Before applying Barrettine Mould and Mildew Cleaner, remove as much surface dirt, debris and organic growth as possible with a scraper, stiff brush or broom.

Always do a small test area before starting any project and follow the manufacturer's instructions on the container at all times.

For maximum biological effectiveness it is recommended that Barrettine Mould & Mildew Cleaner is applied to dry surfaces.

This product can be applied by brush, roller or re-used kitchen spray bottle at a rate of 5 to 10 meters square per litre, depending on how porous the surface to be treated is.

Only use Barrettine Mould and Mildew Cleaner when the surface and ambient air temperature is above 5℃.

  1. Apply by brush, roller or spray
  2. Scrub the treated areas and leave to dry for 20 minutes
  3. When dry, rinse off all substance
  4. Repeat if necessary (2nd application not normally required)
  5. The wood is now ready for finishing

To maximise biocidal effect, follow same instructions as above, however leave for 24 hours to dry before washing off.

Once the wood has been treated and cleaned with Barrettine Mould and Mildew Cleaner it is ready to be treated with a wood preserver to protect against future infestations and finished with an appropriate wood oil,, wood paint or other wood finish.

Did the job by P J King

Needed to clear green growth on pergola prior to retreating. Scraped surface down with steel wool, applied cleaner, left it for day, the dead material turned white but it didn't bother me because I followed up with dark stained treatment. ps I spilled a bit on some moss below and it turned that white too so take care to protect your plants.

Easy to apply and cleans up well by J Kane

Used this to clean up my garden sleepers before staining them. It worked a treat. Easy to apply and would recommend it to anyone. Not much more to say. I will say that the wood-finishes team were a great help, had great prices and fast delivery.

Cleaned up very mouldy decking by Mihai Cucos

Needed to clean some very dirty decking - it was absolutely caked in thick black mould and hadn't been touched for about 10 years. Used the more concentrated dose of the product and left it on for about 20 hours. Bit of elbow grease and water and the decking is good as new. Can't ask for more really.

Easy to use by Tim Ellis

This product worked really well. I was using it on an old railway sleeper that has been left outside for 100 odd years. It cleaned it up really well after two applications

Thin consistency but did the job by John Roberts

Difficult to apply without splashing it but it did seem to be absorbed by the wood - time will tell how effective it is as a preservative
