Surface must be dry, clean, firm and free from oil, grease, dust and other surface contaminants.

Ensure that surface is clean and rust free before priming. Use abrasive blasting to Sa2 minimum to remove rust and mill scale. Not recommended that hand cleaning is used.

Galvanised Iron
Clean surface with an abrasive cleaner, as per manufacturer’s recommendations.

Other surfaces

All loose materials must be removed and degrease substrate with Top Paints’ Degreaser and scouring pads. Rinse with clean water until water break-free film is achieved. Leave to dry.

Previously Painted Surfaces

Use most suitable method, as stated above, to clean back to sound substrate. Test area to ensure that existing paint will not lift. Blast or strip off if lift occurs.
