Polyurea Spray Coating – Polyurea Coatings

Polyurea spray coating offers excellent protective qualities – ensuring your properties stay protected, warm, and dry.

Polyurethane Foam vs. Polyurea

Polyurethane and polyurea are both types of polymers – but there are some key differences between the two.

Polyurethane is created by mixing two or more components – typically a polyol and an isocyanate. When these components react, they form polyurethane. Known for its flexibility, abrasion resistance, and adhesion properties, polyurethane is a solid, durable material that can be used in coatings, adhesives, and foams. We often use polyurethane foam at NZAS as a flooring and roofing membrane.

    Product Description

    Polyurea, on the other hand, is created by mixing the isocyanate component with a resin blend instead of a polyol. When these components react, they form polyurea – a fast-curing, flexible coating that is great for waterproofing all sorts of materials, including concrete and steel.

    One of the main differences between polyurethane and polyurea is their curing time. Polyurethane typically has a longer curing time than polyurea – meaning it takes longer for the material to fully cure and harden. Polyurea, on the other hand, cures within a matter of seconds or minutes – ideal for fast-paced production environments.

    Another key difference between polyurethane and polyurea is the fact that they are applied very differently, drastically affecting the consistency of the final coating. While we apply polyurethane foam with a brush, spray gun or roller, we use a high-pressure spray gun for polyurea.

    Overall, both polyurethane and polyurea have their own unique properties and applications. Polyurethane is often used where flexibility and adhesion are important, while we go for polyurea when durability, chemical resistance, and waterproofing take precedence.

    Polyuera Spray Coating

    Polyurea is a versatile and highly durable coating solution that is becoming more and more popular. We use this coating for a wide range of our NZAS clients, including those in the automotive, construction, and manufacturing industries.

    Polyurea is great as a spray-on coating that is applied using a high-pressure spray gun. This coating is made by combining two liquid components: an isocyanate and a resin, which react with each other to form a tough and durable coating ideal for waterproofing.

    Let us tell you about a few of the advantages of polyurea coating.


    Well-known for its toughness, abrasion resistance, and ability to withstand extreme temperatures, polyurea is also highly resistant to chemicals, corrosion, and UV damage. For our clients looking for a solution that provides a high level of protection and durability, we almost always recommend polyurea. Additionally, polyurea has a longer lifespan than many other coating materials – providing long-lasting protection and helping reduce maintenance costs over time.


    Polyurea is a fast-curing coating solution that sets and hardens quickly upon application. Unlike traditional coatings, which can take hours or even days to fully cure, polyurea cures in a matter of seconds or minutes, depending on the formulation and environmental conditions. This fast-curing property makes this coating an ideal solution for fast-paced production environments, where downtime and delays are costly. The rapid curing process also allows for a more efficient application process, which can save time and labour costs. Overall, the fast-curing property of polyurea makes it a highly effective and efficient coating solution for a variety of industrial and commercial applications.

    Lots of Applications

    Polyurea is a versatile coating solution that can be used in a wide range of applications. Here are some of the most common uses of polyurea:

    1. Industrial flooring: We often use polyurea in industrial flooring applications due to the abrasion resistance, chemical resistance, and durability of the coatings.

    2. Waterproofing: Polyurea is an effective waterproofing solution, as it can create a seamless and impermeable barrier over a variety of surfaces, including roofs, foundations, and basements.

    3. Tank linings: Polyurea is one of the main spray coatings that we recommend to line tanks and other containers that store chemicals or other materials that can cause corrosion or contamination.

    4. Pipeline coatings: We use polyurea to coat pipelines and other infrastructure to protect against corrosion and damage from the elements.

    5. Bridge coatings: Polyurea is great for protecting and extending the lifespan of bridges, as they can withstand harsh environmental conditions and heavy traffic.

    6. Automotive coatings: Polyurea can be used in the automotive industry to provide a protective layer over vehicle components and equipment, including truck beds, bumpers, and undercarriage systems.

    Overall, the versatility and durability of polyurea make it an ideal solution for a wide range of protective coating applications.

    Better for the Environment

    Polyurea is a relatively environmentally friendly coating solution due to its unique properties and application process. First, polyurea does not contain any solvents or volatile organic compounds (VOCs), which are harmful to the environment and can cause health issues. This means that polyurea is non-toxic and safe for the environment.

    Second, polyurea coatings can be applied using a high-pressure spray gun – thereby producing very little waste and reducing the amount of material needed, compared to traditional coating methods. The lack of harmful chemicals and efficient application process make polyurea a more environmentally friendly coating option than many other types of coatings.
