ProMasonry Polymeric Sand is a blend of water-stable polymers with precisely graded aggregates that cures into a durable and resilient material.

For paver joints in walkways, driveways, patios, terraces and pool decks.

Available in two colors, gray and beige.

  • Helps lock pavers in place.
  • Helps prevent erosion/wear of the joints.
  • Helps prevent joint damage from ants/insects.
  • Helps prevent weed growth in joint areas.
  • Will not support biological growth/mold.

Pavers must be set on a proper drainage bed of stone and sand. Refer to Tech Spec #2 from the Interlocking Concrete Pavement Institute for specifications on draining, compacting and spreading the sub-base and bedding sand.

  • Pavers must be compacted. Refer to Tech Spec #2 from the Interlocking Concrete Pavement Institute for specifications on placing concrete pavers.
  • The paver's surface must be completely dry prior to placing the sand.

Pour the Polymeric Sand consistently across the entire area.

  • Sweep the product into the joints using a hard-bristled broom.
  • Compact with a vibrating plate compactor.
  • Repeat the first two steps as necessary to ensure tightly packed joints.
  • Sweep off all of the excess material using a fine-bristle broom.
  • Blow off any remaining residue using a leaf blower.
  • Inspect the joints; the polymeric sand must be level with the bottom of the paver's chamfer.

Wet the area using a fine mist. Fully saturate the joints but do not let the water pond or run in the joint.

  • Repeat the first step two more times, allowing 10 - 15 minutes between applications.
  • Protect joints from rain for 12 hours to guarantee proper curing.

Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40F for 24 hours.
