K-Rend Problems - Cleaning K-Rend with Softwashing

K-Rend Softwashing Cleaning Company

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.

Why Choose Softwashing UK For K-Rend Cleaning Services?

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.

Specialised Soft Wash Technology
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.
Longer-Lasting Results
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.
Moss, Lichen & Algae Control
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.
Gentle on Surfaces, Tough on Staining
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.
Fully Trained & Insured Technicians
Choosing Softwashing UK means choosing experienced, fully trained, and insured professionals. Our team understands how to clean K-Rend properly and is certified in softwashing methods, chemical handling, and exterior property care.
