  • 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.

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.

Need to maintain your wood garden furniture in good order? Here's our blog post about keeping exterior furniture in tip top condition, which includes a small yet perfectly formed collection of remarkable facts about trees, wood and wood furniture.


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

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.

Just the job
Happy with the whole experience from ordering, delivery and using the product. Easy from start to finish!

 Cedar Red
Red cedar is the best colour
This attractive red cedar wood protection, must not be confused with the other stuff that makes your timber look like a red pillar box, which peels and flakes off in short time, leaving the wood unprotected to continue to rotting!
Catherine Hollis

Very easy to use, good finish, two coats as recommended are best
A great clear product when wanting to maintain original colour. Used on shed, brushed on for best coverage and used two coats as recommended . It is very thin, take care not to spill when pouring.

Great preserver, it penetrates deeply and gives great protection.
I first used this preserver as recommended by a local paint dealer when I built my shed 18 years ago. I have treated three times since and it is still like new! Expensive stuff but does a great job and lasts longer than the cheaper products.

Barrettine Premier Wood Preservative is an exellent product perfect for my job. Many thanks
I've just painted my large Bungalow with Barrettine Premier Wood Preservative and it went on so easy. I know it will keep out the 'harsh' Cumbrian winters weathers at bay for many years to come. What a wonderful product. Many Thanks. Arthur Hopkinson

Excellent product
Used on decking 5 years ago and recently again to restore the deck. Looked good after 2 coats but much much better with a 3rd light coat.

Excellent product, excellent service
This was my 2nd order from Wood Finishes Direct and I would recommend them to anyone. /The product is excellent, the company is great to deal with and the delivery service is prompt and friendly.

I like this product
I liked the colour and I found that it lasts a long time, the last time i stained the summer house was about 3 years ago. Does have an odour but not unpleasant (I do put a lot on though) until fully soaked in.
Jude 96

Always use this before you oil
The advice on the website is right. Use this first before the oil and the decking laughs at the rain!
Ingrid Easterbrook

Straightforward and easy to use
Base layer for our oak front door, wood preservative before using the high build wood oil.

Have been using it for years.
Excellent wood preserver for fences and sheds. Would highly recommend.
Helen Morris

Superb product!
Excellent product, giving an excellent finish and at a very good price. Lots of other similar products on the market, but costing a good ten pounds more!! I was delighted with it and intend firmly to stick with the brand every year from now on.

Impressed with product
Just put one coat on up to now but really pleased with the result and second coat going on soon. Measured the summerhouse and the first application has used exactly the amount expected from the calculation.
Michael Wong

 Summer Tan
Easy Peasy
Really easy to use, covers quickly, even with a small brush, soaks in immediately. Appears a little darker than pictures when first on, but lightens on drying to lovely shade as described. Would buy again from here as consistently the cheapest place, even with P&P added.

Very good fence , which we use all the time now.
A very good quality of fence paint as well as a quick delivery time, no waiting weeks. We'll done.
Martyn Johnson

Easy to apply. Survived the recent soaking from Hurricane Bertha.
We put several coats on some new oak beams over a 4-day period. They are forming a verandah, which as yet is unglazed, so fully exoposed to the weather. Early days yet, but it repelled the rain dumped on us by Hurricane Bertha at the weekend.
