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.

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.

Easy to apply quick drying
Keeps wood looking fresh. Colour lasts.
Richard Downey

Great quality product. Very pleased
With the right product the job is easy. And easy it was. This stuff goes on very quickly - like painting with water. Wore a mask and gloves as it's fairly potent stuff. Close the doors and windows of your house too to avoid the smell indoors. Despite the pong, it gave a really good finish after just one coat. I'll give it another coat in a couple of days to be on the safe-side. Hopefully it should last a few years. It was a bit more expensive than I was expecting but it should last longer than cheaper brands - and if it saves me having to redo it again in a year (like my neighbour on the other side of the fence who used a cheap product which I'm convinced has washed off in the rain) then it will be well worth it.

More effective than water based treatments
Good product. Good price. Much better wood penetration than water based treatments hence more effective.

It's good stuff.
I've used this on my shed since I bought it about 14 years ago because it was recommended as the best by the shed maker. It has worked because my shed is still as good as new. This year I decided to add Log Cabin Treatment as well, this does make it look good and the moisture beads and runs off just like it does off a well waxed car.

Excellent product
Great two coats on 6×10 shed, plenty left and looks great.
 Holly Green
Does what it says on the can.
Have used this product for many years both in the trade and retired. Easy to apply at a reasonable price.

It was just the product that we needed
This is the third time we have used this product on our garden shed, each time it brings the shed up as new and the the wood is looking as good as when we it was new, our shed is over 10 years old.

Good quality wood preservative
I've used Barrettine wood preservative on a couple of long fences and it works a treat. It's easy to apply and works well. Plus, the delivery just can't be beaten!
Jenny Dawe
 Golden Brown
Excellent wood preservative
I bought this preservative on the recommendation of my father. I am so pleased with it - the colour is perfect and the application is so easy.
Malcolm Kent
 Golden Brown
Great preservatives
Will only use this product when treating my decking, all the so called decking stain/oils are water based, so will never last, using an oil based treatment will last much longer as it soaks into the wood.

Easy to apply and an excellent product
I purchased this product to protect my 10ft x 6ft shed. I gave it 2 coats and still had some left. It was very easy to apply by brush and absorbed into the wood immediately giving a very good finish. The water now just runs off the wood.I am delighted with this product
 Golden Brown
Great product
Good product - goes on well and I'm confident it gives good protection.
Alison Campbell
 Golden Brown
Easy to apply and waterproof after one coat but have applied required amount. Worth every penny to protect expensive log cabin which hadn't been looked after as it should. Will regularly use this excellent product and not waste money on cheaper products.

John Gordon
