Barrettine Wood Protective Treatment

Ideal for treating outdoor treated timber structures such as sheds, fences, trellis and pergolas, Barrettine Wood Protective Treatment is a low odour wood sealer for rough, sawn or smooth timber. It contains water repellent resins and a biocide film wood preserver to stop mould and algae surface growth. These help to reduce decay, swelling and twisting of the wood. The pigments contained in Barrettine Wood Protective Treatment offer great UV fade resistance and will help to protect the structure from sun damage.

• Matt to Satin finish
• For use on most external pretreated timbers
• Prevents surface growth of mould /algae
• Harmless to plants and pets when dry
• Water repellent
• UV fade resistant colour pigments
• Long lasting protection

Not suitable for garden furniture unless over sealed

Ensure that the surface to be treated is clean and dry, and free from varnish, paint, wax etc.

• Before application, the wood must have been dry for 24 hours and rain should not be forecasted for at least 48 hours after application to get maximum benefit from the treatment.
• Can be applied directly to pressure treated / preserved wood. Apply to unsealed wood. If the wood has been varnished or painted, these coatings must be removed prior to applying this treatment.

Always follow the manufacturer's instructions found on the tin. The final colour finish can vary considerably due to the age, type & condition of the timber being treated. We advise to carry out a test area first in a discreet area to make sure you're happy with the final colour once it has dried.

• Shake well before use for at least a minute, and during use to keep the colour uniform.
• Can be sprayed with a traditional pump action garden style sprayer with viton seals. Can also be sprayed using an airless sprayer (Wagner or Graco type) ideally using a minimum 1mm flat fan tip nozzle (9 – 11 thou tip). Thoroughly clean the sprayer after application with white spirit and then oil it to protect the tip and moving parts (as per manufacturer’s instructions).
• Apply a minimum of 2 coats to ensure complete coverage of the wood.
• You will get a greater depth of colour with more coats, and more protection / water repellency and increased film depth on the surface, providing more of a sheen finish.
• Drying time is usually 24 - 48 hours under normal weather conditions. Low temperature, humidity or certain components of wood may increase the drying time.

Q. Does Barrettine Wood Protective Treatment preserve wood?

A. Barrettine Wood Protective Treatment is designed to penetrate deep into the wood, nourishing and protecting it from within. It helps to prevent the wood from drying out, cracking, or splitting, which can be caused by exposure to sunlight, moisture, and temperature changes. Additionally, it enhances the natural beauty of the wood, giving it a richer and more attractive appearance.

Q. Does Barrettine Wood Protective Treatment weatherproof wood?

A. One of the key benefits of Barrettine Wood Protective Treatment is its excellent weather resistance. It forms a protective barrier on the wood surface that helps to repel water, preventing it from penetrating into the wood and causing damage. This weatherproofing capability is particularly important for exterior wood surfaces, such as fences, decks, sheds, and garden furniture.
