• Workshop spray jobs
• Primer application
• Clear-coat application

Do not overfill the cup. Leave sufficient space for secure lid fitting and paint movement.

Standard 1.5mm Nozzle

The spray gun is supplied with a standard 1.5mm nozzle.

A 1.5mm nozzle is commonly suitable for compatible medium-viscosity coating materials, depending on the paint manufacturer’s instructions and the amount of thinning used.

Potential applications include compatible:

• Automotive base coats
• Clear coats
• Primers
• Enamels
• Lacquers
• Furniture coatings
• Metal paints
• Wood-finishing materials

Actual suitability depends on the material viscosity, thinning ratio, air pressure and spray technique.

Optional 1.3–1.7mm Nozzle Compatibility

The supplied specification lists optional nozzle sizes within the 1.3–1.7mm range.

Recommended catalogue wording:

Standard Nozzle: 1.5mm
Optional Nozzle Compatibility: 1.3–1.7mm range

Do not state that all optional nozzles are included unless they are physically supplied in the package.

Smaller nozzles may suit compatible thinner finishing materials, while larger nozzles may support suitable higher-viscosity coatings. Always follow the paint manufacturer’s recommended nozzle size.

29–50 PSI Operating Pressure

The DOOTOL DTQ8020 has a listed operating-pressure range of 29–50 PSI.

The appropriate pressure depends on:

• Paint viscosity
• Nozzle size
• Desired spray pattern
• Air-hose length
• Air-hose diameter
• Compressor output
• Regulator setting
• Painting distance
• Required finish
• Environmental conditions

Begin with a suitable lower pressure and test the spray pattern on scrap material before painting the final surface.

Excessive pressure may increase overspray and paint mist. Insufficient pressure may result in poor atomisation, uneven coverage or paint droplets.

200–320mm Spray-Pattern Width

The supplied specification lists a spray-pattern width of approximately 200–320mm.

The actual pattern width may vary based on:

• Fan-control setting
• Distance from the workpiece
• Operating air pressure
• Paint viscosity
• Nozzle condition
• Material-flow setting
• Spray-gun angle
• Operator technique

Maintain a consistent distance and keep the spray gun perpendicular to the surface for more even coating.

HVLP Pneumatic Spray Operation

The product is positioned as an HVLP pneumatic spray gun.

HVLP means high volume, low pressure. This spray method is intended to atomise compatible coating materials while operating at relatively controlled pressure.

Potential benefits may include:

• Controlled coating application
• Reduced material bounce-back
• Improved transfer efficiency
• Smoother finishing
• Better control on detailed surfaces
• Lower overspray when correctly adjusted

Actual performance depends heavily on compressor airflow, regulator settings, material preparation and operator technique.

Adjustable Spray-Pattern Control

The spray-pattern control allows the operator to change the fan shape and width according to the surface being painted.

A wider fan may be suitable for:

• Car panels
• Doors
• Furniture surfaces
• Cabinets
• Large metal sheets

A narrower pattern may be useful for:

• Small components
• Edges
• Corners
• Touch-up work
• Detailed areas

Test and adjust the pattern before beginning the final coat.

Adjustable Paint-Flow Control

The paint-flow adjustment helps regulate how much coating material passes through the nozzle.

Reducing the material flow may provide better control for lighter coats and detailed work. Increasing the flow may support faster coverage on suitable larger surfaces.

Paint flow should be balanced with:

• Air pressure
• Nozzle size
• Paint viscosity
• Spray distance
• Movement speed
• Required coating thickness

Excessive material flow may cause runs, sagging or uneven coating.

Adjustable Air Control

The spray gun appears to include an air-adjustment control for regulating the airflow entering the gun.

Correct airflow is important for proper atomisation and finish quality.

The operator should use an air regulator and moisture separator between the compressor and spray gun for more consistent spraying.

Metal Spray-Gun Body

The product page lists a durable metal construction and lightweight spray-gun design.

The metal body supports suitable workshop handling while remaining comfortable for controlled spraying.

Protect the spray gun from:

• Heavy impact
• Corrosive chemicals
• Dried paint accumulation
• Water entering the air system
• Contaminated compressed air
• Improper storage

Easy-Grip Trigger Design

The handle and trigger are designed for controlled operation during painting.

The lightweight format may help reduce hand fatigue during suitable spray jobs. However, regular breaks are recommended during longer painting sessions.

Suitable for Automotive Painting

The DOOTOL DTQ8020 may be used for compatible automotive refinishing applications such as:

• Car panels
• Motorcycle parts
• Bumpers
• Doors
• Bonnets
• Fenders
• Automotive primers

Suitable for Primer and Finish-Coat Application

The 1.5mm nozzle may be suitable for selected primers and finish coatings when the material is correctly prepared.

Thicker primers may require:

• Additional thinning
• A larger compatible nozzle
• Higher airflow
• Different material-flow adjustment

Never thin a coating beyond the manufacturer’s permitted ratio solely to make it pass through the spray gun.

Compressor Compatibility

The product page states compatibility with standard workshop air compressors.

However, the required air-consumption specification is not currently provided.

Before recommending a compressor, confirm:

• Air consumption in CFM
• Air consumption in litres per minute
• Recommended compressor tank size
• Minimum compressor output
• Required hose diameter
• Air-inlet thread size
• Maximum safe pressure

PSI alone is not enough to determine whether a compressor can operate the spray gun continuously.

Moisture Separator and Regulator Recommendation

For better results, use:

• Air-pressure regulator
• Moisture separator
• Oil and water filter
• Clean compressed-air hose
• Correct air fitting
• Suitable compressor

Moisture or oil in the compressed-air line may cause surface defects, contamination or inconsistent atomisation.

Paint Preparation

Spray Technique

For a smoother finish:

• Hold the gun perpendicular to the surface
• Maintain a consistent spraying distance
• Begin moving before pulling the trigger
• Release the trigger before stopping movement
• Overlap each pass evenly
• Maintain a steady travel speed
• Avoid excessive paint flow
• Apply multiple controlled coats rather than one heavy coat

Always perform a test spray before painting the final surface.
