IMPORTANT INSTALLATION NOTES

  1. Always refer to the latest FLEXLOCK DUST Technical Data Sheet (TDS) at Flex-lock.com before installing FLEXLOCK DUST.
  2. FLEXLOCK DUST must be installed above 59°F (15°C).
  3. FLEXLOCK DUST can only be installed if rain is not forecasted in the next 24 hours.
  4. Wet cast and natural stone sides and top surfaces must be completely dry. Do not apply if the wet cast or natural stone surface is damp or wet. The damp or wet surface will cause FLEXLOCK DUST to prematurely activate and will lead to the polymers sticking on the wet cast or natural stone surface.
  5. Do not apply if the wet cast or natural stone joints are damp or wet. This will prevent the FLEXLOCK DUST from properly sliding into the joints and obtaining very densely packed joints, which is critical to the products performance.
  6. Minimize or avoid walking on the wet cast or natural stones for 24 hours after the installation of FLEXLOCK DUST.
  7. If FLEXLOCK DUST is left lying on the wet cast or natural stone surface for a long duration, moisture can form and will activate the FLEXLOCK DUST on the wet cast or natural stone surface, staining may occur.
  8. Do not use FLEXLOCK DUST when wet cast or natural stones are installed over a concrete base. FLEXLOCK DUST is designed to function on a traditional base system. A concrete base inhibits drainage, thus the trapped water will negatively impact the product’s performance.
  9. Waterproof bag: Intact pallets or bag can be laid flat and stored outdoors. (Lay bag flat on its back, so front of the bag is facing you.)
PLEASE NOTE:
FLEXLOCK DUST becomes very firm but will detach from wet cast or natural stones if the crushed stone base has excessive movement. It will also detach from the wet cast or natural stones if the wet cast or natural 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 wet cast or natural stone areas. When installing wet cast or natural stones around an underground pool, a slope of 1/8 inch (3 mm) per linear foot away from the pool is mandatory. All wet cast or natural 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 wet cast or natural stones installation around the pool, you can use FLEXLOCK DUST. Do not sweep FLEXLOCK DUST over asphalt.

Maximum joint width: 6″ (15 cm)

REQUIRED SUB-SURFACE PREPARATION

FLEXLOCK DUST is recommended for a variety of uses, including patios, walkways and pool decks. The wet cast or natural stones must be installed on a traditional base system: maximum of 1″ (25 mm) of bedding sand, plus a minimum of 6″ (15 cm) of crushed stone compacted at 98% Proctor density. (See diagram 1 below). Adding a second layer 1″ (25 mm) of loose sand on top of the Gator Base (See Diagram 2 below) for wet cast or natural stones is also an accepted method of installation.

DIAGRAM 1

Sand or ASTM No. 9 Stone can be used as a bedding layer for under the stones

DO NOT USE WHEN STONES ARE INSTALLED OVER A CONCRETE SLAB.
DO NOT USE FOR VEHICULAR TRAFFIC.

Installation Instructions

FLEXLOCK DUST INSTALLATION STEPS FOR A NEW WET CAST OR NATURAL STONE SURFACE

STEP 1

Install the wet cast or natural stones on a maximum 1″ (25 mm) bed of sand. Make sure that there is at least 6″ (15 cm) of compacted crushed stone under the bedding sand. See diagram 1.

STEP 1
STEP 2

Make sure the wet cast or natural stone top and side surfaces are dry.

FOR NATURAL STONES: Using a hard-bristle broom, sweep FLEXLOCK DUST in between the full depth of the natural stone joints.

FOR WET CAST STONES: Using a scoop, carefully pour FLEXLOCK DUST in between the full depth of the joints and avoid getting any FLEXLOCK DUST on the wet cast stone surface.

STEP 2
STEP 3
Hit the wet cast or natural 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.
STEP 3
STEP 4
Using a soft, fine-bristle broom, sweep all excess FLEXLOCK DUST off wet cast or natural stone surfaces. Ensure that FLEXLOCK DUST lies at least 3 mm (1/8″) below the top of the wet cast or natural stones or erosion may occur.
STEP 4
STEP 5
Using a leaf blower, blow all FLEXLOCK DUST residues off wet cast or natural stone surfaces.
STEP 5
WATER ACTIVATION (IMPORTANT NOTES)
  1. Work in manageable sections, ideally about 50 sq. ft. (4.6 sq. m.) at a time, depending on temperature.
  2. Do not allow FLEXLOCK DUST to wash out of joint.
  3. Never allow paved surface to dry out during the water activation phase.
  4. Watering must be started at the lowest point of the paved surface.
  5. Use a watering gun set to shower and connected to a hose.
STEP 6
Shower a specific 50 sq. ft. (4.6 sq. m.) area for 90 seconds.
STEP 7
Continue to do the rest of the area at 50 sq. ft. (4.6 sq. m.) area for 90 seconds.
STEP 8
When the entire surface is done, rinse off any FLEXLOCK DUST residue off the surface.
STEP 6 - 7 - 8
STEP 9
Use a leaf blower to remove any excess water remaining on the wet cast or natural stone pores and crevices. This blowing action is necessary to help remove any remaining FLEXLOCK DUST residue left on wet cast or natural stone surfaces from the previous steps.
STEP 9

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.
