A Guide to Render Cleaning in 2023


Are you struggling to keep your property or the exterior of a property you manage looking fresh and clean? Render cleaners are essential for maintaining the appearance and value of your home or commercial building. We’ll explore the importance of regular render cleaning, various techniques, and considerations for different types of render. Let’s embark on a journey to unveil the secrets of effective render cleaning with the help of render cleaners!

Short Summary


The Importance of Render Cleaning


 Preserving the aesthetic and monetary value of a home or commercial building is of utmost importance for property owners and property managers. Render cleaning plays a crucial role in avoiding deterioration and discolouration caused by algae and dirt.

With various types of render available, such as textured and smooth finishes, coloured or pebbled render, cement, lime, and clay render, it is essential to understand the specific needs of your property to maintain its curb appeal.

The Effects of Green Algae and Dirt on Rendered Surfaces


Rendered surfaces are prone to staining, damage, and decreased property value due to:

These factors contribute to staining and discolouration on render surfaces.

Neglecting fungus growth on rendered surfaces can lead to considerable damage, so it’s essential to address these issues promptly and effectively.

Preventing Damage and Discoloration


To prevent damage, discolouration, and the need for expensive repairs, it’s crucial to maintain regular render cleaning using appropriate cleaning chemicals. For delicate surfaces, soft wash cleaning methods are recommended.

At Spectrum we have cleaned over 600 commercial properties using our unique PAST process of cleaning and restoring render.

If algae has caused extensive discolouration, it’s best to seek the services of a professional render cleaning company for an alternative treatment and a light steam clean instead of using a jet or pressure washer.

Render Cleaning Techniques: Soft Washing vs Pressure Washing


 When it comes to render cleaning, there are two primary techniques: soft washing and pressure washing. Both methods have their pros and cons, so it’s essential to understand the differences and choose the one that best suits your property’s needs.

Soft washing is gentle and doesn’t damage the building’s substrate, while pressure washing can be more effective at eliminating persistent dirt and grime. Let’s delve deeper into these techniques to help you make an informed decision.

Soft Washing: A Gentle Approach


Soft washing is a low-pressure cleaning technique that uses jet sprays and nozzles to clean rendered walls effectively without causing any damage. It’s a less intrusive method compared to high-pressure washing and doesn’t cause harm to rendered walls.

Soft washing is ideal for cleaning K rend and other delicate render surfaces with a mild detergent. The gentle nature of soft washing ensures an even, pristine finish that will leave your property looking its best.

Pressure Washing: When to Use It


Pressure washing is a powerful cleaning method that can be used to quickly remove dirt, grime, and other contaminants from outdoor surfaces such as driveways, decks, and siding. However, caution should be exercised when using pressure washing for render cleaning, as incorrect use can lead to damage of surfaces, including painted surfaces if the pressure is too high.

In some cases, pressure washing may be appropriate for large areas or stubborn dirt, but it’s essential to use the correct technique and equipment to avoid potential harm.

Render Cleaning Techniques: How We Do It at Spectrum


Whilst jet washing and softwashing will get you results we have found that it doesn't deliver the quality of results our clients are looking for. After years of maintaining modern render and cleaning over 700 rendered facades we have come up with a four stage process that is non abarasve and has helped us transform the face of buildings across the uk.

After spending over 250K in new reseach and development around render and the maintenance implications and options we dvised a four stage non abarasive process. We train all of our staff in the full PAST approach. Let us tell you some more about it.

P.A.S.T: The ultimate method for cleaning render.


PAST is a four stage treatment and includes the following steps:

P = Planning and preparation
A = Application of biocide
S = Steam *the most important part
T. =Targeted treatments and retreatment of the process where necessary.


We have used this PAST process to transform hundreds of buildings across the UK.

As a property manager, continual upkeep of the properties in your portfolio is crucial.

Warranties and building insurance generally stipulate the necessity of proper building maintenance.

Should damage occur to a property's render that necessitates repair, the rendering manufacturer or building insurance provider may decline to cover the cost if they perceive negligence by the property manager.

To preserve the quality of your properties, it's advised to schedule render cleaning at least annually.

Routine render cleaning not only allows you to identify and swiftly address necessary repairs, but also enhances the aesthetic appeal of your property.

