Intergard 269 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2L for underwater hull/boottop or HB2M for above water areas. Minor areas may be prepared by power tooling to Pt3 (JSRA SPSS:1984)

As a Tie Coat over Zinc Primers

The primer surface should be clean, dry and free from all contamination. Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa2½ (ISO 8501-1:2007)).
