Before application remove excessive dirt and soiling, large areas of algae, lichen or fungi using an appropriate fungicidal wash or cleaner designed for the job. Wood that has been wood-stained, painted or vanished should be stripped back to bare wood and treated as bare wood. Do not use this product to treat wood destined for in ground contact use. Ensure that timber used in ground contact has been pre-treated especially for such use.
Apply 2 even coats with a brush. Leave the first coat to soak in before applying the second but reapply before the first is fully dry (typically 2-6 hours). Leave 16 hours for the second coat to dry before painting, staining or vanishing. Do not spray.


The drying time is 16 hours. Drying times can vary depending on the nature of the surface and the weather conditions.


After use: remove as much product as possible from equipment before cleaning with water. Do not use or store in extremes of temperature.
