Surface Preparation:

The surface shall be solid, clean, dry, and free of any hydrocarbon residuals. The surface must be sanded with a grinder.


For each application a dew point distance of 3°C must be observed.


Reprofiling. Cover the cracks and uneven surfaces with EPOFLEX® Klebmoertel. For application use spatula or comb.


The laminate system is a 2-component epoxy-based laminate resin and a special woven ultra high strength fiberglass sheet. The laminate can be applied in 1, 2, or even 3 layers up to the damage and the customers’ demand. For laminate, the application uses a roller and previously cut fiberglass sheets.

Tightness Test:

After patch repairing the tightness of the tank must be tested.

Installation note:

The above information is based on tests by approved institutes (e.g. TÜV Süd Germany) and many years of experience. As the lining performance depends on correct installation, we offer application courses for certified installers and installation supervisors and provide certificates which shall be renewed every 3 years.
