ABOUT THE PRODUCT

The black spots that grow on your garden stonework are actually spots of black lichen! The spores from the black lichen start life as tiny dust-like spores growing on the underside of leaves on trees and plants.

These spores are carried by the wind and the rain onto your stonework in their millions. Once they have landed the spores have a two-year germination period. So for the first two-years of your patio’s life it will remain looking really clean. In year three the colour in the stone will start to look dull and look like someone flicked ink across your stonework leaving tiny ink splatters. The reason why they grow on your garden stonework is because they feed off the minerals within the stone. Once they have exhausted an area of the stone of all its minerals they grow in search of more. Not only do they spread across the stone giving spot like appearance, they also burrow down into the stone at a rate of 2mm a year.

Encouraged by warm, damp conditions, these unsightly spots will only get worse if left untreated, ruining the original beauty of your garden stonework.

Black spots are incredibly resilient and can’t be removed by pressure washing. So if you’ve tried washing your stonework and the spots remain then there’s your answer. Take a look at the pictures on our site. Look familiar? Black spots it is!

Our Patio Black Spot Remover has been specifically developed to remove black spots. It’s not your standard patio cleaner; it targets patio black spots and restores the natural colour.

You certainly can!  – you can buy it yourself in our online store then apply it easily to your patio.

You must use a 5-7 Litre pneumatic pump sprayer. These are typically £30-£35 from your local garden centre. Apply the product like a fine mist and saturate the area. Any questions after completing the trial slab, give us a call on 01252 702123.

If the stone is dirty with no visible colour, yes you should pressure wash before. For the best results, ensure the product comes into direct contact with the stone and the ‘black spots’. The product is biodegradable, if you apply it to dirt, it will not work.

They will if you use our Patio Black Spot Preventer annually. Using Patio Black Spot Remover followed by a thorough jet washing is enough to remove the spots in the first instance.

Yes. Biodegradable and animal friendly, the Patio Black Spot Remover is not harmful to flowers and plants, and is safe for family pets. Please avoid spraying any neat product directly onto plants and the grass. In diluted form, it will not cause any harm.

Please be careful when using the product close to fish ponds. You must avoid all the run off from entering the pond as it would harm any aquatic life. If a small amount of the product enters the pond it would not cause any issues.

We recommend pressure washing first, this way you remove most of the surface dirt which is usually what requires the most amount of water. Once dry, apply the product and lightly wash off afterwards, this way there is less contaminated run off. We recommend using sandbags to stop the flow of water. We have carried out several applications around fish ponds like this with no issues. 

You wouldn’t need to use the Remover every year. Only for the initial treatment. The Preventer which you apply 12 months later is a spray and leave treatment so wouldn’t cause any issues with the pond.

Patio Black Spot Remover is unlike any other product on the current market as it is the only product that can remove black spots from your garden stonework with almost instant results. It will not only remove the black spots but ALSO remove white fungi spots and restores your stonework, giving it that ‘just been laid’ look. PBSR has been on the market for over 10 years. Not once have we met a patio we're unable to remove the spots from. We use our products every day and know how to get the best results.

NO! Never apply Patio Black Spot Remover when the day temperature is below 5°C and never use if the temperature is likely to dip below freezing overnight. The surface MUST be dry or the product will not work.
