I have exterior walls that are rendered with a silicon render (K-Rend). The walls are exposed to the prevailing wind and rain and when these are strong they wash off a small amount of material. Over time this small amount will add up! I want to 'stabilise' the render but do not want to stop the silicon from working correctly and being waterproof and breathable. Suggestions please. Jonathan
It sounds like this miracle wall finish is not living up to its promise. Being 'waterproof' and 'breathable' is not something you're going to achieve. Since this miracle wall finish is likely still under warranty, the best people to ask are Keim themselves.
