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
