K Rend cleaning
K Rend surfaces can be cleaned safely using
soft washing, a low-pressure method that uses specialised chemical detergents to dissolve organic growth like algae and mould without damaging the render. While the manufacturer, Kilwaughter Minerals, states a pressure washer can be used on a low-power "fan" setting with mild detergent, many professionals advise against it to avoid risk of cracking or water penetration.
Recommended Cleaning Methods
- Soft Washing: This is the most widely recommended professional method for K Rend. It involves applying a biocide or sodium hypochlorite mix at low pressure, allowing it to "dwell" to kill algae at the root, and then rinsing gently.
- Biocide Treatment: For organic growth like green or red algae, applying a specialized wash such as softwash biocide is effective. It kills the infection and continues to work as it naturally weathers off over several days.
Maintenance Tips & Precautions
- Avoid High Pressure: Never use high-pressure jet washing, as it can strip the render surface, cause "blown" sections, or force moisture into the render.
- Frequency: Most K Rend surfaces benefit from a professional clean every 2 to 3 years, though shaded or coastal properties may need it every 12 to 18 months.
- Protective Coating: Cleaning with softwash biocide will clean and protect against further contamination of algae regrowth for 3-5 years.

Benefits of Soft Washing
The modern, technologically advanced, process of soft washing reduces, and even eliminates, the need for jet – or pressure/power – washing in most situations.
Soft washing is the process of using eco-friendly chemicals and low-pressure water to clean the surfaces of buildings and driveways.
Soft washing will not damage your property. It's effectiveness depends upon the cleaning contractor having the skilled knowledge of how to use the correct cleaning product at the correct concentration ratio, using the correct equipment.
Soft washing provides long-term exterior cleaning by using low pressure and specialized chemicals (like sodium hypochlorite) to kill mold, algae, and moss, preventing regrowth for years (often 3-5) and keeping surfaces cleaner longer than pressure washing. It's a safer, deeper clean for delicate surfaces (roofs, render, wood) because the biocides sanitize, sanitizing the source of the organic growth and offering a residual effect against future build-up. Annual or biannual treatments maintain results effectively and cost-effectively.
Softwash Long Term Protection for 3-5 Years
Soft washing with biocides provide long-term protection by
killing organic organisms—such as algae, moss, fungi, and lichen—at their root and leaving a residual film that prevents regrowth.
How Biocide Protection Works
- Residual Action: Unlike bleach (sodium hypochlorite), which provides an instant clean but no lasting protection, biocides like DDAC (Didecyldimethylammonium chloride)penetrate porous surfaces. They continue to kill spores that land on the surface for months or even years after application.
- Self-Cleansing Process: Many professional biocides are "spray and leave" products. They work with natural weathering (rain and wind) to break down and wash away dead organic matter over several weeks or months.
Is Soft washing with biocide
the best method for cleaning render?
Yes, bleach can damage render if used incorrectly, primarily through discolouration and surface degradation. While sodium hypochlorite (the active ingredient in bleach) is a standard professional tool for "soft washing," bleach is often too strong or if used at improper dilutions for delicate surfaces like Krend and Monocouche renders.
How Bleach Can Damage Render
- Permanent Discolouration: Using bleach straight from the bottle or in high concentrations can cause patchy, white, or streaked finishes due to a pH imbalance.
- Surface Etching: As a corrosive alkaline solution, concentrated bleach can break down the surface chemistry, stripping away the water-repellent silicone layer that protects modern renders.
- Salt Residue: If not thoroughly rinsed, bleach leaves behind salt deposits (efflorescence). These salts attract moisture, which can actually encourage faster regrowth of algae and moss.
- Warranties: Using unapproved chemicals or high concentrations can void manufacturer warranties for products like K Rend or Monocouche.
Steam cleaning render
Steam cleaning ( Doff/Torc ) render is highly effective for removing heavy carbon staining or paint, but lacks the long term residual protection against algae that biocides provide.
soft washing with a biocide is widely considered the best and safest method for cleaning modern exterior renders like K-Rend and Monocouche.
High pressure jet washing
- Is a way to get immediate results that look good – but only for a short time.
- Can be damaging to the protective surface layer of the material being cleaned, even concrete.
- Can be damaging to wall render, because render is a relatively soft material.
- Can be damaging to certain more delicate building materials often used for patios and paths, such as Indian Sandstone.
Soft washing
- Is the best solution for cleaning exterior wall render, natural and artificial slate roofs, concrete slate roofs, paths & patios, tarmac driveways, wood decking, sheds and fences, and children's wet-pour play areas.
- Is a cleaning method that produces fast, predictable results without harming your property. Results that can last for years.
- Is a cost-effective way to bring drives, paths and patios back to their former glory. Once clean, a light annual soft wash treatment will keep your drives and paths looking great all year round.
Soft washing has many other advantages over jet washing
- Longer lasting results
- Uses less water
- Is more cost-effective
- Is safe for all known building materials
- Does not damage the surface being cleaned or exaggerate the weathering affect
- Kills the spores left behind by jet washing
For long-term maintenance of the exterior surfaces of your property – ensuring it looks great all year round – annual or biannual treatment with a Mr Softwash product is by far the safest and most cost-effective option.
What is Soft Washing?
The Safer Way To Wash Your Home.
Soft Washing was developed in the USA about 20 years ago and was a way of washing property without the risks associated with using high pressure as in pressure washing. Soft washing is a cleaning process that safely removes organic stains, mildew, and algae from render using a low-pressure washing technique and a mixture of biocides or sodium hypochlorite, surfactants, and water. High pressure damages render, roofs and other surfaces, so Low pressure is used to prevent any damage.
Soft washing or low pressure is used on surfaces that are difficult to clean with pressure washing or might be damaged by high pressure. It's gentle on surfaces, making it ideal for delicate materials.
Soft washing is different from power washing, which uses higher water pressure. Power washing can void a warranty, cause granule loss, and compromise the integrity of roof tiles, damage rendering, patios and other surfaces.
What is the distinction between Soft Washing and Pressure Washing?
Although the procedures, equipment, pressure, and chemicals used in soft washing, power washing, and pressure washing appear to be identical, they are not. Power washing and pressure washing require much higher water pressure than soft washing, and power washing is usually done with high pressure. To kill mould, mildew, bacteria, algae, fungus, moss, and other bacteria, the Soft Washing method is paired with a biodegradable sanitizing cleaning solution.
This biowash will continue to prevent further organic growth for about 3-5 years.

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.

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!!
