Application Situation

The aluminum shield on the clarifier extends 16 inches below the water line. This is the only one serving this small city.

Application Method

Abraded new aluminum panels and coated with Belzona® 3921 and Belzona® 5811 in accordance with Belzona Know-How System Leaflet TCC-5. The panels were then bolted to the sound skirt eliminating need for complete replacement.

Belzona Facts

The city did this repair using $500 of Belzona and $1,000 in metal and supplies. It also took them only 1 day versus more than a week to replace the whole shield.
