Vibrate the GATOR MAXX G2 into the paver joints using a vibratory plate compactor. A rubber pad is recommended. A roller compactor is best for slab installation. Joints sand level, must be at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer. It is best to compact in several directions to ensure there are no air gaps or voids in the joints. Repeat steps 1 and 2 to ensure joints are filled and consolidated. Narrow joints require more care to completely fill. After initial compaction, about 30-50% of the sand will drop. Properly compacting will ensure enough product gets filled into the joints. Never skip this step!
