K Rend Cleaning Specialists
Safe, Professional K Rend Cleaning Across Broadstone, Dorset.
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 Broadstone
K Rend Cleaning Broadstone
Professional K Rend Cleaning in Broadstone, Dorset
Is your K Rend looking green, black, stained or patchy?
At Mr Softwash®, we provide professional K Rend cleaning in Broadstone, Dorset, using specialist soft washing techniques designed to clean modern rendered surfaces without the need for aggressive pressure washing.
K Rend is a popular choice for homes because of its attractive, textured finish and weather-resistant properties. However, even good-quality render can become marked by algae, mould, lichen, dirt and atmospheric pollution.
Over time, these contaminants can leave your Broadstone home looking tired and neglected.
Our specialist soft washing process is designed to remove this organic growth and restore the appearance of your K Rend safely and effectively.
K Rend Cleaning Specialists in Broadstone
K Rend can be particularly susceptible to green algae and black staining where walls are exposed to moisture, shade and limited sunlight.
North-facing walls, areas beneath trees and elevations that receive less direct sunlight can often show contamination first.
Common problems we treat include:
- Green algae
- Black staining
- Red algae
- Mould
- Lichen
- Atmospheric pollution
- General dirt and weathering
- Unsightly patching and discolouration
Rather than simply blasting the surface with high pressure, our soft washing treatment targets the biological growth responsible for much of the staining.
Why Soft Wash K Rend?
K Rend is a specialist render system, so choosing the right cleaning method is important.
High-pressure cleaning can be unnecessarily aggressive on modern rendered surfaces. It can potentially damage the finish, drive water into vulnerable areas and leave the surface looking uneven.
At Mr Softwash®, we use low-pressure soft washing.
The treatment is applied carefully to the render, allowing specialist cleaning solutions to work on algae, mould and other organic contamination before the surface is gently rinsed.
This provides a controlled approach to cleaning while helping to protect the appearance and integrity of your K Rend.
Our K Rend Cleaning Process
Every Broadstone property is different, which is why we assess the render before deciding on the appropriate cleaning method.
1. Inspecting Your K Rend
We begin by examining the render for algae, mould, lichen, staining, cracks, previous repairs and areas of potential damage.
This allows us to identify the type and severity of contamination.
2. Assessing the Surface
The condition and characteristics of the render are considered before treatment.
Where appropriate, we can carry out checks to help determine how the surface will respond to moisture and cleaning.
3. Applying the Soft Wash
A specialist soft wash treatment is applied using low-pressure equipment.
There is no aggressive blasting of the render. Instead, the treatment is allowed to work on the organic contamination.
4. Controlled Dwell Time
The solution is given sufficient time to work.
The required dwell time depends on the level of contamination, weather conditions and the condition of the render.
5. Gentle Rinse
Once the treatment has worked, the surface is carefully rinsed using controlled pressure.
This removes loosened contamination and reveals a cleaner, brighter and more consistent finish.
6. Protection
Where appropriate, additional biocidal or protective treatments can be considered to help reduce future organic growth and maintain the appearance of your K Rend.
Can Green K Rend Be Cleaned?
Yes. Green staining is one of the most common problems we see on modern render.
The green appearance is typically associated with algae and other biological growth. Simply removing the visible staining does not necessarily address the underlying contamination.
Our soft washing approach is designed to treat organic growth rather than simply remove the surface marks.
This can make a significant difference to the appearance of a property, particularly where K Rend has become heavily green or blackened.
Restore Your K Rend Instead of Replacing It
When K Rend becomes heavily stained, some homeowners assume that the render needs repainting or replacing.
In many cases, professional cleaning may be all that's required to dramatically improve its appearance.
A thorough K Rend clean can remove years of accumulated organic growth and weather staining, helping your property look brighter and better maintained without the expense and disruption of replacing the render.

Don't Pressure Wash Your K Rend
If your render is looking dirty, it can be tempting to hire a pressure washer and tackle the problem yourself.
However, K Rend requires a more considered approach.
The textured finish can be vulnerable to aggressive cleaning, particularly if excessive pressure is used or the operator is unfamiliar with modern render.
Soft washing provides a controlled alternative, using cleaning chemistry and low pressure rather than relying on force.
If you're unsure how to clean your K Rend, it's better to have the surface assessed by a professional before attempting DIY cleaning.

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!
