Barrettine Premier Wood Preservative

best price guarantee
Read reviews (251)

An all-in-one, spirit-based wood preserver for the treatment and prevention of dry rot, fungi and mould as well as protection against woodworm etc.

Barrettine Premier Wood preservative is ideal for smooth or rough exterior timber including fences, sheds and decking.

Quick and easy to apply with a brush or roller. Harmless to plants and animals when dry.


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.


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

Drying Time

Up to 48 hours drying time, however temperature and humidity will effect duration.

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 oil. Animals should only come into contact with the surface of the wood when both the wood preserver and oil have fully dried.

I made order as a result of former experience.
I am 84 years of age. and have little time or energy to do more than what really needs to be done to the premises. The product does what it is intended to do, but more than this I am most grateful for the courtesy and helpfulness I encounter when dealing with your firm. At my age, this matters! Thank you.

Excellent Product
I have only one concern and that is pouring it out of the can without spilling or drenching the surroundings. All the reviews you read are spot on. It covers like a dream, looks superb and if used in the open air the fumes, which are not long lived, are not an issue. I am just about to order some more and have recommended the product to family and friends so I think a bulk purchase will be on the cards.

Excellent service, excellent product
Easy to use either by brush or spray gun. Coverage brilliant! One of the best, if not the best wood treatment products I have bought. I intend to purchase another tin within the next few days. Staff very helpful and delivery excellent. Thank you.

 Summer Tan
Great Product - recommended by my Summerhouse supplier
The product is a great to work with and is soaked in by the wood where required. Pouring out the preservative from the 5 Litre tin is impossible without spillage. The mouth of the tin needs to be redesigned to help ease pouring out the liquid. Otherwise, a great product.

 Summer Tan
A high quality product
This preservative is easy to apply and the slight odour disappears quite quickly. The colour is good and spread is even. Two coats are best where there is strong sunlight.

Easy to apply, lovely colour for the garden.
Excellent product and superb customer service. I knew where my tin was for almost every second of its delivery to me!! The stain seemed much thinner than I expected, but was easy to apply and covered well. Ignore the warnings about how long it takes to dry!! Touch dry in about 30 minutes and completely dry within an hour. Lovely colour, used on railway sleepers as a base for a greenhouse which is stained in the same colour. Excellent.

Easy to apply (at least my wife said it was!)
Very effective (rain droplets just roll off) and attractive finish (the holly green).

 Golden Brown
Great colour. Easy to use
Really warm brown colour. Applies easily and good coverage. Looking forward to treating the next shed.

Great product
I used a sprayer to treat my fence panels. It was so quick with good coverage and rain just runs off now. Impressed with fast delivery and great product.

Good colouring and covering.
Good colouring and covering properties, but a bit messy to apply. If one is a bit too energetic and enthusiastic it splashes all over you (especially if it is windy). Having said that, it is an excellent product, I have used it for several years now, and I will continue to do so.

Very good coverage
Have used this product before, very good coverage, enhances wood colour & protection and excellent value. Used to refurbish pub garden tables & chairs.

 Golden Brown
Excellent product and easy to use. Good colour range
Have used this product now for over two years on many garden sheds, fences etc. and have always found it to be very good. It is easy to apply, soaks in well and dries fairly quickly. Too early to assess over very long period but so far appears to resist rain OK and is weathering well. Happy to keep re-coating with this product.

 Golden Brown
Infinitely better than any water based product, needs at least 2 coats, covers well, a little goes along way
Spirit based product, goes on very easy and a little goes a very long way. Repels water, needs at least 2 coats, don't bother with any water based product this is the best.
Josie Easom

 Light Brown
Natural, subtle look
I am quite critical when it comes to wood and gardening. This stuff went on really easy, soaked into the wood. The colour was fab- natural looking and not too garish or bright which is just what I wanted. Would defo recommend.
Simon Labrow

Easy to apply, quick to dry
A great preservative when you have large amounts of timber to treat prior to construction. Actually dipped some of the end grain pieces and painted on to sides with piece still in a bucket. It dried quickly as well so could apply second coat same day. I used clear and will then use tinted oil based treatment once building up.
JM Winchester

Excellent coverage and good wood penetration
Easy to apply with excellent coverage. Not an unpleasant smell but I did apply outside. Bought on the strength of other users' comments with regard to effectiveness. Time will tell as to whether I experience similar results.

 Light Brown
Excellent product
Once applied this product holds its colour and enhances the natural appearance of the wood, unlike water based proucts. Take care when applying as it can end up where you done want it to. Having said that, this is, by far, the best wood coating product I have ever used in 40 years of garden maintenance experience.

 Dark Brown
Great wood preservative, much better than water-based.
Soaks in really well and quickly, preserves wood much better than water-based products. Repels water too, which can be seen when it rains. Even though it is solvent-based the smell is not unpleasant or strong.
Brian Fairless

I needed two coats for my very porous timber fence but once on & dried the rain just runs off like water off a ducks back.
Ideal for new timber fences & with a lightly stained oil to finish it I got a lovely golden brown colour, smashing.

Goes on like a dream, good coverage. Even as I was applying the first coat the weather changed, to drizzle and I could see the rain just rolling off.
