Flexlock Sand is a unique mixture of polymer binders and calibrated sand available in Sandy Beige, Graphite Grey and Ivory. The installation of Flex Lock Sand is almost identical to using regular paver joint sand, except for the application of water. Once Flex Lock Sand sets, it becomes very firm and locks between the paver joints. This firm bond maintains pavers securely in place, being equally effective on both horizontal and sloped surface.
|Helps prevent weed sprouting.|
|Helps prevent damages caused by insects.|
|Helps prevent erosion due to climatic conditions, such as wind, rain and freezing.|
Quantity required depends on the shape and paving size as well as the width of the joints.

Flexlock Sand is recommended for a variety of uses, including pool sides, patios, foot paths, driveways, parking spaces, pavements, etc. The concrete pavers have to be installed on a drainage 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 5″ (12.5 cm) of crushed stone compacted at 95% Proctor density. (See diagram below).
Please note that this limited warranty applies only when the Flexlock Sand, Flexlock Ultra and the Flexlock Dust are used for residential purposes exclusively (home owners or contractors using the product for single or multi-unit dwellings that are exclusively for residential use).
Flexlock cannot guarantee results as it has no control over surface and sub-surface preparation and product application.
However, for a period of 10 years from purchase, Flexlock agrees that, if the product is proven to be defective, and on the condition that is was installed pursuant to the method of application of surface and sub-surface preparation described in the *installation guide, then Flexlock agrees to refund the purchase price. Proof of purchase is required for any claim. The parties agree that the refund of the purchase price as stated is the only obligation of Flexlock. In all events, Flexlock Products shall not be liable for any other damages or costs ( including removal or reinstallation of sand or pavers) whatsoever, direct or consequential, to the extent permitted by law, Flexlock excludes any implied warranty of quality merchantability or fitness for purpose.
Please note that when the Flexlock Sand, Flexlock Ultra and the Flexlock Dust are used for other purposes (mixed-use, commercial, institutional or other), the above terms apply except that the applicable period is reduced to 1 year from the purchase.
The water used in steps 4,5 & 6 will activate a bonding action as well as condense Flex Lock Sand grains in the joints. Too much water will undo the dense compaction obtained during step 2 and reduce the final performance of Flex Lock Sand. If steps 3, 4, 5, 6 and 7 are not done properly, a white haze may appear on the paver surface after the installation. This is due to excess Flex Lock Sand residue left on the paver surface. This haze will dissipate over time. It can also be removed by using a concrete efflorescence cleaner.
Using a pressure washer, remove all the existing joint filling material from the top of the pavers to the bottom. Be careful to not disturb the bedding sand under the pavers. Follow step 2 to 7 of NEW PAVER JOB instructions.
Do not apply on wet or damp surface since bonding action will cause Flex Lock Sand to stick on surface and prevent proper sliding in joint. Do not use if rain is expected within 1 hour. Avoid excessive watering or flooding of paved surfaces. When installing pavers around an underground pool, a 1/8 inch slope per linear foot from the pool is mandatory. All paver surfaces must have a drainage slope for the Flex Lock Sand to work at its optimum. For the pool coping units it is mandatory to use mortar in the joints. For the rest of the paver installation around the pool, you can use Flex Lock Sand.
-The Flex Lock Sand is ideal for narrow or large joints up to a maximum of 1″.
-Never use Flex Lock Sand when pavers are installed on a concrete slab. Over concrete slab the Flexlock Ultra is the recommended choice.
- Do not sweep over asphalt.
Flex Lock Sand is the only polymeric sand manufacturer that provides a one-hour setting time warranty. 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 Flex Lock, you will be able to collect your dues earlier for work done better and sooner.
Also, who else in the polymeric sand industry but Flex Lock enables you to perform this work at any temperature above 0°C (32°F), 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 15°C (59°F), you get two months less work time and a lower profit margin.
