Using polyurea joint filler to fill concrete cracks offers numerous advantages that make it an excellent choice for both residential and commercial applications. Here’s a detailed exploration of why polyurea is often the preferred material for this purpose:
1. Superior Durability
Polyurea joint fillers are known for their exceptional durability. They can withstand a wide range of environmental conditions, including extreme temperatures and moisture. Unlike other materials, polyurea maintains its integrity over time, resisting cracking and chipping. This durability makes it ideal for areas subjected to heavy traffic, such as driveways, parking lots, and industrial floors.
2. Fast Curing Time
One of the standout features of polyurea is its rapid curing time. While traditional concrete fillers may take days to set, polyurea can cure in as little as 30 minutes. This quick turnaround allows for minimal downtime, making it especially advantageous for businesses and homeowners who need to use the space soon after repairs.
3. Flexibility and Elasticity
Polyurea is highly flexible, which allows it to accommodate slight movements in the concrete. Concrete naturally expands and contracts with temperature fluctuations, and the elasticity of polyurea helps prevent the filler from cracking under stress. This flexibility is crucial in maintaining the integrity of the repair over time.
4. Excellent Adhesion
Polyurea adheres strongly to concrete surfaces, creating a lasting bond that helps prevent future cracking and water infiltration. This strong adhesion is vital for maintaining the longevity of the repair and ensuring that the filler stays in place under various conditions.
5. Water and Chemical Resistance
Another significant advantage of polyurea joint filler is its resistance to water and various chemicals. This feature is particularly beneficial in environments exposed to spills, such as garages, warehouses, and industrial settings. The water-resistant properties prevent moisture from seeping into the cracks, which can lead to further damage and deterioration of the concrete.
6. Aesthetic Appeal
Polyurea fillers can be tinted or colored to match the surrounding concrete, providing a more aesthetically pleasing finish compared to traditional fillers. This is especially important for visible areas, as it helps maintain the overall appearance of the concrete surface.
7. Low Maintenance Requirements
Once applied, polyurea joint fillers require minimal maintenance. Their durability and resistance to wear mean that they do not need frequent reapplication, saving both time and money in the long run.
8. Cost-Effectiveness
While the initial cost of polyurea fillers may be higher than some alternatives, their long lifespan, reduced maintenance needs, and quick installation often make them a more cost-effective solution. By preventing further damage and the need for extensive repairs, polyurea can ultimately save money over time.
9. Environmentally Friendly Options
Many polyurea products are now formulated to be environmentally friendly, containing low levels of volatile organic compounds (VOCs). This makes them a safer choice for both applicators and the environment, aligning with growing sustainability concerns.
10. Versatility
Polyurea can be used in a variety of applications beyond just filling cracks. It is also suitable for joint filling, resurfacing, and coating, making it a versatile choice for numerous concrete repair projects. Whether dealing with expansion joints, saw cuts, or general wear and tear, polyurea can handle a wide range of challenges.
Conclusion
In summary, using polyurea joint filler to fill concrete cracks offers significant advantages in terms of durability, flexibility, and quick curing times. Its ability to resist water and chemicals, along with excellent adhesion and aesthetic appeal, makes it a smart choice for anyone looking to maintain or repair concrete surfaces. By investing in polyurea joint filler, you’re not only addressing existing issues but also proactively preventing future problems, ensuring a long-lasting and visually appealing result.
USAGE
 
Dispensing
Joints can be filled in one or two passes, depending upon joint depth and dispensing tip used. Preferred method is to fill from bottom to top using a dispensing tip that fits into the joint. Take care not to entrap air bubbles. Slightly overfill the joint, leaving a crowned profile, and allow to cure.
Finishing
The crown may be easily razored off as early as 15 minutes after placement, depending upon temperature. We recommend testing various shave times to find the optimal shave which results in a filler profile that is flush with the floor’s surface and free of any film from material overfill. If shave time is substantially delayed or if temperatures are low, RS 88 shaving process may be more labored. Should filler cure below the floor surface (due to settlement into the void at base of joint, etc.), remove top 1/2” of filler and re-apply RS 88. Grinding/polishing operations should be deferred for one hour or more after placement. (If using Fast Pack addition, 25-30 minutes or more).
