Choosing the right render

There are many factors to take into account when selecting a render. From the type of building to weather conditions, it is important that the the correct type of render is chosen. Between aesthetics and functionality, there is a vast range of different renders to choose from, so how do you go about selecting the correct render?

The material of the building that is to be rendered plays a large part in selecting the most appropriate type of render to use. Older buildings tend to be made from materials that have a lot of movement, so will need a flexible render which is able to move with the building. At the opposite end of the spectrum, newer buildings are constructed with stiffer materials so will need to be coated with a more rigid render. 

Renders both help improve the exterior appearance of a building and can help in both protecting against the elements (weatherproofing) and insulating the building itself

Types of render

Lime render tends to be more expensive than other types of render. Its flexibility makes it more suited to older buildings. One other thing that needs to be taken into account is that lime render should be maintained with frequent coatings of lime-wash.

Cement render is a more rigid render and is available in a variety of bold colours. Being relatively quick to apply and cure, cement-based renders are the go-to choice for most modern buildings.

Method of Application

There are several methods of applying render to a substrate, and their preparation is something that needs to be considered before making a choice. Renders can be applied via hand or spray gun. Hand-applied renders require more work in their application, whereas spray guns allow for a quick and easy method of applying render. 

One final point to consider is local planning regulations. Render can be a stark contrast against non-rendered, brick buildings which can sometimes be an issue with occupants of surrounding properties. There are however, various types of render and their application - such as brick render - which offer a subtler solution.
