Fossa Substain WB is a low-maintenance, highly translucent, low-build exterior woodstain which produces a beautiful, translucent low sheen finish that highlights the grain of your timber. It's a direct replacement for the popular Sikkens Cetol BL21 Plus, and we think it beats it hands down too!
It's formulated using an innovative water-borne blend of alkyd and acrylic resins for good moisture vapour permeability, and includes selected preservatives and pigments to help protect your architectural timber from disfiguring moulds, fungi, and UV damage - which causes greying and denaturing of exposed wooden surfaces.
Fossa Substain WB exterior woodstain dries exceptionally quickly, often allowing you to apply a full three coat woodstain system in one day during good weather, which can save a great deal of time, as well as labour and equipment hire costs.

Choose one of our lighter coloured pigments if you wish to minimise any colour change, but do use a pigmented woodstain!
Coverage: 4 - 12 square meters per litre per coat, depending on surface condition and timber species.
Note: Actual woodstain colour achieved will vary depending on surface condition and timber species. Always apply a test application to an inconspicuous area to satisfy yourself as to suitability.
