Silicone Rendering

In the world of exterior rendering, you’ll find that silicone render constitutes a significant advancement in facade finishes. Offering a plethora of benefits ranging from durability to aesthetic versatility, this type of render stands out for its resilience against various weather conditions. Utilised correctly, silicone rendering can not only enhance the thermal performance of your property but also sustain its pristine appearance for longer periods compared to traditional rendering methods.

Understanding the application technique of silicone rendering is crucial for achieving the desired outcome. At Shape Up, we streamline the rendering process by breaking it into manageable stages. Our process ensures that every layer adheres to the substrate effectively, providing a solid foundation for the subsequent coats. Whether you are looking to protect and maintain an existing building or create a new and modern look, silicone rendering is an excellent choice.

Navigating through the options available for silicone rendering presents you with various textures and colours that can completely transform your property’s exterior. It’s essential to consider the local climate conditions and architectural style when selecting your finish, ensuring that the render choice not only provides protection but also complements the building’s design. The flexibility of silicone render coupled with the systematic Shape Up approach results in a harmonious blend of functionality and visual appeal that elevates your property’s facade.

Fundamentals of Silicone Rendering

Silicone rendering serves as both a robust and decorative external wall coating, offering an impressive longevity and ability to withstand harsh weather. This method not only enhances your building’s aesthetics but also acts as a shield against moisture, contamination, and temperature fluctuations.

Silicone Rendering Materials

  1. Silicone Resin: The key ingredient that provides flexibility and resistance to environmental influences.
  2. Mineral Aggregate: Adds structure and body to the render, enabling it to bond effectively to the wall surface.
  3. Colour Pigments: Available in various hues, allowing you to match or enhance your building’s facade as you see fit.
  4. Reinforcement Fibres: Sometimes incorporated to strengthen the final coat and minimise the risk of cracking.

It’s vital to select the right silicone render mix, ensuring it includes the appropriate colour pigments and that the mineral aggregate is of the correct granularity for the desired texture. This is where Shape Up makes the difference, providing the highest-quality silicone render for your home.

Silicone Rendering & External Wall Insulation

Silicone rendering offers several benefits:

  • Breathability: Unlike some other render types, silicone allows walls to transpire, reducing the likelihood of water damage.
  • Colour: Silicone renders are pre-coloured, which eliminates the need for separate painting and increases durability, as the colour persists throughout the material.
  • Application: The thin coat render is efficiently applied in a single layer by a skilled professional.

External wall insulation involves the addition of an insulative layer to the outside of a property, which is then covered with a protective render. Here, the objectives extend beyond just aesthetics:

  • Insulation: EWI significantly improves thermal performance, keeping your home warmer in the winter and cooler in the summer.
  • Energy Efficiency: By enhancing insulation, EWI can reduce heating bills, making it a cost-effective long-term investment.
  • Property Value: It could potentially increase the value of your property due to improved energy efficiency and updated exterior aesthetics.

The Benefits of Silicone Rendering

Silicone rendering offers you distinctive advantages for your property’s exterior by coupling protective qualities with aesthetic flexibility. Harness these benefits to enhance durability and present an appealing exterior facade.

Durability and Weather Resistance

Your building gains exceptional resilience against harsh weather conditions with silicone rendering. Its noteworthy characteristics include:

  • Resistance to cracking: The rendering’s flexible nature adapts to temperature changes, reducing the likelihood of cracks.
  • Colour stability: Expect minimal fading or discolouration, retaining the visual appeal for prolonged periods.


Critical to maintaining your property’s structural integrity, silicone rendering’s breathability allows moisture to evaporate from the walls. This essential feature:

  • Prevents moisture build-up: Protects against damp and mould formation.
  • Enhances internal air quality: Improves your living conditions by allowing the building to ‘breathe’.

Easy to Clean & Maintain

Keeping your property pristine is less labour-intensive due to the low maintenance requirements of silicone rendering. Quick and efficient maintenance is facilitated by:

  • Stain resistance: A simple wash with water or mild detergent suffices to remove unwanted marks.
  • Ease of cleaning: The non-porous surface prevents dirt embedding, making upkeep a breeze.

Applying Silicone Rendering

When you opt for silicone rendering, you’re selecting a wall finish that is not only aesthetically versatile but also robust against various weather conditions. The silicone-based formulation provides a breathable yet water-resistant barrier for the exterior of your building, ensuring longevity and ease of maintenance.

Preparation Process

Before the silicone render is applied, it’s crucial that the surface is ready to ensure optimal adhesion and finish. At Shape Up, we follow these steps:

  1. Inspecting the surface: We ensure the area is free from any damage, and repair any cracks or uneven sections.
  2. Cleaning the surface: We remove all debris, dust, and dirt with a brush or pressure washer.
  3. Applying primer: Depending on the type of surface, a specific primer may be required for better adhesion.
  4. Masking off areas: We use tape to protect windows, doors, and other surfaces from unwanted application.

It’s important that the conditions are dry and mild, as extreme temperatures can negatively impact the application process.

Colour Choices

When selecting the right colour for your silicone rendering:

  • Consider the visual style you desire and how it harmonises with the surrounding environment.
  • Select from a wide variety of colours to match your personal taste or the building’s character.
  • Keep in mind that silicone render maintains its colour over time, and is resistant to fading in sunlight.

To visualise your options, refer to a colour chart which can assist in making an informed decision that suits your desired aesthetic.

Maintenance and Care

Proper maintenance ensures the longevity of your silicone render, maintaining its appearance and functionality over time.

Routine Cleaning

You should perform cleaning annually to preserve the facade. For routine cleaning:

  1. Use Soft Brushes: Gently brush off any loose dirt.
  2. Mild Detergent: Apply a solution of warm water and mild detergent.
  3. Rinse Thoroughly: Hose down with clean water to rinse off any residual soap. Avoid high-pressure washers as they can damage the render.

Damage Repair

Timely repair of any damage is crucial for maintaining the integrity of the render.

  • Cracks: Fill small cracks with silicone caulk matched to your render colour.
  • Discolouration: For localised stains, spot clean with a mild detergent.
  • For extensive damage, consult with our professional team.
