Keep your outdoor timber structures in top condition for longer by applying Barrettine Wood Protective Treatment. The oil/solvent-based formula penetrates the wood deeper to provide longer-lasting protection.

It reduces decay, swelling and twisting, and contains a biocide film preserver that prevents the surface growth of mould or algae - your timber will stay stronger, and look better. The treatment also provides fade-resistant UV protection, making it perfect for use outdoors on your shed, fence, trellis, pergola or gazebo.

A 5L tin goes a long way too, offering you up to 30-40m² of coverage on rough, sawn or smooth timber. The low-odour formula is ready to use, so there's no time wasted with dilutions. A quick and easy application is all that's needed to protect your pre-treated wood from the elements.

• Suitable for use on pre-treated rough, sawn or smooth timber
• Oil/solvent-based formula penetrates deeper for greater protection
• Prevents the surface growth of mould or algae
• Reduces the decay, swelling and twisting of wood for longer-lasting protection

• Follow suggested retreatment intervals and use on suitable exterior timber such as joinery and garden structures to maintain long-term protection.
