1. Rapid Set Time
It sets in 20 to 40 minutes, allowing you to complete projects like installing posts or making repairs much faster than with traditional concrete.

Despite its fast-setting nature, the concrete reaches a compressive strength of 4000 psi (27.6 MPa) after 28 days, making it incredibly durable for long-term use.
3. No Mixing Required for Certain Uses
For post-setting and similar applications, you can pour the dry mix directly into the hole and then add water—no pre-mixing required.
4. All-Purpose Versatility
Great for setting fence posts, deck footings, swing sets, signs, mailboxes, and for pouring slabs and curbs.
5. Available in Multiple Sizes
You can find it in manageable bag sizes, making it easy to transport, store, and handle even in tight spaces.
Common Applications for Quikrete Fast Setting Concrete Mix
Thanks to its versatility and quick setting time, this concrete mix is perfect for a variety of projects:
– Fence and Mailbox Posts
Simply dig a hole, pour in the dry mix, add water, and you’re done. The post will be secure in under an hour.
– Deck Footings and Support Beams
Build your outdoor structures faster with quick-drying concrete that meets load-bearing requirements.
– Patios and Walkways
Use for small slab work where traditional concrete would take too long to cure.

– Signage and Poles
Perfect for setting signs in commercial and residential areas where rapid installation is key.
How to Use Quikrete Fast Setting Concrete Mix
One of the biggest advantages of Quikrete Fast Setting Concrete Mix is how simple it is to use. Here’s a step-by-step guide for using it to set posts:
Step 1: Dig the Hole
Create a hole about one-third the length of your post and three times its diameter.
Step 2: Position the Post
Place the post in the hole, ensuring it’s level and centered.
Step 3: Pour the Dry Mix
Empty the concrete mix into the hole around the post. You’ll typically need 1½ bags per 4″x4″ post in a hole that’s 12″ deep and 12″ in diameter.
Step 4: Add Water
Pour approximately 1 gallon (3.8 liters) of water per 50 lb bag into the hole. Allow the water to completely saturate the concrete.
Step 5: Allow to Set
Hold the post in place for a few minutes until the concrete begins to stiffen. The post should be secure in about 30–40 minutes.
Tips for Best Results

Don’t overwater. Too much water can weaken the final strength.
-
Avoid working in extreme temperatures. For best results, apply the product between 50°F and 90°F.
-
Protect from rain. Cover your project if rain is expected within a few hours of application.
-
Use gloves and a dust mask. Always wear safety gear when handling cement products.
Quikrete vs Traditional Concrete: What’s the Difference?
| Feature | Quikrete Fast Setting | Traditional Concrete |
