Barrettine Wood Preserver Colours: Which Finish for Your Project?

Unlike opaque paints that sit on top of the wood, Barrettine Wood Preserver is a semi-transparent, spirit-based treatment. This means the final look is a partnership between the added pigment and the natural grain of your wood. Because the grain remains visible, every result is slightly unique to your specific project.

The “Natural” Classics include Clear, Light Brown, and Golden Brown, which are designed to celebrate organic beauty while providing full biological protection. For a more contemporary feel, the Modern Earth Tones and Contemporary Cools—such as Dark Brown, Holly Green, and Black—offer a designer edge that can help structures blend in or stand out.

We use high-quality pigments in every shade to provide a lasting, fade-resistant finish. However, remember that Clear lacks UV pigments; therefore, use it as a primer or on wood you want to silver naturally over time.

The swatch on a tin is only an indication because wood species and condition play a massive role in the final result. Lighter woods like Pine show pigments brightly, whereas older, weathered timber will “muddy” the shade and often turn out much darker.

Texture also changes the visual outcome; rough-sawn timber is more absorbent than smooth planed pine, leading to a more intense and saturated colour. To ensure a professional finish, you must account for these variations before committing to a large 25L tin.

Always consider the surrounding landscape and brickwork when selecting a tone. Shades like Red Cedar offer a rustic, autumnal feel that complements traditional masonry, while Holly Green helps rural sheds tuck seamlessly into the foliage.

The number of applications you apply will significantly change the opacity and richness of the wood preserver. One coat provides a subtle, light tint, while two coats is the standard for achieving a balanced, rich finish with full biological protection.

Applying a third coat will significantly deepen the pigment and increase the water repellency of the wood. Furthermore, each additional layer increases the “sheen” of the timber from a flat matt to a more lustrous satin finish.

For trade professionals, achieving a uniform colour across a large fence line requires consistent application across all panels. Using a high-quality brush, like the ProDec 4″ Flat Shed & Fence Brush, ensures you can work the pigment evenly into the grain for a professional result.

To ensure the pigment “bites” into the wood for a true-to-colour finish, the surface must be dry and free from dirt or previous coatings. Varnish or old paint will block the spirit-based formula, leading to a patchy and uneven appearance.

If your timber is old or greyed, we strongly recommend using Barrettine Wood Reviver first. This essential step removes damaged cells and brings the timber back to a “bright” state, ensuring a much better colour match to the chosen swatch.

Never treat an entire fence line without performing a patch test in an inconspicuous area. Allow the test patch to dry for 12–24 hours to see the true, settled colour before proceeding with the rest of your garden project.

Crucially, once the treatment is completely dry, all Barrettine colours are harmless to surrounding plants and pets. However, the wet product remains toxic to bees; consequently, it should never be used on active beehives or in areas where bees are currently swarming.

Regarding clean-up, ensure you have White Spirit on hand for all brushes and equipment, as water will not remove the spirit-based oils. Additionally, if you are using the preserver on garden furniture, it is advisable to perform a ‘rub test’ with a lint-free cloth to ensure the colour has fully settled before use.

Please note that the standard Wood Preserver is not recommended for high-traffic decking. Instead, for horizontal surfaces like decks, you should use Barrettine All-In-One Decking Oil, which is specifically formulated to withstand the constant friction of foot traffic.
