The construction industry is one of the most important pillars of national infrastructure development, with massive annual investments in fixed assets. However, during periods of rapid growth, project quality is sometimes compromised. Driven by profit, some companies may cut corners or use substandard materials, resulting in serious safety hazards and potential project failures. To prevent such incidents, government authorities must strengthen market supervision, while construction enterprises need to enhance management practices and adopt advanced, reliable equipment.
Among the essential tools for modern construction is the automatic mortar jetting machine, a high-performance solution designed to improve efficiency, ensure quality, and reduce labor intensity. Below are its core features and operational guidelines.
High Speed and Efficiency
A single automatic mortar jetting machine (e.g., CG-350 model) can spray over 1,000 m² per day, equivalent to the workload of 20 skilled workers. This reduces construction time and labor costs significantly.
Easy Operation and No Scaffolding Required
These machines eliminate the need for scaffolding and additional mobile platforms. They can freely spray interior corners, ceilings, and complex structures, saving material and frame costs.
Versatile for Interior and Exterior Use
Automatic mortar jetting machines are suitable for both interior wall finishing and exterior façade projects.
Low Investment, High Returns
With a spraying capacity of 1,000 m² per day, at an average market price of 10 RMB/m², each unit can generate profits of approximately 8,800 RMB per day after deducting labor and operational expenses.
Superior Spraying Quality
These machines operate with high flow and pressure (up to 3 MPa), ensuring better adhesion and compactness than standard manual methods—exceeding national construction standards.
Multi-Purpose Application
Capable of spraying mortar, fire-retardant coatings, refractory materials, putty, and standard wall coatings, automatic mortar jetting machines perform reliably across diverse environmental and surface conditions.
Before each shift, operate the hand oil pump several times to lubricate the transmission parts.
After powering on, check the motor’s rotation direction. If incorrect, adjust the power phase lines.
Connect the hose and nozzle, flush with clean water (5L) to prepare the system.
Add mortar, putty, or paint to the hopper, then start spraying (activate the air compressor and open the damper).
Never operate the machine dry—ensure materials and water are always present in the hopper.
After work, thoroughly clean the hopper, hoses, and nozzle to prevent material solidification.
For extended downtime, remove the booster screw, oil it, and store it properly.
Adjust the booster stator bolt or rubber sleeve if pumping pressure drops.
Wet the target surface before spraying to enhance adhesion.
Avoid stirring materials in the hopper with foreign objects during operation.
In case of blockage, use the reverse-pressure method via the compressor to clear the hose.
Always wear safety equipment such as helmets, goggles, and protective clothing.
Periodically check wear parts (rubber sleeves, booster screws) and adjust compression bolts to maintain optimal flow and pressure.
Automatic mortar jetting machines are not only suited for large-scale construction projects but also play an increasingly vital role in residential and commercial renovation, including:
Interior wall plastering before painting or wallpapering
Applying waterproof layers in kitchens, bathrooms, and basements
Spraying thermal insulation mortar for energy-efficient housing
Decorative stone and textured paint finishes for facades
Fireproof coatings for safety-enhanced building design
Their ability to deliver uniform coverage, reduce manual labor, and speed up project timelines makes them indispensable for contractors aiming for both quality and profitability.
In a competitive and fast-evolving construction market, investing in automatic mortar jetting machines ensures higher productivity, lower operational costs, and superior construction quality. By adopting advanced spraying technology, construction companies can strengthen their market reputation, deliver safer projects, and meet modern housing demands with greater efficiency.
For enterprises seeking reliable equipment, automatic mortar jetting machines are a smart, future-oriented investment that combines speed, precision, and economic benefits.
