Barrettine Premier Wood Preservative is an all-in-one, spirit-based wood preserver for the treatment and prevention of dry rot, fungi, mould and protection against woodworm.

Ideal for smooth or rough exterior timber including fences, sheds, decking and more.Quick and easy to apply with a brush or roller. Harmless to plants and animals when dry.

Can be overcoated with Barrettine Log Cabin Treatment or Decking Oil for additional protection.

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.

Barrettine Premier Wood Preservative contains a small amount of wax (Less than 1.5%). Water Based products or paints should not be used on top of this product as the wax content will likely repel the water based product, preventing it from bonding with or penetrating into the timber.

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.

Wood Preservative Colours

Please Note The colour swatches shown above are for guidance only as the final colour is dependent on the type and age of the timber being treated. The initial colour tends to be stronger and brighter when first applied but will 'tone down' over time as the surface of the timber is subjected to weathering.

Exterior wood to be treated must be clean, dry and free from surface coatings such as varnish or paint etc. Any such coatings must be fully removed by sanding or with a suitable remover before applying the wood preserver.

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.

Application brushes should be cleaned immediately after use with Barrettine Brush Cleaner or white spirit and before the product has had chance to dry. Dirty brush cleaning solution should be disposed of properly and not poured down sinks or into drains.

This solvent-based wood preserver should only be used in well ventilated areas. Care should be taken with the cleaning and disposal of any brushes, cloths, tins or other materials that have come into contact with this wood preservative.

  • Wear suitable protective clothing and suitable gloves. Wash any contamination from eyes or skin immediately.
  • Do not contaminate foodstuffs, eating utensils or food contact surfaces.
  • Thoroughly wash hands and any exposed skin after use and before meals.
  • Ensure that all water storage tanks are thoroughly covered before application.
  • Remove, cover or protect all fish tanks / ponds before application - Harmful to aquatic organisms.
  • Keep product in original container only.
  • Keep container sealed and in a safe place at all times.
  • Keep out of reach of children at all times.
  • Do not breathe fumes / spray.
  • Ventilate treated areas thoroughly after application.
  • Keep away from sources of ignition - NO SMOKING.
  • Until dry - Treated surfaces can pose a fire risk.
  • Not suitable for use on garden furniture unless over-coated with an appropriate sealer i.e exterior wood oil or varnish.
  • Do not empty contents in to a drain or soil.
  • Avoid contact with all plant life.
  • Hazardous to Bees.

If swallowed, do not induce vomiting, seek immediate medical attention and show the product container / label.

Avoid contact with plastics, masonry and other non-wooden surfaces. Spillages on bitumen type products may soften or swell with the fluid or vapour.

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.

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

The best by Duncan P.

Soaks deep into the wood, two coats required. The product has a high VOC so really smells (use outdoors only) and protective clothing - eye protection, gloves - really advised. Treated a new fence with this and interior of shed - after which no spiders inhabited. Highly effective, and 5L goes a long way. On my third can now, great product.

Streaks above water based preservers by BRIAN TICKNER

I have this product for a few years now and our Summer House is still looking as new after five years of annual treatment. You can see the preserver penetrate the grain of the timber and once dry it has a natural look unlike some of the water based products which can look terrible and flake off with time. It is easy to apply but do take care to protect things you do not want treated (including yourself ) as it stains most things and can make your skin irritated.

Very good, highly recommended by Neil Thomson

Have put three coats of this on my log-built garage and have never had an issue with it. Goes on well - watch out for splashing, as it is quite a thin liquid, and you get good coverage from it. Water just beads on on it. Been on for two years now, with a coat of Barrettine's Log Cabin Treatment over it, and I have no complaints. Still looking good!

I cannot fault this product by Mr R BROAD

I use this on my very large fence every year for the last eight years and the timber is as good and new looking as the day it was erected. It penetrates instantly keeping the natural look of the timber while waterproofing and prolonging the life as well as getting rid of any bug that tries to make a home in the wood. I strongly recommend the use of this product.

A quality product that has secured a reasonable future for a range of garden furniture by Tom Davies

Buying this product a couple of years ago I was impressed by its immediate absorption into very dry timber. As a consequence the old garden furniture has been restored and its life extended. recently I have bought more for sheds and fences. I have tried many in the past and this has compared most favourably against the rest.

Bought for a new shed. Gives a rich deep colour. Better looking than water based wood paints as this leaves the grain shoring through. Gives good water repellent finish

It does what it says on the tin, and more! by Trevor Walker

The wood preservative colour is probably as close to Red cedar as you can possibly get. Its easy to apply and dries quickly giving immediate protection and deep colour to the surface applied to.

Excellent product with very good coverage by John Connor

Had to paint about 13 six foot fence panels one side 2 coats. Purchased 4 tins of Barrettine preserve to do the job. Used summer tan which looks horrible on the tin but in real life looks nice ( mid brown ). Down the years used lots of different products but this has to be one of the best. Beats water-based fence paint for longevity and coverage. would recommend this product for all rough sawn exterior timber.
