Step One

Using a medium brush, apply the primer on the gate to prepare the metal prior to applying the colour paint you’ve chosen. Start on the side of the gate that is closed to you and work outside in before moving round to the other side.

Step Two

Smooth out any drips with your brush to ensure you create a clean finish.

Leave to dry completely and repeat process if another coat is required - although a good quality paint and primer should do the job in one.

To keep your brushes in the best condition, wash them straight after painting.


  • Keep your paint in a place that’s dry and clean and easily accessible if touch ups are required
  • Regularly wash down your gates and lookout for signs of chips that may cause rust
