Polyurea History
Polyurea is a coating/lining technology and has been used very successfully for many different applications today around the world.
Polyurea by name is not a specific coating system or specification but is a description of a polymer technology with a huge range of product formulations offering a whole range of solutions. Almost no coating can compare to Polyurea when it comes to attainable physical properties from high elongation to superior tensile strength to hard or soft. Polyurea’s major benefit is its fast set return to service characteristics Tack free within 10 – 60 Seconds and open to traffic within the hour returning an area to service many times faster than traditional coatings.
Our Polyurea coatings are spray applied with a Graco HXP-2 Plural component system allowing us to fast apply with accuracy to any mil thickness, in one or multiple passes. Additional characteristics such as slip resistant textures can also be incorporated; UV stable colours can also be achieved.

For decades, traditional materials such as paint, epoxy, fibreglass and vinyl esters have all been used to perform these various types of protective coating applications.
Polyurea coating technology is not new. In fact it has been around and in use for almost three decades now. Polyurea is newer and more advanced than these traditional coating systems and offers many advantages to the owner, specifier and contractor.
Pipe / Pipeline Coatings & Linings
Polyurea Coatings and linings are increasingly being used to protect steel pipes from corrosion. Polyurea has demonstrated its ability to last longer than paint and maintenance services and costs are reduced. Polyurea is a great protective coating system for pipes that are insulated with polyurethane foam. Polyureas are also being used to line the inside of water and sewer pipes for infrastructure rehabilitation work.
Bridge Coating
Polyurea's ability to outlast paint and fight off corrosion is a major reason these systems are being specified for bridge deck and structure coating. The most common applications of polyurea coatings on bridges are over steel and concrete.
Tank Coatings
Polyurea coatings protect steel tanks from corrosion, chemicals, and other natural weather and jobsite elements. With proper surface preparation, substrate condition, formulation choice, primers, and installation procedures, polyurea goes on fast and stays on long. Polyureas are great for extending the life of older tanks and can offer limited structural characteristics as well. These systems can be applied during primary construction or in a retrofit environment. With their fast cure times they are ideal for retrofit since down time is significantly minimised compared to some competing materials.
Tank Linings
Polyurea linings are resistant to many chemicals and industrial liquids. With their fast application advantages and ability to adhere to properly prepared substrates, polyureas are ideal for new storage tank primary lining and rehabilitation projects.
Marine
Above the water line and below, Polyurea can be very effective in protecting steel, aluminium, and fibreglass in a variety of water sport and commercial marine applications. From sound attenuation for fishing canoes, to fish hold liners, to hull protection and bilge liners, polyureas are used in many abrasion, chemical and corrosion resistant marine applications.
Roof Coating
Polyurea coatings make an excellent protective covering for polyurethane foam roofs. Polyurea can be formulated to meet specific performance requirements due the wide range of physical properties that can be formulated. Some systems have the "Cool Roof" rating for colour and reflectivity. These reflective coatings can help reduce the amount energy consumption buildings use for heating and cooling. The fast cure time and insensitivity to moisture allows for a quicker installation with a wider application window. Proper surface preparation and substrate condition is always necessary.
Waste Water Treatment Linings
Fast cure, chemical and abrasion resistant, concrete primary and secondary containment linings.
Manhole & Sewer Linings
Polyurea manhole lining is a rapidly growing market due to polyurea’s ability to solve many current issues with groundwater infiltration and installation speed. Many municipal and private water systems are in great need of lining and structural repair. With proper surface preparation and substrate conditions, primers and Polyurea can be applied fast to return the cavity to service faster than most competitive systems. Polyurea’s ability to form a monolithic, durable liner protects the cavity from sediment and groundwater infiltration into municipal wastewater systems.
Flooring and Parking Decks
Polyurea flooring systems are most popular for their rapid turnaround installation capabilities. Other benefits are available with polyurea flooring systems as well. Polyureas are very durable and great for use in areas of high traffic. They are used in clean/dirty rooms as a waterproofing and protective coating from daily pressure cleaning operations. Polyurea can be formulated to be flexible and resilient allowing the flooring system to protect objects that may fall upon them.
Aquarium Lining
Aquariums have also found benefits with polyurea. The ability to form to properly prepared custom shaped walls and themed ornaments make this system desirable. A spray applied, water resistant liner, available in a variety of colours with rapid return to service installation is why facility owners are turning to polyurea.
Landscape & Water Containment
Landscape designers and contractors have found similar benefits with polyurea. Polyurea is often used to contain water for ponds and pool decorations to form a primary containment liner. Use of geotextile material is common when applying polyurea over dirt. Proper surface condition is vital when applying over concrete and most other substrates.
Water Parks & Playgrounds
Moulded slides, protective coating of seats for wet/dry amusement rides, tank linings, water containment, aquariums, concrete stadium seats are just a few of the many applications polyureas are commonly used for in the amusement and theme park industry. Polyureas usage is rapidly growing in applications to replace paint and fibreglass due its fast cure and ability to reduce maintenance cycles.
Railcar Lining & Track Containment
Polyureas are commonly used to line liquid containment railcars for their waterproofing and chemical resistance benefits. Hopper style rail cars have benefited from the strength of polyurea and its ability to resist abrasion. These cars often carry coal, sand, and other abrasive materials. Polyurea can be applied quickly and it will last longer than many other conventional systems if properly applied.
Fuel Storage & Containment
Polyurea is resistant to many fuels and chemicals. It is commonly used in fuel pits and pipeline secondary containment. Polyurea is not resistant to all chemicals and necessary compatibility tests and surface preparation are always required.
