Spray gun types explained: Which one is right for your job?
Choosing the right spray equipment is essential for achieving a high-quality finish, working efficiently, and minimising waste. But with a wide range of spray gun types on the market, it can be difficult to know where to start.
Whether you're tackling protective coatings on structural steel, refinishing woodwork, or working in a precision paint shop, the right system makes a big difference to the outcome.
In this blog, we explain the main types of spray guns, their key features, and how to choose the most suitable option for your task.
Conventional spray guns
Overview: Conventional spray guns use compressed air at high pressure to atomise coatings. They’re one of the oldest spray technologies and still widely used for their ability to produce fine finishes.
Best for:
- Automotive finishing
- Woodworking and cabinetry
- Furniture painting
Pros:
- Fine atomisation for smooth, even finishes
- Compatible with most types of coatings
Cons:
- High overspray and paint waste
- Lower transfer efficiency compared to newer systems
Tip: Best used in well-ventilated spaces with effective extraction due to higher levels of airborne particles.
HVLP (high volume low pressure) spray guns
Overview: HVLP systems use a high volume of air at low pressure, resulting in a softer spray. This reduces overspray and increases transfer efficiency, making them a popular choice in controlled environments.
Best for:
- Indoor use
- Water-based paints and lacquers
- Precision work and fine finishes
- Smaller-scale projects
Pros:
- Reduced overspray and material loss
- Cleaner work environment
- Excellent for detailed, controlled finishes
- Typically more affordable than airless systems
Cons:
- Slower application speeds
- Requires an air compressor
- Limited paint capacity due to smaller onboard reservoirs, frequent refilling needed
HVLP systems are ideal for detail-focused applications where control and reduced emissions are priorities.
Airless spray guns
Overview: Airless spray guns work by pumping paint at very high pressure through a small orifice, atomising the coating without using compressed air. They’re ideal for fast, even coverage over large surfaces.
Best for:
- Handling heavier materials (tip-size and air cap dependent)
- Steelwork and structural components
- Exterior and industrial maintenance
Pros:
- Fast, efficient application
- Handles high-viscosity coatings
- Great coverage on uneven or textured surfaces
Cons:
- Limited control over spray pattern
- Potential risk of overspray and bounce-back
- Requires proper training for safe use
Airless systems are especially effective when speed and coating thickness are key factors.
Air-assisted airless spray guns
Overview: This hybrid system combines airless spraying with a small amount of air to improve atomisation. It delivers a balance between speed and finish quality and is commonly used in high-production environments.
Best for:
- Industrial production lines
- Metal fabrication
- Consistent finish across complex shapes
Pros:
- High-quality finish at faster speeds
- Better control than standard airless systems
- Good for uniform film builds
Cons:
- More expensive and complex to set up
- Requires trained operators for best results
Ideal when you need both productivity and finish quality in demanding environments.
LVLP (low volume low pressure) spray guns
Overview: LVLP systems use lower air volume than HVLP guns, making them suitable for workshops with limited compressor capacity.
Best for:
- Fine detail work
- Smaller jobs or occasional use
Pros:
- Economical with air usage
- Smooth, precise finishes
- Lower overspray than conventional guns
Cons:
- Slower output
- Will struggle with heavier materials
How to choose the right spray gun
| Factor | Considerations |
| Surface size | Larger areas benefit from airless or air-assisted airless guns |
| Finish quality | HVLP and air-assisted airless offer greater control for fine finishes |
| Coating material | Thicker materials work best with airless or air-assisted options |
| Work environment | HVLP and LVLP are ideal for enclosed or well-ventilated indoor settings and less demanding production requirements. |
| Compressor capacity | Ensure your compressor matches the air requirements of your chosen spray gun |
