Garden Fence Oil

Using an oil-based fence treatment is a great way to protect fence panels and posts from the effects of weathering. Fence oils not only keep garden fences looking better for longer, they nourish and feed the wood to keep it supple and water resistant. This helps to prevent fence panels from drying out, which in turn helps to prevent fence panels from shrinkage, cracking, splitting, and warping.


Preserving then oiling a garden fence provides excellent weatherproof protection

Why oil garden fence panels and posts?

Any garden wood exposed to weathering and sunlight will eventually lose its natural oils. This applies to garden sheds, fences and decking. When this happens, timbers become vulnerable to cracking, splitting, warping, and shrinkage as well as water ingress, mould, algae, and wood rot.

Which wood oil can be used on fence panels?

There are a variety of clear and coloured exterior wood oils that can be used to protect garden fences. Which one largely depends on personal preference for a clear or coloured finish. Some oils contains UV filters, biocides and/or fungicides to help combat mould, algae and other biological threats.

Clear or coloured fence oil?

Decking oil used on garden fence

Coloured decking oils are a great way to stain and protect fences

Deciding on whether to use a clear or coloured wood oil may depend on the age, colour and condition of the fence.

  • To preserve the colour of new fence panels, treat with a clear wood oil that contains UV filters
  • To allow wood panels to turn grey / silver, use a clear wood oil that doesn’t contain UV filters
  • To stain fence panels treat with a coloured wood preservative then a clear wood oil
  • Alternatively, use a clear fence preserver then a coloured wood oil or decking oil

Choosing an opaque or translucent fence finish

For most, keeping the appearance of the wood grain is important, that’s why most coloured exterior wood oils provide a translucent wood finish where the detail and pattern of the wood grain is still clearly visible. There are however a few products that give an opaque finish, these are generally used on smooth planed fences such as picket fences to give a paint like finish. The beauty of an opaque wood oil is that although it looks like a paint, it will never crack, flake or peel off. An example of this is the excellent Osmo Country Colour.

Top Tip

The final colour of a wood oil on a garden fence is largely affected by the type, age, condition and colour of the wood that makes up the fence panels. If the wooden panels were bought at a different time and from different places, chances are that they will naturally vary in colour to some degree even if they are the same type. Because of this it is important to be aware that even by staining them with a coloured or pigmented wood oil, the end colour may vary from panel to panel and to that shown on the tin. For this reason, always do a test area to assess the colour and final finish before starting on any large scale project.
