When it comes to exterior finishes for your home, there are a plethora of choices; traditional weatherboard, stone veneer, metal or vinyl cladding, concrete panels, fibre cement sheets, brick and block, or timeless and versatile exterior plaster. Each of these building materials carries their own pros, cons, strengths and appeal, as well as budget.  

However, as seasoned, Licensed Building Practitioners who have practiced the art of plastering for over 100 years throughout the West Family Dynasty, modestly speaking, we know all there is to know about plaster. 

Not only will it upgrade the appearance of your home, it will also provide a protective shield against environmental elements, which we all know is critical in New Zealand’s interchangeable weather and coastal properties.  At West & Sons Construction, as seasoned plaster craftsmen, we understand the importance of high-quality solutions that deliver top notch functionality and style.  So, without further ado, let’s explore the benefits of exterior plaster for your home. 

Elevate Your Home’s Exterior

One of the more prominent and immediate benefits of exterior plastering is its ability to completely visually transform the look of a home. It can provide a polished look, making it a superior choice of exterior building materials. Whether you prefer a smooth, modern finish or a textured, rustic appearance, plastering offers a range of looks and possibilities.  

Versatile Finishes

Exterior plaster can be customised to suit various architectural styles, from modern and contemporary homes to classic designs or texturised rustic charm.  

Seamless and Polished Appearance

Unlike the more fragmented look of brick or timber cladding, smooth plaster can create a sleek, uniform and elegant surface that enhances the street appeal of any home. 

Color Adaptability

Plaster can be painted to any shade, allowing homeowners to match their exterior to their personal style or neighborhood aesthetic.

Weatherproofing: Protection Against the Elements  

New Zealand’s climate can be unpredictable, with heavy rains, strong winds, and intense sunlight. Exterior plastering acts as a weather-resistant barrier, safeguarding homes from these conditions, particularly in coastal regions subject to sea spray. 

Moisture Resistance

Properly and professionally applied plaster prevents water ingress, which means the the risk of mould and structural damage is significantly reduced.  

Wind Protection

A solid plastered surface minimises wear and tear caused by strong winds, ensuring longevity over time.  Especially in those vast open spaces subject to high winds, particularly by the sea. 

UV Resistance

High-quality plaster coatings protect against sun exposure, preventing fading and deterioration over time.  

Insulation and Energy Efficiency

Beyond aesthetics and durability, exterior plastering plays a crucial role in temperature regulation. This ensures your power bills are kept to a minimum. Plaster helps maintain indoor temperatures, keeping homes warm in winter and cooler in summer.  By reducing heat loss, plastered exteriors contribute to lower energy bills.  

Noise Reduction

Plastering adds an extra layer of soundproofing, making homes quieter and more comfortable.  

Fire Resistance: Enhancing Safety

Safety is a top priority in construction, and exterior plastering offers fire-resistant properties that add an extra layer of protection.  Plaster does not catch fire easily, reducing the risk of fire spread. In the event of a fire, plastered walls can slow down flames, providing more time for evacuation.  

Low Maintenance and Longevity

Unlike other exterior finishes that require frequent upkeep, plastered surfaces are low-maintenance and built to last for generations.

Properly and professionally applied plaster remains intact for years, reducing the need for costly repairs. It is also easier to clean than a lot of other building materials. A simple wash or repainting refreshes the look without majorly extensive work.  Plaster is exceptionally durable and withstands harsh weather conditions, ensuring a long lifespan.  

Exterior plastering is more than just a finishing touch on your walls. It’s a sound investment in your home’s durability, efficiency, and visual appeal. Whether you’re building a new home or renovating an existing one, plastering offers long-term benefits that enhance both protection and aesthetics.
