Technical Datasheet
Advantages
  • Easy to apply
  • Increases the protect of steel against corrosion
  • Maybe overcoated
  • Economical
Surface Preparation
Iron or steel surfaces should be free of loose rust. Exposed metal should be thoroughly wire-brushed to obtain a clean state. Galvanised steel should be degreased and completely free of white rust and adhesion preventative compounds.
Mixing
Stir well before use.
Coverage

Practical coverage for estimating purposes: 12 m2/litre

Application
4 metal primer may be applied by brush or roller straight from the tin; for spray application thinning with up to 10% water may be necessary.
Overcoating
4 metal primer must be overcoated with water-based acrylics, or alkyd enamels.
Cleaning
Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.
