Learn to Brush Paint Model Airplanes – Andy M, 19 Pages
- A guide to getting a great model airplane paint job with a brush. Remember that you will spend hours (maybe tens of hours, or in some cases hundreds of hours!) getting your model airplane to the stage where it is ready for painting. You will more than likely invest additional hours in painting several layers before the model is done. One mistake due to lack of preparation or not recognizing a potential problem could leave you frustrated.Why settle for a poor paint job, or risk having to spend more time taking paint off your model…? We’ve already made just about every mistake possible with an paintbrush, so let our experience be your guide!
- Every paint has three main components: the pigment which is the color containing part, the resin which binds the pigment to the surface, and the solvent which holds everything together in the liquid form. There are two broad classes of paint, enamels and lacquers. Enamels undergo a chemical reaction (curing) as the solvent evaporates. In lacquers, the solvent evaporates without any curing. Now hobby paints are generally (oil-based) enamels, or aqueous (water-based) acrylic lacquers. The hobby enamels (e.g. Testors, Model Masters, Humbrol) thin with mineral spirits, dry slowly and harden beautifully to a glossy finish. The hobby acrylics (e.g. Tamiya, PollyScale, Floquil, Vallejo) thin with water or alcohol, dry faster, and clean up easier. People tend to develop a preference for one or the other, so try both and see which you prefer.
- Another good solvent to know about is Future Floor Wax. Yes, Floor Wax. It’s a liquid acrylic designed for floors. It works great as a gloss coat, and can be brushed straight from the bottle without thinning.
- The paintbrush is the simplest method of applying paint. They come in different shapes, flat and round being the most common. They also come in different sizes and materials. You'll need at least: a broad flat brush for large area coverage (1/4 inch or larger), a medium width round brush for general use (#1 or 2), and a finepoint brush for detail work (10/0).
- Having a convenient work area for painting will make your like much simpler. It’s best to use a sturdy workbench or table. Something that can be accidentally collapsed by a pet or child will not do. Make sure you have adequate ventilation in the room, especially if using enamel paints. Open a window and use a fan to help move air through the room. One convenient accessory is a turntable for crafts, available from Target or others. It’s basically a round stand that can rotate on its base. The one in the photo below is glued to a cheap stool for outdoor work, but you could just as easily place it on your worktable. This is convenient for painting with one hand while rotating the table with the other, so that all sides of the part get painted. I also have all the “bits” needed for painting in a plastic box “caddy” beneath the turntable. That way I can get all the necessary stuff to my paint area without making a large number of trips back and forth.
