What are the disadvantages of plastering walls?
Plastering walls in Auckland suburbs can present some specific disadvantages and challenges. While these issues may not be limited to specific areas, certain factors can contribute to their prominence. Here are some common disadvantages of plastering walls in Auckland suburbs:
- Moisture and Humidity: Auckland’s climate, with its high humidity levels and occasional heavy rainfall, can pose challenges for plastered walls. Excessive moisture or prolonged exposure to humidity can lead to plaster deterioration, cracking, and the growth of mold or mildew. Suburbs near the coast or areas with inadequate ventilation may be more susceptible to these issues.
- Subsidence and Movement: Some Auckland suburbs, particularly those with varying soil conditions, may experience ground movement or subsidence over time. This movement can exert stress on plastered walls, leading to cracking or uneven surfaces. Suburbs with known ground instability or areas with expansive clay soils may be more prone to these issues.
- Earthquake Vulnerability: Auckland sits in an active seismic zone, which means it is susceptible to earthquakes. Plastered walls may be more vulnerable to damage during seismic events compared to other construction methods, such as lightweight framing with flexible wallboard systems. Areas with higher seismic activity or closer proximity to fault lines may face greater risks.
- Retrofitting Challenges: Retrofitting older properties in Auckland suburbs with plastered walls can present additional difficulties. These properties may have existing layers of plaster that need repair or removal, which can be time-consuming and costly. Retrofitting insulation or upgrading electrical and plumbing systems within plastered walls can also be more complex compared to alternative wall finishes.
It’s important to note that the disadvantages mentioned above are not exclusive to specific Auckland suburbs. They can be encountered in various areas, depending on factors such as climate, soil conditions, and the age of properties. Assessing the specific characteristics of your property, consulting with professionals, and implementing appropriate moisture control measures can help mitigate these disadvantages and ensure the longevity and durability of plastered walls in Auckland suburbs.
