HOW TO Mix Cobra Coatings and Hardeners

HOW TO Mix Cobra Coatings and Hardeners

  • The standard mixing ratio for Cobra is typically 3 parts Cobra coating to 1 part hardener. However, always refer to the specific product's technical datasheet for exact ratios.
  • Do not alter the mixing ratio to speed up drying time. Mixing ratios are specifically designed to ensure proper curing and performance. Altering them can compromise the durability and effectiveness of the coating.
  • Make sure you shake the bottle (if using Cobra spray gun) or the mixing cup well before applying. We recommend 2 minutes.
  • Once mixed, Cobra has a pot life (usable working time) of about 60 minutes at 20°C (68°F). After this time, the mixture will begin to harden and become unusable. Only mix as much as you can use within this timeframe.
  • Using the wrong mixing ratio can lead to several issues, including improper curing, reduced durability, poor adhesion, and an uneven finish. Always follow the recommended mixing ratios for optimal results.
