Keeping your spray foam equipment in top shape is key to performance and jobsite success. The Graco Fusion PC spray gun is a contractor favorite thanks to its quick-change ProConnect cartridge, but like all spray equipment, it requires consistent care. In this blog, you’ll find pro tips to help extend the life of your Fusion PC, prevent downtime, and maintain spray quality.
Daily Cleaning for Maximum Performance
The Fusion PC gun is designed to reduce rebuild time, but it still depends on daily maintenance. At the end of each spray session:
- Wipe down the gun with a soft cloth to remove overspray.
- Purge any remaining material from the gun body.
- Inspect the ProConnect cartridge for residue and clean with approved solvents.
These small steps prevent hardened foam from clogging passages and keep your spray foam equipment running smoothly.
Cartridge Care and Replacement
One of the biggest advantages of the Fusion PC is its disposable cartridge system. Instead of spending hours on a rebuild, you simply replace the cartridge. To get the most out of each cartridge:
- Avoid over-tightening when installing, as it can damage seals.
- Keep spare cartridges stored in a clean, dry space.
- Replace cartridges at the first sign of uneven spray or increased trigger resistance.
This not only saves time but also ensures your jobs stay on-ratio and consistent.
Spray Pattern and Performance Checks
A well-maintained gun delivers a clean, even spray pattern. To ensure your Fusion PC is performing at its best:
- Test spray onto a piece of cardboard before each job.
- Look for smooth, balanced coverage with no streaks or sputtering.
- If the spray pattern is irregular, check for worn mix chambers or dirty cartridges.
By catching small issues early, you’ll save yourself from bigger repairs later.
Safety and Storage Best Practices
Good maintenance goes hand in hand with safety. When working with spray foam equipment:
- Always depressurize before cleaning or part replacement.
- Wear proper PPE including gloves, eye protection, and respirators.
- Store your Fusion PC in a protective case to shield it from dust and accidental damage.
