When K-Rend and silicone-based renders start showing ugly red algae, black mold, or environmental staining, aggressive high-pressure washing often causes expensive surface damage. Mr Softwash delivers a specialized, low-pressure softwashing solution designed specifically to restore render without compromising its structural integrity. By combining gentle water pressure with targeted, eco-friendly biocide treatments, Mr Softwash sanitizes surfaces at the root level—killing organic growth rather than just blasting away surface dirt. Mr Softwash’s specialised non-abrasive method kills the biofim contaminating your render and guarantees a longer-lasting clean, protecting your property’s curb appeal and preserving your render from further contamination for 3-5 years.

Has your once bright K Rend started to turn green, black or patchy?
Algae, mould, lichen and airborne pollution can quickly spoil the appearance of modern render, particularly on shaded or north-facing walls. While K Rend is designed to be durable and low maintenance, it is not maintenance free.
At Mr Softwash®, we specialise in safely restoring K Rend using professional soft washing techniques that clean the surface without the risks associated with high-pressure jet washing.
Why Does K Rend Become Stained?
K Rend is a through-coloured silicone render designed to repel water while allowing the building to breathe.
Over time, however, moisture, airborne spores and environmental pollution create the perfect conditions for biological growth.
Common causes include:
- Green algae
- Black mould staining
- Red algae
- Lichen
- General atmospheric pollution
- Coastal salt deposits
- Shaded or damp elevations
These contaminants continue to grow if they are simply washed from the surface.
Why Pressure Washing Can Damage K Rend
One of the biggest mistakes homeowners make is attempting to clean K Rend with a pressure washer.
Although dirt may disappear temporarily, excessive water pressure can:
- Damage the textured finish
- Strip the protective surface
- Force water behind the render
- Cause cracking or blown render
- Leave permanent patchy marks
Because K Rend is typically only around 8–10mm thick, using excessive pressure can create expensive repair work that could easily have been avoided.
The Safe Way to Clean K Rend
Soft washing is recognised throughout the exterior cleaning industry as the safest and most effective method for cleaning modern renders.
Instead of relying on pressure, we apply specialist cleaning solutions at very low pressure.
These treatments:
- Kill algae at the root
- Remove mould and organic staining
- Eliminate spores that cause regrowth
- Clean evenly without damaging the render
- Leave your property looking brighter for longer
Unlike pressure washing, soft washing treats the cause of the problem rather than simply removing what you can see.
Our K Rend Cleaning Process
Every property is different, which is why every project starts with a full assessment.
1. Inspection
We inspect the render for staining, cracking, previous repairs and contamination.
2. Surface Assessment
We assess the condition and absorbency of the render to determine the safest cleaning method.
3. Soft Wash Application
A specialist soft wash solution is applied using low-pressure equipment to penetrate organic growth without damaging the surface.
4. Controlled Dwell Time
The cleaning solution is allowed time to work deep within the contamination.
5. Low-Pressure Rinse
The render is gently rinsed, revealing a clean, even finish.
6. Long-Term Protection
Where appropriate, we apply a professional biocidal treatment to inhibit future algae growth and help keep your render cleaner for longer.
How Long Will the Results Last?
Every property is different.
Factors such as nearby trees, shade, coastal exposure and moisture levels all affect how quickly algae returns.
In many cases, our biocidal treatment helps keep K Rend looking cleaner for several years before another maintenance clean is required. Regular maintenance significantly extends the life and appearance of modern render.

Frequently Asked Questions
Can K Rend be pressure washed?
We do not recommend high-pressure cleaning on K Rend. Soft washing provides a far safer and longer-lasting solution for removing algae and organic staining.
Will the algae come back?
Eventually, yes. All exterior surfaces are exposed to the weather. However, professional biocidal treatment dramatically slows regrowth compared with pressure washing alone.
Is soft washing safe?
Yes. When carried out correctly by trained professionals, soft washing is specifically designed for delicate rendered surfaces.
How often should K Rend be cleaned?
Most homes benefit from professional cleaning every two to five years, depending on location, shade and surrounding vegetation.

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!
