Why is my render turning Red?
In the UK, where weather conditions can be unpredictable, exterior surfaces are constantly exposed to moisture, pollutants, and biological growth. Amidst this, if your render turns red, it can be both an aesthetic concern and a sign of deeper issues.
Why is my render turning Red? Understanding the Dynamics of Trentepohlia Algae Growth on K Rend Render
The Algae Menace:
Trentepohlia algae, a green organism with a penchant for donning a red or orange hue, is a photoautotrophic plant that utilises sunlight to produce food. While it may sound harmless in its natural habitat, on the exterior of rendered walls, Trentepohlia becomes an unwelcome intruder, causing the distinctive red streaks that can transform a pristine render into a visual nuisance.
Environmental Factors:
Understanding the conditions that foster Trentepohlia growth is pivotal to addressing the issue effectively. High humidity levels provide the ideal moisture content for algae development.
If your region experiences frequent rain or has a generally humid climate, it creates an environment where Trentepohlia can thrive. Moreover, areas with limited sunlight, such as those shaded by trees or tall structures, are susceptible to algae colonisation.

The Role of Porosity:
The porosity of the K Render substrate also plays a crucial role in algae infestation. Rendered walls with higher porosity possess more microscopic spaces for moisture retention, inadvertently creating a conducive environment for algae growth.
As Trentepohlia establishes itself in these tiny crevices, it forms red streaks that can be challenging to remove without proper intervention.
Preventive Measures:
- Regular Cleaning: Establishing a routine cleaning regimen is the first defence against Trentepohlia. Use a mild detergent or specialised algae-cleaning solution and a soft brush or pressure washer to remove algae spores from the render gently. Regular cleaning disrupts the algae’s life cycle and helps prevent its establishment. DDAC is the most commonly used biocide.

- Enhancing Sun Exposure: Trim trees and foliage that cast shadows on your rendered walls. Increasing sunlight inhibits Trentepohlia growth, as the algae relies on shaded areas to thrive.
Allowing more sunlight to reach the rendered surface creates an inhospitable environment for algae colonisation.
- Algae-Resistant Coatings: An algae-resistant coating is a proactive measure to safeguard your K Render.
These coatings are designed to create a protective barrier, deterring algae growth and making it easier to clean the surface when necessary.
- Moisture Management: Addressing sources of excess moisture is paramount.
Check for leaks, fix drainage issues, and ensure proper ventilation around your property.
Managing moisture effectively reduces the humidity levels, contributing to Trentepohlia growth.
