Free information regarding Cleaning Red Streaks on Rendered Walls.
Render is a standard exterior for buildings. It’s a practical method of sealing a structure’s surface against the elements while also changing its aesthetic appearance. Instead of paint, render involves applying a mixture of wet cement and sand “type material” to the outer walls.
While this is a great way to fortify your home’s exterior against severe weather and water damage, some common problems can arise. In this article, we discuss Cleaning red streaks on rendered walls.
One of these is the appearance of red stains, marks, or streaks on rendered walls. These streaks can be unsightly and drive down your property’s value.
What Causes Cleaning Red Streaks on Rendered Walls?
Mistaking red stains on rendered walls for something else, such as rust or silicone runoff, is easy. However, these streaks are manifestations of algae growing on the outside of the walls.
Humid environments or rainwater trickling down the sides of your home provide sources for algae with the moisture it needs to flourish.
Certain types of algae can be hazardous. However, the algae typically found on render are not harmful to humans.
They won’t cause excessive damage to your home, either. That said, the stains are not pleasant to look at. And they can become an obstacle if you want to sell your home.

Top TIPS on Cleaning Red Streaks on Rendered Walls
Algae infestation on outdoor render walls is a problem that can be difficult and time-consuming to deal with.
Algae growth is caused by moisture and humidity. Meaning it’s not something that can’t be ignored.
If left untreated, the algae can cause permanent staining to the render surface, making it necessary to take action as soon as possible.
Luckily, there is a straightforward solution to the problem of algae on rendered walls.
You’ll need a specialist biocide to kill and remove the algae. This is applied at relatively low pressure not to damage the render.
The active ingredient we are looking for in any Biocide brand is DDAC. This is the “go to” product for cleaning red streaks on rendered walls.
Read the label for the list of active ingredients. DDAC, also known as Didecyl dimethyl ammonium chloride, is an active ingredient in BIOCIDE, a disinfectant.

What our Customers say
It is widely used in the cleaning and hygiene industries due to its efficiency and effectiveness against bacteria, moulds and fungi.
In fact, DDAC has been proven to be a powerful antimicrobial agent with the ability to kill microorganisms within minutes. Furthermore, DDAC is environmentally safe and non-toxic when used properly.
We recommend consulting a professional if you have concerns about damaging the exterior. You want to apply only a little pressure, and selecting the right biocides for the specific algae strain can be a tricky task best left to the pros.
What About Painting Over the Stains?
Painting over the red streaks might be a temporary solution, but it won’t keep the algae from returning.
It will continue to grow under the paint, and the red marks will eventually return to the outside of the rendered walls.
At this point, it will be more challenging to clean off because a layer of paint will be in the way.
