Use guidance

From selection
to application.

Application

Applied with a single component injection pump into the prepared pakers (injectors). The application pressure varies between 14 and 200 bars. Application should begin with the first paker (injector). A starting at low, the pressure is increased until resin overflows. When the resin overflows, the application moves on to the next paker (injector). During the injection application the resin that is injected from all pakers (injectors) will begin overflowing from the cracks on the concrete. After this procedure, the application is finalized. In the application of YAPIFINE SERUM, the consumption amount is proportional to the cracks and holes that need to be completely filled.
