In the age of the Internet, many homeowners are turning to the World Wide Web to learn how to complete simple repair jobs themselves instead of hiring a contractor. Even if you are a seasoned DIY-er, it’s important to be knowledgeable and aware of what you are doing to complete your project correctly and on budget. Proper research into the tools, equipment and methods used is required before you start. If something goes wrong, further issues could occur that may require a professional’s fix.

Be sure to evaluate the type of crack you are dealing with before applying any fixes, as the wrong application could cause future issues. Larger cracks, those that are leaking water or appear to be structural instead of superficial should be looked at by a professional. Likewise, if the cracks seem to be moving or you’re unsure of the repair that’s needed, it’s best to get an evaluation from a professional before beginning any work.

That said, with patience and preparation, you will be on your way to taking care of business at home! Minor cracks in concrete can be fixed in a few quick steps. A thorough job will help ensure the concrete’s life is extended for years to come. Follow these simple steps when working on minor DIY home concrete crack repairs. 

Prep the Crack and Clean Away Debris

First, prep the crack. Use a chisel (or sometimes, a hammer) to clean out dirt and debris from the crack. As you do this, the small crack may become a bit larger than what you can see on its surface, but this is helpful later, when you add the bonding agent.

Next, sweep and vacuum the area to ensure all debris is gone. Any remaining bits can have a negative impact on the bonding agent and application; all debris needs to be properly disposed of. Use a wire brush as you scrub the concrete clean. If available, use a shop vacuum as well. 

Add the Bonding Agent and Concrete Filler

Now it’s time to add the bonding agent to the inside of the crack. This ensures that the repair mixture will stay set in the crack.

After you’ve added the bonding agent, add concrete filler to the crack. Be sure to place slowly and carefully to ensure it’s in the proper place. Double check the filler after a few minutes and check to see if any more should be added. Once you are satisfied with how it looks, use a trowel to smooth the filler out for a more professional look.

Apply Sealant

Once the concrete filler has had time to set, apply a sealant to boost concrete staining and help solidify the crack’s seal.

Congratulations! You have successfully patched the concrete crack.

When to Call a Professional

Remember, if you are seeing larger cracks, water is leaking in or around the cracks, or the cracks seem to be structural rather than superficial, it’s best to have a professional evaluate the solution needed before attempting any repairs yourself.
