FLEXLOCK SAND 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″ (2.5 cm) of bedding sand. The lower layer must have a minimum of 6″ (15 cm) of crushed stone compacted at 98% Proctor density. (See diagram below)
NEVER USE FLEXLOCK SAND WHEN PAVERS ARE INSTALLED ON A CONCRETE SLAB. INSTEAD, USE FLEXLOCK ULTRA SAND.
Spread FLEXLOCK SAND polymeric sand with hard-bristle broom. Make sure the FLEXLOCK SAND completely fills the joints. Do not use other materials in the joints.
Leave a layer of FLEXLOCK SAND on the surface to aid in vibrating and consolidating FLEXLOCK SAND polymeric sand into joints. For textured or pre-finished surfaces, we recommend to remove all the polymeric sand from the paver or slab surface prior to using the plate or roller compactor.
Vibrate the FLEXLOCK SAND into the paver joints using a vibratory plate or roller compactor. A rubber pad is recommended. A roller compactor is best for slab installation.
Sweep off excess FLEXLOCK SAND polymeric sand from the paved surface, first with a hard-bristle broom, then a soft bristle broom. 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.
Use a leaf blower to remove all remaining FLEXLOCK SAND residue from the paver surface.
Shower and rinse simultaneously on a section of approximately 100 sq. ft. (10 sq. m.) so as to eliminate any FLEXLOCK SAND residue left on the pavers. Any FLEXLOCK SAND residue should go directly into the paver joints. Wait no longer than 2 to 3 minutes. Proceed to STEP 9.
Shower and rinse simultaneously, so as to eliminate any FLEXLOCK SAND residue. Any residue should go directly into the paver joints. However, stop showering when you see water retention on the paver joints. Wait no longer than 2 to 3 minutes. Proceed to STEP 10. Note: Repeat the directions of steps 7 to 9 for all other areas that have not been showered with water.
Use a leaf blower to remove any excess water remaining on the paver pores and crevices. This blowing action is necessary to help remove any remaining FLEXLOCK SAND residue left on paver surfaces from the previous steps. Note: FLEXLOCK SAND, sets within 1 hour after water activation at above 32ºF (0ºC) (No rain should occur within 1 hour after water activation).
The water used in steps 7 to 9 will activate a bonding action as well as condensing FLEXLOCK SAND in the joints. It is important to water the FLEXLOCK SAND a total of 3 times, as per steps 7, 8 and 9. Too little water will not properly activate the FLEXLOCK SAND and will reduce the final performance. If steps 7 to 10 are not done properly, a white haze may appear on paver surface after installation. This is due to excess FLEXLOCK SAND residue left on paver surfaces. This haze will dissipate over time, or it could be removed by using Gator Clean Efflorescence Cleaner.
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 SAND 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 installation steps 1 to 10 for a new paver surface.
