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, Graphite Grey, Ivory and Onyx Black. 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.
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 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 below the edge or chamfer of the paver.
Use a leaf blower to remove all remaining Supersand Bond residue from the paved surface.
Shower water on a specific water area of 100 sq.ft., wait no longer than 2 to 3 minutes. Proceed to STEP 8.
Shower and rinse simultaneously on a section of approximately 100 sq. ft. 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.
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 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.

All Flexlock Polymeric sand can be stored outside
New waterproof bag, an advanced progressive solution for long-term storage of Flexlock Polymeric Sand and Dust products. Whether winter, spring, summer, or fall your polymeric sand and dust is protected.
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. Other polymeric sands require you to come back the following day to finish your work, and potential rainfall during the same day as the sand’s application would normally wash out the sand from the paver joints. But with Flexlock, you will be able to collect your dues earlier for work done better and sooner.
Also, who else in the polymeric sand industry but Flexlock enables you to perform this work at any temperature above 32°F (0°C), start your season earlier and extend it at least two months? With the competition, you have to wait for Mother Nature to give you a comfortable 59°F (15°C), you get two months less work time and a lower profit margin.
