Expert K-Rend render cleaning services
Modern through-color renders like K-rend and Weber monocouche are frequently chosen for their low-maintenance qualities in both residential and commercial buildings. However, despite their durability, they still need occasional cleaning to eliminate the accumulation of moss, algae, and everyday pollution, which can gradually wear down the building's appearance and integrity.
Gentle and Effective Softwashing for Render
Pressure washing might seem like a solution, but it's not the most effective method when it comes to render cleaning. Pressure washing can force water deep into the render surface, joints, and small cracks, potentially damaging the K-render surface in the process. Moreover, this approach doesn't address the root issue - it doesn't eliminate the algae spores. They tend to return, causing the same problem to reappear just a few months down the line.
At Coljack, we take a different and more informed approach. We avoid pressure washing render because it's a practice often employed by inexperienced workers who might not fully understand the risks involved. High-pressure washing can not only harm the render but also potentially damage the wall beneath it. We use a gentle yet highly effective softwashing technique that gets the job done without causing any damage.
Effective Low-Pressure Render Cleaning
We specialise in render cleaning using a gentle, low-pressure soft washing technique. This method involves the use of carefully selected chemicals to clean the render effectively. Not only does it remove dirt and grime, but it also eradicates algae and spores without posing any risk of damage to the render surface. Our approach ensures that your render is thoroughly cleaned and maintains its integrity.
