A polyurea spraying machine, also known as a polyurea machine or polyurea spraying equipment, is a specialized piece of spraying equipment. It is equipped with an advanced high-pressure mixing system that can fully mix two liquid raw materials in proportion instantly. Then it is sprayed on the surface of the object at a very fast speed, and a strong and dense coating can be formed in just a few seconds. People often use this machine in building waterproofing, in the field of industrial anti-corrosion, and on car interiors. No matter what kind of spraying needs, it can handle it with ease!

Polyurea Spraying Equipment: Multiple Working Scenes
The application scenarios of polyurea spraying equipment cover multiple industries.
- In the field of construction, in addition to waterproof spraying of basements and roofs, special places such as swimming pools and tunnels can also form seamless waterproof membranes through it to prevent moisture penetration.
- In the chemical industry, pipelines are eroded by various chemical substances all year round. The corrosion-resistant coating sprayed by polyurea spraying equipment can be put on “protective armor” for pipelines.
- In automobile manufacturing, a polyurea sprayer can not only spray chassis armor, but also be used for interior parts such as car seats and dashboards to enhance their wear resistance and anti-fouling properties.
- In addition, it also performs well in fields such as stadiums and shipbuilding. Wherever there is a need for spraying, there it is! Come and see how it can empower your project!
Polyurea Machine Function
- This equipment is more powerful than you can imagine. The precise metering system, with an error of no more than 1%, ensures that the raw material mixing ratio is accurate and the coating quality is stable from the source. High-pressure spraying technology allows the coating to be closely combined with the substrate, and the adhesion reaches the industry-leading level, and it difficult to fall off even with a hammer.
- Its spraying efficiency is extremely high, and it can spray hundreds of square meters per hour, which is 3-5 times faster than traditional spraying equipment, greatly shortening the construction time. Moreover, the equipment is flexible to operate, and even complex-shaped objects, such as sculptures and specially-shaped building components, can be perfectly handled by the polyurea spraying machine. With it, no matter how difficult the spraying task is, it can be easily completed. Come and experience it!

Polyurea Spraying Machine Exported to Russia
Challenge
Before purchasing polyurea spraying equipment, the Russian client faced the following major issues:
- Harsh working environment: Russia has frigid winters with low on-site temperatures. Ordinary equipment cannot guarantee raw material fluidity and good spraying results.
- High operation difficulty: The original equipment was complicated to use. New workers required long training periods, and uneven coating thickness led to a high rework rate.
- High logistics risks: Long-distance international transportation easily damaged precision parts due to jolting and vibration, affecting delivery quality.
- Low working efficiency: Manual tools and low-end equipment worked slowly and failed to meet project schedules. The coating thickness error exceeded ±0.5 mm, weakening thermal insulation and anti-corrosion performance.
Solution
YG provided customized polyurea spraying equipment (compatible with 220V/380V) and a complete set of solutions based on client requirements:
- Equipment selection: Hydraulic drive is adopted. The main unit is equipped with an independent hydraulic station to deliver strong and stable power for continuous operation in low temperatures. The supporting automatic heating hose can reach a maximum length of 90 meters, keeping materials at a constant temperature from the machine to the spray gun for winter construction in Russia.
- Operation optimization: The machine features a simple and intuitive interface. With Chinese-Russian bilingual manuals and on-site video training, workers can master basic operations within one day. The intelligent control system enables precise adjustment of flow rate (2-12kg/min) and coating thickness.
- Reliable spraying quality: YG equipment delivers even spraying. The coating thickness error is controlled within ±0.3 mm, better than the original ±0.5 mm, which fully meets strict standards for cold storage tanks, storage tanks, and other scenarios.
- Safe transportation: Custom shockproof wooden cases and internal EPE cushioning materials are used. Professional logistics vehicles provide full tracking. Key components, including hydraulic stations and heating hoses, are reinforced separately to prevent damage during long-distance transit.
Results
The client achieved remarkable improvements after using YG equipment:
- Higher efficiency: The spraying speed increased by 40% (peak value rose from 8kg/min to 12kg/min). The construction period for one large storage tank was shortened from 5 days to 3 days.
- Higher precision: The coating thickness error is kept within ±0.3 mm, cutting the reject rate by 50% and eliminating rework.
- Lower material consumption: Thanks to uniform spraying, the raw material consumption is stably maintained at 40 kg per cubic meter of foam (20 kg for Component A and 20 kg for Component B), reducing material waste by about 8%.
Polyurea Machine FAQ
Q: What is the difference between pneumatic and hydraulic polyurea machines? How to choose?
A: The main differences lie in power source and stability.
- Pneumatic equipment: The main unit, material pump, and spray gun all rely on a large air compressor for power. It is highly dependent on air supply, and fluctuating air pressure may affect spraying stability.
- Hydraulic equipment: It comes with a built-in independent hydraulic station and self-contained power supply, requiring no air pump. Only a small air compressor is needed to drive the material pump and spray gun. The hydraulic system delivers stronger power, higher and more consistent pressure, which pneumatic equipment cannot match.
Recommendation: Choose hydraulic equipment first if you require high spraying efficiency, steady pressure, and long continuous operation.
Q: How much raw material is needed to produce 1 cubic meter of foam?
A: Based on the standard ratio (50% for Component A and 50% for Component B), about 40 kilograms of raw materials are required per cubic meter of foam, including 20 kg of Component A and 20 kg of Component B.
Q: What is the spraying flow rate? Is it adjustable?
A: The flow rate ranges from 2 to 12 kg/min. It can be adjusted according to construction thickness and efficiency to meet different areas and process requirements.
Q: What foam thickness options are available? What are their applicable scenarios?
A: Two standard foam thicknesses are available: 5 cm and 10 cm. Details are as follows:
| Thickness | Foam Type | Features | Application Scenarios | Coverage per Ton of Material |
| 10 cm | Water-blown foam | Good sound insulation, eco-friendly (contains no ozone-depleting substances) | Sound and thermal insulation for light steel houses and wooden houses | About 500~600 square meters |
| 5 cm | Rigid polyurethane foam | Excellent thermal insulation | Cold storage, tank and pipeline insulation | About 440 square meters |
Note: Water-blown foam is more eco-friendly for residential buildings. Rigid polyurethane foam offers better heat preservation for industrial refrigeration and tank insulation.
Q: What is the maximum length of the supported heating hose? Does the machine support automatic heating?
A: The machine supports heating hoses up to 90 meters long. It features automatic heating to keep the material temperature stable inside hoses, ensuring good construction quality for long-distance spraying and work in low-temperature environments.
Q: What are the requirements for the matching air compressor?
A: Recommended air compressor parameters:
- Power: 7.5 kW
- Air displacement: 0.9 cubic meters per minute
- Working pressure: 8 kg (approx. 0.8 MPa)
An air compressor meeting the above standards ensures the stable operation of the material pump and spray gun.
Q: What voltage options does the equipment support?
A: This series is available in 220V and 380V, adapting to power supply standards in different countries and factories. Please confirm the on-site voltage before ordering.
