  1. The Culprit: Algae and Moss

    – The green discolouration on your render is most likely the result of algae and moss growth. These microorganisms thrive in damp and shaded areas, making exterior walls an ideal breeding ground. The moist environment creates a perfect habitat for these unwelcome guests to flourish, leading to the greenish appearance on your render.

  2. Harmful Effects of Algae and Moss

    – While green render might seem like a cosmetic issue, it can have more significant consequences. Algae and moss can penetrate the surface, causing damage to the render and even leading to cracks. Additionally, they can absorb and retain moisture, which may weaken the structure over time. It’s crucial to address this problem promptly to avoid costly repairs down the line.
