How To Fix Cracks In Concrete In 3 Steps

Did you know that concrete is the most widely used construction material in the world? It’s a reliable and affordable option for many projects, but unfortunately it’s not immune to damage. Concrete cracks can appear at any time due to weather damage or general wear and tear, but don’t worry—you can easily fix them with a few simple steps.

Whether you’re a DIY enthusiast or have never touched a hammer, anyone can learn how to fix cracks in concrete quickly and efficiently. All it takes is some knowledge, the right supplies, and a little bit of elbow grease. With just three easy steps, you’ll be able to repair your cracked concrete like a handyman professional!

First up, we’ll need to assess the damage and get all of our materials ready. Then we’ll fill the crack using an appropriate filler product depending on the size of the crack. Finally, we’ll smooth out the surface and seal everything up for good measure. By following these steps closely and carefully, you’ll be able to repair cracked concrete without too much hassle!

Assess The Width And Depth Of The Crack

Scoping out the severity of a split in the concrete is an essential element for a successful repair. Surveying the width and depth of the crack will provide a reliable roadmap to smooth sailing. Sizing up this surface fissure requires careful consideration and close inspection.

Casting your eyes over the crevice, you can quickly determine if this crack is too big for DIY patchwork. If the chasm exceeds one-fourth inch in width or if it’s deeper than two inches, then you’ll need to call in a professional to complete the job.

However, if it’s not too wide or deep, then you should have no problem tackling this project with basic tools and materials. Cleaning out the crack and filling it with cement or other materials are relatively simple steps that any handyman can do on their own.

Clean Out The Crack

Before starting any repairs, it’s essential to take a step back and assess the severity of the crack. The width and depth of the issue will determine the best course of action for fixing it. Now, let’s dive into how to clean out a crack in concrete like a handyman pro!

First off, you’ll want to grab all the materials you’ll need for this job. To properly clean out a crack, you’ll require:

  1. A wire brush
  2. A chisel and hammer
  3. A shop vacuum
  4. A rag or towel If you have all that, then let’s get started.

Using your wire brush, carefully remove any loose debris from inside the crack. Once that’s done, use your chisel and hammer to create an inverted “V” shape at the bottom of the crack. This will help keep your repair material in place once it’s applied. Then, use your shop vacuum to suck up any dust created by your work so far. Lastly, wipe down the sides of the cracks with a damp rag or towel to remove any residue left behind by previous steps – now we’re ready for underlayment!

Fill With Underlayment And Sand

You’ve come this far, but you ain’t done yet. We’re nearing the home stretch, so let’s get to it. It’s time to fill that crack with a few key components:

•Underlayment •Sand •Cement mixture

It’s important to make sure these materials are in tip-top shape before you use them. Start by preparing the underlayment and sand, making sure they’re free of any dirt or debris. When that’s taken care of, it’s time to move onto the cement mixture. First, mix up enough cement to completely fill the crack. Once you’ve got your perfect consistency, start filling in the crack until it’s level with the surface of the concrete around it. After that, sprinkle a layer of sand over the newly filled area and smooth out any lumps or bumps. This will ensure a nice even finish when we’re all said and done!

Now all there is to do is sit back and let it dry before taking a look at your handiwork. With this three step process, you’ll be on your way to having concrete as good as new!

Prepare The Cement Mixture

Alright, let’s move on to the final step in fixing up those concrete cracks. Before we get started, though, I know what you’re thinking: “It’s gonna be difficult, right?” Well, not necessarily. The fix is actually pretty simple – all you need is the right materials and a little bit of elbow grease.

First off, you’ll need to mix up some cement with water so it forms a paste. Make sure you have the correct ratio of cement to water – too much water and it won’t bond properly; too little and it’ll be too thick to spread into the crack. It’ll take some trial and error to get the mixture just right!

Once you’ve got your paste ready to go, you can start applying it over the crack in an even layer. Using a trowel or putty knife helps make sure that the paste gets into every nook and cranny of the crack for maximum coverage. If it’s a deep crack, consider using some kind of backer rod before adding your cement mixture – this will help keep everything secure.

Now that your patching material is in place all that’s left is for it to dry out completely before adding any sealant or underlayment for extra protection against future damage. And with that, you’re done!

Apply The Cement Mixture To The Crack

A recent survey found that nearly 60 percent of homeowners reported cracks in their concrete surfaces. As such, it’s important to know how to fix them quickly and efficiently. Here are the steps you need to take:

First, you’ll need to gather the necessary materials. These include a wire brush, a hammer and chisel, a putty knife, cement mix, and water. Once you have these items in hand, it’s time to start repairing that crack!

Second, you’ll want to create the cement mixture. To do this, combine a small amount of cement mix with an adequate amount of water. Stir your ingredients together until they form a thick paste-like consistency. This should be ready for use soon after mixing.

