K Rend Algae Cleean is K Rend's own recommended product to clean K Rend render.
K Rend Algae Clean (also marketed as K Rend Render Clean) is a specialized, water-based, antibacterial fungicidal wash designed to safely eliminate green and red algae, mould, lichen, and mildew from exterior rendered walls and hard surfaces. Formulated specifically to safeguard sensitive through-coloured monocouche renders, this solution works by killing organic growth at the root and continuously protecting the surface from quick re-infection without requiring damaging high-pressure washing or aggressive hand scrubbing.
Key Specifications & Performance
- Coverage: Covers approximately 12.5–25 m² per 5L bottle depending on surface porosity, or up to 98 m² when properly diluted with water.
- Action Time: Visible results typically appear within 3 days of application, continuing to self-clean and clear away organic debris over 2 to 4 weeks through regular weather cycles.
- Eco-Safety: It features an environmentally friendly composition that will not harm nearby lawns, grass, or plants if accidental overspray occurs.
- Application Frequency: Recommended as a preventative maintenance treatment every 6 to 12 months to keep render completely clear of biological staining.
Safe Step-by-Step Application Guide
To clean your K Rend walls cleanly without risking streaking or surface abrasion, professional exterior softwash technicians follow these steps:
- Pre-Inspect the Surface: Check the walls for deep cracks or structural damage that could take in moisture incorrectly before wetting the area.
- Protect Surrounding Areas: Drench nearby garden foliage, flower beds, and grass with clean water prior to application. This dilutes any chemicals that drift onto your plants.
- Mix and Apply: Dilute according to instructions and apply evenly using a low-pressure sprayer, brush, or roller, working in manageable, overlapping horizontal sections to avoid faint untreated lines.
- Dwell and Weather: Let the chemical sit on the surface for its specified dwell time. The solution requires no aggressive scrubbing and will continue to work over the coming days as it responds to rain and wind.
- Gentle Rinsing: If an immediate rinse is needed, use a standard garden hose or a pressure washer restricted to a wide fan tip at low pressure. Avoid high-power pinpoint streams which can permanently score or wear down the render texture.

5 Star Review
Steve at Mr Softwash did a brilliant job bio-cleaning the render on the exterior of our house. It took about 4-6 weeks to see the full results, and the house now looks like new again. In fact, when our neighbor commented on how good our house looked, so we recommended Steve to him, and Steve did an equally great job on his house. When our house needs another clean, we will be using Steve again without hesitation.

K Rend Cleaning | Professional Render Cleaning Specialists | Mr Softwash
K Rend is one of the UK's most popular render systems, giving homes and commercial properties a modern, low-maintenance finish. However, over time even the highest-quality render can develop green algae, black staining, moss and lichen due to the UK's damp climate.
At Mr Softwash, we specialise in the professional cleaning of K Rend, silicone render and monocouche render using safe, low-pressure soft washing techniques. Our process restores the appearance of your property without the risks associated with high-pressure washing, helping to protect your investment and improve kerb appeal.
Whether your render has become discoloured, covered in algae or simply lost its original appearance, our experienced team can provide a tailored cleaning solution.
Why Choose Mr Softwash for K Rend Cleaning?
Render cleaning requires specialist knowledge. Every render system has different characteristics, and using the wrong cleaning method can cause permanent damage.
Our soft washing process is designed to safely remove:
- Green algae
- Black mould and staining
- Moss
- Lichen
- Atmospheric pollution
- Organic staining
We carefully assess every property before selecting the most appropriate cleaning method.
Our Process
- Property inspection
- Identification of render type
- Application of specialist cleaning solution
- Low-pressure soft washing
- Professional biocide treatment
- Final inspection
This process not only restores the appearance of your render but also helps slow the return of biological growth.
Why Does K Rend Become Dirty?
Many homeowners believe render simply becomes dirty with age.
In reality, most staining is caused by biological growth rather than dirt.
Common causes include:
- Damp conditions
- North-facing walls
- Trees and surrounding vegetation
- Poor airflow
- High humidity
- Moss and algae spores
Early treatment prevents staining from becoming deeply established and helps maintain the appearance of your property.
Safe K Rend Cleaning
One of the most common questions we receive is whether K Rend can be pressure washed.
Modern render manufacturers generally recommend avoiding aggressive high-pressure cleaning because excessive force can damage textured finishes and reduce the lifespan of the surface.
Instead, Mr Softwash uses carefully controlled soft washing techniques that clean effectively while protecting the render.

Frequently Asked Questions
How long does K Rend cleaning last?
This depends on your property's environment. Homes surrounded by trees or with north-facing elevations may experience regrowth sooner than properties in open, sunny locations. A professional biocide treatment helps slow the return of algae and moss.
Does soft washing damage render?
No. When carried out correctly, soft washing is a low-pressure cleaning method specifically designed for delicate exterior surfaces such as modern render.
Can all render types be cleaned?
Yes. We clean a wide range of render finishes, including:
- K Rend
- Silicone render
- Monocouche render
- Acrylic render
- Mineral render
- Painted render
Each surface is assessed before cleaning to determine the most suitable treatment.
Will all stains disappear?
Most biological staining can be removed successfully. The final result depends on factors such as the age of the staining, the condition of the render and any previous damage. We provide honest advice during our initial assessment.

I cannot recommend Steve at Mr Softwash Ltd highly enough. A very professional job done on our patio - paving slabs which hadn’t been cleaned for 4-5 years! They now look amazing and no mess left. My request for a quote was responded to quickly and he turned up at the date and time he said he would. Very happy customer 😊
Steve has soft washed my house and it was an excellent job. He's just come back and jet washed the driveway and resanded it and has done yet another excellent job. I highly recommend his work.
I can totally recommend Steve. We had our blocked drive and patio cleaned.Both came up as new.
Steve is prompt , efficient and takes pride in his work. Steve keeps you informed on everything he is doing and why.
It’s lovely to get such good service.
Excellent workmanship, highly recommend. Did front drive and large patio at rear, totally satisfied with all that was done. Thankyou Margaret
5 star service!
We got in touch with Steve after an accident with a large pot of green fence paint that exploded all over our block paved driveway! Steve was brilliant from start to finish, he cleaned our driveway, path at the front of our property and our Indian sandstone patio in the garden and has done a top job! All 3 areas look brand new, the paint has completely gone and its transformed the outside of our little house. Can’t rate Steve’s service highly enough. Professional, friendly and he’s done a brilliant job. Thank you!
I've just had my block paved Driveway cleaned and resanded by Steve at Mr Softwash Ltd...and I am chuffed to bits with it! It was in a right sorry state after a Massive Water leak restoration by Insurance builders, it had mould,Moss, water stains, builders rubble, tile grout, concrete you name it, it was on there!..and Now after he worked his magic, looks like it was laid yesterday. Pristine and all the colours are back and refreshed.
Steve was prompt, his work was clean and efficient, and he told me at every stage from estimate, to end of job why and how he was going to do job. I am extremely Happy with the Work carried out and would recommend this company to anyone!!
Thank you Mr Softwash Ltd!
