Polyurea stems from the Polyurethane group and is notably versatile; known for its superior adhesion, abrasion resistance and ability to fight corrosive material, as well as it powerful, long-lasting coating, waterproofing aptitudes and amazingly fast cure time. Polyurea is the leading solution in protective coatings.
Polyurea is an exemplary coating, sturdy sufficient for substantial performance in commercial applications. It is very intricate and unyielding to most elements. We spray 100% Polyurea with a high pressure, high-temperature method. It hardens in fewer than 10-15 seconds, so you get a uniform, high-quality grain industry polished look. We can further add extra texture for a traction-enhanced surface to high traffic areas, walkways, guards, stairs, and any other areas that may need to be skid proof.
Polyurea is exceptionally tough & repellent to chemicals, it is perfect for super duty tasks! Whether you are looking to defend against rust & corrosion, need a non-skid coating or want a robust, durable emergency coating, Polyurea is more than suitable the answer for you.

The latest coating technology is polyurea. Developed throughout the late 1980s for the automotive business, this material is immediately employed in a wide array of purposes. Use of this material as technical waterproofing has skyrocketed in the industry in the past decade due to its fast-curing, corrosion- and abrasion-resistant qualities.
Hank S., director of business development and training at ArmorThane Corporation, describes, “Polyurea was invented in the early 1980s when a less moisture-sensitive class of polyurethane was wanted. By replacing the hydroxyl group in the urethane with an amine group, a product we now call polyurea was created. It has significantly less responsiveness to moisture than different urethane-based coatings.”
Of the two most popular kinds of polyureas, aromatic polyureas are by far the most popular. Phelan calls them “the workhorse of the business offering a wide variety of engineering characteristics for various purposes.” In fact, about the only aspect, these coatings do not provide is UV stability.
A second formulation, aliphatic polyureas, use complex chemistry to produce UV resistance. This added advantage begins at a price as aliphatic polyureas are typical twice the rate of aromatic polyureas.
Advantages Of Polyurea
One reason polyurea coatings are booming in popularity is the wide variety of definite attributes they exhibit.
The industry website, polyurea.com, opens with a bold statement. “Virtually no other coating can compare to polyurea when it comes to attainable physical parts,” it reads. “Polyureas can be formed to achieve a tremendous spectrum of resources from high elongation to superior tensile force to hard or soft, all based on how the materials is formed and correctly applied.”
It adheres tenaciously to a modification of different substrates (cement, elements, lumber and more) without primers and in a wide range of fire and moisture conditions.
Conceivably its most notable benefit is that it sets up remarkably quickly, enabling the applicator to build up a finished thickness in a single pass. This allows the owner to put the plant back in service several times quicker than conventional coatings, accumulating days or even weeks of revenue failed to fluff-time.
Phelan says, “Depths can range from 20 mils to 500 mils in one form. Cure sponsors range from instantaneous to two minutes allowing for a quick return to duty.”
As fast curing, thick layer coating, polyurea is a logical purpose when seamless, durable membranes endure needed for waterproofing. Additional characteristics such as slip-resistant additives and surface forms can also be consolidated. It can be distorted and is even available in a pure-water-approved formulation.
With such a wide range of performance characteristics, the scope of suitable applications is also significant. Tank reinforcements, secondary containment, and bridge coatings are some of the most common uses, but the application possibilities are endless.
The technology has been employed successfully on pedestrian decks and parking garages, tanks, tunnels, rain tanks, slurry pits, and flooring. It can also be formed as a joint filler/caulk.
Polyurea was originally operated as a truck bed liner to form a permanent watertight layer. The same old and abrasive-resistant characteristics that make it perfect for lining truck beds and dump trucks make it attractive for complex waterproofing projects.
The containers at wastewater processing plants, for example, are exposed to erosion, and massive amounts of hydrogen sulfide gas when the contents are veiled, mixed and dewatered.
Polyurea coatings can supply the abrasion, chemical, and impact protection needed, and restore the plant to operating condition faster than many other competing systems.
Polyurea does have a few drawbacks. The equipment required to utilize polyurea coatings can be expensive for one. It can range from $5,000 to $50,000 or more. Fully equipped mobile platforms can cost upwards of $100,000.
The chemical also costs more than some alternatives. The initial costs are greater than epoxies, but since polyurea coatings can last three to five times longer, it becomes considerably more cost-effective over the lifetime of the surface.
As with any waterproofing substance, it can collapse if applied inappropriately. Surface preparation —usually sandblasting or priming—is crucial for a successful application. Most failed polyurea coating projects have little to do with the polyurea itself, but rather, inadequate or poorly implemented exterior preparation.
Most polyureas used for waterproofing are spray-applied with plural component spray equipment.
It’s typically transported as a two-part operation, with the amine resin blend and isocyanate material supplied in 55-gallon drum sets. Once in use on the project site, they are transported from 55-gallon drums to separate containers in the spray machine where they are cooked to the appropriate temperature (140°F-160°F). The device then delivers the isocyanate and polyol resin through heated lines to the spray gun in a precise ratio (usually 1:1).
Polyurea has a set time that is estimated in seconds, so it’s crucial that the chemicals don’t mix until the instant before they leave the gun. Otherwise, the compound will set and harden inside of the spray gun.
Several businesses sell mobile spray rigs that include all of the tools and equipment needed, mounted on either a trailer or truck bed.
