on top. While doing this, break and powder the granules between your fingers. Don’t worry about any bigger pieces – non-homogeneous grains will help you achieve a more natural look. Gently remove the excess.
Step 3: Heat it up! Let the gluey coffee burn a little. But learn from my mistakes – transfer the charm to a cleaner surface before you use the heat tool, or you risk blowing the coffee powder everywhere (and I mean, everywhere).
Step 4: Gently remove or sand-down bigger bits of coffee.
Voila! Doesn’t it look authentic?! You can repeat the process again until you reach the desired effect. I went ahead and did that with the key.
The same technique can be used on paper/card.
Below you can see two different effects; the difference is the amount of glue. I applied much more glue to the left side, so there was much more of it to burn, creating bubbles and leaving a very interesting texture that you can often see on rusty metal.
At this point you might want to seal the result using a fixative/matte varnish, as both PVA and coffee are water-soluble.