Choosing the Right Render Cleaning Chemicals


Selecting the right render cleaning chemicals is crucial for effectively eradicating algae growth and enhancing the appearance of the render without causing any harm. Various render cleaning chemicals are available in the market, so it’s essential to choose eco-friendly and biodegradable options that won’t harm your property or the environment.

Let’s explore these options further.

Biodegradable and Eco-Friendly Options


Using biodegradable and eco-friendly cleaning chemicals is a responsible choice, as it reduces the risk of damage to your property and the environment however it is not always possible to acheive the desired result. Some popular options include:


These chemicals are cost-effective and easy to use, making them an ideal choice for both residential and commercial properties.

Avoiding Harsh Chemicals


It’s vital to avoid harsh chemicals that can damage and harm the environment. Utilizing harsh cleaning chemicals for render cleaning can detrimentally impact the render, potentially cause skin irritation upon contact, and negatively affect the environment.

Therefore, it is imperative to use eco-friendly and biodegradable cleaning solutions to mitigate these risks.

Types of render brands we can clean


There are many different render brands that all seem to have their own special methods for maintaining render. We have cleaned every single one of them and nothing works better than the P.A.S.T method taken by Spectrum.

Weber render cleaning


Weber render products are successfully manufactured to produce high standards and durable finishes.

However, in order to ensure this rendered coating continues to look as impressive as it should, you're going to need a render cleaning service at some point.

There are many render manufacturers that communicate in very different ways to maintain and restore render. This can make it all extremely confusing.

If you are not sure your rendered building can be cleaned, our team can happily carry out a free sample to show you the possible outcome.

K-rend render cleaning


K- Rend render is mineral-based and processed using limestone, providing a natural-looking finish.

However, even though k-rend is renowned for its durability, it's not invincible to the harsh elements that the weather can impose.

Render cleaning without professional expertise can cause irreparable damage to the substrate. It's very important that you choose a contractor that understands the properties of each type of render in order to treat it correctly.

K-Rend needs a specially formulated cleaning solution, gently applied with a specific method to effectively kill the algae and spores to prevent future re-growth.

Our P.A.S.T. process is designed to clean and restore K-rend render to a like-new condition with no risk to the substrate.

Monocouche render cleaning


The word 'monocouche', in French, simply translates to 'one coat.'. As this brand traditionally applies its render in two parts, bonded together and forming one strong coating.

Moncouche render is cement-based that provides a breathable and durable surface.

Our team of experts teach surveyors and property managers through our CPD programme how to best maintain each render type. So rest assured you will be in the safest hands.

Sto render cleaning


Known for their award-winning high-quality render finishes, Sto is another popular render manufacturer.

Keep your Sto render looking its best all year round by choosing Spectrum as your render cleaning contractor.

Wetherby render cleaning


Wetherby Building Systems Ltd has been in the render manufacturing industry for years now, offering a range of render and brick slip systems.

Now when it comes to cleaning and maintaining your Wetherby render, it's essential that your chosen contractor has a certain degree of care and the correct equipment.

Not only is our render cleaning team experienced with an eye for detail, but they're also IRATA trained. This means that there's no need for scaffolding and the risk of damage (from erecting the set-up and then taking it back down) is avoided.

Parex render cleaning


Parex is another popular render brand that is renowned for its quality and seamless finish.

Many render manufacturers communicate about lots of different ways to maintain render and it can become very confusing.

No matter what brand of render you have, Spectrum has the cleaning solution.

if you find yourself thinking that your render can't be cleaned, reached or restored, then get in touch with our team and we will happily carry out a free sample to show you the possible outcome.

Professional Render Cleaning Services: What to Look For


 If you’re considering hiring a professional render cleaning service, it’s essential to look for experience, accreditation, and tailored solutions for your property. An experienced and accredited render cleaning service guarantees safety, quality work, and peace of mind.

Let’s explore what to look for in a professional render cleaning service.

Experience and Accreditation


Choosing a render cleaning service with experience and accreditation ensures quality work and peace of mind. Accreditation guarantees that the render cleaning service is competent and proficient in the domain and utilizes the most up-to-date techniques and technologies to deliver optimal results.

