Mix equal parts bleach and water into a spray bottle.
Saturate the moss with the bleach mixture and allow it to soak for approximately five minutes.
Pressure wash the cracks between the pavers to remove all of the moss. This will also clean dirt and other debris from the pavers.
Allow the pavers to completely dry.
Spread polymeric sand in the cracks or spaces of the pavers. Spread the sand using a broom so that all of the crack are filled. Tap the sand with the broom to press the sand between the pavers. This will prevent moss from growing between the pavers.
