Vacuum Coating vs Spray Finishing for Timber Profiles
Two methods, fundamentally different approaches. Which one makes sense for your production?
Two Approaches to the Same Problem
Spray finishing projects coating onto the workpiece surface. It's versatile and well-understood, but inherently wasteful — a significant proportion of the coating never reaches the timber. Vacuum coating, by contrast, immerses the workpiece in coating material, achieving near-total transfer efficiency.
Both methods have their place, but for high-volume timber profile priming, the economics strongly favour vacuum coating.
Method Comparison
| Aspect | Spray Finishing | Vacuum Coating |
|---|---|---|
| Transfer Efficiency | 30–60% | ~100% |
| Overspray | Significant — requires extraction | None |
| 4-Side Coverage | Requires multiple passes | Single pass |
| Floor Space | Large (booth + extraction) | Compact inline unit |
| Environmental Impact | VOC extraction needed | Minimal — closed system |
| Complex Profiles | Shadowing on detail | Full contact coverage |
For linear timber profiles, vacuum coating is more efficient, more compact, and produces less waste than spray finishing.
