Render is an essential part of modern building construction, and it’s used to protect exterior walls from harsh weather conditions. Whether constructing a new building or renovating an old one, render is often applied to give the building a fresh look. But many people ask one question: how long does render last? The durability of the render can vary depending on several factors, such as the type of render used, application method, climate conditions, and maintenance practices. This article will explore these factors in-depth and provide insights into how long your render can last.

Types of Render
When it comes to rendering, the type of render you choose can significantly impact how long it lasts. The three main types of render are cement, lime, and acrylic. Cement rendering is durable and long-lasting but can crack over time due to rigidity. On the other hand, lime rendering has a more flexible composition making it less prone to cracking and peeling, but it may require more frequent maintenance due to its porous nature.
Acrylic render is an increasingly popular choice for those seeking durability and low maintenance. It is resistant to fading, cracking, and weathering while providing insulation benefits. However, some argue that its synthetic composition leads to an unnatural appearance compared to traditional cement or lime renders.
Effects of Weather
Weather conditions have a significant impact on the lifespan of the render. Render is a sensitive material, making it susceptible to weather damage, such as cracking and fading. In addition, rainwater can penetrate through cracks in the render, causing dampness and mould growth, significantly reducing its lifespan.
In addition to rain, strong winds can also cause significant damage to render. High-speed winds carry debris that may hit the surface of the render and cause chips or cracks. Harsh weather conditions, such as extreme heat or cold temperatures, can also weaken the structure of the render leading to premature ageing.
Carrying out frequent inspections and maintenance checks is essential to protect your rendered walls from harsh weather conditions. Regular cleaning will help you identify any signs of damage early enough before they become severe. In addition, applying a water-resistant coating such as silicone-based paint will prevent water from seeping into your wall, keeping it dry and increasing its durability against harsh weather conditions.
Quality of Installation
The quality of installation plays a significant role in determining how long the render will last. A poorly installed render can deteriorate quickly, reducing the material’s lifespan. Therefore, it is essential to ensure that the surface receiving the render is prepared correctly before applying it to avoid any problems in the future.
Regular Maintenance
Regular maintenance is essential for the longevity of all building materials, including render. Render can last anywhere from 20 to 50 years depending on the type, quality and environmental factors such as weather. However, regular cleaning and upkeep will ensure its lifespan is maximized.
Lasting Expectations
When it comes to architectural renders, clients often ask how long this render will last. The truth is that the lifespan of a render depends on several factors, including the quality of materials used, the environment in which it is displayed and whether it is adequately maintained. With proper care, high-quality renders can last from 20 to 50 years.
Conclusion
The lifespan of the render depends on a variety of factors. One of the main factors is the quality of materials used during application. High-quality renders can last up to 20 years or more without showing any signs of wear and tear.
