GK Pro 5L
GK PRO has quickly become the roof cleaning and maintenance sector's favourite chemical for eradicating biological growths on pitched roofs. Simply following the dilution ratios and saturation levels recommended ensures a predictable and successful outcome every time.
GK Pro’s primary function is as a reliable and predictable method of treating moulds, algae, lichens, and moss. Its secondary use is as a natural surfactant cleaner so foams vigorously when applied by brush or spray, always useful as a guide for the operator.
Can be used on ANY roof substrate (excepting green or sedum roofs). Especially good for historic and fragile roof substrates, applied at low tap pressure it’s non-invasive so will not harm the roof, it prevents the likelihood of damage that harsh scouring, scrubbing or water blasting can do (applied between 3 and 6 bar).
GK Pro doesn't contain the solvents or harsh chemicals that many bleach-based cleaners incorporate. If used as instructed it cannot harm any substrate and will not oxidise or negatively impact on any roof component, it will not show any effects on leadwork – it acts only upon living cells and is an effective sanitiser on 99·9% bacterial matter
For smaller areas no specialist equipment is required - a garden sprayer will do. The active ingredient (DDAC) offers residual activity and helps prevent premature recontamination. GK Pro has a shelf life in excess of two years.

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.
