Choosing the correct fluid tip (nozzle) size is crucial to achieving a flawless finish. Whether you're applying basecoat or clearcoat, selecting the right size ensures proper atomization, flow, and consistency - especially in forge refinished painting workflows with an LVLP spray gun.
The nozzle controls how much paint flows through the gun. Too small = dry spray. Too large = runs. With LVLP spray guns, proper size ensures efficient use of low air volume.
| Application | Nozzle Size | Notes |
|---|---|---|
| Basecoat (solid/metallic) | 1.2–1.3mm | Thin material, easy atomization |
| Clearcoat | 1.4–1.5mm | Slightly thicker, needs flow |
| Primer | 1.7–2.0mm | Heavier material, not for LVLP use |
Waterborne basecoats: 1.2–1.3mm for fine misting
High-solid clears: 1.4–1.5mm for smooth leveling
Low-viscosity single-stage: 1.3mm ideal
If you're seeing:
Dry edge fade → nozzle may be too small
Heavy center or runs → nozzle too large or spraying too close
Because forge refinished painting focuses on controlled layering, a slightly smaller tip (1.3mm) offers better atomization and paint control for car painting, especially for DIYers or shops using compact compressors.
