This dramatic orange stain on white rendered walls was how we left a job looking. We can confidently walk away from a job like this knowing that we intended to cause this chemical reaction. We sprayed these walls with a high purity biocide to soak in and kill off the biofilm that has developed on this splendid old property. The cost to get scaffold up and paint the walls would be much much more .
The spray treatment not only cleans the substrate but it also soaks in to the surface in order to give a kinder lasting protection against regrowth. WE choose Algo clear Pro because it’s non caustic and non bleaching.
we popped back today( a week later )to see how it was looking . The result were very good !
