A spray booth is one of the biggest capital investments that your business will make. It allows you to produce high-quality finishes and provides safer working conditions. For these reasons, a spray paint booth maintenance programme should be firmly embedded in your routine operations. A booth that runs at optimum efficiency will keep production costs down and supports health and safety compliance.
The cost of improper maintenance for your bottom line
Improper booth care can drastically affect your productivity and plant maintenance costs. The spray booth is more likely to break down, resulting in costly downtime and repair bills. Dust and debris will reduce your finish quality and increase the need for reworks.
The cost of improper maintenance for worker health and safety (and your bottom line)
In the UK, exposure to isocynate is the single biggest cause of occupational asthma. This is a particular concern in workshops that use paints and lacquers containing isocyanate hardener.
A booth’s extractors and filters play a critical role in reducing exposure to contaminants and harmful fumes, like isocyanates. If the booth is not properly maintained, its filters and extractors will be less effective.
This can result in:
·Increased worker sickness absence, litigation and associated costs
·Low workforce morale
·Potential increase in insurance premiums
Spray booth maintenance tips
These best practice tips will help you to keep your booth in top condition and your painters safe.
1. Reduce contamination
When contaminants find their way into your booth, they clog filters and affect finish quality. Taking the following steps will reduce the amount of dust and dirt entering your booth from the workshop floor:
2. Change filters regularly
Good filtering is essential for effective ventilation and removal of contaminants. For a booth that is used daily, we recommend changing your filters every three weeks. Make sure you know where all the filters are in your booth and continually monitor and replace them as necessary. Always use high-quality filters.
3. Conduct routine checks
Schedule the following daily, weekly and monthly checks into your maintenance programme:
· Booth pressure
· Signs of damage to the ducting, fan and filters

For windows and lights:
Peelable booth coatings – liquid or spray-on treatments that dry to a protective film. Once soiled, peel them off according to the manufacturer’s instructions and recoat.
Self-adhering film – easy to fit and remove and available in a range of lengths and widths to meet your needs.
Matting – durable, padded matting that can be vacuumed daily to remove contaminants.
Spray-on floor coating – a daily floor treatment that traps contaminants. It neutralises the electrical charge of air particles so that up to 50% of contaminants fall to the floor instead of sticking to your workpiece.
5. Have a deep clean protocol
Your schedule should include regularly cleaning your booth using the following protocol:
6. Measure spray booth clearance times
It can take 20 minutes or more for isocyanates to fully clear from the booth after spraying. To maintain safe working practices, the HSE recommends that you do the following:
7. Take extra precautions with water spray booths
Water wash paint booths pose additional health hazards if the water isn’t treated routinely. A build-up of paint sludge creates an ideal environment for bacterial and fungal growth. This can cause Legionnaires’ disease and biological odours.
8. Test and maintain RPE
Paint booth maintenance also extends to looking after respiratory protection equipment.

9. Adhere to the manufacturer’s maintenance schedule
Your maintenance programme should follow the maintenance schedule provided by the booth manufacturer. The schedule should include guidance on how often to inspect, clean and replace key components of your booth, such as filters.
10. Build a responsible team
A spray paint booth maintenance programme needs someone to oversee and manage it. It also needs a team of trained painters who understand their maintenance responsibilities.
