How is polyurea sprayed?

Spraying polyurea is a common method of applying anti-corrosion materials. Here are some basic spraying tips:

1. Preparation: First, the surface to be sprayed needs to be cleaned to ensure that it is free of dirt, dry, and flat. Then, the polyurea material is mixed according to the area to be sprayed and the required thickness, and stirred thoroughly using a mixer.

2. Spraying: Pour the mixed polyurea material into the spraying equipment and spray it with a spray gun. When spraying, pay attention to adjusting the air pressure, which is generally controlled between 3-5bar and adjusted appropriately according to the required thickness. At the same time, control the distance and movement speed of the spray gun, generally keeping the distance between 30-50cm and the movement speed between 0.5-1.0m per second.

3. Details: For details that require special attention, such as edges and corners, a brush or a small spray gun can be used for detailed spraying.

4. Construction requirements: During spraying, pay attention to preventing the influence of wind and sand, dust, etc. from the outside, and also pay attention to the safety of the spraying personnel.

It is important to note that safety and environmental protection should be taken into account during the spraying process of polyurea. Protective equipment such as safety glasses, gloves, and shoes should be worn during operation, and proper ventilation should be maintained to ensure a safe working environment. Additionally, if repairs or special treatments are required, they should be handled according to specific requirements and material properties.
