Keeping The Spray Gun Clean

The spray gun itself is vital to reducing overspray, as a technician cannot achieve the rightfinish if their spray gun is unclean. The spray nozzle can become clogged over time and cause an uneven coating. Weve all seen when a gun is spraying more on one side or the other. Its imperative to keep the gun and all air passages clean.

The hose can also become covered in overspray and those same hoses tend to break down over time. Remember to change your booth hoses once a year, and if you are using a fresh air system, be sure you have a non-wicking hose for your breathing airline.

Ironically, overspray can also build up on spray guns and therefore should be taken apart and have all parts regularly cleaned.

Handy Tips To Effectively Maintain Your Spray Booth

When you get a breakdown, 80% of your business grinds to a halt, whereas a quick weekly check of your booth can prevent over 80% of such issues arising.

  • KEEP IT CLEAN keep the walls clean, tidy and dust free. Keep the floor clean to stop overspray and undesirable particles from entering your fresh paintwork, therefore reducing reworks. Keep your light protectors clean so your booth always has maximum light lux levels. If its dark and dirty you can make mistakes and not notice until you get outside in the natural light.
  • CHANGE FILTERS REGULARLY this keeps airflow within the spray booth at its correct designed levels. When this starts to drop, overspray starts to fly around, dust accumulates on the walls and flooring. Poor airflow also means fog takes longer to clear meaning the job stays in the booth longer. If the filters are blocked, the booth takes longer to get to temperature and may even struggle to get to temperature, which means longer bake cycles and softer paint which Im sure you are fully aware is going to hurt production time and end product quality.
  • ENSURE DOOR SEALS ARE CLEAN AND SEALED TO PREVENT CONTAMINATION its amazing how much dust builds up on doors, this is so often overlooked and causes contamination in your fresh paint work. Outside undesirables like Silicon can easily find their way into your, just a quick wipe of the door seals is highly worth your effort.
  • If this area is accessible keep it tidy for a happy and healthy spray booth!

    Improper Maintenance Of Spray Guns

    After every colour or product change, we would recommend you clean your spray booth guns in a specialist paint mixing or gun cleaning room. Its also important to thoroughly clean your spray booth guns with a high-quality gun cleaner. This will ensure any remaining paint is removed before the next job.

    What Are The Best Spraying Techniques

    Every technician should know and follow these best spraying techniques to help reduce overspray. Of course, we all know that application between some paint lines varies greatly but sticking to your products application method from training needs to be followed. Before spraying, make sure the spray gun is at the optimal distance away from the surface being painted, which, depending on the gun and whether youre spraying water or solvent, can vary from 6-10″.

    Also, the spray gun tip should remain perpendicular to the surface at all times. Anything at the wrong angle can result in more overspray than wanted outward of the panel and darker areas where the nozzle is closer to the panel due to the tilt. Correcting this by itself can help save haloing in blends. Its common for many newer painters to have issues in their blends due to application problems. Improper blending with the gun and blends being dry causes poor repairs and costly redoes.

    Andreae Filters Loadfrom Back To Fronteliminating Theface

    Easy Mobile Jobsite SPRAY BOOTH?

    The working principle of an Andreae Filter is such that particulates are captured by impaction on the face of the filter, then pulled through the openings and impacted again on the back wall of the filter, then pulled through the baffle to impact again on the back of the front wall and ultimately collect in the deep holding pockets out of the air stream.

    Because of the accordion shape and evenly spaced holes, the airflow isevenly distributed over the whole extraction surface of the booth, the static pressure remains low and the airflow stays constant during the loading phase.

    Other synthetic layers filters must be replaced regularly to ensure efficient operations. Clogged filters redirect air to a different path of least resistance, which will effect uniform airflow in the booth. Furthermore, this higher static causes the exhaust fan to reduce the amount of air exhausted

    Polyester Exhaust Filter

    Andreae Filters have 3-5x greater holding capacity than fibrous and mesh filters, resulting in longer service life, reduced waste and less down time during change outs.

    Fibrous and mesh filters tend to face load . The face-loading effect causes uneven airflow to occur at various places along the exhaust wall. As a result, filter life is greatly reduced.

    Problem 2 Neighbors Are Complaining About Odor

    Odor is a natural byproduct of painting, especially when using solvent-based coatings. However paint booths should typically exhaust any odor high enough into the air stream to prevent issues with neighboring facilities or residents complaining about smell. If there are complaints about the smell associated with your paint booth you should consider and evaluate the following.

  • Your paint booth fans operation-as mentioned above you should check the speed which are paper fan is exhausting air from your facility. If it is not up to the recommended speed based on your booth size, you may need to consider servicing or replacing your booth fan.
  • Filter upgrades-sometimes a coating that your spraying has such significant odor that you may need to consider a filter improvement like a charcoal backed paint booth filter. Charcoal backed filters will not last as long as traditional paint booth filters and will typically be a higher cost however they will reduce odors that may be being exhausted from your booth.
  • The height of your exhaust stack you can also consider extending your exhaust stack higher into the air stream so that odor is carried away more efficiently
  • The coating type you are using you can also consider evaluating alternative coatings for your particular application or using add-ins to your coatings to help mask any unpleasant odor this will be something you would have to check with your coatings provider to determine any potential solutions that may be available.
  • Air Flow And Static Pressure

    Managing airflow in a spray booth is not only critical in reducing combustible vapors but essential in maximizing coating delivery while directing overspray to the exhaust bank.

    A spray booth requires a minimum velocity to carry overspray to the exhaust bank. The velocity possible to achieve is determined by the fan size. Draft requirements must factor in airflow losses from openings, filters and ductwork.

    Static Pressure is defined as pressure exerted by liquid or gas when bodies on which the pressure is exerted are not in motion.9 Airflow within a booth must overcome resistance from ductwork and filters when moving from one point to another. As filters capture particulate matter, airflow decreases causing static pressure to increase. It is recommended that exhaust filters be changed when the pressure drops 0.5 in wc. However, Andreae Filters can withstand a pressure drop up to 1.03 in wc.
