Technology improvements in External Rendering

Rendering is a process of applying a premix of cement, sand and other substances used in the construction industry including coloring agents and silicone to bricks, stones or other materials. Rendering can be for internal use or for external use.External Rendering refers to rendering that is done on the external walls of houses, office buildings or any other constructed or built-up place.

Rendering can be considered as a necessity as well as a luxury. It is considered as a necessity because it is absolutely essential to render the external walls of a house after construction to make them safe and secure and to protect them from moisture or Limebloom. When Silicone water repellents are added to the Render it makes them resistant to water and rather repel water. In this way the Render prevents the growth of algae on the external walls of a house. For some, Internal Rendering is a luxury because it is used for decorative purposes only and does not otherwise add any strength to the walls or the pillars and beams in a house.

External rendering is carried out by professionals who have significant years of experience and are well versed in the art and science of Rendering. These professionals are either workmen who work with a large service provider or are workmen cum owners of small outfits that carry out turnkey projects for homeowners as per their needs. In such assignments, the Render material is either purchased by the homeowners, or the workmen prefer to buy the Render material on their own and then bill it into their invoice to the homeowners. Either way, in both cases it is the quality and type of the Render material that makes the difference.

There are different types of Renders that are available in the market today – from the most basic ones to the most sophisticated ones. At the basic level, what one gets is the grey colored Render that is really a pre-mix of cement and sand. Beyond this are other types of Renders that use white Portland cement so it is possible to mix coloring agents in the Render and make it viable for use in the form of colour renders. In such cases homeowners get color swatches from Render suppliers and they can select a color based on their needs.

At the top end are Renders that are manufactured using Silicone technology. K- Rend is one such Render used in External Rendering that is made with Silicone technology. In this type of Render, Silicone water repellents are embedded in the Render which makes them repel water and gives a fresh look to the surface. Also with the help of the Silicone technology the Render makes it possible to have water vapor pass through it and this makes the substrate literally ‘breathe air’.

K-Rend are a Render that has been manufactured by the Kilwaughter Chemical Company and is available throughout the UK. What makes it unique is the fact that it is in high demand and comes with the prestigious quality certification Kitemark license to BS EN 998:2010.
