Surface Preparation:

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

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

Levelling:

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

Laminate:

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

Thigness Test:

After this patch repair 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.
