House Exterior Finishes: Advantages, Disadvantages, and Types of Renders Examined
House rendering, a type of cladding for the exterior of a house, is a popular choice for homeowners seeking to improve the aesthetic value and durability of their homes. This article will delve into the various types of house render available, their benefits, and potential drawbacks.
Firstly, let's discuss traditional cement render. While it is a common choice, cement render is prone to cracking over time and requires regular repainting. However, lime render, a more flexible alternative, is a suitable option for old houses, providing a breathable finish essential for maintaining the original functionality of the house.
For those concerned about moisture problems in old walls, lime render is a recommended choice. It offers a flexible solution that prevents such issues. On the other hand, acrylic renders, applied as a thin finish coat to seal and enhance the appearance of the underlying coat, are also an option. Fibers are added to prevent cracking, making acrylic renders a durable choice.
Monocouche render, a newer type of house render, originating in Europe, offers a flexible and hard-wearing, low-maintenance finish that's weather resistant and visually appealing. Monocouche render uses white cement and is pre-coloured (in any colour you want), and can be applied in one coat, making it quicker and less labor-intensive than traditional house rendering products.
Silicone render, another option, is self-cleaning and promises a longer life. Some claim it allows rainwater to wash away dirt, making it a low-maintenance choice. Coloured render can be either painted or through-coloured, with the latter being lower maintenance and requiring no subsequent repainting.
Polymer render, pre-mixed in bags and less prone to cracking, is often available in a variety of colours and through-coloured options. Self-cleaning renders, such as PermaRock's Nano-Quartz technology renders, have a surface designed to prevent dirt from sticking.
External wall insulation systems, made up of insulation layers, meshes, and top coat renders, promise a modern, clean-looking finish and are ideal for those worried about adding insulation internally to solid walls. These systems can often be applied in one coat, reducing labor costs.
It's essential to note that house rendering is not a cheap option, especially for large properties. Proper weather protection is necessary to ensure its longevity. Companies that manufacture monocouche render mixes include Knauf, Baumit, Sto, Weber (Saint-Gobain), and Sika.
Lastly, planning permission is usually not required for rendering a house in a terraced or semi-detached house, but it's always best to check with the local planning department before starting work.
In conclusion, house rendering offers a range of options for homeowners seeking to improve the appearance, durability, and energy efficiency of their homes. Whether you opt for traditional cement render, lime render, acrylic render, silicone render, monocouche render, or polymer render, each choice comes with its unique benefits and potential drawbacks. Always consider the specific needs of your property and budget before making a decision.
