Can I use plaster outside in Auckland?

Yes, plaster can be used outside in Auckland. However, it is important to consider certain factors and take appropriate measures to ensure its suitability and durability in outdoor applications. Here are some key considerations:

  1. Weather Resistance: Auckland experiences a moderate climate with varying weather conditions, including rainfall and temperature fluctuations. It is crucial to choose a plaster system that is specifically designed and suitable for exterior use. Exterior plastering systems typically have enhanced weather resistance properties to withstand moisture, UV radiation, and other environmental factors.
  1. Substrate Preparation: Proper preparation of the underlying substrate is essential for successful exterior plastering. The substrate should be clean, dry, and structurally sound. Any existing coatings, loose materials, or contaminants should be removed, and the surface should be appropriately primed or sealed to ensure good adhesion of the plaster.
  1. Moisture Management: Adequate moisture management is crucial for exterior plastering. Waterproofing measures, such as the use of suitable membranes, flashings, and sealants, should be implemented at vulnerable areas like windows, doors, and junctions. Proper drainage systems should also be in place to prevent water accumulation behind the plaster layer.
  1. Ventilation: Ventilation is important to allow moisture to escape from behind the plaster and prevent the buildup of moisture that can lead to problems such as mold growth or deterioration. Ventilation details, such as weep holes or breathable membranes, should be incorporated into the plaster system as needed.
  1. Maintenance: Regular maintenance is essential for the longevity of exterior plaster. Periodic inspections should be conducted to identify any cracks, damages, or areas that require repair. Prompt repairs should be carried out to prevent water ingress and further deterioration.
