PRODUCT INFORMATION
Patio Black Spot Remover is currently the only product developed specifically to remove those hideous black spots and restore the natural stonework. Patio Black Spot Remover for Natural Stone will remove black spots from Indian Sandstone, York Stone, Limestone (including Bath and Portland), Purbeck and other natural stones. Coverage rate is based on a patio that is 3 years old. The older the stone, the more treatments required. Carry out a trial slab to determine the coverage on your stonework.
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!

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

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.

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!

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.

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 its original beauty… 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.

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.
