Hygeia Mosgo - 5 Litre is a fast acting surface biocide for killing moss on tarmac, slate/tile roofs, and on all stone and concrete surfaces. It should be diluted as per the instructions and applied using a sprayer or brush under conditions of good growth when rain is not expected. After 3 - 4 days if applied correctly, the dead moss can be brushed away. Severe moss growth may require a second application. You can expect 5 litres to achieve coverage of 62.5 metres squared.