Experienced render cleaning services possess the expertise and knowledge to detect and address potential issues before they become serious, ensuring the best results for your property.

We recommend looking into case studies the company shares, these will give you a huge insight into the companies credibility. If you want to review all of our render cleaning projects take a look at our render cleaning case studies.

Tailored Solutions for Your Property or the properties you manage.


It’s essential to find a clean render cleaning service that offers tailored solutions for your specific property and render type. Tailored solutions can offer an improved and streamlined cleaning process, safeguard the render from harm, and prolong its lifespan.

Whether you have a residential property or a commercial building, a professional render cleaning service that caters to your unique needs will ensure the best outcome.

DIY Render Cleaning: Proceed with Caution


 While DIY render cleaning may seem like a cost-effective option, it’s essential to be aware of the risks and challenges involved, including inadequate equipment and improper technique.

If you’re considering DIY render cleaning, proceed with caution and ensure you’re using the right equipment and techniques to avoid damaging your property.

Risks of Inadequate Equipment


Using inappropriate equipment for render cleaning, such as high-pressure washers or harsh chemicals, can result in damage, discoloration, and expensive repairs. It’s crucial to invest in the right equipment and use gentle methods, such as soft washing or hand cleaning, to avoid potential harm to your property.

Soft washing is a low-pressure cleaning method that uses a combination of detergents and water.

The Importance of Proper Technique


Using proper techniques when attempting DIY render cleaning is essential to avoid damage and achieve the best results. A low-pressure spray or soft wash with an appropriate cleaning solution and adjusting the nozzle to a fan action is suggested by many professionals but this process does not provide a lasting finish.

The PAST approach used by the Spectrum team has been developed over years of cleaning render. With four stages P.A.S.T it esnures that you get the best possible result from your render clean every single time. Our team are trained in the full P.A.S.T approach.

Regularly cleaning your render as soon as any organic or pollutant stains appear and at least annually will ensure the longevity and aesthetic appeal of your property.

Coloured Render: Special Considerations

Coloured render requires special attention and care when it comes to cleaning. Choosing the right cleaning process and understanding the differences between very light jet washing and soft washing is crucial to maintaining the appearance and preventing damage to your coloured render.

Let’s explore these special considerations in detail.

Choosing the Right Cleaning Process


Selecting the appropriate cleaning process for coloured render is essential to prevent damage and sustain the aesthetics of your property. Power or jet washing with clean water and a low concentration of mild detergent is an option.

Mixing in Green Wash is also an option. Green. Green. Wash has been formulated for a specific purpose: to be mixed with bleach in order to clean stained render. It can be used as a powerful cleaning agent when combined with bleach.

Very Light Jet Wash vs Soft Washing


Very light jet washing is a low-pressure technique of cleaning render that utilises a jet of water to eliminate dirt and debris. While it can be efficient in cleaning render, it may not be the most suitable approach for cleaning coloured render that has algae growth on it.

The jet wash can cause significant damage to a building if in the wrong hands. We have been called to support with many commercial rendered buildings where inexperienced contractors have simply turned up the pressure in order to try and get a pristine finish and in doing so actually cut through the layers of the render causing irreversable damage.

Soft washing is a gentle method that employs a combination of detergents and water to remove dirt and debris, making it more suitable for coloured render, howver you will find that simply softwashing will not result in a pristine finish especially where you have areas of heaving staining from carbon staining, pollution, graffiti or severe algae growth.

take a look at a recent project of ours which involved cleaning and restoring coloured render on a block of flats for a housing association.

Render Cleaning for Different Building Types


Render cleaning is not a one-size-fits-all approach, as different building types may require unique considerations and techniques. In this section, we’ll discuss render cleaning for residential properties and commercial buildings, highlighting their specific requirements and challenges.

Residential properties often require a gentler approach to render cleaning, as the materials used are expensive.

Residential Properties


Residential properties often require special attention to maintain curb appeal and prevent damage caused by dirt, algae, and other contaminants. It’s essential to avoid pressure washing and instead utilise gentle cleaning methods such as hand cleaning or soft washing with a bleach solution for residential render cleaning.

Soft washing is a low-pressure cleaning method that uses a bleach solution to remove dirt and algae.

