GK PRO has quickly become the cleaning and maintenance sector's favourite chemical for eradicating biological growth. 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 method of treating moulds, algae, lichens, and most other biofilms. It is a natural surfactant cleaner, so will foam vigorously when applied by brush or spray, this a great indicator to ensure all areas are treated.
It can be used on almost ANY hard substrate (excepting green or sedum roofs) and is especially good for historic and fragile substrates including thatch.
GK Pro is applied at low pressure reducing the likelihood of damage that harsh scouring, scrubbing or water blasting can do.
GK Pro does not contain any harsh chemicals that many bleach-based cleaners incorporate. If used as instructed it will not oxidise or negatively impact on hard surfaces, or other component for example lead works, UPVC windows and seals.
GK Pro acts only on living cells and is an effective sanitiser for 99·9% of bacterial matter.
For smaller areas no specialist equipment is required - a garden sprayer will do. Whilst applying appropriate PPE should be worn, we recommend protective gloves and eye protection/face protection as a minimum requirement.
The active ingredient (DDAC) offers residual activity and helps prevent premature recontamination.
