Flexlock Sand 50 Lb

Flexlock Sand is a unique mixture of polymer binders and calibrated sand available in Sandy Beige or 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. Ideal for concrete pavers and wet cast products. It sets above the freezing temperature of 32°F (0°C) and can be used for joints up to a maximum of 1″ (2.5 cm). ASTM C-144 gradation of the polymeric sand allows use in even the tightest joints. For traditional application, Flexlock Sand is set and rain safe 1 hour after water activation.
