Application Method
The application was performed in accordance with modified Belzona system leaflet VPF-8. Firstly we made the test with Belzona 1221 application on the small area of this bend. Adhesion was perfect. Then we started to repair the entire crack. We terminated the crack by drilling 6 mm hole at the end to prevent further propagation, "veed" out crack with a hand held machine, then roughened it using the Belzona roughing brush.  After chemical cleaning was Belzona 1221 applied.
