  • Overview


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.

Exterior wood to be treated must be clean, dry and free from surface coatings such as varnish or paint etc. Any such coatings must first be removed with a suitable remover.


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.


This solvent-based wood preserver should only be used in well ventilated areas. Care should be taken with the cleaning and disposal of any brushes, cloths, tins or other materials that have come into contact with this wood preservative.

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.

Note: This product is hazardous to Bees and should not be used on Beehives. Contact your local Bee keeping association for an alternative.

Drying Time

Up to 48 hours drying time, however temperature and humidity will effect duration.

Good value, good product
Second order of wood preservative, goes on well, easy to use, end product looks nice. Two coats makes the item look good as the first one absorbs really well - which is what you want for preservation. The second one finishes it off nicely. Will order again.

It's what was required.
The product is fine although it would be helpful if the 5 litre can had a pourer as it is a little awkward to pour easily into a container that a brush can be used with.

Excellent product....brings out the grain in the wood and you can see exactly where you have painted it on, despite being translucent, unlike some other products.

Very good value product
Used to treat garden panel fencing showing signs of weathering and algae. Easy to apply and absorbed well - the 5l can treated around 7 panels. The day after treatment could see an improvement in the overall condition of the panels.
