Application Notes
- Read the product label before use
- Following dilution application can be either with a low-pressure pneumatic sprayer (course spray) or by using a watering can with a rose attachment
- For small items such as gravestones etc, N-Virol Algae & Lichen Killer solution may be applied by a brush provided the solution is flooded generously into inscriptions and other cavities
- Always direct the spray away from the body; do not spray directly overhead
- 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)
- Once existing organic growth has been killed by an initial application (2-7 days) the treated surface will not need to be washed after the application of the product. However, in cases of severe contamination, this dead material should be removed using a stiff brush
