Standard Pure Polyurea, is a very fast set, 2-component, 100% solid flexible coating derived from a reaction of an isocyanate prepolymer and an amine terminated resin blend. This general purpose aromatic pure polyurea has been especially designed to protect and coat concrete, metal, wood, ceramic, geotextile surfaces. The product reacts within seconds and once cured, leaves a flexible, durable, tough surface. Its extremely fast gel time makes it suitable for applications down to -20 °C without special conditioning of the component resins and isocyanates. It is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions. The material must be applied utilizing high pressure, heated plural component spray proportioning equipment.

- Surface preparation strongly affect coating performance. Concrete substrates must be prepared mechanically using abrasive blast cleaning to remove cement laitance and achieve an open textured surface. Weak concrete must be removed and surface defects such as voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products . The application surface has to be primed in order to achieve an even surface and good adhesion.
- All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. For application pull off strength of the surface should be min. 1.5 N/mm² and concrete residual moisture should be max. 6 %.
- Isocyanate prepolimer and amine resin must be applied using a 2-component high pressure spray machine.
- Amin component must be stirred using a barrel mixer.
