Practical Notes
! Commonly used for DPC (damp proof course) painting on masonry walls and as moisture barrier coating on underground GI pipes.
! Apply minimum 2 coats for effective moisture protection. Single coat provides minimal barrier.
! Not suitable for exposure to petroleum products or solvents — use epoxy-based coatings for chemical resistance.
! Surface must be clean, dry, and free of rust/loose paint before application.