Last but not least, apply the cement mixture to the crack using a putty knife or trowel. You’ll want to ensure that all parts of the crack are completely filled with your homemade paste before moving on. It’s also important to remember that if you’re filling in deep cracks or holes, you may need more than one application of the cement mixture—so don’t be afraid to use extra!

Once your mixture is applied and spread evenly across the area(s) needing repair, smooth out any bumps or ridges with either the putty knife or trowel (or both!). This will help create an even surface and ensure that your repair job looks as good as new once completed!

Use A Trowel To Smooth The Surface

The cracks in the concrete may seem like an insurmountable problem, but don’t worry; with a few simple steps, it can be fixed. After patching up the cracks with a cement mixture and smoothing it out with a trowel, all that’s left is to let things set so you can enjoy your beautiful, crack-free surface.

Making sure to get into all the nooks and crannies of your concrete crack is key to making sure it doesn’t reappear. You’ll need to first use a putty knife or chisel and a hammer to widen the crack and remove any loose debris. Then, using a brush, sweep out the dust from inside the crack. Now you’re ready for step six: using a trowel—a flat tool with a handle—to smooth out the patch. This will help make sure there are no bumps or lumps in your repair job.

It’s important to make sure you spread the cement evenly along both sides of the crack and fill it up completely before you start moving on with your trowel. That way you won’t have any problems when it comes time to let your work dry. So take your time as you smooth out that surface so you can rest assured that everything looks just right!

Allow The Cement To Set

As the sun sets in the horizon, the work of filling cracks in concrete is almost done. Setting the cement is the last step to ensuring a smooth and crack-free surface. It is like putting a cherry on top of an ice cream sundae – it adds that little bit extra of finality.

As a handyman, it is important to take this final step seriously. Applying more cement than necessary can cause bumps and lumps on the surface, which will then require additional sanding and smoothing. To ensure that this does not occur, use a trowel or another flat tool to spread out just enough cement to fill the crack without going beyond its borders.

Take your time to make sure that the cement completely fills up the cracks and that no air bubbles remain. After you have ensured that all of these conditions are met, leave the cement alone for a few hours so it has time to set properly, creating a solid foundation for any future projects. With everything firmly in place, you can move onto finishing up with sealant application and create an even stronger bond between your concrete project and its surrounding area.

Apply A Sealant

Is applying a sealant the best way to fix cracks in concrete? It certainly is one of the most effective methods, and here’s why. First, it helps protect your concrete from further damage by blocking moisture from entering the crack. Second, it can improve the overall appearance of the area; many sealants come in a variety of colors to match or complement your existing concrete. Third, it provides additional strength and stability to the concrete, helping keep it from cracking again in the future. And finally, using a sealant makes maintaining your concrete much easier since you don’t have to continually monitor and repair cracks as they appear.

So what’s involved with applying a sealant? First off, you’ll need to select the right kind for your project; there are lots of options available on today’s market. Once your choice is made, make sure you read all instructions carefully before beginning. Then clean and dry out any cracks that need sealing before prepping them with some type of bonding agent like epoxy. Finally use a brush or trowel to apply an even layer of sealant over each crack – don’t forget those hard-to-reach places!

Now that you’ve sealed up those pesky cracks, next step is to cover them up with tape for added protection. We’ll get into that in just a bit…

Cover The Crack With Tape

Alright, now that the sealant’s on, we’ll cover the crack with tape. This is an important step because if you don’t cover it, the grout won’t stay in place. The best type of tape to use is a permeable fabric-backed tape—it’ll keep the grout from seeping out.

You’ll need to cut a piece big enough to cover the crack and then press it down firmly so it sticks. Make sure you press it down good and tight so there are no gaps or bubbles in the tape. Once you’ve got that done, you’re ready for the next step!

Grouting is what we use to fill in all those cracks and holes. But before you do that, make sure you have your supplies ready—you’ll need some cementitious grout mix and a trowel. Having those two things will make your job much easier!

Fill With Grout

Taking the time to fill cracks in concrete can be a laborious task, but it’s worth it to ensure the longevity of any surface! Like a handyman on a mission, it’s time to fill those cracks with grout.

To begin, grab your grout and mix it into a thick consistency. It should look like thick paste that you can easily spread over the crack. If you find yourself in need of more material, don’t be afraid to add more until you have enough.

Now it’s time for the fun part: applying the grout! You want to make sure to fill the entire crack so that no air is trapped inside. With a trowel or putty knife, carefully spread and press the grout into each crevice. Move slowly and evenly and use gentle pressure so that you don’t leave any gaps behind. When complete, take a few moments to appreciate your hard work and admire your handiwork!

With your patch job finished, now comes one last important step—smoothing out the grout. This will help create an even surface that looks perfect when dry – making all your hard work worthwhile!

