According to an article from TheGreenAge, developing the quality of your exterior walls is not only a good way to increase the value of your property but it is also a great approach in protecting your home from harmful damages and deterioration. Although there are other ways to perform this task, external rendering is one of the best and cheapest ways to accomplish it, explains First Renderers Ltd., experienced renderers in London.

In line with this, people that have rendered their walls or are planning to render their walls are asking whether or not it can be left unpainted. The reason behind this inquiry is that some people want to save money while others are already satisfied with the appearance of their unpainted rendered walls.

To be honest, the answer to this question really depends on the type of render that is used for your external walls. Some render types require you to paint over it to protect it from moisture while others are resistant to moisture and can be applied using a variety of colors to choose from.

To give you an idea of what we are talking about, here are some of the most common types of render that you can use for your home.

Common Types of Render

Lime Render

Based on Wikipedia, Lime render is commonly used on external walls that are made of bricks or stones. This type of render stops moisture from passing through your walls by absorbing it like a sponge and releases it to the air through evaporation when the rain stops.

Lime render is often left unpainted. However, you can alternatively apply limewash or use silicate paints that are breathable to paint over it.

Cement Render

Another type of render that is commonly used for walls is the cement render. This type of render is not suitable for use on older buildings because of its lack of flexibility which may cause cracking whenever your property is subjected to movements.

Cement renders are typically harder, stronger, and cheaper than lime render. However, this type of render is not waterproof and needs to be painted for added protection against moisture.

Acrylic Render

Before we continue on to the next type of render, it is important to know that the different render types can be classified as either thick coat type or thin coat type. The two types of render that we have described above (Lime and Cement) are classified as thick coat type simply because these type of renders needs to be applied thickly on your external walls.

Now, the next type of render is the acrylic render. This type of render is classified as a thin coat render because it is thinly applied over a special basecoat on your walls.

Acrylic Renders are typically the most affordable type of thin coat renders. It is impact resistant and super strong. Furthermore, this type of render is available in a variety of vibrant colors to choose from, making it unnecessary to be painted.

Monocouche Render

According to the online dictionary Linguee, “monocouche” is a French word for monolayer or one layer. Monocouche render is a thin coat type of render that is known for its flexibility, weather resistance, and low maintenance.

Although it is superior to other types of render and it can be applied easily on your external walls, its material cost is much more expensive than those render types that we have already discussed above.

The Monocouche Render produces a gorgeous finish due to the variety of color pigmentation available that is already pre-mixed with the render mixture. This means that additional painting over the rendered walls is not required.

Silicon Render

The last but definitely not the least type of render that we are going to discuss in this article is the Silicon Render. This type of render is classified as thin coat render and is probably one of the best types of render that is available in the market today.

The Silicon render has all the positive features and functionality of acrylic render with added unsurpassed breathability factor and amazing moisture permeability. This type of render amazingly repels moisture, allowing the rainwater to slide from its surface and clean the dirt and other debris that sticks on your walls.

Silicon renders are self-colored meaning it doesn’t need to be painted.

Final Words

Now that we discussed the different types of render types that are available for you to use to protect your walls from harmful damages and deterioration, we can now answer the question that asks whether or not rendered walls can be left unpainted.

Based on the facts that we have acquired from the different types of render that are available for you to use for your property, rendered walls can be left unpainted with the exception of the ones that use cement render which requires you to paint over it to protect it from moisture.
