Fast Post Anchor is a convenient alternative to concrete for setting fence posts, mailboxes, sign and barn post anchors. One bag is equivalent to one 50lb bag of concrete, providing a strong adhesive grip to wood, vinyl, and metal posts. Its waterproof and hydrophobic properties also protect posts from water-related damages, while the 30 second mix time and 15 minute set-time allow installers to start mounting hardware quickly and without extra water or crews.


  • A single bag replaces 50lb of concrete
  • Adheres to wood, vinyl and metal posts better than traditional concrete
  • Waterproof and hydrophobic (as opposed to concrete, which absorbs water), decreasing rot, rust and other water-related damages
  • Mixes in 30 seconds and sets within 15 minutes, allowing installers to start mounting hardware almost immediately without the need for moving crews, equipment or concrete
  • No water required
  • Safe for the environment and user as no harmful chemicals are released into the environment when used

Directions for use:

  • Simply mix the two-component kit, conveniently packaged in a small bag, for 30 seconds and pour the contents into the hole and let it sit for 15 minutes.

Each bag easily sets a 4" x 4" post (10cm x 10cm) in an 8"(20cm) x 3' (90cm) deep hole.
