Then the 1st layer of Belzona 5891 was applied at a thickness of 300-400 microns. After the initial mechanical stability of Belzona 5891, brush-off blast cleaning was carried out and the 2nd layer of Belzona 5891 was applied at a thickness of 300-400 microns. In the straight sections, the coating of Belzona 5891 was applied.
