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 Natural Stone will remove ‘Black Spots’ from Indian Sandstone, York Stone, Limestone (including Bath and Portland Stone), Purbeck stone and other Natural Stones. Patio Black Spot Remover will restore the colour back into your stonework that you thought you had lost forever.
 
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!
 
Directions:
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 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 2 hours. 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.

Hello Simon, although I purchased your product in April, mainly due to the weather, I have only just used it...and the results have been spectacular! Many Thanks! Now it is back to its original condition, is it ok for me to seal the Indian Sandstone with something to prevent the reoccurrence? Please advise the possibilities. Thanks again. I hope your business is thriving?! Best regards, John

The effect of the Patio Cleaning is amazing! It had started to look like concrete slabs, due to the amount of "Black Spotting", but the cleaning has restored the beauty and colour of the Indian Sandstone! Thank you for your hard work and effort in giving us back a restored patio that is now a pleasure to use. We would recommend you to others. With Best wishes, Kathy

Slight delay in getting product but it was worth the wait!! I would like to order another 4 litre because a couple of areas need doing again but it is a fantastic product. The patio looks lovely.

I bought some black spot remover for my sandstone patio nearly a year ago, after having researched on how to clear up the horrible black spots. I have only just gotten around to using it and am absolutely amazed with the results - some of the indian sandstone was completely black and it has been restored to its original beautiful colours. I'm going to buy some more now so I can finish the rest of my large patio.

Excellent product. I used it on an Indian stone patio. Within 1 hour of application and long before I used the pressure washer I could actually see it working. After I pressure washed it the patio was back looking as good as the day it was laid.

Our beautiful Indian Sandstone patio had been attacked badly by black spot. I tried all types of cleaners and even bought a new stronger pressure washer but to no avail. The overall appearance had become dull and grey. I was sceptical about Patioblackspot remover given the cost but was desperate. I was frankly amazed by the result. Within minutes of applying it I could see the colour returning. After an hour 90% of the spots had disappeared and the patio looked like new. 1 year on and it sill looks great - just the occasional blast with a pressure washer to get rid of the green algae that builds up and the colour comes right back. I cannot recommend this product highly enough!

I have to admit I was sceptical that the Black Spot Remover would work but, having spoken with James, I took his advice and ordered one bottle to try it out. As soon as I had applied the product to a section of our sandstone patio, I was back on the phone to James ordering the further amount I needed to complete the job. The patio is back to its former glory and I'm delighted. There is very little effort involved in achieving this transformation. The product is expensive BUT it works!!! I have diarised to order the Preventer early next year and hope to be able to confirm that the product has a lasting effect.

'The Black Spot Remover is a remarkable product. Quick and easy to use it far exceeded my expectations. My patio now looks as good as it did the day it was laid ten years ago. You will not find better value for money
