Exterior joinery, fences, and sheds often need a preserver before colour or oil. Wood Finishes Direct stocks trade-trusted brands including Barrettine Premier Wood Preserver and Cuprinol 5 Year Ducksback — two customer favourites with different jobs.
Barrettine Premier Wood Preserver
- Deep penetration for bare or previously stripped softwood and hardwood.
- Use when you need mould, rot, and insect protection before a topcoat.
- Available in clear and coloured variants; always check the tin for whether a further decorative coat is required.
Cuprinol 5 Year Ducksback
- Wax-rich, water-repellent finish in matt colours — popular on fence panels and shed exteriors.
- One-coat coverage on many rough-sawn surfaces; re-coat when colour fades or water no longer beads.
- Not a substitute for structural repair — replace rotten boards first.
Quick decision guide
| Scenario | Suggested starting point |
|---|---|
| New bare fence before painting | Barrettine Premier (clear) + compatible exterior paint or stain |
| Colour and water beading in one step | Cuprinol Ducksback |
| Decking boards (foot traffic) | Preserver if required, then a decking oil such as Osmo UV Protection Oil |
