Product Information

Natural Oil Woodstain is a transparent wood stain for vertical exterior timbers, such as timber cladding, garage doors, pergolas and other exterior trim. Extremely weather and UV resistant, with a satin finish.

Available in 18 colours. 

Woodstain is a 1 or 2 coat system, depending on the desired level of transparency.

Natural Oil Woodstain is not recommended for timber patio furniture or horizontal surfaces such as decks, as the product contains biocides.

Coverage is approximately 26 square metres per litre on dressed timbers, and 12 square metres per litre for rough sawn or band sawn timbers. The coverage rates also depend on whether the timber is a hardwood or softwood.

Renovation is easy, with a 1 coat application to the cleaned, dry and intact surface after approximately 24 months -depending on the timber's exposure. Where the timber is fully protected from the sun and weather, the time between re-coats will be longer.

Additional Advice:

Osmo's Natural Oils Woodstain is a transparent finish, 1 or 2 coat system, with a maintenance re-coat after approximately 9-12 months depending upon the timber's exposure. The number of initial coats depends upon the degree of transparency you require on the timber. One coat is quite transprent, but the protection level will not be as good as 2 coats, however, with 2 coats, the finish will not be as transparent.

A trial is always recommended first to determine suitability.
