Regularly check and clear debris from the inside of your spouting.
Check brackets are intact, spaced max 500mm apart and spouting has even fall towards outlet to avoid water ponding. (Min 5mm per 10m)
Unclip 2-part expansion joiner, clean the rubber seal of any dirt or grit and re-lubricate with a silicone based lubricant before reassembly.
Wash your Marley spouting system annually using warm soapy water and a soft bristled brush or cloth. Rinse with clean water.
Clean spouting and allow to dry. Apply mineral-based undercoat and two coats of acrylic paint.
N.B Do not paint inside of spouting or brackets, darker colours require additional expansion allowance.
