Barrettine Wood Protective Treatment is perfect for most exterior timber structures such as Sheds, Fences, Trellises, Pergolas and Timber Gazebos.

Ensure that surfaces to be treated are clean, dry and free from surface dirt, debris, mould, algae and other surface contaminates.

New or Bare Timber

Previously Coated Timber

  • Any previous surface coatings such as paint, varnish or stain must be fully removed and sanded back to bare wood, unless it's a wood preservative treatment

Old Timber

  • 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 biological growth
  • Areas affected by mould, algae or fungi should be cleaned with a stiff brush or scraper then treated with Barrettine Mould and Mildew Cleaner

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.

Please Note: Wood should be dry for 24 hours before application and rain should not be forecasted for at least 48 hours after application to achieve maximum benefit. Barrettine Wood Protective Treatment is best applied in temperatures between 5℃ - 25℃, Do not apply below 5℃ or in direct sunlight.

  1. Apply Barrettine Wood Treatment evenly with a brush, in the direction of the wood grain
  2. Leave a minimum of 6 hours drying time between coats, longer with smoother wood or with less favourable drying conditions
  3. Apply 2-3 coats for optimum protection

Easy to apply and rich colour after two coats on new tanalised fence panels by John Evrall

Have used Barrettine previously on a summer house with good experience of colour, coverage and its protective properties over circa 8 years. The only niggle is the difficulty of pouring the product without dripping from a full tin.

Great product by Carl Leach

Have been looking for an easy to use product for years and now I have found it. Product is very easy to use. Brushes are very easy to clean. You don't have to be exact with this. Service was brilliant and it arrived quicker than I was advised. YES I will be buying more of this and buying it from this company. Thank you.

Nice finish, easy to use by Clarke Dalby

I made some large barn doors, smooth planed timber. This product stained the doors really nicely without completely 'blacking out' or obscuring the grain. Two coats looked better than three as you could still see a lot of the grain but I didn't want any less than three coats so sacrificed cosmetics a little for durability. Excellent finish and easy to use although you still have to be careful when staining to avoid 'double coating' areas and making them darker than the rest. Protection-wise, we will have to see how it performs but water beads off nicely so am quietly confident.

Easy to apply and unlike reports of some other products, unaffected by rain once dry by David Eccleshall

Product was applied by brush and looked a bit wishy washy after the first application. Left to dry for 24 hours a second coat was applied and the green colour was much better. There is enough product left for a third coat to this 9 ft x 6 ft shed once I can make the time. Good product goes a long way and can thoroughly recommend to other users

See the review below by John Irving

Extremely easy to apply. I used a brush to avoid waste. The colour was everything I expected and gave a 2.4m square workshop two coats all round with the two walls that bear the brunt of the weather getting a third coat. All this was done with two 5litre cans and there's enough left to give a third coat to at least one more wall. Cleaning up was very easy using white spirit. After recent rain the water has beaded off very quickly. I'd definitely recommend it. Even discovered a way of getting into tight cracks the brush doesn't quite touch. Get a small garden bug spray, choke the nozzle down to a fine jet and fire it into the crack. Works a treat.

Top class protection for your wood by Barry Morss

I continue to use this treatment on my outside timber, as nothing else matches its performance. Having built up several coats on my smart new timber workshop, water "beads" on the surface of the wood without penetrating, giving maximum protection.

Good product at a reasonable price by Andrew Lorimer

Used on a fence where we wanted to keep the original wood colour. Applied using a Manns fence / shed sprayer. I had expected to take all day with a brush - finished in a couple of hours with the sprayer. End result looking good.

Very easy to apply -- excellent coverage -- lasting effect -- good value by Brian Coe

a good choice of shades -- very easy to apply by brush -- soaks into wood to give a very pleasing natural look that lasts and protects. Water forms droplets on surface and just runs off. Shelf life no problem for annual use
