Polyurea Coating Systems
Polyurea coating systems, while not exactly new, are gaining widespread acceptance in many applications. One of the areas that has seen a rapid growth in the use of polyurea coatings is commercial roofing. Unlike traditional roofing products, polyurea cures extremely rapidly. Therefore, facilities don’t have to be out of commission for extended periods of time while the roof coating dries. In fact, polyurea sets (cures) nearly immediately, often within 15 seconds or less. This typically means that the installation team can begin at one side of the roof and work their way across, with finished / dry coating before they reach the opposite side. Additionally, because it’s a sprayed on coating system, it can be applied in high build passes. This method results in a thicker, more durable coating for your roof.

Pre-Sprayed Panel Systems
Another remarkable benefit of polyurea systems is the ability to pre-spray large panels of geotextile fabric which can then be positioned together to form containments of virtually any size.
Each panel is manufactured with a 6 inch “seam” which is left un-sprayed. At the factory, all of the rest of the panel is robotically sprayed with our premium polyurea formulation. This method allows for very precise application of the polyurea coating.
Once these panels get on site, they can be unrolled and placed so the un-sprayed portion overlaps. Our crews then spray the exact same polyurea material over the ‘seams’, binding it all together. This turns the entire configuration into a singular, monolithic membrane. Because of the outstanding physical properties of polyurea, the pre-sprayed panels can withstand nearly every environmental factor that they encounter, making them perfect for rehabilitation projects, among others.
Direct Food Contact
When it comes to food processing, there are lots of regulations in place that help protect the public. Specifically, rules that mandate cleanliness and maintenance cycles are often most important. An added benefit when using polyurea protective coatings is that they are USDA approved (as well as other health-related organizations) for direct food contact. This means that food can come in contact with the coating itself and be just fine — there is no residue or outgassing that could contaminate the food itself.
Since polyurea is easily cleaned, and through its innate inert chemistry makes it very difficult for any types of bacteria to grow, it is the perfect choice for food processing plants.

Water & Power
In many industries, especially those integral to daily life like water and power, downtime for facilities can cause serious issues. Therefore, installing a protective coating system that can restore damaged infrastructure to serviceable status makes sense both financially as well as logistically. Combine that with the nearly immediate return-to-service capabilities of the polyurea technology, and it’s hard to imagine why you’d pick anything else as a solution.
Here at Meyer, we know that minimizing down time can be the deciding factor when trying to determine the best schedule for updating aging facilities. Use one of our premium polyurea formulations, and remove that factor from your plate. Pretty sure you’ll thank us for it.