Commercial Buildings


Commercial buildings have unique requirements and considerations for render cleaning, including maintaining a professional appearance and adhering to safety regulations. Non-aggressive cleaning techniques such as soft washing and steam cleaning are suggested for render cleaning of commercial buildings to avoid potential damage to the rendered surface.

Soft washing is a low-pressure cleaning method that uses a combination of detergents and water.

If you want to see us at work here are a few of our recent commercial render cleaning projects: 

Summary


In conclusion, regular render cleaning is vital for maintaining the appearance and value of your property, whether it’s a residential home or a commercial building. By understanding the different types of render and the approproate cleaning techniques you can make better decisions for your properties.Remember to consider the unique requirements of your property don't hesitate to reach out if you need our help.

The Different Types Of Modern Render

Acrylic
Based Render

Acrylic render is one that uses acrylic (a sort of plastic) in the mix, and this, in turn, makes this render strong, flexible, and less likely to crack or flake and the pigment/colour of it is well lasting.

Acrylic render is a versatile option as its also suitable for a range of different surfaces, such as:

  • Concrete
  • Painted Walls
  • Timber
  • Brick
  • Stone

However, due to the strength and tight seel of acrylic render, this compound is less 'breathable' (in comparison to Silicone Render).

The following brands manufacture acrylic render: Wetherby, K-Rend, Parex, and Eco-rend.

Silicone
Based Render

Silicone-based render is made from...silicone. Silicone is basically a polymer that's rubbery and heat-resistant.

In comparison to acrylic render, it doesn't impede breathability. Yet, this improvement does come at a cost.

This render type has great flexibility (unlikely to crack) and is highly durable (with paint required after 10 years).

Silicone render is a more costly option and involves four different stages of application - it's not the quickest alternative.

JUB Render, K-Rend and Wetherby all manufacture silicone-based render.

Cement
Based Render

Cement render is composed of three different elements: lime, sand and of course cement.

This type of render is breathable and cost-effective - allowing you to render large areas without breaking your budget.

However, cement render is not suitable for all surfaces (commonly used only for bricks) and may also be prone to cracking.

Here are some cement-based rendering manufacturers: EZ Design and Construction, Wetherby, and K-Rend.

Wetherby Building Systems Ltd has been in the render manufacturing industry for years now, offering a range of render and brick slip systems.

Now when it comes to cleaning and maintaining your Wetherby render, it's essential that your chosen contractor has a certain degree of care and the correct equipment.

Knowledge and Experience

Cleaning render is a very complicated process – even though we make it look easy. There are many types of render and varying stages of soiling. The state and type of render determines what method and products will be used to carry out the clean safely and effectively.

Using the wrong chemicals or a jet wash can cause significant damage to your building, and may invalidate any warranties you may have. We use our extensive knowledge to carry out a survey of your render. We establish what products have been used and the best methods to produce a clean finish.

Below are some of the main types of render than we work with, and the best ways to achieve a clean finish when working with them.

K-Rend Cleaning

We can clean all K-Rend render using specialist products designed especially for our P.A.S.T. process.

Silicone Render Cleaning

We can clean all silicone render using specialist products designed individually for each job.

Monocouche Cleaning

We can clean all Monocouche render, again using specialist products designed for work with this kind of render.

Other types of render that we can work with include Weber, Stowe and Wetherby. Here at Spectrum we pride ourselves on being able to clean any manufacturer’s products using our softwashing render technique, producing a stunning finish that makes your building look good.

We will carry out a full site survey to assess the type and condition of your building’s render before any work is agreed to. During this visit, we will choose an appropriate biocide for the fabric of the render. We will then make sure that it is mixed in the correct ratios and add in appropriate catalysts depending on the type and amount of algae and dirt.

The biocide works into the render, killing all algae and any other living organisms. The render is then gently steam washed with an industrial DOFF steam cleaning machine to ensure the algae is completely removed. We always ensure the best steam cleaning machines are used, as this can make a big difference to the overall finish.

If you would like to know more about our render cleaning services, or to book a site inspection to assess your render, get in touch with a member of our team. External wall cleaning and render restoration are just some of the services we offer to keep your buildings looking in the best possible condition.
