Barrettine Premier Wood Preservative is an all-in-one, spirit-based wood preserver for the treatment and prevention of dry rot, fungi, mould and protection against woodworm.

Quick and easy to apply with a brush or roller. Harmless to plants and animals when dry. Can be overcoated with Barrettine Log Cabin Treatment or Decking Oil for additional protection.

  • 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.

Wood Preservative Colours

Please Note The colour swatches shown above are for guidence only as the final colour is dependent on the type and age of the timber being treated. The initial colour tends to be stronger and brighter when first applied but will 'tone down' over time as the surface of the timber is subjected to weathering.


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.


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 primer for decking oil
Easy to apply but shame cans don't have a pouring spout

Fantastic product
So easy to apply and provides a proper preservative finish to wood. Re-coated after last year but it should now last for years. Don't waste your money on DIY fence products which just sit on the surface, do the job properly with Barrettine.

A great product
This is the first time I have used Barrettine Wood Preservative and I've been delighted with it. I have used it on a new shed and it really soaks well into the grain of the wood. It's easy to use and has given a great result.

The product Iis excellent and the service second to none. I have been using wood finishes direct for a couple of years and am always impressed with the speed of delivery and as a sole trader it's always handy to know exactly at what time the delivery will arrive.

Excellent product
Application was fast and easy. Used this for my new log cabin. Managed to get one coat on and 12 hours later it rained. Water beaded up immediately. Second coat a few days later and the cabin looks great. Waiting now for some fine weather and have bought the log cabin treatment to put on next. Can highly recommend this wood treatment. Will definitely use it again.
