Allback Zinc Oxide is important to ensure that you add Zinc Oxide, when applying the first coat of Allback Linseed Paint on external surfaces. This should not exceed 20% (parts per volume) of the first coat of paint. The purpose of the Zinc Oxide is to create a barrier against possible mould growth. Please ensure the paint is mixed thoroughly to avoid drying problems, its application should be worked onto the timber very thinly and thoroughly. It is only necessary to add this to the first initial coat of paint, however, it can also be added to any subsequent coats and will not greatly affect the colour of the paint if mixed correctly.
For existing painted surfaces where mould growth has become apparent, clean the surface with Linseed Soap and apply one more coat of the original paint, including Zinc Oxide.
