Automatic Reciprocating Spraying Machine for Waterborne Sand & Real Stone Paint – Customizable Width up to 1300mm with PLC Control

This customizable waterborne sand spraying machine is specifically engineered for efficient application of high-viscosity decorative coatings, including waterborne sand (水包砂), real stone paint (真石漆), waterborne multi-color paint (水包水), and texture coatings. Available in pressure tank, automatic reciprocating, and airless texture configurations.

The system is fully customizable in tank capacity, nozzle size, pressure range, spray width, and automation level. Unlike conventional paint sprayers, waterborne sand sprayers are engineered to handle coatings containing colored sand particles and thickeners without clogging, delivering consistent texture effects on building facades and decorative panels.

Working Principle: The coating is pressurized (by air pressure in a pressure tank or by a screw pump in airless models) and fed to the spray gun, where atomization occurs through specially designed nozzles. For pressure tank models, the bottom-discharge design eliminates the need for suction tubes, minimizing material waste.

• Exterior wall decoration: Building facades, residential complexes, commercial buildings
• Construction materials: Insulation decorative panels, ALC panels, cement boards
• Interior decoration: Feature walls, textured finishes
• Industrial coatings: Anti-corrosion, fire-retardant coatings on steel structures
• Stone effect finishes: Granite-like, marble-like decorative surfaces
