Fast 2K fence post backfill is much faster and more convenient than concrete to set fence posts, mailboxes and much more. One 2.5 lb bag of Fast 2K replaces up to 100 lb of concrete to set a 4x4 post in a hole 8" wide and 3 ft deep. No water required, no wheelbarrow, no messy mixing or clean up as with concrete. Just rub the Fast 2K bag for 30 seconds and pour inside the hole. Fast 2K expands to set wood, vinyl and metal posts in 2-5 minutes. After 15 minutes, you can start building the fence. Fast 2K can be used during the winter and is waterproof so it helps to protect the wood post against rotting. Posts can also be set with Fast 2K in much narrower holes than with concrete. For example, one can set a 4x4 post with Fast 2K in a 6" wide hole (rather than 8" holes with concrete). Fast 2K uses the same technology that has been applied to set utility poles for over 20 years.
