Fassa Bortolo Active One Mould Cleaner is used as a detergent solution for cleaning masonry surfaces showing deterioration due to various types of hard-to-remove stains and dirt, as well as aiding the mechanical removal of mould from walls.
ACTIVE ONE is ready-to-use and is applied by brush or using the spray bottle provided. Apply the product directly onto the surface being treated, leaving it to act for around 30 minutes, then wash with plenty of water. If there is considerable hard-to-remove dirt on the surface, repeat the treatment a number of times, as well as brushing the surface mechanically.
Before starting the treatment on rendered walls, perform a test application on a small area so as to check for possible discolouration or bleaching of pigments that are sensitive to strong oxidants. Please read technical & safety datasheets
Active One covers approx. 6-8 m²/l per coat
Fassa Active One is supplied in 0.5 ltr bottles
