Powder coating is the process of applying a dry powder, as opposed to liquid paint, as a colored coating onto a surface. Powder coats last longer than wet paint and allow for special effects such as varying textures and candy colors. If the idea has piqued your do-it-yourself instincts, read up on the dos and don’ts, grab a powder coating machine, and get started!
Do:
- Buy the right powder coating machine. Whether you’re just powder coating at home or using the machine for a larger project, there are many affordable choices for you.
- Buy the right powder coating. Make sure to pay attention not only to the affordability of the coating but also to the coating’s UV resistance, particle size, and durability.
- Pre-heat materials such as plastic, wood, glass, or metal in your oven up to 400 degrees Fahrenheit, as recommended by Powder Coat Guide. Skipping this step will cause the powder to simply fall off. This process is otherwise known as ‘curing.’
- Paint in multiple coats. According to Rod Authority, two passes is the absolute minimum for coating.
- Paint in a dry and cool environment. If it’s too hot, the powder may cake.
- Wear a dust mask to protect your lungs. Work in a well-ventilated area.
Don’t:
- Put on too much powder coating. A too-thick coating can result in the powder running like paint.
- Over-cure your materials. Over-cured materials may become discolored and otherwise unsalvageable.
- Cross-contaminate your spray gun with colors. Some colors may be incompatible with each other. Use this opportunity to clean out the entire gun itself.
- Light a flame around fine powder as it is floating in the air. The powder is flammable and can explode.
- Touch the emitter to the spray gun. You’ll get electrocuted.
After reading up on these basics and doing your research on colors, machines, and materials, you’ll be all set to do some coloring. Have fun and get creative!
