Surprised at how good this was!

I had cleaned my Indian Sandstone patio using the Sodium Hypochlorite - the only way to restore it. Some stubborn black spot marks left so treated afterwards with this and over the course of 2-3 weeks more of the black spot seemed to almost dissolve. Very pleased with the result so I have bought some more! Beware - the Sodium Hypochlorite is aggressive and did dissolve my pointing but I am still happy as I now have a bright coloured patio again. I will use the Black Spot Preventer to try and keep under control. Wish I had taken a "before" pic as my patio was dark grey and no colour prior to treatment. Thanks also to Chloe - great service.

it has to be frequently re-applied

I di not research the product well enough, because I did not realise that it had to be re-applied every 4 months or so.I hope that two applications a year will be sufficient, but we will have to wait and see. The price and delivery time were good
