The problem – K-Rend Disaster
I received a phone call from a frantic customer. They had hung a Halloween decoration from an upstairs window, which after a bout of rain, had leached dye into the porous K-Rend, resulting in a K-Rend disaster. The property had only been rendered with K-Rend the month before at a considerable cost. They had tried fairy liquid and pressure washing the area to no avail. Their last option before an insurance claim was to contact a company experienced in cleaning K-Rend render. Admittedly, this is the first time I’ve encountered this particular problem, but I was confident we could help.
What is K-Rend
K-Rend is a wall insulation and rendering system used to improve the appearance and energy efficiency to the outside of buildings. It is made from a mix of cement, lime, and various aggregates and is applied to the surface of the external walls. K-Rend is used on many wall types, including brick, concrete, and stone. Available in a range of finishes, K-Rend requires only occasional cleaning to keep it looking its best. In addition to its practical benefits, K-Rend is made from natural materials and contains no harmful chemicals.
What we did
We began by gently steam cleaning the area around and including the stain. We wanted to saturate the render and remove as much stain as possible before we resorted to chemicals. Once we were confident as much contamination as possible had been removed by the steam cleaning, we applied our in-house proprietary blend of detergents and cleaning agents to gently draw the dye from the porous render. As the K-Rend render is so soft and easily damaged, we had to reapply our chemical mix several times, gently agitating the surface of the render each time.
The results
As you can see from the pictures, we were 100% successful in removing the dye stains from the newly rendered wall in Cheadle, Greater Manchester, much to the relief of the homeowners. Contact us today if you have K-Rend that needs some TLC. We can clean just about any stain from your K-Rend including but not limited to rust, algae, mold, lichen, fungus and just general soiling and pollutants.
