Joint-it premium block paving joint filling compound Joint-It Fine is best applied on a newly laid driveway, where there has been no previous weed growth. If applying on an existing driveway, you will need to use a high-power pressure washer to clean out all of the joints to ensure there are no weeds. After this, spray all the joints to ensure no weed plants are left. Then you can apply Joint-It So Fine. Joint-It Fine is a preventative product, but it won’t stop weeds growing that have already planted in the joints before application.
