Product Description

N-Virol Algae & Lichen Killer is highly soluble in water and contains no acids or bleaches which could damage surfaces on which they are applied. It is an ideal maintenance product for schools, local authorities, and commercial premises.

N-Virol Algae & Lichen Killer works on contact and will kill algae, mould and other growths within typically 2-4 days. The secondary detergent action will help to gently clean the treated surface in the following weeks and months.

Note: Some species of lichen are resistant to treatment due to their impervious surface. To optimise the effect of N-Virol Algae & Lichen Killer solution, it is advisable to abrade the face of such growths prior to treatment (e.g., stiff brush).
