Types Of Render

There are various types of render available for homeowners, including cement render, lime render, silicone render, monocouche (through-coloured) render, acrylic render, and cork-based render.

Cement Render

Cement render is a popular and cost-effective option for homeowners looking to enhance their home’s exterior while providing added protection against the elements.

It consists of a mixture of cement, sand, lime, and water that forms a durable coating when applied to the external walls of a house.

However, there are some considerations before opting for cement render as your choice. While it is known for its durability and longevity – often lasting up to 30 years – it’s essential to maintain proper sealing as lack of regular maintenance can make it susceptible to moisture infiltration, leading to cracks or damp issues over time.

Lime Render

Lime render is a traditional and eco-friendly option for homeowners seeking to enhance the appearance and protect the exterior of their homes. Made from a mixture of sand, water, and lime – specifically hydraulic or hydrated lime – this type of render is well-suited for older buildings with solid walls or those made from materials such as stone or cob.

One notable characteristic that sets lime render apart from other types is its flexibility. Unlike cement renders, which can be prone to cracking due to weather conditions or building movement, lime-based materials are known for their ability to adapt without compromising structural integrity.

This makes it an ideal choice for period properties that require added protection while preserving their historic charm. Additionally, these renders come in a wide range of colors and finishes so you can customize your home’s appearance according to your preferences.

Silicone Render

Silicone render has quickly become a popular choice among home owners due to its many advantages. As a modern, high-performing rendering option, it offers excellent benefits like water resistance and breathability.

One major advantage of silicone render is its extensive range of colors that can be incorporated into the mix without the need for painting over it later on.

Apart from providing a visually appealing finish, it also boasts impressive durability and low maintenance requirements as it’s less prone to cracking and algae growth compared to traditional cement renders.

For example, if you live in an area with frequent rainfall or high humidity levels, opting for silicone render can save you both time and money on external wall upkeep in the long run.

Monocouche (Through-Coloured) Render

Rendering a HouseMonocouche render is a popular rendering option for homeowners. It is a pre-mixed, one-coat rendering that is applied in a single layer to the exterior of your house.

Unlike other types of renders, this type comes in a range of colors and finishes, which means that it does not require painting or decorating after application.

This can save you time and money on maintenance costs in the long run.

One thing to consider before choosing monocouche render is that it can be more expensive than other types of renders due to its color options and durability. However, with proper maintenance, this type of rendering can last over 20 years without needing any repainting or touch-ups.

Acrylic Render

Acrylic render is a popular choice among homeowners due to its versatility and flexibility. It is commonly used in modern homes as it can be tinted with a range of colors, giving the property a contemporary look.

Acrylic render has an excellent texture that can easily cover different surfaces, including brickwork and concrete.

One significant advantage of acrylic render is that it’s water-resistant and durable. This type of rendering material works well in areas prone to dampness, ensuring that moisture doesn’t penetrate through the walls into your home’s interior space.

Additionally, acrylic render requires very little maintenance as its color does not fade easily compared to other types of renders like traditional lime or cement-based render.

Cork-Based Render

Cork-based render is an eco-friendly option for homeowners who want to go green. It is made from natural cork mixed with a polymer binder, creating a breathable and waterproof surface that provides excellent insulation.

This type of render has become increasingly popular in recent years due to its insulating properties, low maintenance requirements, and durability. The texture of cork-based render gives it a unique look, which can add character to any home.

One important thing to note about cork-based render is that it requires a professional tradesperson who knows how to apply this type of finish correctly. You’ll also need planning permission before applying cork-based rendering if you live in a terraced or semi-detached house since neighboring houses may be affected by the work being done on your property.

Factors To Consider When Rendering A House

When considering rendering your home, there are several factors to keep in mind, such as the materials used, the type of house you have, and whether you want to go the DIY route or hire a professional.


