Using a paint sprayer can be a game-changer for your painting projects, offering a smooth finish in less time than traditional brush or roller methods. While it may seem hard at first, mastering this tool can significantly improve your DIY painting skills.
In the video above, Ask This Old House painter Mauro Henrique explores the ins and outs of using a paint sprayer. Plus, he shares his expert techniques for a flawless result.
Preparing Your Work Area Before Using a Paint Sprayer
Before you start spraying, prep your work area to avoid unnecessary messes or damage to your home. Here are some best practices to follow:
- Use plastic drop cloths: Cover floors, furniture, and any other surfaces you don’t want the paint to get on.
- Apply painter’s tape: Protect edges, trim, and any other areas that need safeguarding.
- Remove or cover hardware: Light fixtures, electrical outlets, and other hardware should be covered or removed.
Make sure you have proper ventilation in your work area. We recommend opening your windows and doors and using fans to circulate air and reduce paint fumes. Good ventilation makes your working environment more comfortable, but it also helps the paint dry faster.
Setting Up Your Paint Sprayer
Follow these steps to get your sprayer ready for action. In the video, Henrique uses a Titan Impact 640 Skid airless paint sprayer.
Priming the Sprayer
First, turn the valve on the side of the sprayer to “prime.” Place the painting tube into the paint can and set the clear priming tube in an empty bucket. Turn on the sprayer and wait until no more bubbles are coming out in the bucket.
Attaching the Spray Gun
To attach the spray gun, connect the spray hose to the machine and switch the side valve to “paint.” Spray paint into the priming bucket until no more water or bubbles come out. Then, attach the spray guard to the top of the nozzle.
Paint Sprayer Painting Techniques
Mastering the right techniques will help you achieve a professional-looking finish. In the video, Henrique shows the proper way to hold and move the spray gun for optimal results.
Proper Spraying Motion
Always keep the spray gun parallel to the surface you’re painting. Keep a consistent distance from the surface, typically about 12 inches. Henrique uses long, smooth strokes, overlapping each pass by approximately 50% to get even coverage.
You should start moving the gun before pulling the trigger and continue moving after releasing it. This technique helps prevent excess paint buildup and creates a smoother finish.
Adjusting Spray Patterns
Most spray guns allow you to adjust the spray pattern to suit different surfaces. Experiment with these patterns to find out what works best for your project:
- Horizontal pattern: For up-and-down strokes.
- Vertical pattern: For side-to-side strokes.
- Circular pattern: For detailed work.
You can adjust the spray patterns to handle a variety of painting tasks. From large, flat surfaces to detailed corners, the beauty of a paint sprayer is its flexibility. For example, you can use the horizontal pattern for painting walls and fences, while the circular pattern is perfect for small, intricate pieces of furniture.
Common Paint Sprayer Mistakes To Avoid
Even experienced painters can run into problems when using a sprayer. One common mistake is spraying too close to the surface, which can cause drips and runs. Moving the sprayer too slowly is another issue, as it can cause excessive paint buildup.
If you don’t overlap the spray patterns by about 50%, the paint coverage may be uneven. Lastly, while many airless sprayers can handle unthinned paint, you might benefit from thinning the paint to achieve a smoother finish.
Longevity and Performance Tips
For the most consistent results, regularly inspect the nozzles and filters for any blockages or wear and replace them as needed. You’ll also need to lubricate the pump packing following the manufacturer’s guidelines.
Safety Considerations
Safety should always be a priority when using a paint sprayer. Here’s what we recommend you do to protect yourself and the environment.
Personal Protective Equipment
Personal protective equipment (PPE) minimizes the risk of exposure to harmful chemicals and makes your working environment safe.
- Wear safety goggles to protect your eyes from paint mist.
- Use a respirator mask to avoid inhaling paint particles.
- Wear gloves to keep paint off your skin.
Environmental Precautions
There are also environmental safety considerations to keep in mind:
- Never point the spray gun at people or animals.
- Be mindful of wind direction when spraying outdoors to avoid overspray.
- Dispose of paint and cleaning materials properly. Follow local guidelines for proper disposal.
Safe Usage Tips
Adjust the sprayer’s pressure settings according to the manufacturer’s recommendations for the type of paint you are using. Always test the spray pattern on a piece of cardboard or scrap material before starting on your main surface to verify that the settings are correct.
