4. BREAKING OUT

Remove contaminated concrete, exposing rear face of any steel uncovered.

 

 

 

5. FULLY EXPOSED STEEL

Further break out may be required to reach clean, uncorroded steel.

 

 

 

6. CLEAN REINFORCEMENT

Steel bars must be cleaned to bright condition - special attention to rear faces.

 

 

 

7. CLEAN THE SUBSTRATE

Remove final traces of contamination and roughen edges to provide a ‘key’

8. PRIME REINFORCEMENT

Apply one full, unbroken coat of EPOZINC / BETOFER and allow to dry.

 

 

 

9. ERECT SHUTTER

Fully sealed, grout-tight shutter needed with drainage & air vents.

 

 

 

10. PRIMING THE SUBSTRATE

Saturate substrate several hours prior to placement of BETOCEM MC / BETOCEM FLOW.
