A cleaner for walls and external hard surfaces which removes moss and algae. Based on organic acids, is safe to use and cleans without the risk of damage to surfaces. Suitable for use on:
Apply when rain is not imminent. Do not use in very cold conditions or where surface is unlikely to dry after application. Dilute with up to 5 parts water and apply using brush or spray so that surface is thoroughly wetted.
Coverage is approx. 25 sq. m per litre of concentrate, depending on the absorbency of the surface. Allow the surface to dry without washing off the cleaner solution. For lightly contaminated surfaces no further treatment may be necessary and the cleaning and brightening effects will be seen within a day or two. In more severe cases, dried out residue should be brushed away from the surface or removed with a power hose. Where there is thick moss growth a further application may be required.
