Barrettine Premier Wood Preserver is ideal for most exterior wood care projects including sheds, fences, exterior windows and frames, doors, carports, shutters, wooden garden gates and more. This product can be used as a standalone treatment or as a base-coat for a protective exterior wood oil or decking oil.

Please Note: Barrettine Premier Wood Preservative contains a small amount of wax so is therefore not compatible for use with water based paints, varnishes and stains. If looking to paint, stain or seal exterior wood with a water based product, ensure that the wood is treated with a wood preservative that is oil, wax and silicon free such as Barrettine Premier Universal Preservative.

Ensure that wooden surfaces to be treated with Barrettine Wood Preserver are clean, dry and free from surface dirt, debris and other surface contaminates.

New Bare Wood

  • If required, new bare timber can be cleaned and de-greased with white spirit prior to application of wood preserver

Previously Treated Wood

  • Any surface coatings such as paints, varnishes and stains must be fully removed back to clean, bare wood by sanding or using a suitable stripper / remover
  • Wood that has been oiled in the last year should be allowed to weather for at least one year or until the wood preservative is able to penetrate through to the timber

Old Untreated Wood

  • Wood that has become decayed should be removed and replaced
  • Cut out and burn all decayed wood at least 45cm beyond the area of damage
  • Brush down the wood with a stiff broom or brush to remove any ingrained surface dirt and debris
  • Traces of mould, algae or fungi must be removed with a stiff brush or scraper
  • Areas that have been affected by mould, algae or fungi should be treated with fungicidal wash or mould & mildew cleaner prior to application of Barrettine Wood Preservative

Always do a test area before starting any project and follow the manufacturer's instructions on the tin at all times. Shake or stir well prior to and during application to ensure a consistent colour.

  1. Only apply in temperatures of between 10℃ and 30℃
  2. Apply wood preserver using a synthetic brush, roller or shed & fence spray system*
  3. For the best protection apply a minimum of 2 coats to rough / sawn and smooth timber
  4. Where possible, end grain should be dipped or given extra coats for additional protection
  5. Allow 12 hours drying time between coats

* Although the solvent content of this product can perish the washers and hoses of some spray systems, it can still be a time and cost effective way to treat large areas. We recommend that if using a spray system try to complete the project in one day. This said however, depending on the type and brand of sprayer, it may last longer than this.

Once dry and if desired, a suitable exterior wood oil can be applied. Always follow the manufaturer's instructions on the tin.

Wood treated with Barrettine Premier Wood Preserver can be easily maintained by applying a fresh maintenance coat on a yearly or 2 yearly basis as required.

Please Note: If this product is over-coated with a clear decking oil or other exterior wood oil, it will last for up to 5 years. This is only if the exterior wood oil or decking oil finish is re-applied and maintained on a regular basis as per the guidance on the relevant product.

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 Clear Barrettine 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.

Excellent! by Blair Templeton

This product is the best and the service from wood finishes direct brilliant. Good old fashioned care for the customer which is sadly missing from too many companies these days.

I am very happy with the product and the super fast delivery by J. F.

I have been using Barrettine wood preservative for many years now and though there are plenty of similar products on the market, I have so far been extremely happy with the wood protection I get with the Barrettine Premier Wood Preservative. Whenever building anything from untreated wood, for exterior use, I make sure I give it 2-3 good coats of this stuff and I usually get at least 5 years before re-coating is required. I also use it on pressure treated wood to seal up any areas exposed after sawing to length etc. and it works a treat for this application as well.

Great stuff by Nick The Shed

Easy to use, soaks in to planed timber really well and coverage pretty much as it said on the website. 2 coats of 'Clear' colour has only very, very slightly changed the shade of the new timber that I treated - so a good result.

Cannot say if it will fight off insect attack or rot until a few years have passed. It goes on well without unpleasant smell or fumes. Appears to soak in well and second coat glides on nicely, again only time will tell if it does what it says on the tin!
