Why Fast 2K

Fast 2K is an award-winning innovation, much faster and more convenient than concrete for setting fence posts, mail boxes, signs and much more! Fast 2K uses the same technology applied by Royal Adhesives & Sealants Canada to set utility poles for almost 15 years.


  • No more handling heavy bags of concrete: one 2 lb (1kg) bag replaces 2 x 50lb (23kg) bags of concrete
  • No water required
  • No messy concrete mixing
  • One 2 lb (1kg) bag sets a 4×4 post (10x10cm) in a 8” (20cm) by 3 ft (91cm) deep hole
  • No wide holes required: for example, a 4×4 (10x10cm) post can be easily set with Fast 2K in a 6” (15cm) hole rather than in an 8” (20cm) or wider hole typically used with concrete. Narrower holes can cut material costs in half as installers can easily double the number of posts set with the same number of Fast 2K bags.
  • Fast 2K is a convenient liquid mixture when poured into the hole, whereas concrete does not flow easily
  • Fast 2K can be kept and used outside in summer and winter, even when temperatures are as low as -30oC (-20oF) or as high as 38°C (100°F) –  just keep the Fast 2K bag acclimatized at 22°C – 25°C (72°F – 77°F) for at least two hours before using
  • Warehouse space savings: 1 pallet of Fast 2K replaces over 20 pallets of concrete bags
  • Unlike concrete, there is no waste of material due to torn bags


  • Same advanced technology used to set utility poles for almost 15 years
  • Adheres to wood, vinyl and metals posts, as well as to the ground better than concrete
  • Bonds to itself, so users can always top up if necessary
  • Waterproof: Fast 2K is hydrophobic or insensitive to water, so it helps to protect the wood post against rotting. On the other hand, concrete continues to absorb water allowing the post to deteriorate much faster. Rotting is the main reason why fences need to be replaced every few years.
  • Can be used during winter


  • Mixes in just 30 seconds
  • Sets posts in as little as 5 minutes
  • Fences can start to be built in 15-30 minutes
  • No time wasted loading and unloading heavy concrete bags
  • No time wasted forming, pouring, curing and cleaning up concrete
  • Jobs can be completed without having to move crew and equipment in and out of the job
