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.
When maintaining the paver surface, apply Gator Shampoo to clean the entire paved surface including the paver joints. Wash, rinse and remove any residue by using a hose and a watering gun set to shower with the normal maximum water pressure from any residential or commercial building (typically 80 psi/550 kPa).
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.
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).
