Flexlock Dust is a unique mixture of polymer binders and calibrated stone available in Sahara Beige, Stone Grey. Once Flexlock Dust sets, it becomes very firm and locks between the stone joints while still retaining flexibility and providing a long lasting, durable jointing material. Flexlock Dust is recommended for a variety of uses including pool decks, patios, footpaths, and any other pedestrian applications.
Install the stones on a maximum 1″ bed of sand. Make sure that there is at least 6″ of compacted crushed stone under the bedding sand. See diagram 1.
Make sure the stone’s top surface is dry.
FOR NATURAL STONES: Using a hard-bristle, broom, sweep Flexlock Dust in between the full depth of the natural stone joints.
FOR WETCAST STONES: Using a scoop, carefully pour Flexlock Dust in between the full depth of the joints and avoid getting any Flexlock Dust on the wetcast stone surface.
Hit the stones with a rubber mallet; this will make the Flexlock Dust settle firmly into the joints by removing any air pockets. Repeat step 2 and this step 3 at least two more times.
Using a soft, fine-bristle broom, sweep all excess Flexlock Dust off stone surfaces. Ensure that Flexlock Dust lies at least 1/8 inch below the top of the stones.
Shower water on a specific water area of 100 sq.ft., wait no longer than 2 to 3 minutes. Proceed to STEP 7.
Shower and rinse simultaneously on a section of approximately 100 sq.ft. so as to eliminate any Flexlock Dust residue left on the stones. Any Flexlock Dust residue should go directly into the stones joints. Wait no longer than 2 to 3 minutes. Proceed to STEP 8.
Shower and rinse simultaneously, so as to eliminate any Flexlock Dust residue. Any residue should go directly into the stones joints. However, stop showering when you see water retention on the stones joints. Wait no longer than 2 to 3 minutes. Proceed to STEP 9. Note: Repeat the directions of STEPS 6 to 8 for all other areas that have not been showered with water.
Use a leaf blower to remove any excess water remaining on the stones pores and crevices. This blowing action is necessary to help remove any remaining Flexlock Dust residue left on stones surfaces from the previous steps.
IMPORTANT: The water used in step 6 will activate a bonding action as well as condensing Flexlock Dust in the joints. Too much water will undo the dense compaction obtained during step 3 and reduce the final performance of Flexlock Dust.
PLEASE NOTE: Flexlock Dust becomes very firm but will detach from stone if the crushed stone base has excessive movement. It will also detach from the stone if the stones are oscillating back and forth due to improper installation. By following Flexlock Dust installation instructions carefully, you will obtain a very hard jointing material. It should be noted that Flexlock Dust will continue to harden over time. Avoid excessive watering or flooding of stone areas. When installing stones around an underground pool, a slope of 1/8 inch (3 mm) per linear foot (30 cm) away from the pool is mandatory. All stone surfaces must have a drainage slope for the Flexlock Dust to work at its optimum. For the pool coping blocks, it is mandatory to use mortar in the joints. For the rest of the stone installation around the pool, you can use Flexlock Dust. Do not sweep Flexlock Dust over asphalt.
The quantity required depends on the shape and size of the stones as well as the width of the joints. One bag of 50 lbs (22.7 kg) of this product will cover between 20 to 30 square feet (1.86 to 2.79 m2) if the joints are about 1˝ to 2˝ (2.54 to 5.08 cm) wide and the stones are about 2˝ to 2-1/2˝ (5.08 cm to 6.35 cm) thick.

Flexlock Dust is recommended for a variety of uses, including patios, walkways and pool decks. The stones must be installed on a drainage base system: maximum of 1˝ (2.5 cm) of bedding sand, plus a minimum of 6˝ (15 cm) of crushed stone compacted at 98% Proctor density. (See diagram on left.)
