Why GK Pro?
At Cleaning Service Exterior Cleaning, all products we use are eco-friendly and biodegradable. We test and study the science behind every product. Besides visible evidence of its efficacy we’re particularly concerned that products introduced to remove algae and mould growth, will not cause long term damage to any components like sealants, adhesives or fixings used in the render system. We recently tried GK Pro, a high purity DDAC biocide, my team found it easy and adaptable in use. On heavy soiling we brushed-in, the dense foam drew all the grime well, rinsed and a light re-spray. As a spray and leave formula on regular staining the results were excellent; I have no problem in recommending GK Pro.
