Algmedel JAPE Grön-Fri koncentrat
• Against growth of algae and lichen
• For all surfaces and materials outdoors
• Growth disappears over time on weather-exposed surfaces
• Prevents new growth
Areas of use On all types of surfaces, i.a. roofs, facades, ground surfaces, fences, wooden trellises, stairs, walls and awnings. Grön-Fri can be used on both painted and untreated materials such as wood, plaster, stone, brick, concrete, eternit, tin, roofing felt, plastic, textiles, etc.
Properties When treated with Grön-Fri dies growth immediately. On weather-exposed surfaces such as roofs, the rain washes away the residues over time without the surface needing to be processed afterwards. Algae are normally gone within a year and lichen after about two years. On painted vertical surfaces, e.g. facades, in most cases the surface needs to be washed in order for the residues to completely disappear. Let Grön-Fri work for at least 24 hours if the surfaces are to be washed. Grön-Fri has a preventive effect because nutrients on the surface are neutralized. Establishment of new growth can only take place when new nutrients have stuck to the surface. On e.g. roof, it generally takes up to 4 years before new growth is visible again, on exposed shady surfaces it may return sooner. Grön-Fri is slightly corrosive and can therefore affect untreated metals, for example aluminium, zinc, copper and stainless steel, but otherwise does not adversely affect any building materials. Biodegradable.
Instructions for use Dilute Grön-Fri with water. Apply with a low-pressure sprayer with a spreading directed flat jet, for example the Fri-Sprutan, so that the surface becomes wet. Grön-Fri can also be applied with a brush. Avoid treatment on frost-covered surfaces or if a large amount of rain is expected on the surface within 12 hours. Flowers and plants nearby should be covered as they can be damaged. When treating the roof, moss must be removed in advance. When spraying, respiratory protection is recommended as the spray mist can be irritating. Protective gloves and goggles should be used.
Dilution 1 part Grön-Fri is diluted with 4 parts water.
Consumption 0.20-0.25 liters of application solution/m² . 1 liter Grön-Fri diluted to 5 liters of use solution is enough for approx. 25 m² (1 liter of use solution is enough for 5-6 m²). For problems with black dots on painted surfaces, Prick-Fri is recommended.
Precautions for use Use Grön-Fri safely. Always read the label and product information before use. Read more about the problem areas and work advice available for the product.
