High Performance Polymeric Sand
For Concrete Paver, Wetcast & Natural Stone Joints up to 1″
Flexlock Sand is a unique mixture of polymer binders and calibrated sand available in Sandy Beige and Graphite Grey. The installation of Flexlock Sand is almost identical to using regular paver joint sand except for the application of water. Once Flexlock Sand sets, it becomes very firm and locks between the paver joints while still retaining flexibility and providing a long lasting, durable jointing material. Flexlock Sand is recommended for a variety of uses including pool decks, patios, footpaths, driveways, parking spaces, pavements etc.
Spread Flexlock 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 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.
Vibrate the Flexlock Sand into the paver joints using a vibratory plate compactor. A rubber pad is recommended. A roller compactor is best for slab installation.
Joints should be filled up to 1/8 inch (3mm) below the edge or chamfer. It is best to compact in several directions to ensure there are no air gaps or voids in the joints. Repeat steps 1-3 to ensure joints are filled and consolidated. Narrow joints require more care to completely fill.
Sweep off excess Flexlock Sand from the paved surface, first with a hard-bristle broom, then a soft bristle broom. Take care to leave the height of the polymeric sand at least 1/8 inch (3mm) below the edge or chamfer of the paver surface.
Use a leaf blower to remove all remaining Flexlock Sand residue from the paved surface.
Shower water on a specific water area of 100 sq.ft., (10sq.m.) wait no longer than 2 to 3 minutes. Proceed to STEP 8.
Shower and rinse simultaneously on a section of approximately 100 sq. ft. (10sq.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. Drainage base systems, Flexlock Sand, sets within 1 hour after water activation at above 32ºF (0ºC) (No rain should occur within 1 hour after water activation).
IMPORTANT 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 FLEXLOCK CLEAN efflorescence cleaner.
If using Flexlock Sand to replace existing jointing materials, old jointing materials need to be completely cleaned out of the joints and pavers completely dry before installing Flexlock Sand. However, be careful not to disturb the bedding material under the pavers. Follow steps 1 to 10 of Flexlock Sand installation steps (for a new paver surface).
Clay Pavers: If used on clay pavers make sure they are 100% dry. Clay pavers tend to hold moisture, which can prematurely activate the Flexlock Sand while the sand is being spread over the paver surface, leaving a residue (always apply on a test area before using the Flexlock Sand on clay pavers).
Moss: Flexlock Sand will not cause nor prevent moss, mold or mildew. Moss, mold and mildew are caused by certain on site conditions including excess moisture, shade, absence of ventilation, inadequate cleaning or maintenance, presence of soil or other organic debris left on the product.
Please note: Flexlock Sand 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 when the pavers are installed directly on aggregates with large voids.

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 drainage base system composed of 2 layers. The upper layer can have a maximum of 1 inch (2.5 cm) of bedding sand. The lower layer must have a minimum of 6 inches (15.4 cm) of crushed stone compacted at 98 % Proctor density. (See diagram on the left).
Flexlock is the only polymeric sand manufacturer that provides a one-hour setting time and Flexlock enables you to perform this work at any temperature above 32°F (0°C). Collect your dues earlier for work done better and sooner and start your season earlier and extend it at least two months.
