What is polymeric sand?

Polymeric sand is a combination of granular material that helps lock the fine sand particles together, which ensure that your pavers don’t move over time. By adding water to it, the polymeric sand becomes an impenetrable joint filling solution that locks your paving units.

The benefits of polymeric sand

  • • Helps lock paving units in place

  • • Prevents weeds and damage caused by burrowing insects

  • • Prevents erosion due to wind, rain and freezing

How to install polymeric sand?

Install Flexlock Step 1

Step 1

Spread FLEXLOCK SAND G2 with hard-bristle broom. Make sure the FLEXLOCK SAND G2 completely fills the joints. Do not use other materials in the joints. Leave a layer of FLEXLOCK SAND G2 missing space on the surface to aid in the vibrating and consolidation of FLEXLOCK SAND G2 into joints. For textured or pre-finished surfaces, we recommend to remove all the sand from the paver or slab surface prior to using the plate or roller compacter.

Install Flexlock Step 2

Step 2

Vibrate the FLEXLOCK SAND G2 into the paver joints using a vibratory plate compactor. A rubber pad is recommended. A roller compactor is best for slab installation. Joints should be filled up to 3mm (1/8 in.) below the edge or 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.

Step 3

Sweep off excess FLEXLOCK SAND G2 from the paved surface, first with a hard-bristle broom, then a soft-bristle broom. Take care to leave the height of the polymeric sand at least 3mm (1/8 in.) below the edge or chamfer of the paver.

Shower for a minimum of 30 seconds for 2.8 sq. m. (30 sq. ft.) or until the FLEXLOCK SAND G2 repels the water and the water starts to accumulate on the joints.
