Single-Pack, Water-Based Metal Etch Primer. 

4 metal primer is a water-based acrylic resin with acid etchant and corrosion inhibitive pigments.

As a corrosion inhibitor on clean iron and steel such as gates, fences, garden furniture, air-conditioning units and galvanised surfaces.

Easy to apply.
Increases the protect of steel against corrosion.
Maybe overcoated.
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.
Stir well before use.

Practical coverage for estimating purposes: 12 m2/litre

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.
4 metal primer must be overcoated with water-based acrylics, or alkyd enamels.
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.
