How do I use MO55 Terminator?

Apply MO55 Terminator to dry surfaces only. Dilute 1:4 for normal use or up to 1:9 for light growth in low pressure garden sprayer or watering can. Rinse out applicator after use. Do not apply if rain is expected in next 5-6 hours. For heavy growth, brush off before treatment.

Application dosage is 3.5m² to 7m² per litre. Allow a contact time of 2-4 days. Elements that you want rid of should turn brown when dead. The next step is to brush, scrape or pressure wash dirt and unwanted elements away. Alternatively, you can leave it to naturally disappear over the next few weeks (the weather and general footfall will gradually get rid of it).
