  • 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

Seems very effective
Its early days, review I guess should be in 5-10yrs!! very easily absorbed by the wood and rain just rolls off so looking good.
Jason C, Essex

Good service, prompt delivery...easy to use
Very helpful staff. Easy to use website. I bought the Manns sprayer to apply as would've taken too long to do my log cabin with a brush...despite the warning, the seals lasted til 2nd coat applied. We'll see if sprayer still usable in 2 years time, if not will buy another. Yet to see if preservative works...time will tell. But very happy so far

Brought the grain of the wood up beautifully on a plain fence.
Summer Tan - I have a brand new fence that needed a good quality treatment. I have been looking around for a while and reading up on the different preservatives that are out there, wow who knew there were so many :0! Anyway decided to go with this one as it really is probably the best on the market and at a reasonable price. Most preservatives out there do not have the protection that this one contains and I found that most are a little more than just paint, not much protection other than weather proof. Yes I will still need to weather proof my fence after using this preservative but I can now do so knowing the wood is protected within. The colour was a huge bonus and not too dark either. The grain is highlighted and looks beautiful. I intend to buy a clear weather proofing, the same brand to keep my fence looking brand new for year to come. Being a new fence it soaked up this preservative like a sponge so buy a little extra to make sure you have enough. I had been putting this job off as I've never painted a fence before and thought it would be hard work but this goes on like a dream and the results are instant. Can't say how it will look next year but I'm pretty confident it will be a job I don't have to do again for a long time.

Easy to use but watch the solvent smell.
An essential product that is easy to apply, no mess, and the clear product does not stain the wood.

Good product
First time I have bought Barrettine and slightly dubious as had never heard of it before. I needn't have worried. It's an excellent product, easy to apply, soaks in well, with a good depth of colour, and well-priced compared to other brands. Will definitely use again.

Long lasting and easy to apply
This order is in preparation for re-treating a shed and summer house. These were both treated with the product by the manufacturer and have been re-treated once since. The product is easy to apply, covers well and gives a long lasting finish.

Very prompt delivery, product does what it says and soaks in well. Just hope it lasts!
Terry Abbott

Initially I was dubious but once I had used it all was fine.
I hate painting and at first this product, being like water, was difficult to control on the brush. However it certainly soaked into the wood and did what it said it would do.

Very easy to use and is absorbed well into the fence timber.
Very easy to use and is easily absorbed into the fence timber. An excellent product that gives me great confidence that it will do what the company says it will do.
