Base Material: Cement base material needs to be fully polished, remove surface oil, dust, and floating ash to expose the cement structure layer. Steel substrate requires sandblasting to remove dirt and rust. Roughen the steel surface to ensure sufficient physical riveting points between the Primer and the substrate.
Primer: Polyurea enterprises have special primers, such as epoxy systems. Ensure the primer adheres well to both the substrate surface and the Polyurea Coating. The surface drying time and physical properties of the primer significantly influence spray polyurea construction.
Polyurea: Different spraying polyurea options are available according to specific applications.
