Garden Fence Oil

Using a fence oil is a great way to protect and preserve fence panels and posts from the elements and weathering. Wood oils not only keep garden fences looking better for longer, they also nourish and feed the wood to keep it supple and water resistant. This helps to prevent fence panels from drying out, cracking, splitting and warping.


Preserving then oiling a garden fence provides excellent weatherproof protection

Why oil garden fence panels and posts?

As with wooden sheds and decking, garden fences exposed to weathering and sunlight will eventually loose any natural wood oils from the fence panel timbers. This can result in warping, cracking and splitting as well as water ingress, mould, algae and wood rot.

Which wood oil can be used on fence panels?

Exterior wood oils are both durable and easy to maintain. Made from a blend of oils, waxes and resins, they are designed to penetrate deep in to the fence panel timber to provide long lasting protection.

There are a variety of exterior wood oils that can be used to protect garden fences but the one needed largely depends on your preference for a clear or coloured finish, one that contains UV filters or a biocide / fungicide to help combat mould and algae.

Decking oil used on garden fence

Coloured decking oils are a great way to colour and protect garden fence panels

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

  • 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 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 like a paint. 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 fence 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’s 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. We always recommend that a test area is done before embarking on any large scale project to ascertain the final colour and finish of the product to hand.

There are a multitude of fence treatments that will colour and transform new and old garden fences including a wide range of fence paint colours and fence stains. For information and advice on other garden fence treatments click here.
