IMPORTANT INSTALLATION NOTES

  1. Always refer to the latest FLEXLOCK ULTRA SAND G2 Technical Data Sheet (TDS) at Flex-lock.com before installing FLEXLOCK ULTRA SAND G2.
  2. Pavers and slabs must be installed according to ICPI Tech Spec #2 traditional base (www.icpi.org) before FLEXLOCK ULTRA G2 installation. For overlay, ICPI recommends 2″ (5 cm) diameter drainage holes spaced approximately 10 ft (3 m) apart and at the lowest elevations in the slab. Holes should be filled with 3/8″ (9 mm) stone and covered with a 1 ft x 1 ft (30 cm x 30 cm) patch of Gator Fabric GF4.4. Drilled holes should allow any water entering the bedding layer to freely flow out.
  3. Pavers’ sides and top surfaces must be completely dry. Do not apply if the paver surface is damp or wet. The damp or wet surface will cause FLEXLOCK ULTRA SAND G2 to prematurely activate and will lead to the polymers sticking on the paver surface.
  4. Do not apply if the paver joints are damp or wet. This will prevent the FLEXLOCK ULTRA SAND G2 from properly sliding into the joints and obtaining very densely packed joints, which is critical to the product’s performance.
  5. Temperature must be above 32°F (0°C) with dry conditions and a minimum of 15 minutes of dry weather required after activation in traditional application and 24 hours in overlay applications.
  6. For all paver surfaces, and particularly around in-ground pools, there must be a minimum slope of 1/8″ (3 mm) per linear foot (30 cm) away from the edge of the pool or structures to ensure optimal performance of the FLEXLOCK ULTRA SAND G2.
  7. For the pool coping units, it is mandatory to use mortar in the joints. For the rest of the paver installation around the pool, you can use FLEXLOCK ULTRA SAND G2.
  8. Do not sweep FLEXLOCK ULTRA SAND G2 over asphalt.
  9. FLEXLOCK ULTRA SAND G2 level, must be at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer or erosion may occur. The filled and cured polymeric sand joints should never be in direct contact with foot traffic or tire.
  10. 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 compactor.

PLEASE NOTE:

All pavers must be completely interlocked for vehicular and pedestrian use. If pavers are fanned they are not considered interlocked. FLEXLOCK ULTRA SAND G2 can be applied when pavers are installed directly open graded aggregates that lock or choke themselves. This means the polymeric sand will not migrate through the voids. Do not apply FLEXLOCK ULTRA SAND G2 when the pavers are installed directly on aggregates with large voids.

  • Adding a layer of bedding sand (C-33 sand or ASTM No. 9) maximum of 1″ (25 mm) on top of Gator Base is also an accepted method, when paver or stone are not equal in height
  • For pedestrian applications only
C-33 sand or ASTM No. 9 stone can be used under pavers.

3 • Overlay application:

  • A minimum 2% top surface slope for proper water runoff
  • FLEXLOCK ULTRA SAND G2 level, must be at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer
  • Minimum joint width 1/8″ (3 mm), Maximum 2″ (5 cm)
  • Minimum depth of joint 1 1/2″ (38 mm)
  • Layer of bedding sand maximum of 1″ (25 mm)
  • Layer of 4″ (10 cm) thickness of concrete with 2″ (5 cm) drainage hole every 10′ (3 m) filled with 3/8″ (9 mm) clean stone and cover with a geotextile for water evacuation
  • For light traffic applications the pavers must be completely interlocked

Note:

  • Remove all loose and fragile concrete
  • Cover the surface with a geotextile Gator Fabric GF4.4, refill with crushed stone and compact it
C-33 sand or ASTM No. 9 stone can be used under pavers.

4 • Overlay application:

  • A minimum 2% top surface slope for proper water runoff

  • Minimum joint width 1/8” (3 mm), Maximum 2″ (5 cm)
  • Minimum depth of joint 1-1/2″ (38 mm)
    Layer of bedding sand maximum of 1″ (25 mm)
  • Minimum layer of 2″ (5 cm) thickness of 0-3/4″ (0-20 mm) compacted crushed stone
  • Layer of 4″ (10 cm) thickness of concrete with 2″ (5 cm) drainage hole every 10′ (3 m) filled with 3/8″ (9 mm) clean stone and cover with a geotextile for water evacuation

Installation Instructions

(For a new paver surface)

STEP 1

Sweep FLEXLOCK ULTRA SAND G2 with hard-bristle broom. Make sure the FLEXLOCK ULTRA SAND G2 completely fills the joints. Do not use with other materials in the joints. Leave a layer of FLEXLOCK ULTRA SAND G2 on the surface to aid in the vibrating and consolidation of FLEXLOCK ULTRA 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 compactor.
Polymeric Sand Installation Step 1

STEP 2

Vibrate the FLEXLOCK ULTRA 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 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!
Polymeric Sand Installation Step 2

STEP 3

Sweep off excess FLEXLOCK ULTRA SAND G2 from the paved surface, first with a hard-bristle broom, then a soft-bristle broom. Take care to leave the height of FLEXLOCK ULTRA SAND G2 at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer.
Polymeric Sand Installation Step 3

IMPORTANT 30-30 WATER ACTIVATION NOTES FOR FLEXLOCK ULTRA SAND G2

  1. Use a watering gun connected to a hose. Set to shower. Watering must be started at the lowest point of the paved surface.
  2. Never allow paved surface to dry out during the water-activation phase.
  3. Do not allow FLEXLOCK ULTRA SAND G2 to wash out of joint.
  4. Shower for a minimum of 30 seconds for 30 sq. ft. (3 sq. m.) or until the FLEXLOCK ULTRA SAND G2 repels the water and the water starts to accumulate on the joints

STEP 4

Shower for a minimum of 30 seconds for 30 sq. ft. (3 sq. m.) or until the FLEXLOCK ULTRA SAND G2 repels the water and the water starts to accumulate on the joints.

INSTALLATION INSTRUCTIONS

(For a existing paver surface)

Remove existing jointing material. Be careful not to disturb the bedding material under the pavers. Pavers must be completely dry before installing a minimum of 1 1/2″ (38 mm) deep into the joints. FLEXLOCK ULTRA SAND G2 level, must be at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer or erosion may occur. The filled and cured polymeric sand joints should never be in direct contact with foot traffic or tires. Follow FLEXLOCK ULTRA SAND G2 installation steps 1 to 4 for a new paver surface.
