How to Fix Indoor Concrete Cracks

Indoor concrete can experience just as much wear and tear as outdoor concrete. With time, these small chips and cracks are inevitable but typically don’t signify any underlying structural issues that need resurfacing. However, concrete cracks should be quickly tended to before they can spread. Please continue reading below as we discuss how to fix indoor concrete cracks between a quarter and a half-inch wide. 
Materials NeededTo fill your concrete cracks, you will need the following materials:

• Hammer
• Gloves
• Vacuum
• Paintbrush
• Trowel
• Wire brush
• Cold chisel
• Safety glasses
• Concrete bonding adhesive
• Dry concrete mix
• Patience

Once you’ve gathered the materials, put your gloves on and use the wire brush to clean both in and around the crack. After you’ve swept away the loose dirt, vacuum the crack. If oil, grease, or dirt can still be seen inside or around the area, make sure that you scrub it thoroughly. 
Next, put on your safety glasses and use your hammer and cold chisel to undercut the border of the crack. The purpose of this step is to hold the patch in place. After this, take your paintbrush and coat the surface of the crack with the concrete bonding adhesive. 
Once you are sure that the adhesive has dried completely, you can begin following the instructions on your concrete bag to mix the concrete. Fill the crack with the mixture and then smooth and level the surface using your trowel. Finally, allow the patch to cure for the recommended time as stated on the bag. ​
