Furthermore, this is also a patio algae remover as it will eliminate mould, algae and other similar deposits.

Add more product so the surface is visibly wet, do not allow the product to dry on the surface. Agitate with a brush to move the solution over the high areas of the stone. This will also to stop the fluid from simply sitting in the low areas of the paving.

A single long dwell time is more effective than repeating the process on multiple occasions with shorter dwell times.
