The Benefits of Exterior Plaster for New Zealand Homes

Published on
May 14, 2025

If you are a homeowner in New Zealand and you are building or renovating, you will need to consider building materials that will stand the test of time. Materials should be durable and pleasing to the eye, whilst having capacity to withstand our country’s extreme and varied weather conditions. 

Plaster has been a durable and aesthetic material for internal and external building projects since it was first recorded and used in Ancient Turkey in 12,000 BC. 

Exterior plaster is known to deliver strength, supply insulation, and a sleek look for both residential and commercial properties across the world.

Whether you’re building a brand new home or maintaining your existing one, understanding the benefits of exterior plaster can help you make an informed decision for the best building materials to choose for your project.

Durability: Exterior Plaster Homes Built to Withstand New Zealand’s Climate

As kiwis, we know that New Zealand’s climate can vary wildly. From sticky, humid coastal regions to crisper, colder inland areas. Home exteriors must be designed to withstand a range of conditions, from moisture, sudden temperature changes as well as prolonged exposure to harsh UV rays. Exterior plaster can offer your home strength and durability, providing a protective layer that safeguards walls from environmental damage. Exterior plaster is known to  prevent water ingress and minimises common kiwi building moisture-related problems such as mould and rot, which can be detrimental to your families’ health. 

Impact resistance can be another benefit to exterior plastering, as unlike traditional wooden style cladding, plastered surfaces have a tough and resilient finish that can withstand minor impacts and general wear and tear.

High-quality exterior plaster can provide longevity as when it is properly maintained, can last for decades with minimal maintenance, making it a cost-effective solution for homeowners.

With the right application and care by experienced professionals, exterior plaster strengthens the home’s structure and can preserve its appearance over time.

Weatherproofing: Protection from the Elements

Heavy rainfall, high humidity, and strong winds are extreme weather conditions, homes in these regions require adequate weatherproofing. Exterior plaster acts as a barrier against external elements providing insulation to regulate indoor temperatures and improving energy efficiency. In a cost of living crisis, keeping power bills down is a welcomed bonus. 

For homes in coastal areas like Auckland, where salt-laden air can contribute to material deterioration, exterior plaster offers additional protection by minimising the impact of airborne contaminants.

Exterior plaster formulations have evolved significantly since 12,000 BC and now can have  water-repellent coatings incorporated, which further prevent moisture infiltration. This added layer of protection can ensure your walls remain dry and damage-free for generations to come.

Aesthetic Appeal: Enhancing Home Design

When building or renovating, your home’s visual appeal is a key consideration for both homeowners and property investors. Whether you prefer a classic smooth finish or a more rustic textured and decorative surface, exterior plaster provides a variety of design options.

Plaster Customisation Options

With dozens of plaster styles and finishes available, homeowners can tailor to their architectural style. Smooth plaster coats are ideal for urban, modern home designs, displaying a sleek and polished appearance. Textured plaster finishes can add depth and character, providing a unique appearance. These looks can then be painted to achieve any unique style required. For those who want a low maintenance home, coloured plastering can be a winning choice. Coloured plaster can eliminate the need for external painting by incorporating pigments into the plaster formula. 

Increasing Your Property Value

As many Real Estate agents will agree, homes with high-quality exterior plaster finishes tend to command higher property sale values. This is due to their durable, sophisticated appearance. Whether preparing a home for resale or upgrading for personal satisfaction, investing in professional plaster application enhances street appeal and buyer demand.
