Render is a protective layer applied to outer walls to improve weatherproofing and prevent corrosion, staining, and deterioration caused by external factors like rain, wind, and algae. It also adds an attractive finish, likely to increase a property’s value.

At APT, our aim is to extend building lifespans through aftercare maintenance solutions. Trust us to provide excellent results when cleaning rendered walls and surfaces. Our unique soft wash render cleaning approach has been tried and tested to deliver excellent results every time, no matter how challenging and on different types of render. 

Here’s how we helped Torfaen Borough Council with removing green and red stains (organic growth) from their k render

“Another excellent job done by APT-ICC, carried out under very difficult, restrictive conditions. Instead of renewing the K Render at a cost of over £40,000, APT have restored it to almost new, a huge saving for a Borough Council. I would highly recommended APT for their expertise and forward-thinking approach.”

Our Render Cleaning Process

Mould, moss, and algae can cause unsightly stains on buildings, but our render cleaning process can effectively remove them using eco-friendly and safe cleaning products that don’t damage the surface. We don’t use bleach, which only delivers short-term results and harms the substrate material. 

Our soft washing and pressure washing cleaning methods ensure that our cleaning products are applied gently and without disrupting the substrate material and damage the render.

Our products quickly eliminate growth spores of algae, mould, moss, and fungi and provide long-term protection against regrowth. Render cleaner allows for the removal of unwanted surface staining.

After we’ve cleaned your rendered surface, we can also provide long-term protection to keep it looking clean and fresh. If you want to apply paint to your render, we recommend waiting until it has completely dried post-cleaning, and we can help with this process as well. Check out our Commercial Painting service for more information.

Why APT for Render Cleaning Services?

For over 30 years, APT has provided effective render cleaning solutions to residential and commercial clients across the UK. We begin each project with a comprehensive site-survey and detailed quotation, allowing us to recommend the most efficient and non-abrasive cleaning method for removing dirt, grime, algae and other contaminants from your rendered surface.

Our approach is sympathetic to the render and k render to prevent any damage. While some may assume that full re-painting is necessary to remove staining and discolouration, this is often an unnecessary and costly solution. 

Our cleaning process can effectively remove red stains, green algae, and restore the original colour of your render. In the past, high pressure cleaning was the only option available, but this aggressive method can cause damage and actually blast render off the wall. 

We use a more gentle approach to ensure long-lasting results without causing harm. Contact us today – sales@apt-icc.co.uk

When it comes to cleaning algae from render, we recommend using a professional render cleaning organisation to ensure the job is done properly. Cleaning render requires specific cleaning methods and render cleaning equipment to deliver outstanding results, fit to specification. We use APT’s Algae Free which is known UK wide as one of the best algae removers, this professional, concentrated algae cleaner kills spores on contact. Safe to use on a wide variety of surfaces, this is a 100% biodegradable, phosphate free, environmentally friendly formula. This is the best detergent for cleaning brick and all other external masonry surfaces.

Harsh environmental impact and contaminant build up, often in short periods of time can leave rendered properties looking dirty and worn, negatively impacting the appearance of the building overall. Cleaning render requires specific cleaning methods and render cleaning equipment to deliver outstanding results, fit to specification. Over the years, we have developed the best way to clean rendered walls (and other areas), bringing your rendered and k rendered properties back to life. Above we mention the most effective cleaning chemicals that we use to clean render on a regular basis – Algae Free & Exterior Building Render Cleaner.
To put it simply, k render is not self-cleaning. K render is one of the surfaces that is at the forefront of receiving harsh environmental impact and contaminant build up, often in short periods of time. This can leave rendered properties looking dirty and worn. This subsequently leaves a very negative impression of the building overall. When it comes to cleaning render, specific render cleaning methods are required, along with render cleaning equipment to deliver outstanding results. Our render cleaning method has been tried and tested and now trusted throughout the UK by the organisations we work with. Get in touch today to find out about our K render cleaning methods.

Rendered walls and surfaces are often attacked by environmental factors and wear and tear. Although durable and long-lasting, render can often become discoloured and stained. Some of the main causes of render discolouration are:

  • Organic matter
  • Algae
  • Lichens
  • Fungi
  • Cyanobacteria
  • Graffiti
  • Water Damage
  • Environmental Pollution
  • Weathering

High pressure jetting is not recommended as a method for render cleaning. Jet washing can easily damage the surface of the render and leave unsightly stains and leave stripes on the surface. Using soft washing and the most suitable, eco-friendly cleaning products will ensure that surfaces remain undamaged, whilst removing unsightly stains. 

We highly recommend against using bleach to clean your rendered surfaces. Using products with high levels of available chlorine from strong dilutions of sodium hypochlorite may harm some renders – and often cause serious damage to surrounding rubber and metal fittings around windows and doors. Bleaches and toxic products can present extremely dangerous long-term health hazards for the operator, customers and the environment. 

It is possible to purchase render cleaning chemicals from various shops, but it is important to note that these chemicals can be hazardous and dangerous to use without proper training and experience. It is recommended to use a professional render cleaning chemical to clean your property, as using biocides or bleach incorrectly can result in damage or harm.

For better cleaning results, using a suitable detergent or render cleaning chemical can effectively remove algae growth and improve the appearance of the render. In cases of minor algae growth, a light brush and rinse with detergent can remove the staining.

If left untreated, algae, mould and fungi growth on render can cause discoloration and damage to the surface. Typically, the side of the property that faces the most wind and rain will be worst affected. Neglecting to address this can result in moss and lichens growing, which can break down the render and cause cracks to widen. In extreme cases, this may require the building to be pre-rendered. To prevent buildups, it is recommended to apply a biocide annually.

Although patching up a rendered wall may be necessary in certain situations, such as when a window is being blocked up or there is damage to a wall, the finished result may not look aesthetically pleasing. This is because it is difficult to achieve a seamless match even when using the same batch of render. In most cases, it is recommended to re-render the entire wall to achieve an even finish. However, re-rendering can be a costly and time-consuming process. This is where a professional render cleaning organisation can help. By regularly cleaning and maintaining your rendered walls, you can extend the lifespan of your render and avoid the need for costly repairs or re-rendering. Our professional k rend cleaner, Bio Clean acts as a water repellant for your rendered surfaces.
