Rendered buildings are nothing new; simple renders have been used to protect and decorate buildings for several thousand years. However, modern renders are significantly better in terms of water resistance and insulation, protecting your home for decades.
One brand in particular that Right Wash has become familiar with is called K Rend, and it is now used extensively as an exterior render for commercial buildings as well as homes.
K Rend is an extremely popular option these days, as it is a through-coloured render, meaning that the pigment is added during the manufacturing process. Because of this, the colour won't fade and will last for around 30 years or more.
This highly durable low-maintenance render uses limestone and silicone to provide a superior mix that allows your walls to breathe and expel excess moisture, which prevents damp and mould problems. At the same time, it protects the external surfaces from the weather and is available in a wide variety of colours and texture finishes.
Even so, you need to clean K Rend surfaces to keep them looking their best. Commercial and residential properties look unsightly and neglected when the render becomes dirty and stained. What's more, this can cause problems if it's left for too long without being cleaned. This is why K render cleaning and render cleaning is such an in demand service.
Rendered buildings have many enemies in the form of atmospheric pollution and organic growth. Green algae, moss, mould and bacteria attack the render surface and will eventually cause damage. Pollution causes stains that can be difficult to remove, resulting in the need for re-rendering.
It's possible for render to have red (how to remove red algae), black or green stains that spoil the appearance of your property and reduce the lifespan of this protective coating. It makes sense economically to clean render periodically rather than risk waiting a few years, by which time you might need to have the surface repaired or even re-rendered.
At Right Wash, we have extensive knowledge of all types of render, including K Rend. We will use our expertise to keep your rendered walls looking their very best and ensure that they protect your building for years to come.
Although it sounds like a simple job, few people are prepared for what's involved and the results aren't always as good as they expected or desired.
You need to be very careful as to what you use when cleaning render. Harsh chemicals and bleaches can damage the render surface and can harm wildlife if they are washed into the ground.
Many people assume that a pressure washer is the answer, but, once again, care is needed; some renders are prone to damage if a high-pressure setting is used, especially if the nozzle is set to a narrow jet instead of a wide spray. Water is forced deep into the render surface and will expand as it freezes in winter, causing it to crack. You will then be left with the extra expense of having to repair the damage.
Also, it's likely that you'll need to work up a ladder to reach the upper levels, which is potentially hazardous.
Right Wash k render cleaning services can take away all of this hassle. Our expert K Rend cleaning specialists are familiar with all render types and the best methods of cleaning them. They are also trained and certified in the use of relevant tools and equipment, including those for working at height.
Finally, your K Rend warranty may be invalidated if you use an unqualified or inexperienced company or damage the render doing the job yourself.
Each job varies according to size and scale, and the type of property. However, Right Wash approaches each project with the same level of efficiency and professionalism, no matter the size.
The process begins with an inspection to establish the state of your render and the scale of the job. We can then offer a more precise costing for the project, and it helps us to identify any potential hazards or problems with access.
It may be possible to estimate a figure using photographs, but any work on a commercial building will involve a full site survey.
Right Wash specialists will select the appropriate cleaning method (in this case, for K Rend) and prepare the site.
In most cases, they will use the soft washing technique or DOFF cleaning system. This is an effective method that uses a washer on a low-pressure setting with a biodegradable render cleaning solution. The nozzle is adjusted to a fan setting and the first spray loosens the dirt.
Fungicides and biocides may be added if there is algae growth or any other organic matter present. Not only does this help to remove algae but it will also prevent it from returning in future as it deep cleans the surface to kill microscopic spores.
The team will remove stains efficiently, targeting areas of stubborn staining to achieve outstanding results.
The final stage involves washing the surface areas down with clean water, after which the team will clear away all of the equipment and tidy the working area.
Your rendered building now looks just as it did when the coating was first applied!
Although we've covered the basics, there may be some points that you're uncertain about, so here are a few to consider:
All of our cleaning solutions are used at safe levels for humans, pets, wildlife and plants. Right Wash staff are trained in the proper use of these chemicals to minimise the risk of harm.
It depends entirely on the size of the project and whether special equipment is needed for working at height. There's also the question of how bad the staining is; graffiti can be particularly stubborn, and if algae growth has been left untreated for years it can require extra attention.
As a ball-park figure, a medium-sized three-bedroom house costs around £500. Bear in mind that this is a rough estimate. To get a better idea, call us today for a free quote with no obligation.
On average, each job takes between one and two days. Obviously, larger properties and commercial buildings will generally take longer.
Although our staff appreciate the need to cause as little disruption as possible, they will never rush the job simply to get it done. Efficiency is key, but it's the quality of the finish that counts.
Most projects will require the use of equipment for working safely at height, and this is a point that we will not compromise on under any circumstances: the safety of our staff and anyone on site is paramount. We will erect scaffolding or use a MEWP (Mobile Elevated Working Platform) whenever necessary.
For example, modern townhouse-style homes tend to be taller, requiring more effort to reach the higher floors, and this will be reflected in the time taken and the total cost.
Not necessarily, but we do need access to water and an electricity supply. If these are not readily accessible outside of your property then we will need permission to enter your home if you are not present.
Definitely! Right Wash has found this method to be extremely effective on exterior render, leaving the surfaces clean and free from algae and mould for up to five years.
Most clients who previously used the pressure washing method usually request soft washing these days.
Ideally, a thorough wash once a year will do the trick.
As mentioned above, a soft wash can last for around five years. However, much depends on your location, pollution levels, and local weather patterns.

Jet washing is the best way to clean various types of k render according to various manufacturers of the actual render. Power washing will remove a lot of dirt and algae but algae and moss can penetrate into the porous render types making steam cleaning and soft washing a slightly better option in some cases.
Three to five years is a common figure for k render staying clean after a good wash but things like blocked gutters & plants being too close to the walls can make dirt and algae appear much faster on any type of k render.
Yes, steam cleaning k render and soft washing is one of the best ways to clean render as there is less risk of damage to the k render that you would likely get from jet washing.
To refresh a k rendered wall that is covered in dirt, algae, moss or lichen then the safest way for all k renders is soft washing and low pressure steam cleaning. In some modern k renders you will be able to just jet wash it.
