In the world of road maintenance, seal coating is a crucial process that helps extend the life of asphalt surfaces and improves their overall durability. The equipment used in this process is vital to ensuring that the job is done correctly, and one of the most important pieces of equipment is the seal coat tank with an agitator. This article explores the function, types, and considerations for selecting and maintaining a seal coat tank with an agitator.
What is a Seal Coat Tank with Agitator?
A seal coat tank is used for storing and dispensing the liquid sealant that is applied to asphalt surfaces to protect them from water, oils, and UV damage. The agitator is an integral part of the tank, designed to keep the sealant mixed and evenly distributed. Sealants can be prone to separating or thickening over time, especially if they are stored for long periods. The agitator ensures that the liquid remains in a consistent, workable state throughout the application process.
The agitation system within the tank ensures that the sealant is uniformly mixed, preventing the solid materials from settling at the bottom, which could lead to an uneven application or blockages in the dispensing system.
Key Features of Seal Coat Tanks
Seal coat tanks come in various configurations depending on the needs of the operation. Here are the main features to consider:
1. Tank Capacity
The capacity of the tank is a crucial factor to consider. Tanks typically range from small, trailer-mounted models to larger, truck-mounted versions. The right size depends on the scale of your project, how much surface area needs to be covered, and how frequently you plan to use the tank.
The agitator plays a vital role in ensuring that the sealant maintains its effectiveness. The two main types of agitation systems are:
3. Heating System
Many sealant materials, particularly those used for road repairs, need to be heated to maintain a liquid state suitable for application. A heating system helps ensure that the sealant is at the optimal temperature for application, ensuring smooth distribution and faster curing times. Some tanks come equipped with diesel or propane-powered heating systems that allow you to maintain the desired temperature while on the job.
4. Dispensing System
The dispensing system must be reliable and efficient. It typically consists of a sprayer or hose system designed for controlled application. High-pressure sprayers are often used to apply the sealant evenly to the road surface. Some tanks feature automatic dispensing systems that regulate the flow of the sealant, reducing waste and improving efficiency.
5. Agitator Speed Control
Some advanced seal coat tanks come with the ability to control the speed of the agitator. This allows the operator to adjust the mixing intensity depending on the material’s thickness or condition. For example, when working with thicker sealants, a slower agitation speed may be needed to prevent air bubbles from forming, while thinner liquids can be mixed more rapidly.
Benefits of Using Seal Coat Tanks with Agitators
The use of a seal coat tank with an agitator comes with several advantages:
1. Consistency in Application
The primary benefit of an agitator is that it keeps the sealant consistently mixed, preventing clumps or separation of materials. This ensures that the product is applied evenly across the entire surface, which improves the quality of the finish and the longevity of the sealant.
2. Efficiency in Operation
An agitator-equipped tank allows for continuous operation. Operators don't have to worry about manually stirring or mixing the sealant during the job, making the process more efficient and reducing downtime.
3. Reduced Maintenance
By maintaining a uniform mix, the agitator helps reduce the risk of clogging the dispensing system with solidified material. This not only improves the speed and quality of the application but also reduces the need for regular maintenance and repairs of the system.
4. Better Material Handling
Some sealants, especially those with high solid content, need constant mixing to prevent separation. Without agitation, these materials could become unusable, and the tank could be left with residual material that’s difficult to clean. The agitator ensures that all of the sealant can be used efficiently and that the equipment is easier to clean post-application.
Common Seal Coat Tank Problems and Solutions
While seal coat tanks with agitators are designed to be reliable, problems can arise during use. Here are some common issues and solutions:
1. Agitator Motor Failure
If the agitator stops working, the most likely cause is a motor or hydraulic system failure. This can usually be fixed by checking the power supply to the motor, inspecting the drive belts or hoses, and ensuring the hydraulic pump is functioning properly.
2. Clogged Dispensing System
A clogged dispensing system can occur if the sealant becomes too thick or if debris gets into the hose. To prevent this, regularly clean the nozzle and hose, and ensure the sealant is properly heated before use.
3. Sealant Separation
If you notice that the sealant is separating into layers, the agitator might not be working properly. Check the speed settings of the agitator and ensure that it’s running at the appropriate speed for the material being used. If needed, use a more powerful agitator or adjust the viscosity of the sealant.
4. Fuel or Heat Issues
If the sealant isn’t heating correctly, check the heating system for issues such as fuel blockages or thermostat malfunctions. Ensure the heating element is clean and operational.
Conclusion
A seal coat tank with an agitator is an essential tool for maintaining and protecting asphalt surfaces. By understanding the features and functions of this equipment, businesses can make informed decisions that optimize their operations. From maintaining consistency in the sealant application to improving overall efficiency, these tanks play a pivotal role in road maintenance and repair. Whether you are looking to invest in new equipment or improve your existing machinery, focusing on the size, agitation system, heating capabilities, and overall functionality will help ensure you select the right seal coat tank for your needs.

- Small Tanks (Up to 500 gallons): Ideal for smaller jobs and areas that don't require extensive sealant.
- Medium Tanks (500–1,000 gallons): Suitable for medium-sized parking lots or road segments.
- Large Tanks (Over 1,000 gallons): Used for large-scale commercial projects or continuous road applications.
The agitator plays a vital role in ensuring that the sealant maintains its effectiveness. The two main types of agitation systems are:
- Mechanical Agitators: These are powered by the engine and use rotating paddles or blades to mix the sealant.
- Hydraulic Agitators: Powered by hydraulic pumps, these agitators offer smoother and more consistent mixing, especially for larger tanks.
