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.

Brilliant product, would recommend to anyone. Brought my 8year old natural stone patio back to life. Could hardly believe my eyes. Very impressed with the result and so glad that I decided to give it a go. Thank-you BSRC

Amazing!! I was sceptical after spending quite a large amount of money on this product for my patio! My Indian sand stone has come back to a colourful life again! Love it. I will be ordering the protector next summer.

An amazing product. I wish we had found it sooner. It does exactly what it says it will. We sprayed our patio one afternoon and pressure washed it the following day. As we sprayed we could literally see it working. It has transformed our Indian sandstone patio - I had been so full of regrets about having it laid as it has looked so bad for so long and not responded to pressure washing - now with the Black Spot Remover it looks brand new again.

After googling the symptoms of our patio and coming up with black spot, I purchased 8 litres of the black spot remover for natural stone. I knew it wouldn't be enough, but as I thought it was quite expensive I wanted to make sure that it worked first. We sent our dog on a sleep over for the night and applied the black spot remover. I couldn't believe the results! In less than one hour all the black spots had been removed. I left it on for as long as the instructions said and then rinsed. The colour of the stone was back to it's original beauty. I was still slightly dubious though that it was in fact just bleach, so before purchasing any more I decided, the next day, to put neat bleach on a couple of the remaining stones just to see if I could treat the rest with that instead. The bleach did nothing, the black spots remained. I have now purchased another 2 bottles to complete the patio. The back spot remover is in fact in my opinion worth every penny - the results were excellent - so much better than I expected by a long way.

This solution works wonders. I was a little sceptical before I used it for the first time but after 2 hours I was amazed by the end result the patio looks as good as new now !

Lynne Watkinson-County Durham-5 Stars

We are delighted with the result of the Patio Black Spot Remover. Our Indian Sandstone patio now looks like it did when we first had it laid over 10 years ago. We would have no hesitation in recommending this product and company to anyone. Thank you so much.

Wow Wow Wow!!! I rarely leave reviews on products purchased but feel absolutely compelled to do so here. I'm sceptical by nature and after speaking directly with Simon at PBSR decided to take the plunge and purchase the black spot remover. One bright Sunday morning with no rain on the horizon I decided todays the day! I loaded the sprayer and tested on 3 heavily infested slabs - within 20 minutes I could start to see the infestation slowly disappearing . It was at this point I jumped in with both feet and treated the rest of the patio. To say I was amazed at the results is an understatement, it looks like new and all the colours of the Indian sandstone, that I had forgotten existed, have returned. I took some pictures before and after to remind myself of just how unloved the area looked prior to treatment. If you're thinking of purchasing but think it's expensive, it is! But it works, your patio will look fantastic and it's a lot cheaper than a new patio. In fact I've just ordered some more for another area and can't wait to see it in all it's new glory.

I was quite sceptical but James suggested I try a small amount first and I was 'blown away' with the immediate transformation of our patio. I immediately called for the remaining quantity I needed to complete the job. Six months later we are still delighted with the outcome and with the full colour that has been restored to the stones (Indian Sandstone). James has been very helpful and I'm about to order the Preventer to keep our patio gleaming. It's expensive but effective.
