IMPORTANT INSTALLATION NOTES

Always refer to the latest FLEXLOCK SAND G2 Technical Data Sheet (TDS) at Flex-lock.com before installing FLEXLOCK SAND G2.
Pavers and slabs must be installed according to ICPI Tech Spec #2 traditional base (www.icpi.org) before FLEXLOCK SAND G2 installation.
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 SAND G2 to prematurely activate and will lead to the polymers sticking on the paver surface.
Do not apply if the paver joints are damp or wet. This will prevent the FLEXLOCK SAND G2 from properly sliding into the joints and obtaining very densely packed joints, which is critical to the product’s performance.
Temperature must be above 32°F (0°C) in dry conditions and no rain for at least 15 minutes after water activation.
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 SAND G2.
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 SAND G2.
Do not sweep FLEXLOCK SAND G2 over asphalt.
FLEXLOCK 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.
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 SAND G2 can be applied when pavers are installed directly on open graded aggregates that lock or choke themselves. This means the polymeric sand will not migrate through the voids. Do not apply FLEXLOCK SAND G2 when the pavers are installed directly on aggregates with large voids.

POLYMERIC SAND REQUIREMENTS

Minimum joint width: 1/8″ (3 mm)
Maximum joint width: 2″ (5 cm)
Minimum joint depth: 1 1/2″ (38 mm)

REQUIRED SUB-SURFACE PREPARATION

FLEXLOCK SAND G2 is recommended for a variety of uses including pool decks, patios, footpaths, driveways, parking spaces, pavements, etc. The concrete pavers must be installed on a traditional base system composed of 2 layers. The upper layer can have a maximum of 1″ (25 mm) of bedding sand. The lower layer must have a minimum of 6″ (15 cm) of crushed stone compacted at 98% Proctor density. (See diagrams)

C-33 sand or ASTM No. 9 stone can be used under pavers.

Traditional base system:

A minimum 2% top surface slope for proper water runoff
FLEXLOCK 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 joint width 2″ (5 cm)
Minimum depth of joint 1-1/2″ (38 mm)
Layer of bedding sand maximum of 1″ (25 mm)
Layer of 6″ (15 cm) thickness of 0-3/4″ (0-20 mm) compacted crushed stone
For light traffic applications the pavers must be completely interlocked

Installation Instructions

(For a new paver surface)

STEP 1

Spread FLEXLOCK SAND G2 with hard-bristle broom. Make sure the FLEXLOCK SAND G2 completely fills the joints. Do not use with other materials in the joints. Leave a layer of FLEXLOCK SAND G2 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 compactor.

Polymeric Sand Installation Step 1

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 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 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 SAND G2 at least 1/8″ (3 mm) below top of paver’s surface or 1/8″ (3 mm) below the chamfer.

IMPORTANT 30-30 WATER ACTIVATION NOTES FOR FLEXLOCK SAND G2

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

Step 4

FLEXLOCK SAND G2 INSTALLATION (FOR AN 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’’ deep into the joints. FLEXLOCK 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 SAND G2 installation steps 1 to 4 for a new paver surface.
