Restoring Faded or Discoloured Render: Techniques for Renewed Brilliance

27th June 2023

If you have noticed your render starting to look dull or discoloured, don’t worry, there are solutions. In this blog post by Just Clean Property Care, we will explain the causes of discolouration and provide techniques for restoring your render’s brilliance. We’ll also offer tips for preventing future discolouration and how to choose professionals who can help with your render cleaning needs.

What causes render to become discoloured?

Discoloured render can be caused by a variety of factors such as biological growth like algae and mould, pollution, and even bird droppings. These elements attach themselves to the surface of the building material and over time, leave unsightly marks that lead to discolouration.

Cleaning is one effective solution for restoring discoloured render. Regular cleaning combined with specialized techniques help remove any build-up of dirt or grime on the surface without causing damage to the material itself. Additionally, professional cleaners have access to powerful cleaning agents that effectively break down chemical bonds between contaminants and surfaces giving your building renewed brilliance.

Weather Conditions

Effects of Sunlight Exposure:

Direct and prolonged sunlight can cause fading or discolouration on render finishes. This is because UV rays break down the pigments used in the rendering materials, causing them to fade over time.

Impact of Rainfall and Wind:

Rainwater carries dirt and pollutants that can cause biological growth, such as algae or black mould, on rendered surfaces. In addition to this, strong winds can carry debris which may scratch or damage the surface.

Seasonal Changes:

Temperature changes throughout different seasons also affect exterior building materials. Cold weather causes water to freeze within small cracks in a surface which expands as it freezes leading to larger cracks forming over time.

Cleaning techniques for restoring faded/discoloured render include soft washing with low pressure water mixed with cleaning solutions specifically designed for removing mould, mildew and other contaminants without damaging surfaces. Just Clean Property Care has expertise in using these techniques safely while delivering quality results without harming your property’s finish.

Mould and Mildew

Mould and mildew on render can be caused by biological growth, such as algae. This not only makes the building look unattractive with black spots but also causes damage to its structure over time. Prevention techniques for mould growth include keeping the building dry, well-ventilated and regularly cleaned to avoid stagnant water that could lead to dampness.

Removing existing mould from discoloured render requires specialized cleaning techniques that should be carried out by professionals. These methods involve using appropriate chemicals while taking care not to cause any further damage or discolouration. Regular cleaning is essential in preventing re-growth of mould and maintaining a pristine appearance of the building’s exterior.


Types of air pollutants affecting render colouration include black algae, biological growth, and pollution from nearby industries or traffic. These pollutants can cause discolouration on your home’s exterior surfaces over time. Here are some steps you can take to minimize the damage caused by pollution:

  • Regularly clean your render using a soft-bristled brush or low-pressure power washing
  • Use gentle cleaning products that won’t damage the surface of your render
  • Consider applying an anti-fungal treatment to prevent future growth

By taking these steps, you can keep your home’s exterior looking its best and avoid costly repairs in the future. Remember to consult with a professional if you are unsure about how to properly care for your property.

In addition, it is important to be aware of the impact that pollution has on our environment and take action where we can. By reducing our carbon footprint through actions such as carpooling or using renewable energy sources, we can help prevent further damage caused by pollution.

Bird Droppings

Bird droppings can be a nuisance to property owners as they can cause damage to rendered walls. The acidic content of bird droppings can lead to discoloured render and the growth of biological organisms such as algae. Preventive measures against bird infestations in properties include installing nets or spikes and sealing any gaps that birds may use for nesting. Proper cleaning and maintenance techniques involve using appropriate detergents, tools, and protective gear when removing bird droppings from rendered walls.

Cleaning Techniques for Discoloured Render

One effective cleaning technique to restore discoloured render is soft washing. This method involves using a low-pressure water stream and eco-friendly cleaning solutions to gently remove dirt, grime, and stains without damaging the surface. Soft washing is ideal for delicate renders that cannot withstand high-pressure cleaning methods.

Another option for restoring faded or discoloured render is chemical cleaning. This involves applying a specially formulated solution that breaks down tough stains and restores the original colour of the render. Chemical cleaning should always be done by professionals as it requires expertise in handling potentially hazardous chemicals safely.

Soft Washing

Gentle Cleaning Solutions are key to restoring discoloured render without causing damage to the surface. Our Soft Washing technique combines a low-pressure water application with effective cleaning solutions, making it perfect for delicate renders. This method is particularly useful for removing algae and moss growth which can cause discolouration over time.

