Drying and Curing Time

  • Touch Dry: 20 minutes
  • Hard Dry: 1 hour
  • Full Cure: 2 hours – force dry at 60-100°C for 20 minutes
  • Re-coatable: 30 minutes

Drying times are based on temperatures of 20°C, lower temperatures will increase drying times. Please speak with our technical team before elevating temperatures or attempting to force cure any of our products unless already stated. Shop conditions such as having good airflow will optimise curing.



Suitable to be overcoated with most single pack products including Guard FEB and Guard SPU topcoats, or onecoat products such as Guard SCF for greater corrosion protection.


Surface Preparation

  • Ensure surfaces are clean, dry and free from grease and other contamination before coating
  • Thoroughly degrease and where applicable, abrade to remove rust and promote good adhesion of the coating
  • For optimum corrosion protection, mild steel should be blast cleaned to Sa2.5
  • Complex structures may be more effectively cleaned by HPWJ (high pressure water jetting)
