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 guidance 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.

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.

This does what is says on the tin.
When applied, this preservative sinks in to the wood, especially across knots in the wood grain. Best stuff on the market at present that I can find.

Excellent product. Easy coverage and quick drying. Good even finish, I would recommend this to anyone wanting to stain and preserve wood.

Used for last 9 years.
Has kept my 3 sheds looking like new. Perfect wood treatment.
 Golden Brown
Easy to apply and covers well.
Painting a double slatted fence with a brush is near impossible, using a 5ltr pump up garden spray gets the job done in jig time. This is the third time the 20yr old fence has been treated, power washed first to remove green algae in garden area, left to dry and then sprayed. Colour goes on darker when applied but once soaked in dries to a nice golden brown, second coat slightly darkens it a bit more.

Good price, excellent delivery time, easy to use
Do not rate water based fence paint. So on the web I found this and are over the moon with my find, it is very easy to apply covers evenly, and penetrates deeply, and water runs off even after 1 coat. 100% satisfied with my purchase and have no qualms recommending this product.
Marie Foley
 Light Brown
Great colour, easy to use. Again very good value for money, can't rate it highly enough.
Used this as a base coat on a fence prior to applying a top coat. Easy to apply and dry's quickly to a good finish. Very pleased with the results so far.
Mary Wilson
 Golden Brown
Wonderful product that really works
My usual shed preservative coating was discontinued. I tried a substitute product recommended by local DIY store which was useless. The Barrettine is fantastic. It soaks right into wood, is quick and easy to apply and after a couple of coats, my shed is a lovely golden brown again.

Just what i was advised by the maker
This has worked well for 5 years

 Cedar Red
Fast service and good value for money.
Bought the product to maintain a red cedar greenhouse and Summer house. I was a little worried that the finish might have bee too red like some other cheaper products but the end result was better than I expected and complimented the wood perfectly. This product was recommended by the company I bought my red cedar greenhouse from and with next day delivery was cheaper than the high street and other online sellars. I highly recommend.

 Cedar Red
I have used this product many times over the years and would not look to use any other
I have always found this product to be first class and the standard never falls I would be more than happy to recommend it to anyone.
Michael Reynolds
Great product sensible price
Make sure you wear protective clothing when using this product. It does what it says on the tin and the clear solution does not stain the wood.
 Summer Tan
Quick delivery and does what its meant to
I've used this before on a wooden greenhouse that was supplied coated in Barretine, so it made sense to use the same product over the top. It goes on really easily and soaks right into the wood. Its solvent based rather than water-based so best with good ventilation
Richard Johnson
Excellent product
I have been using this product for a number of years. Being a thin preservative it is absorbed into the wood and is easy to apply. Many other products lie on the surface of the wood and make it more difficult to achieve even coverage. I dislike the intense and false (in my opinion) colours of many products, this clear preservative allows the wood to be seen. Until finding Wood Finishes Direct I had trouble sourcing the product, but now it is easy and with next day delivery.

Good stuff, coverage was great, smells lovely.

 Cedar Red
Excellent .really easy to apply
Used on new gates .very pleased with results good coverage with uniform penetration & colour.
Nigel Woodburn
 Light Brown
Easy to apply and resulted in a very good finish.
I used this product on my new unassembled 4.2 x 2.4m shed. It brushed on easily and the 10L was enough to do two coats with a small amount left for touching up if necessary. The finish is very good, rain just beads off.I would buy the product again. I think it's good value for money.
Richard Hodgkins
 Dark Brown
Good product easy to apply but does drip a lot!!! Happy with initial use but time will tell if it protects and lasts longer than other products that are on the market.
Easy to apply. very runny so take care with drips. how long it protects time will tell. certainly gives a good finish and appearance.
Jane Craig
 Summer Tan
Excellent with good coverage - makes garden furniture look like new.
This product gives excellent coverage and a couple of coats makes garden furniture look like new. It is very watery, but don't let this put you off as it absorbs into the wood so well. Will definitely buy again.

Excellent, waterproof and easy to use
Excellent product, very waterproof within an hour after applying and so easy to use, it's thin (like water) which makes it so easy to apply we are really impressed with this product.
