What is polymer sand?

Polymer sand is a combination of granular materials that helps lock fine sand particles together, ensuring your pavers won't shift over time. By adding water, polymeric sand becomes an impenetrable joint filler solution that locks your paving units together.

The benefits of polymer sand

  • Helps secure pavers in place
  • Prevents weed and insect damage
  • Prevents erosion due to wind, rain and frost

How to install polymer sand?

Step 1

Spread the FLEXLOCK ULTRA G2 using a stiff bristle broom. Make sure the joints are completely filled with FLEXLOCK ULTRA G2No other material should be in the joints. Leave a layer of FLEXLOCK ULTRA G2 on the surface to obtain better compaction and joint consolidation results from FLEXLOCK ULTRA G2For textured or prefinished paver surfaces, we recommend removing all sand from the surfaces before running the vibratory or roller plate.

2nd step

Using a vibrating plate, slide the FLEXLOCK ULTRA G2 into the paver joints. It is recommended to use a rubber pad. A roller compactor is preferable in the case of slabs. Fill the paver joints up to 3 mm (1/8 in) below the surface of the pavers. It is recommended to compact in alternating directions to prevent air bubbles or voids in joints. Repeat steps 1 and 2 to make sure the joints are well filled and compacted. Filling narrow joints requires more care.

Step 3

Sweep excess FLEXLOCK ULTRA G2 from the paved surface, first with a hard bristle broom, then with a soft bristle broom. Check that the FLEXLOCK ULTRA G2 is 3 mm (1/8 in) below the surface of the pavers or slabs.

Step 4

Water an area of 2.8 m2 (30 sq. ft.) for a minimum of 30 seconds or until water beads up and collects in the joints.
