  • 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.

 Summer Tan
Great product. Quick and easy to apply and looks great.
Great product! Very liquidy, soaked into the shed immediately. Easy to apply - brush is best - roller creates lots of splatter. Give a good colour and s great finish. Painted 2 sheds from start to finish in less than 2 hours. Would recommend.

 Cedar Red
Excellent Cover and preserver
I have bought the red Cedar and the Dark Brown to renovate a 36 foot "shed" that is in my Son's new garden. The shed has not had much in the way of preserver or stain for a number of years. The shiplap wood panels soaked up the barrettine preserver very quickly, the colour has been restored and with the latest batch of rain I can see that the rain is now beading of the wood rather than soaking in, so hopefully we are getting much better weather protection.

 Summer Tan
Used for a number of years - excellent results on untreated timber
My preference is Summer Tan option for garden fences and summer house - good long lasting colour retention , water repelling and application every three years.

 Holly Green
A great product .. It can't be beaten on price or quality
This is the best product to use for wood treatment Barr none.. solvent based preserver beats anything on the market everytime .I have used this product under different brands names for 40years So cheap I bought 5 tins The only thing I can say is the Holly Green is quite a strong colour more like aquamarine. So if you are just touching up part of a fence etc, be prepared to paint it all or it will stand out like a sore thumb Buy It

Great product and service from Wood Finishes Direct.
As always, Barrettine products are expensive but superior to others and the service from Wood Finishes Direct is superb - easy online ordering and order today, get it next day and the cheapest I have seen for Barrettine's products. Barrettine's products also seem to go further than they say on the tin.
