The Ultimate Render Cleaning Guide - What is Render Cleaning?

What is Render?


Render is commonly used across the world to provide the final external finish for commercial and domestic properties. Modern render is specially formulated to help protect buildings from the elements. A properly applied render will prevent water from entering a property. It will also help insulate the building in extreme hot or cold temperatures.


As well as being a practical finish, modern render is also very attractive. Render can be coloured using various pigments or given a patterned or textured finish using other specialist processes. As a result, it is a prevalent choice for all types of building projects.


Façades should undergo regular cleaning to extend the lifespan of render and keep properties looking their best. Cleaning render removes contaminants, staining and discolouration from the building's surface and restores the façade to its original aesthetic condition. Keep reading to find out more.


What is Render Cleaning?


Over time, render will begin to discolour. This discolouration happens from a range of factors, including algae growth, mould, leaking pipes and weathering. Render can also be stained by graffiti, paint and environmental pollution. Exterior render cleaning removes these contaminants from the surface of the render, returning the façade to its original colour and condition.


Render is often cleaned using a combination of specialist chemical solutions and steam cleaning. This staged process allows operatives to remove virtually all types of staining and discolouration from the surface of the render. Experienced operatives should only carry out the cleaning of render as incorrect chemicals and processes can permanently damage the render.


What can Render Cleaning be Used For?


Render cleaning is used to remove staining, discolouration and unwanted substances from the surface of render. Organic substances such as mould, algae and atmospheric pollutants (e.g. exhaust fumes) can build up on the rendered surface of the building. These contaminants often cause discolouration and staining, making the exterior façade of the building appear unsightly.


Cleaning render walls and other surfaces remove these organic substances and pollutants. This restores the render to its original aesthetic condition and gives the outside of the property a fresh, clean aesthetic. Render cleaning can also be used to remove graffiti from rendered walls thoroughly.


Cleaning the render on the external façade of a building can lead to a dramatic improvement in the property's overall look. As well as being aesthetically beneficial, render cleaning removes substances and contaminants that can cause potential harm to the render.



Why Use Spectrum for Render Cleaning?


Spectrum has extensive experience cleaning all types of traditional and modern render. Specialist knowledge is essential for render cleaning services as incorrect chemicals and processes can easily cause permanent damage to rendered surfaces.


All too often, amateur contractors use chemicals or systems unsuitable for K render cleaning and cleaning other types of modern render. The resulting damage is tough to put right. In many cases, the surface will need to be re-rendered to restore it to its former condition.


As we have specialist expertise in the area, our teams can select the correct chemicals and processes every time. As well as protecting the render from potential damage, this ensures a great result from every render clean we carry out.


We use steam instead of high-pressure jets to clean render. Our process will not crack or damage the surface of the render. Instead, the steam gently lifts contaminants and discolouration from the render to leave the surface, looking like new.


Another important reason to choose Spectrum is our expertise in access. Often, sections of render that need to be cleaned are located in high elevations. Areas of a façade can be difficult to reach. Our teams can use a combination of rope access and cherry pickers to reach all parts of a property efficiently.


Using rope access minimises the need for heavy machinery and scaffolding and saves our clients a considerable amount of money. On many projects, we can save our clients up to 70% in access costs alone. This is another compelling reason to choose Spectrum for your render cleaning project.


What is our P.A.S.T. Cleaning Process?


Our expertise and experience in render cleaning have led us to develop our unique equipment and processes. Our specially designed, patented tools, many of which are 3D printed by us, allow our operatives to reach even further. It gives them access to areas of buildings that would not be possible using other methods.


Our operatives often use this specialist equipment as part of our four-stage P.A.S.T cleaning process. This process combines specially selected chemical treatments with steam cleaning to thoroughly remove all traces of algae, mould, staining and pollution. The process can be used on all types of modern and traditional render.


The P.A.S.T process is so effective we can also use it to clean cladding and a range of other surfaces. This enables our teams to clean all types of façades and materials when they are on site. One of the significant benefits of the process is that it treats surfaces with biocide and cleaning solution. This kills organic compounds like algae and mould and helps to prevent their regrowth.


As well as being experts on modern render, we also host CPD webinars on cleaning the substrate. This allows us to share our experience with other professionals and promote the proper care and maintenance of modern render.
