Cleaning Render is More Than Just Cosmetic.

Despite this technical advance, even K Rend surfaces will, over time, become coated in algae, moss and dirt making the render look drab and dirty, leaving your commercial property looking less than acceptable. 

But that’s not all…

Algae, whether it is the red, green or black form, if left to grow unchecked will penetrate and discolour the render. Once this has happened, there is no going back. Your K Rend will forever look stained unless it is removed and replaced. 

Left even longer, the Algae and moss can penetrate the fabric of your building, weakening the mortar, the bricks and stonework and allowing damp to penetrate, reducing the value of an expensive asset and necessitating repair. 

Render and K Render Cleaning is A Specialist Job


Choosing the right contractor to clean the K Render of your commercial building is important to the success of your maintenance project. Many businesses like yours have found that getting it wrong costs a whole lot more to put right than calling in an expert in the first place.

Using the wrong equipment and the wrong chemicals can harm and discolour the K Rend coating on the exterior of your building. This will leave your building more susceptible to damage as the weather and contamination, including algae, can penetrate the render. The damage caused by an inexperienced operator could cost you thousands of pounds to put right. 

Using An Accredited Company for Render Cleaning With The Appropriate Products and Equipment is Paramount

During the cleaning process, it is crucial to destroy any of the microscopic spores that lurk in difficult to clean pores in the K Rend. If any are missed, regrowth will occur faster than would otherwise be the case.

APT, along with our consultant chemists have developed Algae Free, a cleaner specifically developed to quickly kill off all traces of algae, moss and their spores from K rend and other renders, slowing down the inevitable re-growth. Algae Free is safe, with non-acidic ingredients, is 100% biodegradable, phosphate free and therefore environmentally friendly.
