Please be advised Barrettine have released a new formula of this product, in a newly designed tin. Should the colour you order be out of stock in the old design, you will recieve your chosen colour in the new design container.

Barrettine Wood preservative is the perfect undercoat for any exterior project including but not limited to decking (where a top coat of Decking Oil will offer the ultimate protection). This new formula now includes protection against wood boring insects.

Barrettine Premier Wood Preservative contains a small amount of wax (Less than 1.5%). Water-based products or paints should not be used on top of this product as the wax content will likely repel the water based product, preventing it from bonding with or penetrating into the timber.

Note: Under normal conditions, as long as the wood being preserved has also been overcoated with an exterior wood oil such as Log Cabin Treatment, Decking Oil or other exterior wood oil initially, and every one to two years thereafter, the wood will not need to be treated with preservative again for at least another 5 years.

Wood that has not been oiled, or oiled in the last 2 years can be re-coated with preservative every other year if desired.

Need to maintain your wooden garden furniture? Here's our blog post about keeping wooden garden furniture in tip top condition, which includes a small yet perfectly formed collection of remarkable facts about trees, wood and wood furniture.

Exterior wood to be treated must be clean, dry and free from surface coatings such as varnish or paint etc. Any such coatings must be fully removed by sanding or with a suitable remover before applying the wood preserver.

Easily applied with a brush or roller. If you have a large area to finish you might like to consider the shed and fence spray system - although not recommended due to the solvents perishing the spray washers it is possible to use the Shed and Fence Spray System for a day, so provided you can complete your project within a day this is still a good, cost effective option.

Barrettine Wood Preservative should be stirred thoroughly before application. Allow to dry between coats. End grain of timber should be treated to saturation for the best protection. 2 coats of wood preserver offer the best protection on sawn / rough timber while up to 3 coats can be applied on smooth timber.

Application brushes should be cleaned immediately after use with Barrettine Brush Cleaner or white spirit and before the product has had chance to dry. Dirty brush cleaning solution should be disposed of properly and not poured down sinks or into drains.

Q. Is this all I need to protect my summer house?

This product is commonly used on its own on sheds and fences and other exterior items constructed of rough wood, however for a total treatment we recommend over-coating with Barrettine Log Cabin Treatment or decking oil for added water repellency and weather protection.

If protecting the natural colour of the wood is important, use the clear preservative then overcoat with Osmo UV Protection Oil Extra or Fiddes Exterior High Build Wood Oil.

Q. Can I use Barrettine Wood Preservative on a chicken shed and dog kennel?

Barrettine Wood Preservative is perfectly safe to use on any surface that comes into contact with animals when dry. This includes but is not limited to dog kennels, chicken sheds and houses, horse stables and more. It's important to remember that this wood preservation treatment should be over-coated with a suitable exterior wood oil or decking oil. Animals should only come into contact with the surface of the wood when both the wood preserver and oil have fully dried.

Had no problem applying the product and it dried out to a nice golden colour I used approximately 16 litres which covered the area close to the coverage detailed on the can by Mr Michael Thomas

Although more expensive than some fencing products on the market you get what you pay for. In appearance it looks far superior to any other product and I'm sure will be longer lasting. It is easy to apply and penetrates into the roughest of surfaces. The first coat sealed the timber really well and consequentially the second went a lot further.

Very easy and quick to apply by Mrs Denise Thompson

Id definitely use this product again I bought the clear wood preserver to protect my newly built garden studio. Initially I wanted to age the wood using the vinegar wire wool method and was at a loss at what product to use to protect the wood. I didn't want it to go orange! so contacted the supplier this was recommended although they had never had a request like mine before! After a lot of sampling sadly it didn't work the wood went brown and I was after that weathered grey look. I just applied the preserver to the virgin wood, and have to admit it looks beautiful, went a slightly darker shade of pine maybe it'll weather eventually how I imagined but for now I'm chuffed to bits.

Essy to apply, nice colour , slightly waxy finish to repel water by John Rickett

Easy to see where the previous coat has been applied so getting even second and third coats is no problem. Drips and brushes clean up well with paraffin, no real need to use white spirit

Good to apply, good coverage and good colour by Mr Jon England

easy to apply and covers well. Colour (black) needed a second coat over pressure treated wood as it does not soak in as well as it would with untreated. Hope it protects my shed in the long term.