Proper selection of materials is crucial when rendering your house. Here are the factors you should keep in mind:

  • Type of Render: There are various types of render, such as cement render, lime render, silicone render, monocouche (through-coloured) render, acrylic render, and cork-based render. Each type has its unique properties and advantages.
  • Insulation: Some renders come with insulation properties that provide thermal benefits to your home.
  • Breathability: It is essential to choose breathable renders that prevent dampness and allow moisture to escape.
  • Colour Range:Consider choosing a colour range that complements the surroundings and enhances your house’s appeal.
  • Durability: Opt for durable renders resistant to cracking, peeling, or fading.

Type Of House

Different types of houses require different approaches to rendering. Here are some factors to consider when choosing the right render type for your house:

  • Brick Houses: Brick houses tend to benefit from a lime render that is more breathable and flexible, allowing moisture to escape and possibly helping reduce dampness.
  • Timber-Framed Houses: Timber-framed houses typically require a render system that is flexible enough to endure any movement in the building’s structure. A silicone or acrylic render might be suitable.
  • Terraced Houses: Terraced homes might benefit from a textured finish such as monocouche (through-coloured) render. They can also benefit from a waterproofing agent incorporated into the mix.
  • Pebble Dash Houses: Pebble dash houses usually have thick layers of mortar covered with pea-sized stones or gravel, making it hard for traditional renders like lime to adhere. Acrylic or silicone renders suit this type of house better.
  • Period PropertiesTraditional cement-based renders can harm historic buildings by trapping in moisture, potentially leading to structural damage. Lime renders breathe more efficiently and are therefore generally recommended.

Remember that the type of house you’re rendering should factor into your decision-making process.


Rendering HouseRendering a house can be costly, and homeowners need to consider the potential expenses before embarking on this project. Factors such as the size of the property, type of material used for renderinglabor costs and any additional work needed to prepare surfaces all add up.

However, while it may seem like an expensive undertaking initially, there are significant long-term benefits to rendering your home. By adding an extra layer of insulation to your house’s exterior walls, you’ll save money on energy bills in the long run.

Homeowners should carefully weigh their options based on individual needs and budget constraints when considering house rendering.

Added Value

By rendering your house, you can add significant value to your property. A well-executed rendering job drastically improves the curb appeal of a home and adds an extra layer of insulation that makes it more energy-efficient.

In fact, according to research by the Royal Institution of Chartered Surveyors (RICS), external wall insulation can increase the value of a home by up to 14 percent.

If you’re considering selling in the future, making this investment in your home could pay off greatly when it comes time to put it on the market. Plus, added insulation means lower heating bills and better soundproofing from outside noise, two factors that many potential buyers will appreciate.

DIY Vs. Professional Rendering

When deciding whether to render your house by yourself or hire a professional, there are several factors to consider. The table below compares the two options, helping you to make an informed decision.

DIY Rendering Professional Rendering
Cost-effective, as you save on labor costs. More expensive due to labor costs, but can save time and effort.
Requires learning and mastering the techniques yourself, which can be time-consuming. Professionals have the experience and expertise to provide a high-quality finish.
Potential for mistakes and low-quality finish, especially for first-timers. Better guarantee of a smooth and uniform surface, improving the appearance of the exterior of your house (Fact 8).
Less assurance that the surface is properly prepared for rendering, potentially leading to issues like cracking, mold, algae, and flaking paint (Fact 4). Professionals ensure proper surface preparation, including cleaning, repairing, and priming, which is crucial for a successful rendering project (Fact 10).
May not be aware of local planning permission requirements, potentially leading to legal issues. Experienced professionals are knowledgeable about planning permission and can guide you through the process.
Requires investment in tools and materials, which may not be used again. Professional renderers already have the necessary tools and can source materials at a better rate, saving you money in the long run.

In conclusion, DIY rendering can be a cost-effective option for homeowners with the time and patience to learn the process. However, hiring a professional renderer ensures a higher quality finish, proper surface preparation, and adherence to planning permission requirements. The choice ultimately depends on your individual needs and circumstances.

Planning Permission

Before rendering your house, it’s important to check if you need planning permission. Generally, if the exterior of your home is going to look significantly different from the neighboring houses, or if you are adding insulation that changes the appearance of the building, then planning permission may be required.

In some cases, however, planning permission might not be necessary. For example, if you’re using a similar finish and color as what was already on the house or just repairing existing render without changing its type or color.
