Fence Treatment FAQ's

Back to FAQ Index

Does it matter if my fence panels are rough sawn or smooth?

In terms of the amount of fence treatment required, yes it does. This is because rough sawn woods are very porous and absorb more treatment than smooth planed wood. This should be taken into consideration if treating a large area of garden fencing. Our Barrettine Premier Wood Preservative page has colour swatches that show the potential colour difference between rough and smooth wood. This illustration should only be used as a guide and not as a substitute for doing a test area.

Because rough sawn fence panels absorb more wood finishing product than smooth planed wood, any colour pigment in the product is likely to look stronger or darker than it would on a smooth piece of timber. Always do a test area to be sure of the colour and final finish before starting any project. It's also worth noting that although wood finish colours may initially look stronger than expected when applied, they usually 'tone-down' after several weeks or months of weathering.

Do I have to use a 'shed and fence' specific wood preservative?

Most wood preservatives are similar in what they do even if specific formulations can differ slightly. Products labelled as 'Shed and Fence Preserver' are often no different from other exterior wood preservers. Using a general purpose exterior wood preservative such as Barrettine Premier Wood Preservative or Ronseal Total Wood Preservative is absolutely fine.

What sort of wood oil should I use on my garden fence?

Using a wood oil on a garden fence is a great way of prolonging the life of fence panels and posts. Decking oils are perfect for use on fence panels as they help to protect the timber from cracking, splitting and warping. They provide excellent weather resistance and are available in both clear and coloured formulations.

When treating a new fence or a bare wood one that hasn't been treated for a number of years, we highly recommend treating the fence panels with 2 coats of an exterior wood preservative prior to oiling. This helps to protect the timber from biological threats such as mould, algae and wood boring insects.

How can I clean green algae from wooden fence panels?

Green algae can usually be cleaned from fence panels by first brushing with a stiff brush or broom to remove as much of the surface growth as possible, then treating with a mould and mildew cleaner such as Barrettine Mould and Mildew Cleaner. Fence panels that have been become heavily soiled with biological growth may require a second treatment.

Once cleaned, treated and allowed to dry, fence panels should then be treated with a wood preservative, this will help to prevent future growth of mould and algae.

What is the best fence paint?

Garden paints that are suitable for garden fences come in a wide range of colours and formulations. All are designed to colour and protect garden fences from weathering. Three popular products we offer are Cuprinol Garden Shades Paint, Ronseal Garden Paint and Barrettine Country Cottage Shades, both of which are ideal for wooden garden fence panels and posts.

It's worth noting that there are a wide range of wood preservatives and exterior wood oils that also colour and protect garden wood and can also be used on wooden fence panels and posts. See our full range of garden fence treatments here.

How much garden fence treatment do I need

The amount of garden fence treatment needed for a given project can vary and is dependent on the type of product being used, the area of wooden fence to be treated and to a degree, the type and the condition of the wood. For this reason, each of the product pages on our site have a handy 'coverage calculator'. Simply calculate the area to be covered, in either feet or meters and our coverage calculator will give you an estimate of how many litres of fence treatment are required. It's worth remembering that the figure given is an estimate as factors such as the porosity of wood, condition and application method can all have an influence on the coverage of a product. That said it's rare we hear from customers saying the amount of product ordered was not enough.

What is the best way of achieving a solid black garden fence finish?

Black fence finishes have become more popular as they provide a striking contrast against the green of grass, trees and other garden plants. Read more about achieving the perfect black wood finish in our blog.
