No need for cement and water, simply pour the contents of Part B into Part A, shake the bottle for 20 seconds and pour it into the hole around the post. The mixture expands just like an expanding foam to fill the hole, but it sets within 3 minutes forming a rock hard installation. Post Fix can be used for backfilling around posts & supports for fences, equestrian uses, lamp posts, garden fences, sports and park equipment and many other applications. No need to carry heavy bags of cement or pre-mixed cementitious products and water. No messy mixing and great for remote uses where no water is available.
