Spray Gun Guide

Choosing the right spray gun is the foundation of a successful paint job

What spray guns are there?

Automotive spray guns are divided into three main types. The choice depends on experience level, budget, and compressor.

(High Volume Low Pressure)

Best choice for beginners and hobbyists. High transfer efficiency (~65%), less overspray waste. Requires larger compressor (250+ l/min).

Nozzle 1.3-1.4mm for basecoat, 1.5-1.8mm for primer and clearcoat

Pressure 1.5-2.5 bar at the nozzle

Beginners and hobbyists

(Low Volume Low Pressure)

Professional results with lower air pressure. Excellent surface texture control. Works with smaller compressors (200+ l/min).

Nozzle 1.3-1.4mm for basecoat, 1.5-1.7mm for primer

Pressure 0.7-1.5 bar at the nozzle

Advanced hobbyists and professionals

(Conventional / High Pressure)

Older technology, high pressure. Fast but high waste (~35% material lost). Rarely recommended today.

Nozzle 1.4-1.8mm

Pressure 3-4 bar

Professionals in large spaces

1.0-1.2mmTouch-up paint, thin materials

1.3-1.4mmBasecoat (WBC/metallic), clearcoat

1.5-1.7mmPrimer, filler, thicker materials

1.8-2.0mmHigh-build primer, epoxy, thick materials

Start with an HVLP gun – forgives mistakes

ALWAYS practice on cardboard or scrap first

Keep a steady 15-25cm distance from the surface

Move at a consistent speed – don't stop mid-stroke

Clean the gun IMMEDIATELY after use with thinner
