Product Details

Keep your interior and exterior walls looking good using this Barrettine mould and mildew cleaner. The ready-to-use surface biocide controls the growth of algae, fungus, mould and mildew. It can be used on most materials including timber, concrete, brick, plaster, stone and tiles.

The cleaner can be applied using a brush, roller or spray, which makes it suitable for application on a wide range of surfaces. Before any subsequent treatment, make sure you allow it to dry completely for the biocide to have maximum effect. You can repeat the process in heavily contaminated areas. One litre of cleaner covers 5-10m², so this 4L container is sufficient for treating a large garden shed or garage.

Barrettine Mould & Mildew Cleaner 4L is rated 4.4 out of 5 by 71.
Rated 3 out of 5 by from It works, but not well enough for our shed. It’s ok, but its effectiveness probably depends on how bad the mould is. Our shed (smooth shiplap) still has dark patches after two applications.

Rated 4 out of 5 by from Good clean up. Certainly cleaned up out side on wooden chairs etc.

Rated 3 out of 5 by from Worked well on lightly algae covered fence panels I did as instructed, brushing off the green algae from my fence panels prior to application, left it 24 hours then brushed it off again and rinsed off with water. The areas which were only lightly affected initially came up really clean but the heavily algae covered panels were still quite green so I will have to try another application

Rated 5 out of 5 by from Mould AND mildew remover. Yes. AND. I misread the label and thought this product removed mould OR mildew, but in fact it will remove mould AND mildew. Extraordinary. It means I don’t need to take 2 bottles into the garden. I can just clean. And go.

Rated 5 out of 5 by from Easy to use Used this product to kill mildew and mould underneath a caravan. Easy to apply with sprayer. Left it to work overnight and wiped off with damp cloth the next day. Surface looked as good as new.

Rated 5 out of 5 by from Amazingly Effective This is undoubtedly the best I have ever used. I put it on a fence and some concrete benches with a spray. The following morning there was no trace of moss. The product cannot be bettered. A serious downside was the handling of it before delivery to me. Two of the three containers were punctured from obvious physical abuse before it was packed and delivered to me - one even produced a mini fountain when I removed the top. Not only was my surroundings seriously contaminated with the moss killer, so was I and I am not sure what health issues that might generate in the future. Sadly Toolstation has not yet found the energy to respond to my complaint!
