Shed Oil

Why use an oil based shed treatment?

Protecting a garden shed with an oil based shed treatment provides excellent protection against weathering and water ingress. Available in clear and coloured formulations, they are easy to apply and maintain. Wood oils help to nourish shed timbers keeping them supple, preventing swelling, cracking and splitting. They will also not crack, flake or peel off, unlike some types of exterior wood paint and varnish.


Clear wood oils applied over a clear shed preservative will retain the natural look of the shed albeit with a slightly darker, almost damp like appearance. Alternatively, a coloured shed preservative can be used to stain a shed prior to over-coating with a clear wood oil. This combination of shed preservative and wood oil gives sheds the best protection from biological threats such as mould, algae and insect attack. It also provides the best protection from the damaging effects of weathering such as wind, rain, sun and temperature extremes.

Coloured wood preservers tend to come in shades of brown, green and black. If a more colourful finish is desired, sheds can be treated with a clear wood preservative, then over-coated with a semi translucent or opaque coloured exterior wood oil. Exterior wood oils are available in many colours including shades of blue, green, grey, red, white and more.


What is a shed oil?

There are a number of exterior wood oils that are perfect for use on sheds, log cabins and wooden summerhouses. Traditional oils such as Danish Oil and Teak Oil can be used but these require numerous coats and regular re-coating to retain their weather proofing properties. Other specialist external wood oils are made from a blend of waxes, oils and resins which makes them durable and long lasting, usually only requiring 2 coats and maintaining every 2 to 3 years, dependent on the shed location and exposure to the elements. Many exterior wood oils also contain UV filters which are added to protect the natural colour of the shed timbers from the bleaching effects of the Sun’s UV rays. The additional cost of these specialist wood oils over traditional wood oils is worth it because of the protection they provide and the reduced maintenance periods.

Cost effective alternatives

A great alternative to a specialist exterior wood oil is decking oil. Decking oils are also formulated from blends of wax, oil and resins to provide weather protection and durability. After all, they’re also designed to withstand foot traffic and other liquid spillages. Many decking oils also contain UV filters and are available in both clear and coloured formulations.
