Application and Features

  • "GF-021" priming is designed for priming metal, wooden and concrete surfaces.
  • Dry coating is highly resistant to grit and ultraviolet rays. Can be applied both as priming layer in coating systems and as independent coating.
  • Film is tolerant to temperature drops withing the limits of -45 - +60°C.
  • Priming is highly adhesive to metal, wooden and concrete surfaces exposed to drastically changeable atmospheric conditions.
  • Priming is applied by any way of spraying, by a roller or brush, by dipping or jet-stream spilling.
  • Color - red-brown, gray.

Instructions for use

Before applying priming stir it until it becomes smooth paste. After a durative storage, an insignificant exfoliation is possible. For less viscose priming, dilute it with 646 dissolvent, or with solvent, or with White Spirit until desired thickness is obtained.
Priming is applied to dry clean surface under at least 5 °С and humidity no higher than 80%. When applying priming, surface must be at least 3°С warmer than dew point.
This priming is compatible with hot drying (105-110°C, 1 hour).
