Waterproofing with polyurea: avoid infiltration and corrosion

Waterproofing with polyurea is a solution increasingly adopted by companies facing infiltration and corrosion in critical places. These problems cause structural failures that compromise durability, increase costs and require corrective downtime.

For those looking for technical performance and agility in execution, polyurea is an efficient technology, capable of protecting different surfaces even in harsh conditions. Find out more about its characteristics, applications and operational advantages.

What is polyurea waterproofing and how long does it last?

Polyurea is a high-performance elastomeric coating. Its main characteristics include: 

• High durability with low reduction in properties;
• High thickness in a single layer;
• Extra fast drying reaction;
• Insensitive to humidity.

The material is applied with a high-pressure spray, forming a continuous, elastic and resistant layer.

Polyurea waterproofing has a life expectancy of more than 10 years, reducing the need for corrective maintenance. This increases the time between interventions, benefiting the continuity of industrial processes.

How does polyurea help prevent infiltration and corrosion?

The main function of polyurea is to protect materials against water and chemical agents that favor deterioration over time. Understand how it works in engineering projects and industrial environments:

Efficient sealing even in critical areas

Spray application reaches corners, drains, joints and other hard-to-reach areas, forming a continuous and efficient barrier. The absence of gaps between layers reduces the chance of seepage.

Protection against aggressive agents

The composition of polyurea resists corrosive substances such as bases, solvents and acids. This prevents these agents from reaching the substrate, protecting the structure against corrosion - even in humid, aggressive or climate-changing environments.

In which situations is the use of polyurea most recommended?

Polyurea waterproofing can be applied to different types of work and sectors, especially when technical performance, safety and speed of execution are required. 

The application forms a uniform coating, without joints or overlaps, eliminating points vulnerable to infiltration. This provides sealing even in areas with irregular geometry.

Check out examples of elastomeric coating applications:

• Parts;
• Pipes and equipment;
• Slabs and floors with high technical requirements;
• Tanks and reactors with high-temperature immersion.

‍Whatoperational advantages does polyurea have over epoxy?

In addition to technical protection, waterproofing with polyurea also provides gains in productivity and efficiency when compared to systems such as epoxy paint. Check out this comparison!

Immediate application and release

The area treated with polyurea can be cleared for operation on the same day. Epoxy paint N-2680, for example, requires up to four days to fully cure - which represents a delay and an impact on the work schedule.

Savings on labor and equipment

Polyurea requires fewer steps, fewer professionals and less application time than epoxy. In addition, it does not require additional structures such as cranes and scaffolding, even in high areas - which can have a positive impact on the project's investment.

Less frequent interventions

Over a 10-year period, areas coated with epoxy will require, on average, 5 times more maintenance and costs. Polyurea, on the other hand, only requires one intervention, with fewer operational risks, less downtime and more safety for workers.

Stability in different climatic conditions

Polyurea waterproofing is insensitive to relative humidity. As long as it is not raining during application, the work can be carried out safely. Epoxy systems, on the other hand, are highly sensitive to the weather, requiring ideal conditions and waiting periods.

How to make the best decision when evaluating a polyurea solution?

The effectiveness of waterproofing depends not only on the formulation of the product, but also on the training of the team and the experience of the supplier. It is therefore essential to analyze technical criteria before choosing a solution:

Evaluate the product's formulation and performance

There are different types of polyurea on the market, with significant variations in composition. It is essential to choose products with proven performance, tested chemical resistance and the right formulation for the intended application - such as FCC's elastomeric coatings.

Look for experienced suppliers

The application requires qualified professionals, specific equipment and technical support at every stage of the project. Companies like FCC stand out for delivering complete solutions, with a track record of excellence and consultative assistance.
