Since this is a quick job, a freebie, and I can't spend much time on it, we will be doing this as quickly and inexpensively as possible.
Materials included 2 8ft. pieces of Blue insulating foam board, a pint of Sienna latex enamel, a quart of yellow almond latex enamel, sponge brushes, paint roller and pan, sharpie magic markers (black), 2 0z. Black acrylic airbrush paint, 2 0z. white acrylic airbrush paint.
Step one- Make sure that your boards are to size and ready to be painted.
Step two- Cover each board with the yellow/almond acrylic paint with the roller. Perfect coverage is not essential, just get rid of the blue.
Step three- Using the sponge brush, apply the sienna acrylic. The acrylic straight out of the can will be too thick to lay down convincing woodtones. Add a bit of water to the sienna until it is thinner but not soupy.
Lay down the woodtone in long strokes. The thinned paint will allow the sponge brush to leave streaks that imitate the wood grain. It is very quick and easy, but impressive.
Step Four- Using a t-square and your sharpie, draw the lines that separate the wood panels.
Step 5 - Use the sharpie to draw out your iron hardware. Fill these in with the black acrylic airbrush paint.
Step 6 - Finally, add highlights to the iron hardware and bolts.
Done! If you wanted to get even more detailed that this, (I didn't) You can add a but of shadowing under the door ring handle with your airbrush and some black acrylic. For the purposes of this project, this was all I needed.
