Spray Painting Techniques

By Al Mu

If you are new to spray painting, these following techniques will help you to get a professional look and finish to each and every project that you start. Here are some of those techniques. They are not listed in any particular order. Use this paint in a well ventilated room and protect your project from overspray with drop cloths. Prepare your project for painting, by having a clean, dry surface to start with. If you are working with wood, sand the surface smooth before painting. When working with metal remove loose rust and grease before spraying.

When working with glass, plastic or ceramic, first sand with very fine grit sandpaper and wipe clean before spraying. Always use primer on bare wood and metal. Shake the can for a full two minutes before spraying. Spray 10Ē to 12Ē in a back and forth manner to completely coat. Have several coats so that the project is completely covered. Allow paint to dry before putting on a second coat of paint. When painting, always wear protective gear, such as a face mask to protect yourself from breathing in the fine mist particles and making yourself sick.

Now letís look at airless spray painting techniques. When using an airless sprayer, be certain to mask off everything that you donít want covered by paint. Make sure that you have plenty of ventilation. Hold the sprayer a consistent 6 to 12 inches from the surface and make runs in 3 foot sections. After finishing the 3 foot strip finger off the trigger at that end then position for another sweep. Make sure safety is one when not painting. Only work in a well ventilated area. Never allow the sprayer to be pointed at a person. Be certain that the paint has been thinned properly.

Now letís take a brief look at some techniques for auto painting. Bear in mind that all surfaces must be clean before painting can begin. Always use protective clothing when auto spraying. Depending upon the type of paint that you are spraying, the directions are to start from about 8 to 10 inches for enamels, and lacquers are 6 to 8 inches. Urethanes are also 8 to 10 inches. Use even strokes and overlap by at least 50% in order to fully cover the automobile. At the end of each stroke, fingers off the trigger. The ideal temperature for painting autos is at least 70 degrees.

Our final area of discussion is in painting R/C Cars. You have two different options when using spray paint. You have cans and airbrush. Both have similar techniques; however the airbrush does offer you more paint selections than does a regular can of spray paint. Remember when using different paints such as lacquers and acrylics, bear in mind that when using a machine, the psi needs to be set to15 to 25 psi for lacquer and acrylics between 25 and 80 psi. Painting is done by level strokes on the body and a gentle overlap is also needed. These are just some of the painting techniques that can be used.
