Setting Posts Without Mixing | QUIKRETE: Cement And Concrete ...

Project Instructions

Always take proper safety precautions when working with cement-based products, including wearing eye protection, nitrile gloves and a mask.

Step 1 Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).

Step 2 Add about 6 inches of QUIKRETE All-Purpose Gravel into the bottom of the hole. Then compact and level the gravel using a post or 2x4.

Step 3 Set the post into the hole and attach 2x4 braces to adjacent sides of the post.

Step 4 Use a level to position the post perfectly vertical.

Step 5 Fill the hole with Fast-Setting Concrete up to 3 to 4 inches below ground level.

Step 6 Pour about a gallon of water per 50 lb bag into the hole and allow the water to saturate the concrete mix.

NOTE: mix will set hard in 20 to 40 minutes

Step 7 Wait about 4 hours to begin constructing your fence or applying heavy weight to your post.
