Which Render Types Are Best For Your Climate?

Although there are different render types, not every render will suit every climate. For the best possible results and to get the most out of your money, you will need to understand the pros and cons of each render type and how it performs in different climate zones.

The last thing you want is to apply a render and have it become damaged because it does not withstand your local weather conditions.

So, which render types work best in which kind of climate?

Render and Climate

Renders provide an extra layer of insulation for a structure and offer weather- and water-resistant properties against UV rays, rain, and wind.

Cement Render

Cement render is a traditional render type made from cement, sand, water, and sometimes lime, which can be added to improve functionality. The ratio for the cement render mixture depends on the application (adding more sand will make it coarser, while less sand will result in a finer consistency).

What Climate is Best for Cement Render?

Cement render is best used in moderate and drier climates (but not too dry). A mild climate allows the cement render to cure and dry slowly and steadily, reducing the risk of cracking.

The ideal temperature to apply cement render is between 10℃ and 25℃, with low humidity.

Which Climate is NOT Best for Cement Render?

Cement render is not suitable for overly hot or cold climates, or for coastal areas with high moisture and salt content.

Avoid applying cement render at temperatures below 5°C or above 30℃.

Silicone Render

Silicone render is a modern render option that is usually available in a pre-mixed form and is made up of aggregates, silicone resins, cement, lime, water-repellent agents and colour pigments.

What Climate is Best for Silicone Render?

Silicone render offers the ultimate weather protection, making it ideal for wet climates and more extreme temperatures.

One of the most notable functions of silicone render is its water-repellent properties (hydrophobic), which prevent any moisture from being absorbed by the structure, lowering the risk of any structural damage. Its breathability also allows any moisture to escape, preventing mould growth.

Silicone render is also very durable, meaning it won’t fade easily, even after years of sun exposure, and it’s able to withstand extreme heat and humidity.

The ideal temperature for applying silicone render is between 5℃ and 35℃ with a humidity level below 85%.

Which Climate is NOT Best for Silicone Render?

Silicone render can withstand most climate conditions, including high temperatures and wetter conditions. However, it is not recommended to apply at temperatures below 5℃ or above 35℃.

Acrylic Render

Acrylic render is a modern, pre-mixed render that comprises acrylic polymers, cement, sand, colour pigments, water-repellent agents and reinforcing fibres.

What Climate is Best for Acrylic Render?

One of the most prominent properties of acrylic render is its high flexibility. This flexibility allows it to move along with a building’s natural movement due to temperature fluctuations, preventing any cracks from forming. Acrylic render is also more water-resistant and breathable than cement render, making it better able to withstand wetter conditions.

Its flexibility and water resistance make it well-suited to climates with high humidity or heavy rainfall, as well as coastal conditions.

The ideal temperature for applying acrylic render is between 5℃ and 30℃, and with a humidity level below 85%.

What Climate is NOT Best for Acrylic Render?

Acrylic render is not the best option for climates with extreme temperatures, high humidity or long periods of rainfall.

Lime Render

Lime render is a traditional render that has been around for centuries and is made from a simple mix of lime, sand and water. It is typically used on heritage-listed or historic buildings because they pose a lower risk of structural damage when lime render is applied.

What Climate is Best for Lime Render?

Lime render is both flexible and breathable, protecting it against moisture absorption, dampness, structural damage, and changes in weather conditions.

The best climate for lime render is one with high humidity and frequent temperature fluctuations. It is best applied in temperatures between 5℃ and 25℃.

What Climate is NOT Best for Lime Render?

Lime render is not suitable for use in cold climates with prolonged wet weather conditions.

Monocouche Render

Monocouche render is made from a mixture of white cement, sand, coloured pigments and additives, including either hydrated lime or silicone. It is usually mixed with water to form a paste and can be completed in a single layer/application process.

What Climate is Best for Monocouche Render?

Monocouche render is a breathable, strong and durable render that stands up to the elements quite well. It stands up best to moderate weather conditions (no wind or rain).

Monocauche render works best when it is applied in temperatures between 5℃ and 25℃.

What Climate is NOT Best for Monocouche Render?

Avoid applying monocouche render in extreme hot or cold temperatures, or in areas with heavy and persistent rainfall.

Climate Dos and Don’ts

Here are some essential tips to remember about rendering in different climates:

Do your research before selecting a render type, and make sure it suits your climate. Render can be expensive, and the last thing you want is to choose a render type that won’t hold up well in the environment you live in.

Avoid applying render at temperatures below 5℃ or above 25-35℃, depending on the type of render.

Avoid applying render during heavy rainfall or high winds. These wild weather conditions will disrupt the curing and drying process.

What Render Types Are Best for Sydney Homes?
