In today’s fast-paced commercial construction landscape, polyurea and polyurethane-based deck coating systems have become indispensable for their exceptional combination of durability, flexibility, and performance. Designed to help protect surfaces against vehicular and pedestrian traffic and challenging environmental conditions, these advanced coatings offer a long-lasting solution for protecting vital structural elements.

Their technical advantages, including advanced durability and protection, make them a strategic investment for architects, contractors, and building owners looking to enhance both performance and lifecycle value.

Engineered to meet the demands of modern commercial buildings, these coatings are ideally suited for applications such as lower decks, intermediate parking garages, parking spaces, and for surfaces outside of trafficable areas, such as balconies.
Their ability to adapt to structural movement while maintaining a seamless, watertight barrier helps ensure long-term concrete protection and aesthetic integrity. As performance expectations and environmental standards continue to rise, polyurea and polyurethane-based systems offer a forward-thinking approach to protecting valuable structural assets and potentially reducing lifecycle maintenance costs.

Performance Characteristics
The technical benefits of polyurethane and polyurea-based solutions apply for a range of commercial building challenges. This is due to several characteristics, including protection against chemicals, abrasion, and ultraviolet (UV) stability.
Commercial buildings can encounter exposure to harsh chemicals, from automotive fluids in parking areas to cleaning agents in public spaces. What distinguishes a polyurea-based system is its remarkable ability to withstand prolonged contact with these substances without degradation, tested in accordance with ASTM E303. This resilience translates to reduced maintenance needs and extended lifespan for commercial structures.†

Some waterproofing membranes degrade when exposed to prolonged sunlight, which can lead to premature aging, cracking, and costly replacements.† Polyurethane- and polyurea-based systems, such as Siplast’s Terapro PUR, are formulated to withstand intense UV radiation without significant deterioration.

This UV resistance makes them ideal for exposed applications, including balconies, terraces, and walkways. When used in conjunction with epoxy primers, Terapro PUR can serve as a durable top coat, enhancing overall system performance and longevity in UV-exposed environments.

The chemistry of PUR-based systems allow them to adhere to a variety of surfaces.

Areas experiencing high foot or vehicular traffic require exceptional durability from their protective coatings.† Poorly-manufactured materials can often lead to costly repairs, replacement, and downtime, making long-term durability essential.

This property makes it particularly beneficial for many exterior applications, including parking structures, high-traffic balconies, and more.
When applied to surfaces, the liquid, synthetic polymers of polyurethane-based deck coatings form a protective barrier, offering long-term protection against water and weathering. Furthermore, the inherent flexibility of the chemistry allows it to adhere to a variety of surfaces.
Polyurea and polyurethane-based products can be modified for a variety of surfacing and color finishes, contributing to the desired aesthetic of any project. Additionally, its skid resistance, in accordance with ASTM E303, helps maintain a clean finish.

Benefits for Industry Professionals
The technical sophistication of today’s building landscape requires professionals to navigate projects with efficiency and reliability. Consultants, for instance, must be knowledgeable and recommend materials with proven performance across multiple parameters. By recommending systems with demonstrated longevity and performance from trusted providers with a proven history, such as Siplast, consultants can enhance their professional reputation while delivering genuine value to their clients and reducing building disruption.
For building owners, polyurea and polyurethane-based deck coating systems offer an economic advantage with a high return on investment. The material’s extended service life and minimal maintenance requirements may potentially provide savings. It’s important to remember that the initial installation cost represents only a part of the true lifetime expense of waterproofing systems. Replacement, repair, and associated disruption often constitute the major expense over a building’s lifespan.

Meanwhile, architects may prioritize materials that balance durability and function with aesthetics. Terapro PUR’s versatility accommodates designers’ creative design solutions without compromising performance or waterproofing concrete protection.

Real-World Applications
To get a better idea of use cases, polyurea and polyurethane-based systems are ideal for commercial surfacing such as parking structures, rooftop decks, balconies, industrial facilities, and more.

Parking facilities present multiple challenges for waterproofing materials — constant vehicle movement, tire abrasion, exposure to automotive fluids, and often extreme temperature variations. Terapro PUR’s durability makes it exceptionally suited for these environments.
Outdoor amenity spaces, especially building rooftops, have grown increasingly popular for commercial buildings, providing tenants with outdoor environments for leisure or gatherings. These areas must withstand UV exposure, rain, challenging temperature extremes, and ongoing foot traffic while still maintaining an attractive appearance. Terapro PUR’s UV stability and weather resistance help preserve aesthetics and protect the underlying structure over time.

Balconies and other projecting elements face similar challenges as they are exposed to environmental stresses from multiple directions and must endure frequent foot traffic.† Terapro PUR’s protection against abrasion resistance and flexibility provides the necessary protection to withstand these elements.

Industrial facilities often present an even more challenging environment, combining heavy mechanical stress with exposure to aggressive chemicals. Terapro PUR’s protection against chemical and abrasion resistance helps provide lasting protection even under harsh manufacturing conditions.†

Conclusion
As construction technology and building expectations evolve, traffic coating solutions must advance to meet increasingly complex performance requirements. Polyurethane and polyurea-based deck coating systems offer a durable, versatile, and efficient solution for commercial building challenges. Their technical advantages make them a strategic choice for enhancing the performance and longevity of commercial structures.

By investing in these advanced coating systems, building owners can ensure their properties are well-protected and built to endure. This investment delivers immediate functional benefits while also supporting long-term savings and sustainability, making polyurea and polyurethane-based systems a smart choice for any commercial building project. 
