Recommendations for use

  • The coating can be applied by a brush, or spray
  • The coating must be stirred well before use
  • The coating can be diluted with water till required consistency before use
  • The coating must be applied to a clean from dust and oil surface
  • In order to avoid cracking and to provide the best adhesion, t he coating is to be applied with a thin covering layer
  • Application on a heated surface (up to 150 C) improves the result and reduces the drying time
  • When necessary, the material is reapplied to ensure proper covering
  • The covering must dry before use
  • Brushes and other tools can be cleaned with water after use
