Reducing Dust and Dirt

Spraying paint can be like a medical procedure where contaminants like dust and dirt can be costly. Below are some tips for keeping your paint environment and paint jobs clean so that your refinishing is more flawless. You may want to make a check list so that you give yourself every chance of generating clean paint work.

1. Gun cleaning is important. Be sure to clean your gun well right after you're finished using it, don't wait because waiting can cause paint materials to stick to the gun interior. A good gun spray gun cleaning kit is important for good goon maintance.

2. After cleaning your gun allow the gun parts to dry well before reassembly. Good paper towels are a must in many paint shops, we have four areas of a small shop that have paper towel dispensors.

3. Keep you paint bench clean. If the bench is in the room you should not allow dust or dirt to accumulate on the surface because it can cause your gun or paint materials to get contaminated. A smooth bench top that can be wiped periodically helps keep contaminates out of your paint work. Simply walking by a dust contaminated surface can launch dust in that air that turns into dust nibs on your painted vehicle.

4. Using metal or plastic paint sticks to stir your paint is much better than wooden sticks. Wooden sticks can pick up dust or dirt that can be transferred to your paint while plastic or metal sticks can be cleaned before stirring paint products. Save the wooden sticks for primers other other liquids that get sanded prior to coating.

5. Try to keep unnecessary parts and workbenches out of the painting area. Many horizontal surfaces will pick up dust that can be transferred to your work. Remember that walking past a work bench can cause dust to be launched into the air and land on wet paint. Even walls should be blown off prior to applying top coats.

6. Air hose tends to pick up dirt off the floor so wipe it off prior to using on important work. A damp cloth works well for this purpose.

7. Plan ahead... try to keep sanding to a minimum in the paint room as the time approaches for doing any important spraying.

You can also plan ahead by not attracting insects to the paint room for weeks prior to spraying. IE. Minimal outdoor lighting at night in some areas.

8. A vehicle running over your air hose can help it break down inside. This can cause particles to get blown into your work. Keep hoses out from under cars when the cars are being moved.

9. When the floor is damp it can release less dust into the air. If your air movement is minimal or moving so that it can carry particles into your fresh paint then you may want to consider dampening the floor. Spraying the floor with a little water can help the dust situation dramatically. Don't use too much water, you don't want to generate any splashing.

10. Keeping surface contamination in mind from the beginning will aid in a better end result. Washing and removing grease, wax, oil, etc. from the surface before and after sanding then proper blowing with compressed air then a final tacking using the proper tack cloth prior to spraying color can greatly improve the outcome.

11. Using your masking materials for both primer and color will almost certainly generate dust and particles in your top coats. It is usually recommended that the car be unmasked after the primer is sanded then washed, blown off, masked, solvent cleaned then tacked and painted.

12. Many contamanants come from two sources... the vehicle and the painter. We addressed the vehicle in previous post, the painter is just as important.

You should be wearing a clean paint suit like the Krew Suit linked below. Clothing is usually one of the biggest dust makers so a clean paint suit eliminates that variable. Blow off any hoods or face masks and wear a clean pair of protective gloves.
