Does Your Project Require Rendering & Insulation?

What Is K Render?

What is K Render? You are probably not sure what is, which is why you’ve accessed this article.

What if we told you that it was a technology that did away with a lot of the mundane tasks which are otherwise associated with maintaining the look and feel of your home for the next thirty years?

In addition to making your home stand out, there are several other reasons why K rendering has become one of the most popular choices for homeowners in the UK.

This article dives what K render is, how it works and why you should consider investing in it.

What is K Rendering?

K rendering or K-rend is a brand name owned by the Kilwaughter corporation. The term similar to Walkman is used as a general catch-all term when referring to renderings or even a traditional render. However, there are a couple of distinct advantages associated with K-rend.

K-rend is used to produce a rend using an oversized coat of mineral-based material, which is then treated with limestone.

The advantage here is that you have access to over 500 different colours and various texture combos when buying the product, which allows a great deal of creative freedom over the appearance of the end result. K-rend is available in the pre-bagged form, and the pattern can easily be applied using a special machine or by hand.

K-rend also manufactures a product called “bucket mix”, which is mainly special organic resin renders that are also low maintenance. The renders don’t have any cement and are available in a ready-to-mix type paste. The mix is also referred to as simply “bucket mix.”  

The mixture contains silicone, making the final product breathable, water-proof, and for the most part, maintenance-free.

In addition, if you are rendering anything other than bare brickwork, you may also want to apply a base coat before using K-rend. This is especially the case if the surface being rendered is concrete.

If you need to prevent paint from peeling off, or if the home needs a better seal after it is rendered, the existing paint will need to be removed.

Keep in mind that K-rend may not be able to fulfil the requirements needed for exterior wall insulation. Still, this insulation can be added to lower your carbon footprint and lower your energy bills.

Why Consider K Rendering For External Walls?

There are a few reasons why you should consider K renders. Here are the benefits of using K renders:

  • Easy to clean
  • Durability despite harsh weather conditions
  • It is mainly algae resistant
  • Weatherproof

Easy to Clean Water Repellent Surface

Cleaning K-rend is easy and mainly takes a few seconds. However, it requires being treated with algaecide annually and washed with water using a garden hose. You don’t need a power washer to clean K-rend.


It is mainly designed to last for up to thirty years. This means that most people don’t have to worry about painting their homes every three to five years. After K-end has been applied to a home’s exterior, there is no additional decorating needed, mainly because you already have a wide variety of possibilities across various styles and colours.

It is Algae Resistant

K-rend was mainly developed to resist the growth of algae. Thus, if you reside in a rural or coastal region, choosing a finish that’s algae-resistant is essential. An algae-resistant or repelling finish reduces, if not eliminates, the likelihood of algae growth, especially in environments with cleaner air.


K-rend is, for the most part, impervious to most natural elements like rain, hail, extreme heat etc., mainly because it prevents water vapour from passing through. This means that excess moisture can pass through it, escaping from the home.

That’s why homes with K-render will not struggle with excessive condensation, which can make a home unpleasant leading to numerous health issues. If the resulting mould isn’t treated correctly, it can lead to various health issues; this k-rend saves homeowners lots of time and money in the long term.

K-rend is Perfect For The UK

The silicone used in K-rend makes it perfect for use in homes across the UK because it allows water vapour to move through it, thus decreasing the amount of moisture on its surface. The high quality extensive range of products available ensures that the property benefits from the max level of breathability while looking good in the process.

A water-repellent and durable weatherproof coating ensures that it will remain visually pleasant and last for decades. The finish will also feel drier, thus more resistant to mould and algae growth, making it easier to clean.

What is the Average Age of K-Render?

K-rend has an exceptionally long service life and can last up to 30 years if taken care of. You don’t have to repaint the home for the next 30 years. Thus the little extra it costs upfront saves you a bundle of money in the long term.

Final Word

We have seen K-rendering become extremely popular in recent years, and for a good reason. For starters, people love the finish on k-rendered homes and buildings, which offers a sleek and sophisticated look using the latest silicone technology. The dazzling colours and surface patterns can help your building or home stand out from the rest.

Plus, K rend can last for decades and all it needs is an annual fungicidal wash. That’s why K-render has become the material of choice for homeowners, especially those that want to use a technology that lasts for years, is easy to maintain, prevents health problems and adds to the value of their homes.
