Render is used across the UK, especially on large modern buildings, but the manufacturers of render recommend that it needs sprucing up from time to time. If not cleaned regularly to the colour of render will appear to fade. This is because render is likely to become infected with algae, mosses, and lichens that stain and ruin the apperance of a home or commercial building. Ionic Window Cleaners is a safe and eco friendly way of removing organic matter and atmospheric pollution from exterior render. Finished coloured renders like K-Rend, Moncouche and Weber suffer with algae, bacteria and mildew staining. Weather and pollution can also lead to staining and discoluration. At Ionic Window Cleaners we use our low pressure unit to gently clean render surfaces. If render is subjected to a high pressure wash it can cause long term damage, while Ionic Window Cleaners will not harm the buildings substrate. A Softwash will will return any render surface cleaned to its natural state, looking freshly painted, thus increasing the buildings kerb appeal and value. We restore these surfaces to as new condition safely from the ground in most cases. In fact we can restore any rendered surface including painted render and all pebble & spa dashed finishes.

It is also very likely that your render will look worse on the north and east sides of the building, where there is less natural sunshine. Having studied the science behind building maintenance, we know that most common atmospheric infections leave swathes of render surfaces with widespread green staining. This can be particularly prevalent on buildings in close proximity to water, as humidity feeds building infections, and the cross contamination caused by spores from nearby trees or other large foliage is a helping factor in this. Left untreated, these stains look tremendously unsightly, and they can detract from the appearance of a home or business. The warmer, more humid weather in the UK means that atmospheric growths are thriving, and are growing on render finished facades harder and faster than ever. Trying to remove these organic growths can prove problematic. High pressure washing can cause real damage, and if incorrectly removed the infection will return too soon. With our softwash treatments we apply softwash detergent blends, with steam, to both clean the building and eliminate the infection. This ensures the building looks great after cleaning, and keeps its brilliance.

The staining and discolouration of render leads many to think that full re-painting is the solution. This is expensive and completely unnecessary. When it is clean, render keeps its colour! Cleaning render is the recommended and more cost effective way to maintain K-Rend surfaces. Until recently however, high pressure cleaning was the only option available. Whether using hot or cold water under high pressure, the aggressive technology blasts moisture beneath render’s surface, which means organic growths return shortly after cleaning. In many cases, high pressure cleaning has even blasted render totally off the wall!
