The black stains on render are a common problem for many homeowners. There are several possible causes for these stains, ranging from simple dirt and grime to more serious issues like mildew or mold. Fortunately, there are a number of ways to remove black stains from render, depending on the cause.
There are several types of microorganisms that can destroy render on buildings, including algae, bacteria, and fungi.

It is important to keep buildings well-maintained and free of microorganisms in order to protect the render surface.
How to remove black stains from render?
The black stains on render are typically caused by algae or fungus. Algae and fungus can grow on the render if it is exposed to moisture for an extended period of time. The black stains can be difficult to remove, but there are a few things you can do to get rid of them.
Softwashing is an effective way to clean render surfaces, using a low-pressure wash and specialist cleaning solutions. This method is ideal for delicate render surfaces, as it won’t damage the material.
Another way to remove the black stains from render is to use a pressure washer. Pressure washing can be effective at removing the stains, but it can also damage the render if it is not done carefully.
If you decide to pressure wash your render, be sure to use a low-pressure setting and hold the nozzle a few inches away from the surface. It is always recommended to consult a professional render cleaning company as they have experience and equipment to clean the surface swiftly without any damage.
One more way to remove black stains from render is to use a bleach solution. You can make a bleach solution by mixing one part bleach with ten parts water. Once you have made the solution, apply it to the stained area and let it sit for a few minutes before scrubbing with a brush. Be sure to rinse the area well after scrubbing to remove any residual bleach.
If the black stains on your render are not too severe, you may be able to remove them with a simple household cleaner. Try using a baking soda and water solution. Apply the cleaner to the stained area and scrub with a brush. Rinse well after scrubbing to remove any residue.
No matter what method you choose, be sure to test it on a small area first to make sure it does not damage the render. If the black stains are severe, you may need to hire a professional to remove them.
