1. Main Functions of a Professional Touch-Up Spray Gun

Fine Spraying, Improving Repair Quality

Ideal for spot touch-ups (such as car scratches and furniture paint peeling), minimizing color shift and spray marks.

Adjustable spray width (fan or circular) and paint output to suit different repair needs.

Improved Work Efficiency

Compared to traditional brush application, spray guns are faster to apply and are particularly suitable for spraying large areas or complex curved surfaces.

Excellent atomization results in a uniform paint film, minimizing rework.

Paint Conservation

High-pressure airless or HVLP (High Volume Low Pressure) spray guns reduce paint scatter and material waste.

Compatible with a Wide Range of Paints

Applicable to a variety of materials, including water-based and oil-based paints, clearcoats, and primers, suitable for use on a variety of surfaces, including automobiles, wood, and metal.

2. Key Maintenance Tips for Touch-Up Spray Guns

Cleaning After Daily Use

Immediate Cleaning (to prevent paint curing and clogging):

Emptying the Paint: Drain any remaining paint from the spray gun. Solvent Flushing:

Add an appropriate amount of thinner (such as banana oil or a specialized cleaning agent) to the paint can.

Spray until the cleaning solvent comes out.

Disassembly and Cleaning:

Remove the nozzle, needle valve, and air cap, and clean the fine openings with a soft brush.

Stubborn residue can be removed with an ultrasonic cleaner.

Lubricate Key Components:

Apply a small amount of specialized grease (such as silicone grease) to the needle valve and seal to prevent dry wear.

Caution:

Do not poke the nozzle with metal tools to avoid damaging the delicate structure!

Do not mix cleaning agents for water-based and oil-based paints.

Regular Inspection and Maintenance

Checking the Seals:

After assembly, spray dry and observe for leaks (a hissing sound indicates seal deterioration).

Replacing Consumable Parts:

Replace the nozzle, needle valve, and seal every 6-12 months (depending on frequency of use).

Air Filter Maintenance:

Clean or replace the filter element regularly to prevent moisture and impurities from entering the spray gun.

Long-Term Storage Recommendations:

After thorough cleaning, disassemble the nozzle and store it separately. Apply anti-rust oil to the sprayed parts and store in a dry environment.

3. Usage Precautions

Personal Protection:

Wear a respirator (N95 or higher), goggles, and gloves to avoid inhaling paint mist.

Environmental Requirements:

The spraying area must be well ventilated and away from open flames (paint solvents are flammable).

Paper Compatibility:

Select a paint with the appropriate viscosity based on the type of spray gun (HVLP, LVLP, etc.).
