What to Know About Spray Finishing Tools
Spray finishing tools include HVLP turbines, conversion guns, detail guns, air compressors, cups, strainers, filters, spray shelters, exhaust systems, and personal protection. The system must match the finish viscosity and the shop environment.
Working principleAir pressure or turbine airflow breaks liquid finish into droplets and carries it to the surface. Tip size, fan pattern, flow, distance, overlap, and ventilation determine the final film.
Common Woodworking Uses
- Spraying clear coats on cabinets and furniture.
- Finishing chairs, turnings, and shaped parts with complex surfaces.
- Applying paint or pigmented finishes evenly.
- Touching up repairs and small parts.
- Building thin repeatable coats with controlled overlap.
Choosing Spray Finishing Tools
- Check finish viscosity and tip size before buying a gun.
- Use HVLP turbines when a large compressor is not available.
- Use compressor systems only with clean dry air and enough air volume.
- Plan ventilation and personal protection before spraying indoors.
Setup
- Strain finish into the cup.
- Test fan pattern and flow on cardboard or scrap.
- Keep gun distance and overlap consistent across each pass.
- Mask nearby surfaces and plan where overspray will go.
- Set regulators and filters so compressor air stays clean and stable.
