HBS GoRend Monocouche render is a popular choice for new-build properties due to its consistent quality, durability, and vibrant, long-lasting colour.
This factory-produced render is entirely through-coloured, meaning it retains its colour for years without fading. Ideal for finishing multiple properties with the same colour and standard, it doesn’t require a basecoat application, reducing both time and construction costs.
It can be applied by hand or machine to blockwork and is breathable, ensuring healthy, damp-free building interiors. HBS GoRend Monocouche render is also highly weather-resistant and durable.
Even though HBS GoRend Monocouche render is designed to maintain its colour, external factors like organic growth can impact its appearance over time. For example, black mould and algae can colonise the surface, diminishing its look. In this case study, you’ll see how black mould invaded the render, reducing its aesthetic value.
While black mould is often the most noticeable contaminant, it doesn’t appear on its own. Initially, less complex algae, often green or red, establish themselves first. These algae create the ideal environment for black mould to thrive. Once black mould appears, it’s crucial to act promptly—leaving it untreated can not only harm the render’s appearance but also cause long-term damage to the substrate beneath.

Restoring your HBS GoRend Monocouche render to its original condition is simple with the right cleaning method. Algae and light stains can be treated effectively using soft washing, a gentle, non-invasive cleaning method that uses steam and a biocidal solution to remove the contaminants. For more stubborn black stains, specialist cleaning treatments combined with steam are recommended. It’s important to fully rinse the treated areas after using chemical cleaners to remove salts and other compounds that could encourage future re-colonisation.
In our video case study, the HBS GoRend Monocouche render was cleaned and restored from the safety of the ground using extendable poles. Additionally, the slate flooring was also restored to its original condition.
If your HBS GoRend Monocouche render has been affected by organic growth or discolouration, contact Softwashing UK today for a no-obligation quote to restore its beauty and durability. Let us help you maintain your render’s long-lasting, vibrant appearance.

























Apartment blocks face constant exposure to the elements — rain, wind, pollution, and biological growth such as algae and moss. Over time, this leads to staining, discolouration, and potential structural issues that impact both the appearance and long-term condition of the property.
A neglected exterior can lower kerb appeal and reduce property value. That’s where Softwashing UK comes in.
We provide professional apartment block cleaning and restoration using our specialised soft wash technology — a safe, effective, and long-lasting alternative to harsh, high-pressure methods.
High-pressure washing can damage exterior surfaces, strip coatings, or drive water into vulnerable areas. Our soft wash system uses low-pressure techniques and biodegradable cleaning agents to safely remove dirt and contaminants without harming the building fabric.
Our softwash treatment eliminates algae, moss, lichen, and other organic matter at the source. This not only removes visible staining but also prevents regrowth, keeping apartment blocks looking fresh for longer and reducing the need for repeat cleaning.
We don’t just clean the surface — we restore it. Our biocidal solutions penetrate porous surfaces like render, brick, cladding, and stone to lift stains, kill growth, and remove pollutants, restoring the building’s original appearance.
Left untreated, moss, algae, and pollutants can hold moisture against surfaces, leading to cracks, water ingress, or costly repairs. Regular softwash cleaning preserves the integrity of render, masonry, and paintwork, extending the lifespan of your building.
Our expert team is fully trained in safe building access, softwash application, and chemical safety. We are insured and experienced in working on apartment blocks of all sizes, including high-rise developments and complex façades.
Our cleaning solutions are pH-neutral, biodegradable, and eco-friendly. They are safe for residents, landscaping, and drainage systems, with no harmful runoff — ideal for environmentally conscious property managers and housing associations.
We offer flexible scheduling to minimise disruption, including early mornings, evenings, and weekends. Our efficient, quiet methods ensure residents can go about their day while we restore the building exterior.
A clean, well-maintained apartment block projects pride of ownership, improves kerb appeal, and reassures residents and potential buyers alike. Whether preparing for inspections, new tenants, or simply maintaining high standards, our service adds visible value and long-term protection.

Thank you very much!Posted on Paul WelshTrustindex verifies that the original source of the review is Google. We’ve used Softwashing a number of times over the past few years to clean the exterior of our house, gutters and patio. Every time it has been a fantastic service, always going above and beyond, whether it’s attacking a stubborn rust stain or taking time to explain the process. We have recommended them to friends and neighbours and using them every year is testament to how happy we are with the work they do. Thanks!Posted on Andrew CovellTrustindex verifies that the original source of the review is Google. The service was great, Gavin arrived on the dot of eight o’clock and he then talked me through the process before starting. He worked diligently using a range of different techniques to address the various issues. At the end the render looked like new! Would definitely recommend and will have them back again when it needs doing again!Posted on Peter GrantTrustindex verifies that the original source of the review is Google. As a director of and on behalf of Wardour Court Management Company and residents I wish to record our thanks to Gavin and his team. The property is a sensitive building constructed of Chilmark stone, it had not been cleaned for some time and was looking the worse for wear. They were all extremely efficient and professional as well as very pleasant and easy to talk to despite the difficulties they encountered, which included having to work 17 hours on one of the days. All the residents I have spoken to have expressed how pleased they are with the result, as are the directors of Wardour Court Management Co. We would happily use this company again and are equally happy to recommend them to others.Posted on Ann Grant JewelleryTrustindex verifies that the original source of the review is Google. Gavin and his team recently cleaned the Chilmark stone courtyard mews where I live. The stone was in dire need of cleaning and proved to be a very difficult job including one 17 hour day. Despite the difficulties he and his team remained pleasant, friendly and very professional leaving us with what I can only describe as a transformation ... our ugly duckling has become a swan. I can't thank them enough for their dedication and would happily recommend him and his company.Posted on City Stays sw LtdTrustindex verifies that the original source of the review is Google. One of our properties, which is a rental, was a complete eye sore on the exterior surfaces, which needed rectifying before it was able to go back on the rental market. After ringing around different companies, Softwashing UK stood out and understood our requirements. Softwashing UK Soft wash cleaned 15 years' worth of bad organic staining from our K-Rend render, brickwork, and all rain water goods to the property. We honestly could not believe the results that were achieved. The render now looks like the day we had it rendered. On the day of the work ne carried out, the guys turned up on time and carried out the job respectfully and professionally. It's great to see good tradesmen still exist. We highly recommend the soft wash service they offer, and we will be sure to recommend Softwashing UK our friends and family's.Posted on James CTrustindex verifies that the original source of the review is Google.
