Preparation

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. For maximum biological effectiveness, it is recommended that this product is applied to dry surfaces.

Application

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

Barrettine Mould & Mildew Cleaner can be applied with a natural bristle brush. It can also be applied with a trigger spray bottle such as a re-used kitchen spray bottle. Any recycled bottle should be thoroughly cleaned before use. Apply at a rate of 5 to 10 meters square per litre, depending on how porous the surface to be treated is. Only use when the surface and ambient air temperature is above 5°C.

Apply using your chosen method
Scrub the treated areas and leave to dry for 20 minutes (or to maximise biocidal effect, leave for 24 hours to dry before washing off)
When dry, rinse off all substance
Repeat if necessary (although a second application is not normally required)
The wood is now ready for finishing

Finishing

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 then finished with an appropriate wood oil, paint or wood stain.

Danish wood oil

I think it’s fantastic probably the best wood oil in the world, very easy to apply flows off the brush brings out the wonderful grain of the wood, and the finish is extremely hard . Just perfect thank you. DC .

Effectively removed green algae, grey surface mould and grime from a garden lodge

I used it to prepare for painting a red western cedar garden lodge Danish oiled ten years ago. It removed low level green algae and a thin grey mould covering several areas. I divided the horizontally cladding into one metre vertical columns working from the top applying the product to three planks and vigorously stiff brushing before immediately repeating. As I worked downwards I could see I was removing a lot of surface grime but 24 hours later after throughly dowsing it with a garden hose at shower setting (to avoid creating an aerosol) and brushing once more I was amazed by how clean and refreshed the surface looked. I used a waterproof hooded overall, full face protection and rubber boots. The product was certainly low VOC.
