  • 1 Clean the shed to remove dirt, dust and debris. Remove any dirt, moss, fungal growth and lichens with a stiff brush. Wear a suitable face mask when sanding to avoid the inhalation of dust.
  • 2 Mask any hinges or windows on the shed to avoide damage from paint. Lay down dust sheets under the area you will be working to avoid any paint splattering on the ground.
  • 3 If using a brush, paint the shed in sections. Cut in around any doors/windows/edges first and then paint the main areas, applying the paint in the direction of the grain.
  • 4 A time saving option is to use a paint sprayer. Pour the sprayable product into the tank of the sprayer and then secure the clips.
  • 5 Turn it on and stand about 20cm back from the shed. Gently squeeze the trigger to start the sprayer.
  • 6 Spray the shed using the same method as if you were using a brush – cut in around any doors/windows/edges first and then spray the rest of the shed, working in sections and spraying from top to bottom. Don’t spray on a windy day as it may drift to an adjacent garden.
  • 7 Leave paint to dry for time indicated in manufacturer’s instructions and apply a second coat if necessary.
  • 8 Remove any dust sheets/newspaper/masking tape from the area you were working in. Finally, use an exterior metal paint on any hinges or locks to complete the job.
  • 9 Now your timber shed is completely painted
