Polyurea coatings have emerged as one of the most robust waterproof and protective barriers suitable for various applications in residential, industrial, and commercial settings. While not a new technology, the use of Polyurea coating systems is rapidly gaining widespread acceptance, particularly in Terrace and Roof areas, where its benefits are becoming increasingly evident.
One of the key selling points of Polyurea coatings is their remarkable ability to withstand continuous exposure to standing water. These coatings, originally designed to protect terrace roofs, are also utilized as containment pond liners due to their leak-proof nature. An impressive feature is that Polyurea coatings dry quickly, allowing for immediate access just two minutes after application, without any need for downtime or waiting for the area to be “under construction.”
The outstanding waterproofing and protective capabilities of Polyurea are highly effective in safeguarding terrace and roof structures from various damages caused by extreme weather conditions, temperature fluctuations leading to expansion and contraction, abrasion, high and low-impact stressors, as well as corrosion.
Let’s explore the main causes of leakage and damage in Terrace and Roof Areas:
• Ponding on flat roofs.
• Separations from HVAC vibrations.
• Harsh weather conditions.
• Foot traffic and equipment movement.
• Worn-out roofs – rusting, cracked, peeling.
• Polyurea systems address all these challenges with their exceptional properties, making them a reliable choice for waterproofing and protecting terrace and roof areas.
The Top Benefits of Polyurea for Terrace and Roof Areas include:
1) Ultimate Waterproofing Protection: Once fully cured, Polyurea forms a seamless monolithic membrane that remains hydrostatically stable, ensuring no leaks due to the absence of seams.
2) Reliable Thermal Stability: Polyurea coating systems maintain their performance value and longevity despite varying weather conditions.
3) Exceptional Mechanical Properties: With an elongation of up to 1000%, Polyurea retains its elasticity even at temperatures as low as -40°C. It boasts high tensile strength, tear strength, abrasion resistance, and the ability to bridge cracks 1/8th of an inch or less.
4) Immediate Return to Service: Polyurea coatings cure within seconds, allowing for walkability within less than a minute, full curing in 24 hours, and immersion tolerance within 1-3 days. The fast and efficient coating process with Polyurea minimizes downtime.
5) Easy Application: Polyurea can be applied to virtually any architectural structure using a two-component high-pressure spraying equipment, simplifying treatment and waterproofing.
6) More than 10 Years of Warranty: The Polyurea coating system offers a warranty of more than 10 years, ensuring it will not delaminate or peel up, making it superior to warranties offered by other systems.
The incredible versatility of Polyurea makes it an ideal choice for Terrace, Industrial, and Commercial roofing applications.
In addition to the mentioned benefits, it exhibits excellent resistance to chemicals, making it suitable for complex detailing, offering slip resistance, surface textures, and enabling both vertical and horizontal application. Moreover, Polyurea is maintenance-free, boasts UV stable colors, and adheres excellently to concrete and metal even when damp. Notably, it can be applied in extremely low temperatures, as low as -30°C, making it a highly reliable all-weather solution. Additionally, being environmentally safe with no solvents and emissions, Polyurea reflects its eco-friendly attributes.
While other terrace and roof waterproofing solutions may have their merits, Polyurea stands out as an exceptional choice.
While Polyurethane systems may present comparable features from a technical standpoint, Polyurea outperforms them significantly, being like Polyurethane on Steroids.
Polyurea not only offers all the benefits of Polyurethane but also provides additional advantages, making it a superior waterproofing system.
For instance, Polyurethane roofs can be installed in half the time of traditional roofing systems, whereas Polyurea reduces installation time to a mere quarter.
Polyurea coating systems have undergone significant development over the past two decades, finding extensive use in the waterproofing industry for basement waterproofing, tanking, reservoir lining, roof and deck waterproofing, and concrete and steel protection, among other applications.
