Sprayer Operating Sequence

Professional Spray Equipment Operation Guide: Standardized Procedures for Enhanced Construction Quality

As an essential tool in modern decoration and industrial coating, the sprayer requires proper operation to enhance work efficiency and ensure construction quality. Let's quickly master the essentials of sprayer operation through six simple steps.

Step 1: Conduct a thorough inspection before construction begins.

Before using the spray machine, conduct a thorough inspection of the equipment. Pay particular attention to the spray gun, nozzle, and paint lines to ensure they are undamaged. Verify that all connections are secure and leak-free. Mix the paint and thinner according to the specified ratio in the manual. Prepare all necessary safety gear, including protective masks, gloves, and goggles. Meticulous preparation effectively eliminates potential hazards and lays a solid foundation for subsequent operations.

Step 2: Rigorous Calibration of Equipment Parameters

After dispensing the prepared coating into the material tank, scientifically adjust the equipment pressure, flow rate, and nozzle specifications based on the coating properties (such as viscosity and coverage) and application requirements. After calibration, always test spray on a scrap board to observe atomization quality and coating uniformity. If uneven spraying or overspray occurs, recalibrate the parameters until the desired results are achieved.

Step 3: Master the Spraying Distance and Angle

During formal application, the spray gun must be held perpendicular to the substrate surface, with the distance strictly maintained between 30 and 50 centimeters. Excessive distance may cause uneven dispersion of the coating, while excessive proximity may lead to accumulation and sagging. Simultaneously, maintain a consistent speed when moving the spray gun to avoid fluctuations that could compromise coating uniformity.

Step 4: Follow the scientific spraying sequence

Spray application must be performed in layers following the sequence “from top to bottom, left to right.” Each coat should partially overlap the preceding one (typically by one-third of its width). Avoid repeated spraying of the same area to prevent localized thickening of the coating, which can cause sagging or uneven drying.

Step 5: Thoroughly clean after use.

After completing the application, immediately clean the equipment: First, pour back any remaining paint. Add the dedicated thinner and circulate it through the lines and spray gun until the fluid runs clear. Then disassemble components such as the nozzle and filter for separate cleaning. After 100% removal of residual paint, wipe dry and reassemble. Store in a dry, well-ventilated area.

Step 6: Regular Maintenance

Establish a maintenance schedule for equipment. Inspect wear-prone components (seals, filters, etc.) monthly and replace them promptly. Regularly lubricate moving parts and clean filters and nozzle passages. Apply rust prevention to critical components during extended downtime to ensure the equipment remains in stable working condition.
