In cases of severe moss build up on surfaces, remove as much as possible by physical means or break up the surface before proceeding as below. Some species of moss/lichens are resistant to treatment due to their impervious surface. To optimise the effect of n -virol Algae & Moss Killer solution it is advisable to abrade the face of such growths prior to treatment. (E.g stiff brush).

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 & Moss 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.
For maximum effectiveness n -virol Algae & Moss Killer should be applied when surfaces are reasonably dry and rain is not imminent. Treatment should be in wind free conditions to minimise spray drift. 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 by brushing or washing or by using a power spray. A second coat of n-virol Algae & Moss Killer may be necessary. Retreatment may be necessary to prevent re-growth. Factors that can shorten the treatment life are:
1) Dense substrates that do not absorb the fluid.
2) Surfaces where dirt/leaves are allowed to accumulate.
3) Persistently damp areas.
Internal Treatments (mould control)
For interior work, traces of mould and algae should initially be removed by normal cleaning methods followed by an application of n –virol Algae & Moss Killer. On relatively non-porous surfaces such as painted plaster or ceramic tiles the application rate can be reduced and the treated solution can be applied by a fine mist spray. Please note: Mould colonies can cause damage to underlying substrates (paint, wallpaper). Care should be taken to ensure damaged decorations are removed prior to treatments and or new coatings being applied.
As soon as the surface is dry the decorative finish can be applied. Treated timbers (i.e. decking) can be over coated when dry with a range of decorative / protective paints etc., if required. With certain water based coatings, to ensure compatibility, check a small area first.
