Patio Black Spot Remover is currently the only product developed specifically to remove those hideous ‘Black Spots’ and restore the natural colour your garden stonework. Patio Black Spot Remover for Artificial Stone will remove ‘Black Spots’ from garden ornaments and all pre cast patio slabs including Marshalls, Bradstone, Haddonstone and other cementatious based slabs.
To maintain your garden stonework and stop the ‘return of the Black Spots’, buy and apply our Patio Black Spot Preventer annually. This will kill any ‘Black Spot’ spores before they have the chance to germinate and turn into spots and will also remove green algae without the need to power wash!
Prior to use, pre wash the affected area to remove any loose debris ensuring the Patio Black Spot Remover can come into direct contact with the Black Spots and stone’s surface. Apply on a cool day, if it dries too quickly the performance will be reduced, on a hot day apply in the evening and allow to dwell overnight. Only apply when the surface is dry, do not apply when threat of rain is imminent.
1/ Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. Pressurize the sprayer.
2/ Using a fine mist spray apply a flood coat, working in sweeping strokes across the stonework. Immediately after apply a second continuous pass at right angles to the first to ensure complete coverage.
3/ DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 4.5 SQUARE METRES PER LITRE. Exceeding the recommended coverage rate will reduce the performance of this product. Coverage will vary depending on surface porosity and profile, e.g when treating sloping areas or riven surface, beware of surface run off and retreat as necessary to ensure correct coverage.
4/ Allow to cure for a minimum period of 90 minutes. In cases of severe infestation or when treating very porous stone allow the product to dwell overnight.
5/ Remove using a pressure washer ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment approximately 50mm from the surface. Adjust this distance to suit your application.
6/ Retreat if necessary to remove any remaining Black Spots or ‘Ghosting’. You must allow the surface to dry before retreating.
The Patio Black Spot Remover is quickly and readily biodegradable. The effluent if washed into soil, flower beds or lawn will breakdown rapidly. This product will not affect surrounding lawns or foliage in diluted state. Keep animals and unprotected persons off the treated area until dry.
Ensure this product does not come into contact with fabrics or furnishings.

Julie Hemsworth-Hull, East Yorkshire-
Was very sceptical and hesitated to buy this expensive product but all else had failed and the only remaining solution was a new patio as over the past two years the black spot had become worse and unable to be removed by power washing. We did this as a DIY project and although it had to be power washed well before and after treatment I was delighted with the result. As the sun was drying the patio it became clear that this product really does work!

I purchased the Patio Black Spot Remover for artificial stone and was totally satisfied with the results. I'm in the process of buying some more for the drive.
Very pleased with this product and the excellent service and useful tips received from Simon. My patio now looks as good as new where previous attempts at pressure washing alone couldn't shift the spots. Highly recommended.
I don't know what is in that stuff but just to say it does work. Our garden is looking great again
