A project's success pivots on the foundation; surface preparation. Correctly prepared surfaces promote superior adhesion, ensuring long-lasting results.

  • Cleaning: Using industrial-grade solvents or detergents, remove contaminants like dirt, oils, or residues. It's essential to ensure no residue from the cleaning agents remains, as this might affect adhesion.
  • Dust and Rust Removal: Employing techniques like high-pressure washing or sandblasting ensures the surface is free from rust, old paint, or loose debris. Sandblasting, in particular, can provide a textured surface ideal for adhesion.
  • Surface Profiling: This involves creating a slightly abrasive profile on the surface. Similar to sanding wood before painting, this process enhances the bond strength, ensuring the polyurea effectively adheres to the substrate.

2. Application of the Polyurea Coating


Polyurea's distinguishing feature is its two-component system consisting of a isocyanate and resin blend. When these components are mixed, a rapid chemical reaction ensues, resulting in an extremely fast cure rate. Let's break down the procedure:

  • Storage: The isocyanate and resin are stored separately to prevent premature reactions. These containers are often colour-coded or labeled distinctly to avoid confusion during the application process.
  • Merging at the Nozzle: Modern spray rigs are designed to mix these components precisely at the spray gun nozzle. This allows the polyurea to remain in its liquid form until the very moment of application. This maximises the working time and ensures the mixture is fresh. This promotes optimal adhesion and curing.
  • High-Pressure, Heated Spray Rig: The application process requires a specific type of equipment. The spray rig is not only high-pressure to ensure uniform distribution but is also heated. The heat optimises the viscosity of the polyurea mixture, ensuring smoother application, reducing the likelihood of imperfections or bubbles, and promoting better adhesion.

Factors to Consider

1. Equipment Maintenance and Calibration

  • Avoid Nozzle Clogs: Over time, residues can build up at the nozzle, disrupting the smooth flow of polyurea during application.
  • Ensure Calibration: Consistency is key. Regularly calibrating the equipment ensures the isocyanate and resin blend in the correct ratios, promoting the best possible chemical reaction and end product.
  • Control Temperature: The equipment’s heating mechanism needs to be monitored. If the polyurea mixture becomes too hot or not heated enough, it can influence its behaviour during application and curing.

2. Ambient Conditions:

  • Temperature: While polyurea can be applied in a range of temperatures, extreme cold can cause the material to become too viscous, leading to challenges in application. Conversely, extremely high temperatures might accelerate the reaction rate, reducing the time professionals have to work with the material.
  • Humidity: High levels of moisture in the air can affect the behaviour of polyurea during application. Polyurea is moisture-cured, meaning it reacts with humidity. If too much moisture is present during application, it can cause defects like foaming, blistering, or poor adhesion.
  • Ventilation: Especially when working indoors, ensuring proper ventilation is critical. This not only helps control humidity but also ensures that any fumes from the application process are safely dispersed.

In essence, while the application of polyurea waterproofing has its intricacies, understanding and controlling these factors can lead to a flawless and long-lasting result.

3. Curing Process and Timeframes


The curing process of polyurea is an intricate dance of chemistry that's both swift and efficient. Let’s explore it step-by-step:

  1. Initial Gel Phase: Moments after the polyurea is sprayed onto the surface, it enters the “gel phase”. This is a transitional stage where the material starts to solidify but hasn't achieved its full rigidity. This phase is relatively short, often lasting just a few seconds to a couple of minutes.
  2. Tack-Free Phase: Immediately following the gel phase, polyurea transitions to the tack-free state. In this stage, the surface can be touched without any material sticking when touched. This usually happens within a few minutes of application, effectively nullifying chances of dust, debris, or foreign particles compromising the finish.
  3. Full Cure Phase: While the surface is touch-ready almost instantaneously, polyurea's internal curing continues. Over the span of 24 to 48 hours, the compound bonds further, reaching its zenith in terms of both structural strength and chemical resistance.


The rapid curing of polyurea is not just a testament to its advanced chemistry but also offers tangible advantages to its users:

  1. Efficiency for Tight Deadlines: For projects with stringent timelines, polyurea is a game-changer. Its swift curing means subsequent stages of a project can commence without long intervals.

Polyurea, with its rapid cure time, minimises this downtime. Restaurants, retail stores, warehouses, and more can get back to serving customers or resuming operations in record time.
  3. Reduced Project Costs: Faster cure times can also translate to reduced labor costs. Workers don't need to be on-site for extended periods, waiting for materials to dry or cure. This efficiency can be especially beneficial for larger projects where labor costs can accumulate rapidly.

  4. Consistency in Application: With the quick-setting nature of polyurea, there’s a reduced window for errors to occur post-application. This can lead to more consistent results and less need for rework or touch-ups.

Overall, the curing properties of polyurea not only attest to its advanced nature but also offer significant real-world advantages, making it an increasingly popular choice in various sectors.

4. Finishing and Post-Application Considerations

After polyurea has undergone its rapid curing process, it is paramount to ensure the application is up to the expected standards. This entails meticulous observation and the use of specialised tools:

Inspection Tools and Techniques

  • Wet Film Thickness Gauges: Employing tools like wet film thickness gauges is crucial. These gauges are designed to measure the thickness of the polyurea layer while it's still wet, giving an immediate indication of whether the application is uniform. Consistency in thickness ensures the waterproofing's effectiveness and longevity.
  • Dry Film Thickness Gauges: Once the polyurea has cured, using a dry film thickness gauge can be advantageous. This tool uses magnetic induction or ultrasonic waves to determine the thickness of the dried polyurea coat, ensuring it meets project specifications.

Potential Imperfections to Watch For

  1. Pinholes: These tiny punctures, often invisible to the naked eye, can compromise the waterproofing properties of the polyurea layer. Over time, water or other substances could penetrate these holes, leading to potential damage.
  2. Blisters: These raised areas on the polyurea surface indicate trapped air or moisture. Blisters can weaken the coat's structural integrity, making the area more susceptible to breaches or peeling.
  3. Non-Adhering Zones: These are sections where the polyurea hasn't bonded well with the substrate. Such areas are vulnerable. They might peel off or get detached under stress or when exposed to water. This is obviously a problem and undermines the waterproofing purpose.

Corrective Measures

  1. Patchwork: For smaller imperfections like pinholes or minor non-adhering zones, patchwork can be done. This involves cleaning the area and applying a small amount of polyurea to seal the defect.
  2. Re-application: In cases where large sections of the surface exhibit imperfections or if there's a significant inconsistency in thickness, it might be prudent to consider re-application. While this is more time-consuming and could mean higher costs, ensuring the integrity of the polyurea coat is paramount for the long-term success of the waterproofing project.

While polyurea boasts rapid application and curing, the post-application phase is critical. A meticulous inspection, followed by appropriate corrective actions, ensures that the waterproofing serves its purpose effectively and endures over time.
