Things You'll Need
Compressed air source
A custom airbrushed painting on leather makes for an impressive piece of art or clothing. Before you start your project, be aware that there are distinctive qualities to painting on leather. A leather surface is more textured and less absorbent than cotton or other textiles typically used for airbrush art. This can sometimes cause unwanted paint buildup. On the other hand, since the paint doesn't soak in, a sharper, more detailed image can be rendered. It's also possible to use paintbrushes and other tools that are impractical for a T-shirt artist. Plus, if you make a mistake you might be able to wipe off the wet paint.
How To Airbrush Leather
Clean the leather surface, and remove any oil or leather protectants with a grease remover. Mount the leather on a board. If necessary, use spring clamps to stretch the material, so the work surface is flat and smooth with as few wrinkles as possible.
Set up a work space with a spray booth in a well- ventilated area. Connect the airbrush to the air source, and put on a face mask.
If you have a prepared design, use a projector to transfer the image to the surface. Sketch the design in pencil. When working on black leather, use a white pencil. Alternatively, you can paint a light, misty, white base coat and when the paint is dry, sketch the design with a graphite pencil. Apply any masking required by the design.
Select a color of textile paint, and load it into the airbrush paint cup. Start filling in the design with paint. Change colors, and adjust the masking as necessary to finish the picture.
When the painting is done and thoroughly dry, heat-set the design. You can use a heat press, a hot air gun for five minutes at high heat or a clothes iron with a protective cloth for 30 minutes at medium heat.
If properly heat-set, the painting should not need a clear-coat finish.
Try to avoid excessively layered painting techniques that cause the paint to build up on the surface.
