A paint spray booth is likely one of the biggest investments a garage or body shop can make and, with proper maintenance, it’s certainly worthwhile. While you can paint vehicles without a spray booth, doing so will often result in an inferior final result and can also be hazardous to your staff and to the environment.
It’s important to make sure your spray booth gets the necessary maintenance to keep it running as smoothly as possible – not doing so can result in costly repairs, hazardous working conditions, and poor quality paintwork. The Haltec team are here with some of their top tips for proper spray booth maintenance, so you can keep yours in tip top condition.
Conduct regular routine checks
Regular checks will help you get to know your equipment and identify any issues early on. We recommend scheduling daily checks for things like booth pressure and signs of damage to the booth and its door seals. Weekly inspections should be carried out for making sure there’s no damage to the ducting, fan and filters, and for checking the pressure gauges. Testing for leaks from the booth and ducting should be done monthly using a smoke generator.
Dust and other contaminants can easily find their way into a spray booth if overlooked, which can clog your filters and contaminate your fresh paint work. We suggest regularly wiping down the booth door and seals, as this will remove undesirable materials like dust and silicon.
Other steps you can take to reduce contamination include:
- Turn the booth on when bringing vehicles, parts, and tools into the booth.
- Keep doors shut at all times, apart from when bringing in vehicles or parts.
- Don’t sand inside the booth.
- Blow off and tack vehicles, air hose, and other parts before bringing them into the booth.
- Limit traffic in and out of the booth when spraying.
Change filters regularly
One of the most crucial maintenance tasks is to check and change your filters regularly, as this keeps airflow at the correct level. If airflow is not correct, overspray occurs, dust accumulates, and fog takes longer to clear. If your filters become clogged, the booth takes longer to reach the desired temperature – if it reaches it at all – which means longer production times and softer paint.
If your booth is used daily, we recommend changing your filters every three weeks. Make sure you’re aware of the location of all filters and check them regularly, so you can pick up on and rectify any problems early on.
Put a service plan in place
Your spray booth should be serviced at least every 14 months. This can involve fan cleaning; burner removal, cleaning, and setup; and overspray removal from internal ductwork and machinery area.
You should also carry out an annual smoke test. This ensures that the booth continues to eliminate contaminants, and knowing your equipment’s clearance time means you can take further precautions such as advising your team not to remove respiratory protection equipment within that time-frame.
You should always adhere to your spray booth manufacturer’s maintenance schedule and guidance. If you’d like some expert advice on keeping your spray booth in tip top condition, Haltec is here to help. Get in touch today for more information.
