Benefits of Soft washing K Render

K Render Cleaning Services should be undertaken by a Certified Softwashing Pro!

Choosing an experienced K Rend Soft washing specialist will ensure high quality results that are long lasting.

Soft washing UK experts Purple Rhino, will prevent exterior render damage occurring to your properties K Rendered Surfaces whilst being cleaned, no high pressure is used.

When you want the highest quality care for your building, SoftWashing will give you the very best cleaning results – Guaranteed!

The great British weather over recent years has been extremely warm and wet during winter months, algae; moss and other organic matter have been thriving on K Rendered Surfaces which can cause serious damage to the render if left uncleaned. Softwashing is often the best answer to ensure a cost effective render cleaning solution for you. In some cases we can clean high level render safely from the ground using our Render Cleaning Machine to precision spray the affected K Render surfaces.

Soft Washing in the UK is a fairly new type of exterior building cleaning service, specialist SoftWashing equipment must be used to ensure the soft washing mixture has been blended properly prior to use. A typical softwash machine can be seen here

Modern buildings always look impressive but often over time K- rendering becomes dirty with pollutants, moss and algae taking over, leaving the building looking tired and stained. Purple Rhino Soft washing teams specialise in safe and effective render cleaning solutions for each individual building using the latest methods and techniques which gently remove all colours of organic matter build up without causing any damage to the K Render underneath.

From the very beginning Purple Rhino have established long lasting partnerships with facilities managers and housing associations that know and understand our methods for best removal of all types of staining to K Rendered surfaces on all types of commercial, educational and residential properties. The benefits of correct render cleaning should not be underestimated. Purple Rhino would never use a high powered pressure washer to clean K Render as this will cause damage and further problems.

Here’s how we Softwash K Render Surfaces

These days it’s quite easy using a SoftWash System which has a Blend 50 module, which safely mixes up the SoftWashing Solution which is then sprayed onto the K rend surface leaving it sanitised clean and new looking. The treatment lasts longer than pressure washing would.

Other cleaning methods also using an environmentally SoftWashing Solution is extremely important. A mixture is made up in the Render Cleaning Machine and is sprayed accurately and evenly to the dirty K Rendered surfaces. Organic matter which has been allowed to grow into the K render surface is then steam cleaned off using a Doff Machine which is the only machine of its type which has been approved for use by English Heritage.

It depends on the depth of the stains on the K Rendered surface and is there any organic growth or just different coloured hues across the rendered façade as to exactly which cleaning process will be required, more often than not Purple Rhino use all types of equipment on any one buildings rendered facades.

SoftWashing lasts 4-6 times longer than pressure washing

We always use a specially formulated biocide which we have made up for us with a surfactant and scent built into it.

Often after spraying the whole rendered facade we then proceed to DOFF steam clean the heavy organic growth areas at up to 150 degrees C at VERY LOW pressure – typically 50 BAR with only 5 ltrs of water per min – in our opinion this is the only way to complete the task successfully.

X –Jet is another tool employed by the Softwashing contractor. Basically combined with a low pressure jet washer a biocide can be sprayed over 15 metres high to completely and safely cover the organic stained K Render without the need to bring in costly access equipment. Not the best solution for softwashing type of work but better than pressure washing.

Often building managers contact pressure washing companies to remove mosses and algae’s from K Rendered surfaces mainly because they have never heard about Softwashing services. Using the wrong method to clean K Render often results in a very costly mistake to the building owners.

K Render cleaning without the necessary equipment and correct training can cause serious and damage to the K Rend. Rendered surfaces need to be first treated with an appropriate biocide, which effectively kills off organic spores to prevent them re-growing on the K Rend surfaces. Steam under low pressure and up to 150 degrees C is applied to gently remove any growth which remains after the initial treatment as well as removing any atmospheric pollutants and other types of grime. Properly cleaned K Render will ensure your building looks its very best.

What our Clients Think

See all testimonials
  • From my initial contact with Purple Rhino to the finish, their work was very professionally carried out. Their team arrived on the arranged date and completed the work to a very high standard. Also, at very short notice, they managed to carry out a large cleaning schedule over a weekend in order for the school to look it’s best for a visit by RIBA judges. This was safely completed while various areas were in use. Definitely a five star service and I would recommend this company.
