HBS GoRend Monocouche render is a popular choice for new-build properties due to its consistent quality, durability, and vibrant, long-lasting colour.
This factory-produced render is entirely through-coloured, meaning it retains its colour for years without fading. Ideal for finishing multiple properties with the same colour and standard, it doesn’t require a basecoat application, reducing both time and construction costs.
It can be applied by hand or machine to blockwork and is breathable, ensuring healthy, damp-free building interiors. HBS GoRend Monocouche render is also highly weather-resistant and durable.
Even though HBS GoRend Monocouche render is designed to maintain its colour, external factors like organic growth can impact its appearance over time. For example, black mould and algae can colonise the surface, diminishing its look. In this case study, you’ll see how black mould invaded the render, reducing its aesthetic value.
While black mould is often the most noticeable contaminant, it doesn’t appear on its own. Initially, less complex algae, often green or red, establish themselves first. These algae create the ideal environment for black mould to thrive. Once black mould appears, it’s crucial to act promptly—leaving it untreated can not only harm the render’s appearance but also cause long-term damage to the substrate beneath.

Restoring your HBS GoRend Monocouche render to its original condition is simple with the right cleaning method. Algae and light stains can be treated effectively using soft washing, a gentle, non-invasive cleaning method that uses steam and a biocidal solution to remove the contaminants. For more stubborn black stains, specialist cleaning treatments combined with steam are recommended. It’s important to fully rinse the treated areas after using chemical cleaners to remove salts and other compounds that could encourage future re-colonisation.
In our video case study, the HBS GoRend Monocouche render was cleaned and restored from the safety of the ground using extendable poles. Additionally, the slate flooring was also restored to its original condition.
