Cuprinol Trade External Wood Preserver 5 Litre Rustic Green

Cuprinol Trade External Wood Preserver is a lightly pigmented, water-based treatment designed to protect exterior timber from the elements. It is formulated for use on both rough-sawn and smooth garden wood, including fencing, cladding, sheds, greenhouses, and summerhouses. The product contains active ingredients that penetrate deep into the timber to provide a protective barrier. The preservative offers long-lasting defence against weather damage, rot, decay, and blue stain fungus. Its water-based composition makes it safer to use around plants and gardens compared to solvent-based alternatives. The formula dries relatively quickly and leaves a matt finish in a rustic green colour, adding a subtle tint while protecting the wood. It is specifically intended for exterior wood surfaces only. This treatment is ideal for homeowners and gardeners looking to maintain and protect outdoor wooden structures. It is practical for seasonal maintenance or for treating new timber installations. The 5-litre size provides sufficient coverage for multiple projects or larger areas, making it a versatile choice for general garden woodcare.
