Gap Sand

Gap Sand is a special blend of graded fine sands and additives designed to lock into place all types of brick and block paving.
 

PLEASE NOTE Gap Sand is suitable for filling joints up to 3mm maximum. It is not designed to function as a grout.  Finished Gap Sand will be firm, but not hard.  For larger joints, Cement Australia Sand & Cement is recommended.

Applications
Paver Jointfill

Paver Jointfill

  • Forms a workable yet stable joint between pavers, up to 3mm gap
  • Inhibits weed & insect infestation
  • Minimises paver distortion
  • Covers approx 3.5mfor brick shaped pavers; 122 for 400mm square pavers, 50mm depth 

Lay pavers as per manufacturer’s instructions. Sweep Gap Sand into all joints using a stiff broom, until all gaps are filled.

Work a vibrating compactor, rubber mallet or similar piece of equipment over the entire paved area to assist the flow of filler into the joints and to ensure the joints are firm.

Thoroughly sweep the paved surface, topping up where necessary and remove all excess surface sand.

Mist spray the paved surface ensuring that all areas receive a thorough wetting. Avoid heavy spraying or flooding of areas. When Gap Sand is dry and firm, paving is ready for traffic

 

Allow 3 days for the Gap Sand to bond the pavers into place before using the paved area.

Brick shaped pavers:     One 20kg bag covers approximately 3.5 m2 at a 3mm gap 

400mm Square pavers:  One 20kg bag covers approximately 12m2 at a 3mm gap 

  • Gap Sand is not a cement based product and therefore does not stay permanently firm like mortar.
  • When Gap Sand is wet from either hosing or rain, or from dampness raising from the sub base, it is soft and pliable and reacts like wet sand, albeit a little ‘stickier’
  • Only when it is completely dry does Gap Sand form a firm bond between the pavers
  • Care should be taken whenever paving is hosed not to point the water stream directly into the gaps as this will dislodge wet sand
  • Gap Sand is not recommended for use in paving where the gaps are greater than 3mm wide. Cement Australia’s Sand & Cement, swept in dry or mixed wet, is recommended for paving with gaps wider than 3mm
  • Gap Sand is not recommended for areas where pavers are subject to continual exposure to moisture - EG: pavers around the pool

  • Gap Sand should be stored in a dry place, off the ground and be protected from ingression of moisture
  • The recommended shelf life is approximately 6 months from date of manufacture. This is provided the product is stored as recommended above. Once opened, the bag must be used on that day
