What is Silicone Render?

Silicone render is a thin coat of cement that can be applied to the external walls of a property. This type of rendering mixes silicone and resin, a combination that offers greater flexibility than traditional types such as acrylic render.

Traditional renders are made from materials such as sand, cement, and lime, which can take weeks to dry before being painted to achieve your desired finish. However, what’s great about silicone render is that it requires just a few hours of drying time. We also enjoy using coloured render at Advanced Damp to offer you a quicker and more affordable job.

Silicone render is ideal for homes in damp climates that are susceptible to wet rot, because it acts as a barrier against moisture. This prevents the walls from becoming cracked, while giving your home that polished look you’ve been aiming for.

Rendering also acts as a form of wall insulation, which makes your home more energy efficient and therefore reduces heating bills too.

Types of Silicone Render

We use several formulations and types of render here at Advanced Damp, allowing us to achieve a durable finish with every property that we work on.

Below, we’ll examine the silicone render systems that are most popular with our customers, to help you make the right choice for your home:

  • Through coloured render – Using coloured render means that there’s no need to apply a separate splash of paint once the base coat is dry. This allows us to get the job done more quickly, at a much more affordable price!
  • Mineral silicone render – Try this type of quick-drying cement render if you’re aiming for a more natural look to suit your property. Its blend of minerals provides a textured finish ideal for quaint cottages and rural abodes, along with rustic-looking homes.
  • Acrylic render – Acrylic render contains a type of plastic called resin, which offers excellent stain and water resistance. Silicone render systems using acrylic are also highly crack-resistant and leave a smooth finish on your walls.

Pros of Choosing Silicone Render

Not yet convinced that silicone renders offer the right type of protection for the walls of your home? Here are three key reasons why this thin coat render is a superior choice when it comes to properties based in the wet UK climate:

Offers Great Water Resistance

Silicone render is one of the most popular choices for property owners, compared to other rendering types, mainly because of its water-repellent properties.

Older rendering made from sand or cement will absorb some moisture when regularly exposed to rain, making it susceptible to cracking or fading. Using a unique silicone resin binder instead builds a strong waterproof barrier to prevent this absorption and protect the walls of your home from any moisture damage.

We can also apply either an acrylic or silicone top coat to mineral and acrylic render systems, which further protects them from poor weather conditions.

Long Lasting

Silicone resin is the final layer applied during the installation of an insulation system, meaning that some vital preparations must be made to create a professional finish.

Our expert house rendering team will therefore ensure that your walls are clean and damage-free before jumping straight into the silicone render application. This can take a few days to complete, but the process ensures that your home is protected for 25 to 30 years, come rain or shine!

Easy to Apply

At Advanced Damp, we can complete the silicone renders application process efficiently thanks to our thorough preparation process.

This involves removing dirt and fixing any damage that could prevent a smooth silicone render. We’ll then use repair mortar to fill in any holes and finish with a base coat, leaving a system with great flexibility that is unlikely to crack in extreme weather conditions.

Cons of Silicone Render

All types of rendering have their drawbacks in terms of application and suitability that you should consider before making an informed choice.

Labour Intensive

As a family-run business, we understand the value of creating a safe and secure home for the future of you and your loved ones. We therefore take great pride in applying silicone renders to your home with minimal disruption and mess, ensuring a hassle-free experience that completely transforms your family home.

Our team will allow the silicone render to cure for around 2 to 7 days in the final application stage, depending on the humidity and temperature of the climate. While this gives it plenty of time to thoroughly dry, it can mean that the entire process takes a little longer to complete than other types of rendering.

Requires Warm Weather

Silicone render is ideal for UK climates because it can be even when it’s raining – we won’t let wet weather put us off!

Unfortunately, we will have to delay our start date if temperatures drop too low, as cold weather prevents the render from setting and increases the risk of cracks showing.

However, our expert team members will explain how you can protect the rendering from heavy rain or intense sunlight during the curing stage, before we apply the final silicone top coat.

Is Silicone Render Cost Effective?

Silicone render can be priced anywhere from £55 to £85 on average per square metre, which generally includes labour and materials. The cost varies depending on the type of rendering chosen, the base coat used, the size of your property’s exterior, and additional costs such as waste removal.

This price is approximately around twice that of a traditional cement mix, making silicone render systems a bigger financial investment than sand, cement, lime, or monocouche render.

However, one of the biggest benefits of installing this system is the savings you’ll make when it comes to energy bills.

For instance, by acting as a form of thermal insulation, you’ll find it easier to stop heat from escaping and maintain a constant temperature, therefore making your home more energy efficient. Not to mention you’ll be saving the planet too!

At Advanced Damp, our focus is on cost-effective weather and damp proofing options. All of our Trustmark-endorsed services, including silicone render, are competitively priced and come with a 20-year guarantee.

Frequently asked questions

Check out our list of frequently asked questions below to find out more about using silicone render, including how it can improve both the aesthetics and efficiency of your home.

Silicone render is an excellent choice if you're looking for durable, long-lasting protection for the external walls of your home. Thin coat render is ideal for preventing damage caused by extreme weather conditions, such as heavy rain or intense sunlight, and can prevent walls from cracking or fading.


Thin coat renders tend to last anywhere between 25 to 30 years on average, making them a highly durable form of wall protection. However, many factors could shorten or lengthen this time frame, including the climate, your location, the size and type of property, and the quality of application.

At just 6 to 10 mm, the total build-up of silicone render is a lot thinner than traditional cement render, which is typically around 25 mm. This thin coat makes silicone render an ideal choice for maximising your internal space. However, the exact thickness will depend on how straight and plumb your property's walls are.

Silicone render can be applied over good-quality existing render systems that have been properly prepared, such as those made from cement, lime, or acrylic materials. However, painted render should be removed first, because the paint's texture may prevent the new coat from properly adhering to the walls of your property.

Silicone render is unlikely to crack because it is highly durable. When applied in thin layers, working from the bottom up with a steel trowel sponge float, it can last for up to 30 years. Applying a base coat beforehand will also prevent any cracks from forming due to movement.
