Bests & Worsts Reviews from Amazon

I have a north-side brick patio. When I bought this house it was covered, and man I mean covered with moss. A good power wash each Spring was never enough to stop the moss from returning and month after month during the Summers was a struggle, man vs plant. I did that for two years, cursing and complaining the whole time. This April I did my Spring power wash as usual and immediately treated this patio. It is now going into August and I have not had even a wisp of moss this year - I mean nothing! I would recommend this product without any reservations. When you put it on you may think to yourself that it doesn't look like you really did much. It dries quick and looks the same as it did before, but wow does it do exactly what it says it will do.