The Low-Pressure Water Application used in our Soft Washing process ensures that your render is not damaged during the cleaning process. By using a gentle approach, we’re able to effectively remove dirt and grime buildup from your property’s exterior without risking any damage or harm to the surfaces being cleaned. Not only does this ensure a thorough clean, but it also helps prevent future erosion of your building’s surfaces due to high-pressure washing techniques.

Overall, our Soft Washing technique proves Effective for Delicate Renders and provides an excellent option for those looking to restore discoloured or faded render on their properties while ensuring they remain protected from further harm or deterioration. With Just Clean Property Care you can trust that we’ll use safe and effective methods that preserve the integrity of your property’s exterior surfaces while bringing them back to life.

Pressure Washing

High-pressure water application is an effective way of deep cleaning discoloured render. The technique involves using a powerful jet of water that can reach even the most stubborn stains and dirt build-up on your walls. With this method, you can expect to see clean, renewed surfaces in no time.

Pressure washing is best for robust renders that need heavy-duty cleaning. If your exterior walls have tough grime or mould build-up that cannot be removed with traditional methods, pressure washing might be the solution you need. This technique uses high-pressure water jets to blast away dirt and debris from the surface of your render quickly and effectively while still being gentle enough not to damage it.

Chemical Cleaning

Use of specialised chemicals is an effective way to remove stains and discolouration from render surfaces. Chemical cleaning works on all types of render surfaces, including concrete, brick, and stone. However, it requires professional handling as improper use can cause damage to the surface.

Chemical cleaning involves applying a solution containing specialised chemicals that break down dirt and grime on the surface. The solution is then rinsed off with water leaving behind a clean and brightened surface. Professional handling ensures that the correct concentration of chemicals is used for each type of render surface and prevents any damage during application or removal.

Overall, chemical cleaning offers an effective solution for restoring faded or discoloured render surfaces when handled by professionals using appropriate techniques.

Preventing Discolouration of Render

Regular cleaning and maintenance is crucial to prevent discolouration of render. Dirt, grime and pollutants can accumulate on the surface and cause fading or stains over time. By regularly washing the render with a gentle detergent and warm water, you can remove these contaminants before they cause permanent damage. Additionally, it’s important to inspect the render for any signs of damage such as cracks or gaps that could allow moisture to seep in.

Using protective coatings or sealants can also help prevent discolouration of render by providing an extra layer of protection against weathering, UV rays and other environmental factors. These products create a barrier between the surface and external elements that can cause colour fade or staining. However, it’s important to choose a coating that is compatible with your specific type of render material for best results.

Regular Cleaning and Maintenance

Maintaining the cleanliness of your render is crucial for its longevity. Regular cleaning extends the life of your render, as it prevents dirt and grime from accumulating on the surface, which can cause discolouration over time. This means that you won’t need to replace or repair your rendered walls as frequently.

When cleaning discoloured render, it’s best to use a gentle approach. Avoid using high-pressure sprays or harsh chemicals that may damage the surface. Instead, opt for low-pressure washing with warm soapy water and a soft-bristled brush. Rinse thoroughly with clean water afterwards.

It’s also important to identify potential issues with your rendered walls early on before they worsen into larger problems such as cracks or dampness in the interior walls of buildings adjacent to them. Keep an eye out for signs such as cracking or crumbling around window sills, mould growth near corners where there might be trapped moisture due to poor ventilation etc., so you can take action before things get worse!

Use of Protective Coatings and Sealants

Protective coatings and sealants are a simple but effective solution to restore faded or discoloured render. There are various types of protective coatings available in the market, including acrylic, silicone, or mineral-based sealers. Each type offers different benefits such as water-repellent properties or resistance to algae growth. It is important to choose the right coating based on your needs.

Before choosing a protective coating or sealant, you should first evaluate the condition of your render and identify any underlying issues that need to be addressed. This will help you determine which type of protection is best suited for your particular situation. For example, if your render is prone to cracking due to weather conditions, an elastomeric sealer may be more appropriate than a standard acrylic sealer. With proper selection and application of a suitable protective coating or sealant by professionals like Just Clean Property Care experts in this field can ensure long-lasting restoration for your discoloured/rendered walls while providing enhanced protection against future damage caused by environmental factors such as UV rays and moisture penetration through rainwater!

Choosing the Right Professionals for Render Cleaning

When it comes to restoring faded or discoloured render, choosing the right professionals is crucial. Expertise and experience should be on top of your checklist. Look for professionals who have a proven track record in this area, with testimonials from satisfied customers to back them up.

Quality equipment and materials are also essential factors to consider when choosing the right professionals for render cleaning in Cheshire. Make sure they use only high-quality products that will not cause any damage to your property. This ensures maximum effectiveness while maintaining safety precautions during the cleaning process.
