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.

Barrettine Premier Wood preservative is ideal for smooth or rough exterior timber including fences, sheds, decking and more.

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.

  • Until dry - Treated surfaces can pose a fire risk.
  • Not suitable for use on garden furniture unless over-coated with an appropriate sealer i.e exterior wood oil or varnish.

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.

Neil Chisholm
Great product and advice. Well worth the money.
Called to ask advice and staff were really helpful and knowledgable. Product dried in very quickly on the surface and the rain beaded even after 1 coat and only 1 day to dry. Will add another coat once the temperatures rise a bit. Experience and product recommended.

The order handled efficiently & delivery was super fast the product was great
I used the wood finish with a spray applicator. I treated both sides of a 13 panel 6'x6' fence, a gate and 12x6' shed and still had a whole tin left over from the 8 I purchased. Colour was spot on and the treatment was excellent.
 Golden Brown
Very good.
It was easy to apply and covered the shed really well. Unfortunately it only had 12 hours to dry but the water still 'beads' when it rains even though it stated it needed 72 hours to dry. I will give it another coat in the spring, but overall very impressed with product.
Ioan Davies
Very reliable basic preserver at a great price
I have used this wood preservative for 30 or so years of internal and external work with timber. My second house was built in 1762 and had no damp course so I routinely used wood preserver on all internal structures. I have taken apart structures exposed to damp (not wet) conditions 30 or so years after I first treated timber to find everything in very good order. For external applications I use this Premier wood preservative as a base coat, followed up by prolonged soaking in more aggresive external preservatives (e.g. creosote) for below ground usage.

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.
