PRODUCT INFORMATION
Patio Black Spot Preventer will prevent patio black spot infestation on new terraces and pathways. When used annually, Patio Black Spot Preventer will also prevent re-infestation of black spots after they have been removed with our Patio Black Spot Remover.

Patio Black Spot Preventer will also kill green and red algae that grow on garden paths, patios and other decorative stonework.
