Are the instructions on the concrete bag right? You just dump the bag in the hole and pour a gallon of water on top to set a post in concrete? No shaking, no stirring? Build to Made performs an extremely helpful experiment to show us just how little effort it really takes to stick a post in the ground and have it stay up forever! They cut a window into a 5-gallon bucket so that we could watch as the concrete mix becomes fully saturated over roughly 20 minutes.
What you need to set a post in concrete in a bucket
- A 50lb bag of fast-setting concrete mix (you should pick this up from your local big box store for much cheaper)
- A bucket, container or hole in the ground
- 1 gallon of water
- A post
Optional items
- A tough pair of work gloves
- A 5 gallon decorative planter
- A snap-off utility knife
Set posts in concrete with these steps
- Grab a utility knife
- Cut open the bag of concrete
- Pour the entire bag of concrete mix into the bucket
- Pour 1 gallon of water on top of the concrete mix
- Let it sit for about 4 hours, though it’ll set after 20 to 40 minutes
- Continue on with your day
