K-Rend is a versatile substrate available in a wide variety of colours, but once contaminated with organic growth it can be difficult to restore. Get expert cleaning that won’t damage your home.
The inclement UK weather leads to a build up of organic growth on K Rend substrates. This is can the form of single cell green algae, a red algae known as Trentopohlia, lichens, moss, and a variety of moulds.
Black moulds like Geo-capsa Magma and Aspergillus Niger are very common.
These all require specialist treatment to remove. Cleaning K-Rend is tricky, and harsh methods can ruin your render.

Softwashing Uk treats every job as its own individual project, as such, the most suitable method will be proposed in our quotation. Over the many years we have been restoring render, we have found that the cleaning of it falls in to five categories:
This service is used when the render has not been cleaned for many years and the render is heavily stained with black mould, blackspot and lichens, as per the sliding photograph.
This method requires every square inch of the render to be low-pressure washed, or steam cleaned and treated with stain remover, multiple times to achieve the desired finish.
This service is our render restoration service above, followed by our biocide render
treatment service, below in point 5.
This service is for your day-to-day cleaning of render, that has average organic staining i.e. green, red and some black staining in areas. An example of this is showed in the
photographs.
This service is for your day-to-day cleaning of render which is followed by a biocide
treatment, to help keep the render cleaner for longer.
The application of a high quality HSE approved professional use only biocide. A biocide
treatment will help keep render looking clean, while reducing the need for more intensive
and expensive render restoration cleaning, at a later date.
Specialist biocide treatments for render are essential for maintaining the appearance and durability of render. Homeowners often underestimate the impact of weather on render. Over time, harsh conditions can lead to cracks, discolouration, and mould growth.
Applying anti-fungal solutions, prevents mould and algae growth. It’s crucial to address these problems early, as they can worsen over time.
Our professional-grade biocide acts fast against biological growth on all external hard surfaces, breaking the reproductive cycle of microbial surface contaminants.
K-Rend is a popular modern render finish used on homes and buildings across the UK for its clean appearance and long-lasting protection. However, over time, K-Rend surfaces can become stained and discoloured due to algae, moss, lichen, and general pollution. That’s where Softwashing UK comes in.
We offer professional K-Rend cleaning using specialist soft washing technology — a safer, longer-lasting alternative to high-pressure washing.
Unlike pressure washing, which can damage render surfaces and void warranties, our low-pressure soft wash system uses biodegradable cleaning solutions designed specifically for delicate surfaces like K-Rend.
It penetrates the porous render to kill algae, moss, and biological growth at the root, without damaging the finish.
Our soft wash method not only restores the appearance of your K-Rend but also eliminates the spores and microbes responsible for discolouration.
This provides a longer-lasting clean, reducing the frequency and cost of future treatments.
We do more than clean — we treat and protect. Our solution includes a biocidal treatment that destroys moss, lichen, and algae at the source, preventing regrowth and helping maintain your render’s pristine appearance.
Pressure washing can crack or erode render surfaces.
Our soft wash system is gentle enough for even the most delicate finishes, while being powerful enough to remove years of grime, pollution, and organic staining.
