Technical Information:
Dig a hole to recommended specifications. Fill to about one third to half full with water. In sandy soils, use a slurry of Post Fix and water to line the sides. Place post in the hold. Pour in Post Fix at a steady rate around the post while tamping to ensure thorough mixing. Bring dry powder up to the surface of the water. Add a small amount of extra water if any dry powder remains. Tamp surface to eliminate air voids.
Align post to the desired position. No bracing required. Post Fix sets in approximately 5 to 10 minutes. Cold weather will slightly retard the set. Warm water may be used in cold conditions to speed up the set. Your post is fixed in the position you wanted. Cover top of the hole with grass or earth.
