Neutralon is a Danish-produced algae remover that has received approval from the Danish Environmental Protection Agency. It is specifically developed for professionals to tackle all types of algae on various hard surfaces, including cement, fibre cement, concrete, brick, wood, glass, metal, plastic, EPDM, PVC and TPO. Notably, Neutralon does not discolour zinc. Neutralon is approved for sale in Denmark, Norway, Sweden and Finland.
No spray certificate is required for algae cleaning on roofs. This product is solely for professional use in algae control on hard surfaces. For surfaces heavily overgrown with algae, mechanical cleaning is advisable prior to application. The surface must be dry before applying Neutralon. The recommended mixing ratio is one part Neutralon to nine parts water, which can be applied using a brush, roller or sprayer. From 1 litre of Neutralon, 10 litres of mixed solution can be obtained, sufficient for 50-60 m² of surface coverage. The ambient temperature during application must be at least 5°C.
