Apply by brush or conventional spray. 

Preparation

Surfaces to be coated must be clean, dry and free from any material such as oil, grease, salts and dirt that might affect adhesion.

Remove loose flaking or friable material. 

Where necessary, remove weld spatter and grind smooth all rough,sharp edges and weld seams.

Galvanised steel

Thoroughly degrease with Cleaner Degreaser (Product Reference H30 or ND14) and lightly abrade any very shiny areas. 

Mild Steel 

Degrease with a Cleaner Degreaser (Product Reference H30 or ND14) and either manually abrade or blast clean to Sa2½ (ISO 8501-1:2007)

If blast cleaning is not possible, phosphating is recommended for cold rolled steel to improve adhesion.

Phosphate Steel 

Degrease with Cleaner Degreaser (Product Reference H30 or ND14) and manually abrade prior to application of the Primer/Finish Coat.

Stainless Steel

Degrease with Cleaner Degreaser (Product Reference H30 or ND14) and manually abrade prior to application of the Primer/Finish Coat.

Aluminium and Alloys

Degrease with Cleaner Degreaser (Product Reference H30 or ND14) and manually abrade prior to application of the Primer/Finish Coat.

The temperature of the ambient air, surface or paint should not fall below 5ºC during application or drying.
