In this project, we pressure washed and detailed the whole ground of the house removing all moss in between the pavers without removing sand. We first applied our ground washing detergent and let dwell for 15 min. It treats and kill any organic growth and will make the ground cleaner for longer. After the dwell time, we washed the whole area with the surface cleaner/pressure washing machine and then rinsed to see the results. Since the surface cleaner does not remove moss from pavers, we had to move to step 3 that was using a special tip to remove all moss left. It’s a very time consuming process but the results are great. We rinsed the whole area again and made sure nothing was left behind. Great work and happy customer.
