In polyurea roof coating, liquid waterproofing products have been rising in popularity over the last number of years, and polyurea is leading the pack. It offers a host of advantages over other traditional roofing materials, including being able to be applied directly to an existing roof. This means that there are no roof cutters, prying tools, and hot asphalt to be handled, lowering the risks associated with roofing significantly.

Its elastomeric nature allows it to offer exceptional tensile strength, elasticity, and chemical resistance, making it highly durable and resistant to impact damage. It is also able to bond with a range of substrates, such as concrete, metal, and spray polyurethane foam.

The material can be customised with different physical properties to suit specific applications, and it is available in a range of colours. It can also be applied in a wide range of temperatures and humidity levels, and it performs just as well indoors as it does outdoors.

Upfront Expenditure: Due to its specialised equipment and application process, polyurea is more expensive than other coating methods. This upfront expenditure encapsulates the cost of professional service fees and the utilisation of specialised spray rigs that are engineered to manage the two-component system, combining them at the nozzle only at the moment of application.

The speed of curing is another factor that contributes to the increased demand for polyurea, as it can be used on projects with tight deadlines and can be touch-ready almost instantaneously after being applied. Its rapid internal curing can also help with managing moisture sensitivity in humid environments and on surfaces prone to condensation.
