III. Detailed Explanation of Core Selling Points

Wireless lithium battery design, say goodbye to cable constraints

Equipped with a 21V lithium battery, no external power supply or air pump is required. It allows for free operation outdoors, at heights, and in confined spaces. Without dragging a power cord and a bulky air pump, its mobility is greatly improved, making it particularly suitable for renovation, outdoor railings, and patio furniture spraying.

Fine atomization + multi-mode adjustment for controllable spraying results

Supports multi-dimensional adjustment of flow rate, atomization level, and spray shape (circular/fan-shaped/horizontal/vertical), easily adapting to different paints and scene requirements. The fine atomization effect reduces brush marks and runs, resulting in a more even and smooth paint film, making it easy for beginners to use.

Large-capacity spray bottle reduces frequent refills

Comes with a standard approximately 800ml large-capacity transparent spray bottle, allowing for large-area work with a single fill. The transparent bottle allows for easy monitoring of remaining paint, preventing paint shortages. The bottle is detachable and can be easily cleaned with water or thinner after use.

Ergonomic design for comfortable long-term use

The spray gun features a non-slip grip design with a reasonable weight distribution for comfortable handling. The trigger-type switch is simple to operate, reducing hand fatigue even during extended spraying sessions, making it very user-friendly for home DIY scenarios.

Multifunctional Adaptability, Covering Diverse Coating Needs

Compatible with a variety of common paints, such as:

Wall latex paint renovation and spot repair

Wood/metal paint spraying for furniture, wooden doors, and wrought iron railings

DIY crafts, model painting, and small object renovation

IV. Usage and Maintenance Points

Paint Dilution Requirements: Dilute according to the paint instructions before use (usually requires a filter to remove impurities) to avoid nozzle clogging; high-viscosity paints may not atomize properly and should be tested beforehand.

Spraying Techniques: Keep the spray gun perpendicular to the spray surface, move at a constant speed, and maintain a distance of approximately 15-25cm to reduce drips and unevenness; multiple thin coats yield better results than a single thick coat.

Cleaning and Maintenance: Thoroughly clean the nozzle, spray bottle, and internal channels after each use to prevent paint from drying and clogging; dry thoroughly before storage; charge and maintain the lithium battery according to the instructions.

Safety Tips: Wear a mask and goggles while spraying, ensure good ventilation in the work area, and keep away from open flames and high-temperature sources. V. Applicable Scenarios

Home DIY: Wall renovation, furniture repainting, door and window painting, balcony railing rust prevention

Handicraft Creation: Model painting, figurine painting, small item DIY transformation
