House rendering has become increasingly popular in recent years, with homeowners looking for ways to enhance the appearance and value of their properties. But what exactly is house rendering, and what are the different types available? In this comprehensive guide, we'll explore the ins and outs of house rendering, covering everything from the benefits it offers to the factors you should consider when choosing a rendering method for your home.
House rendering is the process of applying a protective and decorative coating to the external walls of a building. This coating can be made from various materials, each with its own benefits and drawbacks. Rendering serves several purposes, including improving the aesthetics of a property, providing additional insulation, and protecting the walls from weather damage.
There are several types of house rendering available, each with its own unique properties and advantages. Let's explore the most popular ones:
Cement rendering is a traditional method that uses a mix of sand, cement, and water to create a durable and robust finish. This type of rendering is known for its cost-effectiveness and versatility, as it can be applied to a wide range of surfaces.
Lime rendering is an eco-friendly option made from a mixture of lime, sand, and water. It's a breathable material, which means that it allows moisture to escape from the walls, preventing dampness and mould growth. Lime rendering is particularly well-suited to older properties, as it can help maintain the building's original character.
Acrylic rendering is a modern option that uses a mix of acrylic resins and other materials to create a flexible and durable finish. This type of rendering is known for its wide range of colours and textures, as well as its resistance to cracking and fading.
Silicone rendering is a high-quality, weather-resistant option that uses silicone-based materials to create a finish that repels water and dirt. This type of rendering is low-maintenance and long-lasting, making it an ideal choice for homeowners
Monocouche rendering is a single-layer, through-coloured rendering system made from a mix of cement, lime, and other additives. It's known for its quick application process and low maintenance requirements. Monocouche rendering is available in a variety of colours and finishes, making it an attractive choice for many homeowners.
House rendering offers several advantages, including:
When deciding on a rendering method for your home, there are several factors to consider:
The cost of rendering varies depending on the materials used and the complexity of the project. It's essential to set a budget before exploring your options and choose a rendering method that fits within your financial constraints.
Different rendering methods offer various finishes, textures, and colours. Consider the overall look you want to achieve for your property and choose a rendering method that matches your desired aesthetic.
The climate in your area plays a crucial role in determining the most suitable rendering method for your home. Some materials perform better in specific conditions, so it's essential to choose a rendering method that can withstand the local weather.
Different rendering materials require different levels of maintenance. For example, silicone rendering is low-maintenance and easy to clean, whereas cement rendering may need regular repainting to maintain its appearance. Consider the long-term maintenance requirements when selecting a rendering method.
The process of applying render to your home involves several steps:
Each rendering method has its own set of advantages and disadvantages. Here's a brief overview of the pros and cons of the most popular methods:
Regular maintenance is essential to keep your rendered home looking its best. Depending on the type of render you have chosen, maintenance tasks may include:
While some homeowners may be confident in tackling smaller rendering projects themselves, it's generally advisable to hire a professional for larger or more complex jobs. Professional renderers have the expertise and equipment needed to ensure the render is applied correctly and will stand the test of time.
The cost of house rendering can vary widely depending on the type of render used, the size of your property, and the complexity of the project. As a rough guide, you can expect to pay between £40 and £60 per square metre for traditional cement or lime rendering, with more modern options like acrylic and silicone rendering costing between £60 and £80 per square metre.
Before rendering work can begin, it's essential to prepare your home. This may involve:
Although rendering can provide numerous benefits for your home, it's not without its potential issues. Common problems include:
Cracking or flaking render: This can be caused by poor application, movement in the structure, or the use of an unsuitable rendering material. Repairing cracks and flaking render may require the removal and replacement of the affected area.
Dampness and mould growth: If the render is not breathable or has been applied incorrectly, it can trap moisture within the walls, leading to dampness and mould growth. Addressing this issue may require the removal of the render and the application of a more suitable material.
Rendering can improve your home's energy efficiency by providing an additional layer of insulation. This helps to reduce heat loss through the walls and can lead to lower energy bills. For even greater energy efficiency, consider incorporating external wall insulation (EWI) with your rendering project.
Ensuring your home is adequately insulated is crucial for maintaining a comfortable indoor temperature and reducing energy consumption. Rendering alone may not provide sufficient insulation, so it's essential to consider additional measures such as cavity wall insulation, loft insulation, or EWI.
House rendering can transform the appearance of your property while offering protection and increased energy efficiency. By considering factors like budget, aesthetics, weather conditions, and maintenance requirements, you can choose the most suitable rendering method for your home. Always consult with a professional renderer to ensure the best results and a long-lasting finish.
The lifespan of house rendering varies depending on the type of render used and the quality of the application. Generally, you can expect cement rendering to last around 20-30 years, while acrylic and silicone rendering can last up to 40 years or more with proper maintenance.
While some DIY enthusiasts may be able to tackle small rendering projects, it's generally recommended to hire a professional for larger or more complex jobs to ensure the best results.
The time it takes to render a house depends on the size of the property and the type of render used. Typically, a professional renderer can complete a standard three-bedroom house in 1-2 weeks.
Breathable rendering materials like lime can help prevent damp by allowing moisture to escape from the walls. However, it's essential to address any underlying damp issues before applying render to ensure the problem doesn't worsen.
In most cases, you won't need planning permission to render your house, as it is considered a form of 'permitted development.' However, if your property is listed or located in a conservation area, you may need to seek permission before undertaking any rendering work. It's always best to check with your local planning authority before starting any project.
