Polyurea is truly a remarkable coating that can be applied at temperatures ranging from minus 20 Degrees fahrenheit all the way to 200 Degrees Fahrenheit.
When applied with a secondary geotextile fabric, Polyurea can have a tensile strength of over 4500 PSI. Once you consider that Polyurea Coatings have an elogation propensity of over 500 percent, other coatings such as fiberglass reisins and epoxies can't compare.
Take a look at the Blast Mitigation Video below and the effects on a cinder block wall that was coated with Polyurea and then a control wall with no coatings at all. The wall that had Geotextile Fabric and Polyurea actually expanded outward during the explosion over 9 ft and then back to its original form, while the control wall was simply obliterated.
