How to maintain your spray booth
Regular spray booth maintenance is essential if you want to keep your workspace safe, efficient, and compliant. Whether you're running a small unit or a large-scale facility, maintaining your spray booth properly ensures high-quality finishes, reduces downtime, and extends the life of your equipment. In this guide, we’ll break down the basics of maintaining a spray booth, including daily tasks, scheduled servicing, and what to watch out for.
Why spray booth maintenance matters
Spray booths play a critical role in delivering clean, controlled environments for surface coating tasks. But without proper care, overspray, dust, and solvent fumes can build up quickly, affecting product quality, operator safety, and compliance with health and safety regulations.
Maintaining your spray booth helps:
- Ensure consistent spray results
- Protect operators from harmful particles and fumes
- Prevent fire hazards
- Minimise costly repairs and breakdowns
- Extend the lifespan of your equipment
Common issues poor maintenance can cause
Neglecting spray booth maintenance doesn’t just reduce efficiency – it can lead to bigger problems that affect your output, costs, and safety. Here are some common issues to watch out for:
- Uneven finishes: Poor airflow or blocked filters can lead to inconsistent coatings, which may require rework or touch-ups.
- Increased downtime: Unexpected breakdowns or worn-out parts can bring operations to a halt, leading to delays and missed deadlines.
- Health and safety risks: A build-up of fumes or overspray increases exposure to harmful substances and can create fire hazards.
- Higher running costs: Clogged filters and faulty components force your system to work harder, using more energy and wearing out faster.
- Compliance failures: Failure to maintain key components like fire suppression systems or ventilation can put you at risk of breaching HSE regulations.
Spotting these issues early – and preventing them with regular maintenance – keeps your booth performing safely and reliably.
Spray booth maintenance checklist
Small, consistent tasks can prevent major issues down the line. Use this checklist to maintain your spray booth’s performance, safety, and efficiency.
- Clean booth surfaces: Wipe down interior walls, floors, and doors to remove overspray and dust. Use appropriate cleaning products to prevent damage to internal surfaces or filters.
- Check airflow and pressure gauges: Monitor pressure readings and investigate any fluctuations, which may indicate clogged filters, fan issues, or mechanical faults.
- Inspect and clean pre-filters: These capture larger particles before they reach exhaust filters. Clean or replace as needed to maintain consistent airflow.
- Replace intake and exhaust filters: Follow a maintenance schedule based on filter type and booth usage. High-throughput operations may require more frequent changes.
- Inspect lighting and seals: Ensure lighting is clean and fully operational for accurate coating. Check door seals for wear to maintain a clean, controlled environment and prevent particulate ingress.
- Check for paint build-up: Clean hard-to-reach areas such as corners, grilles, and beneath equipment to avoid hardened deposits that affect booth performance.
- Service fan motors and belts: Inspect belts and motor components for wear. Lubricate or replace as necessary to ensure reliable airflow and avoid system strain.
- Review your maintenance log: Maintain a detailed record of checks and repairs. This helps identify recurring issues and provides valuable documentation for audits and inspections.
- Train your team: Ensure operators understand how to use the booth safely and perform essential maintenance tasks. Airblast Eurospray offers comprehensive training to support confident, competent operation.
- Stock essential replacements: Keep spare filters and other consumables on hand to minimise downtime during maintenance.
- Book periodic professional servicing: In addition to in-house maintenance, schedule inspections by qualified engineers to verify booth performance and safety. Airblast Eurospray offers expert servicing – from routine checks to full system overhauls – to keep your operations compliant, efficient, and productive. For users to ensure legislative compliance, they must conduct a statutory LEV test with a qualified specialist.
Final thoughts
Spray booth maintenance doesn’t need to be complex – it just needs to be consistent. By building checks into your regular workflow and staying on top of servicing, your booth will continue to deliver safe, high-quality results day after day. And when in doubt, always refer to your equipment manual or consult with a trusted expert.
