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

For added protection against mould, algae and wood boring insects, pre treat garden wood with Barrettine Premier Universal Preservative first.

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

  • Remove traces of surface dirt, debris, mould and algae with a stiff brush, broom or scraper
  • Areas that have been affected by mould, algae or fungi should be treated with Barrettine Mould and Mildew Cleaner prior to application

Previously Coated Timber

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

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 a suitable 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.

  1. For unpreserved/untreated timber we recommend using Barrettine Premier Universal Preservative first
  2. Apply with a brush, leaving a minimum of 6 hours between coats

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.

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

Excellent protection whilst leaving a natural friendly finish by Jeff Golding

This is the manufacturer recommended finish for my garden furniture. It provides a non blistering, non peeling finish to raw wood products. Application is simple I use a small brush to do the end grains and then a small cloth covered sponge for the main application. This gives you a fast, even run free finish in a very fast time. I clean up my hands using warm water and washing up liquid. Fast and easy enough to apply yearly.
