- The first step is to prepare the support by mechanical cleaning.
- Infiltrations must be stopped before further treatment.
- Gaps or holes in the concrete surface must be filled and smoothed with reprofiling mortar.
- The support is then primed with eproPrim E.
- The coating process is as follows:
A polyurea-based ambient-cure two-component coating is applied to the surface to be repaired. The highly reactive liquid components are processed by a specifically heated high-pressure two-component airless spray gun.
The components are mixed at a predefined ratio (1:1 by volume) and sprayed at high pressure onto the surfaces to be repaired. They react within seconds. This is true not only for “normal” temperatures, but also for applications at temperatures below 0°C, where other systems tend to fail.
- The coating requires visual inspection. It must have a homogenous overall appearance without any voids, bubbles and/or inclusions.
- The adhesive strength shall be tested with a hydraulic pull-off tester in accordance with DIN EN (ISO) 4624.
The excellent properties of the liquid components allow even difficult geometries to be easily coated.
The application is extremely efficient due to the high flow rate.
Thanks to their high humidity tolerance, eproCoat SB and eproCoat SBA can be applied even in most difficult conditions.
SprayCoating with eproCoat SB and eproCoat SBA (antistatic) is optimally suited for the repair of manholes, settlement tanks, concrete structures, man-entry pipe systems, tunnels and steel structures.
