- Clean screens in the gun-wash solvent immediately after spraying.
- Match screen mesh to tip size — a finer screen than the tip needs only clogs faster.
Common Selection Mistakes with Paint Strainer & Spray Gun Filter Screen
- Using a fine gun filter for high-build primer, which starves the gun.
- Leaving paint to dry in the screen.
Where Paint Strainer & Spray Gun Filter Screen Is Not the Right Choice
