  • 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.

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 would recommend Log Cabin Treatment for added water repellency and weather protection, or Fiddes Exterior Wood Oil to also reduce the likelyhood of your log cabin from greying.

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. 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.

 Light Brown
So easy to apply and gives you confidence that the wood is protected
First class product. Forget the overpriced water based rubbish. If you want to seriously protect your wood, look no further.
Ann Hutchins

Excellent product.
When we bought the summerhouse, this was recommended to us by the firm. We choose the Clear this time, so it didn't darken the wood anymore. Brilliant product!

Buy with Confidence
3rd time I've bought this product, best results with the spray bought from WFD. (You need goggles and a mask) At first it seems too thin, shake the can really well first, give it two coats and it gives a very satisfying result. Fences soaked it up. Quite low odour. First class delivery from DPD and easy to use website. Recommended

 Dark Brown
Great product. Good coverage. Gives excellent finish.
Having used various similar products over the years, in my opinion Barretine Premier Wood Preserver - Dark Brown is the best.
Gaynor Arnold

 Golden Brown
Easy to apply, great coverage and colour
Quality wood preservative, easy and quick to apply. Hopefully keep my fence looking fresh for a lot longer than water based fence care.
Olivia Stephens

Easy and straight forward to use
This product was very straight forward to use and hopefully will do the job over the next few years
Dave Shorten

 Light Brown
Excellent coverage, good colour.
Used this product a few years back. It was excellent then, and things haven't changed. Use a brush not a roller to paint this on. You'll cover a lot more area with a brush. Excellent product would thoroughly recommend.

 Summer Tan
Good stuff
I have just stained my new fence, two coats (summer tan). Although the colour is a little darker than expected I'm hoping it will lighten in time. A little smelly but goes on well. Will definately use again.

 Summer Tan
A high quality preservative.
I have used this on my workshop since it was built and it has a more satisfying finish than any other product I've used in the past.
Colin Trott

 Golden Brown
Superb natural colour for fences.
We wanted a natural colour to our fencing and Golden Brown gave us exactly what we wanted. Easy to apply, soaks in well and looks as though it should last. I was dreading this but it a job well done and looks good.
Peter Blackwell

As above price and ease of application plus appearance
Have a bespoke gate which requires a twice yearly application this product fits the bill perfectly
Peter Blackwell

 Summer Tan
Ease if application coupled with competitive price
Initially I was applying sadolin, however, it took a long time to apply. With the spirit based protection it was so much easier and quicker our cedar summerhouse looks fantastic. I intend to apply each year now in order to maintain the rich appearance.
Jiill Burrage

 Summer Tan
Easy to use and long lasting results
This is the best wood preservative we have ever used; the results are excellent, good coverage and very long lasting. Gives a really luxurious finish. Will certainly use again and again.

 Holly Green
Good product
As others have said it has an odour and the can could do with a spout as it spills when pouring. Other than than it does the job.
Terry Jolly

 Summer Tan
Rich colour and easy to apply
My summerhouse has been re-coated with this wood preservative, and the colour is excellent. More importantly to me is the protection of the timber from rot and decay. The Barrettine product is first class in this department.
John Nixon

 Summer Tan
Works wonderfully and doesn't flake.
I chose this product and have used it successfully on deck boards and gates and wooden structures including sheds and greenhouses. The joy is it just fades and doesn't flake and cause a problem later on. Yes, I have to recoat more frequently but it's so thin and penetrates so well and dries so rapidly that it just is much easier in the long run.
Neil Butleigh-Jones

Good product and excellent service from WFD.
Very pleased with the product which covers well and is very economical. Will have to wait and see what the durability is like but no reason to doubt it will be fine.