Use A Trowel To Smooth The Grout

Alright, now that we’ve got the grout in there, it’s time to smooth it out. Grab yourself a trowel and start spreading it around evenly. Make sure none of the cracks are left uncovered. It helps to use a damp cloth to wipe away any excess grout from the surface of your concrete. Get it as smooth and evened out as you can – you want this repair job to look nice, after all!

Once you’re happy with how everything looks, step back and admire your work for a second – you deserve it! You’re almost done with this crack-repairing job. Now all that’s left is to allow the grout to set properly so that your patch will remain strong and durable over time.

Allow The Grout To Set

Now that the grout’s been applied, it’s time to allow it to set. This is a relatively easy process, but you’ll still want to take your time with it. First off, you’ll need to cover the repair with some tape. This will help keep the grout from drying and cracking prematurely. Make sure that you get tape that’s rated for outdoor use if you’re working on a concrete surface outdoors.

Next up, let the grout sit for at least 24 hours before removing the tape. You can check on the repair during this time by lightly touching it to make sure that it’s still wet; if not, then you should wait a bit longer before removing the tape. Once the grout has had enough time to dry, carefully remove the tape – this should be done slowly and gently so as not to disturb or damage the freshly-repaired surface.

The last step of this task is making sure that everything is looking its best. Take a look at your work and make any additional adjustments as needed – such as adding more grout or smoothing it out further with a trowel – until you’re fully satisfied with how your crack repair looks. And don’t forget to wipe off any leftover residue from the tape! With that, your concrete fix is complete and ready for action! Time to move onto what comes next: removing the tape.

Remove The Tape

It’s the final stretch, folks! You’ve done it. After all the hard work of prepping and repairing, you’re almost ready to move on. Just one more step to go – removing that pesky tape. But don’t worry, this is a piece of cake compared to what you’ve already accomplished.

Don’t be hasty now – just because this is the last step doesn’t mean you should rush through it. Take your time and make sure you do it right. This is important stuff here; if you don’t get it right then all your hard work could have been for nothing! Start by carefully peeling away the tape from the sides of the crack, then use a putty knife or a scraper to finish off any stubborn remaining bits.

That’s it! Congratulations – you’ve successfully repaired those concrete cracks and can move on with confidence in your handyman skills. Now that everything’s been cleaned up, there’s only one thing left to do – apply an epoxy or polyurethane sealant to help protect against future cracking. And with that, your concrete repair project will be complete!

Apply An Epoxy Or Polyurethane Sealant

Applying a sealant to fix cracks in concrete is like mending a broken wall – it requires proper tools and techniques to be successful. As a handyman, I know that the best way to repair these common issues is by using an epoxy or polyurethane sealant.

Installing a sealant is relatively easy, but it takes careful preparation and patience. First, make sure the area around the crack is clean and dry so that the sealant will properly adhere to the surface. Then, use a putty knife or caulking gun to apply the material into the crack until it’s full. If necessary, use a brush or roller to even out excess sealant on top of the concrete. Be sure to wear appropriate safety gear when handling any chemicals involved with this process.

Once you’ve finished repairing your concrete, keep it clean and dry for optimal results. Regularly inspect for new cracks or damage and take care of them as soon as possible. This will ensure your concrete remains in tip-top shape for years to come!

Keep The Surface Clean And Dry

Keeping a concrete surface clean and dry is essential for long-lasting repairs. It’s not just the initial fix that matters; it’s also the care taken to maintain the repair over time. Juxtaposed against the important task of applying an epoxy or polyurethane sealant, this next step in fixing cracks in concrete is no less crucial.

It’s important to prevent moisture from entering the repaired area as much as possible. To keep your concrete looking its best, here are a few handyman tips: • Clean off any debris or dirt with a wire brush or brush. • Rinse with water and use a shop vacuum to remove any remaining residue. • Inspect the crack for any standing water and clear it out if necessary. • Use a piece of cloth or tarp to cover the area when not in use.

Taking these steps will help ensure that your repair job lasts longer and looks better. A clean repair job will also minimize further damage from water and other elements getting into the crack and weakening it again. So don’t forget about this step – keeping your concrete surface clean and dry is an essential part of ensuring successful repair work!


Concluding, fixing cracks in concrete is a simple task that can easily be done by nearly anyone. With the right tools and materials, you can make your concrete look as good as new in no time. In three easy steps, you can have the job done: assess the width and depth of the crack, clean out the crack then fill with underlayment and sand. Once this is done, prepare a cement mixture and apply it to the crack. Let it set, remove any tape from around it, then finish with an epoxy or polyurethane sealant for added protection.

With these steps completed, your cracked concrete will now look almost like it was brand-spanking-new! You’ll be amazed at how quickly and easily you can fix those unsightly cracks with such minimal effort. Now you have everything you need to give your cracked concrete a much needed facelift.
