Cleaning solutions for roofs and external surfaces

Mossgo pro removes all moss, algae and lichen problems. Mossgo pro is a biocide. It kills micro-organisms which colonise external surfaces. This includes viruses, bacteria and algae. When the algae within the lichen and moss die, the whole organism dies and disappears without reproducing. Cleaning tiles using Mossgo pro is the most durable solution.

How long does Mossgo pro take to act?

Mossgo pro is a "soft" and gentle treatment designed to remove growth safely without causing damage to external surfaces. It starts to act immediately and usually begins to produce results within 24 hours. But some organisms will take a little more time to wither away. Although it takes longer than mechanical roof cleaning, methods such as power jetting or scraping, it produces better results and with no damage to roof surfaces.

Moss usually begins to wither within 24 hours. Moss balls will usually start falling down within a few days depending on the exposure to wind and rain.

Algae dies almost immediately. If the layer is thick, a white discolouration takes place within a day or so. Dead algae is rapidly dispersed. Red algae can be cleaned from rendered external surfaces often found in coastal environments.

Lichen are well-encrusted and take a little longer to fall away. Dead lichen become soggy with rain, and curl when dry. After many cycles they finally drop. Cleaning lichen without damaging the substrate is a patient undertaking. Dark background discolouration on concrete tiles washes away over a period of several weeks.

Environmental footprint

Mossgo pro is a fast degrading product. Just 48 hours after application, about 85% of the active has already broken down. There is no durable environmental footprint. Short lived as it is, Mossgo pro is nevertheless a powerful algaecide and concentrate and should not be allowed to spill into watercourses. If spray drift is likely to be a problem, then cleaning tiles on windy days should be avoided.
