If you notice any cracks in your concrete garage floor, it’s important to identify the source. This can be a little tricky, but there are a few things you can do to help. First, take a look around your garage and see if you can spot any water damage. If you see any wet spots, it’s likely that water got inside and caused the concrete to start to break down.
Step 2: Assessing the Severity of the Cracks
Once you’ve identified the source of the cracks, it’s time to assess the severity. To assess the severity of the cracks, you’ll need to determine how deep they are and how wide they are. You can do this by using a ruler or a measuring tape. If the cracks are more than ¼ inch deep or wide, you’ll need to repair them before they cause any more damage. To repair them, you’ll need to use a concrete repair kit.

Step 3: Cleaning and Preparing the Cracks for Repair
Once you’ve assessed the severity of the cracks, it’s time to clean and prepare them for repair. To clean the cracks, you’ll need to use a concrete cleaner. Make sure to wear gloves and eye protection, and be careful not to get the cleaner inside the cracks. After you’ve cleaned the cracks, you’ll need to prepare them for repair. Remove any dirt or debris from around the crack using a vacuum cleaner. If there’s any loose gravel or sand, use a broom to sweep away any loose particles.
Step 4: Mixing and Pour the Concrete
If you’re looking to fix hairline cracks in concrete, epoxy resin is the perfect solution. This product will not only fill up the gap but also seal the surface so water cannot penetrate. Epoxy resin is an adhesive used to fill small gaps and cracks in concrete surfaces. It comes in two forms: liquid and powder. Mix the two together until the mixture has the consistency of thick peanut butter.
Step 5: Filling the Cracks With Epoxy Resin or Other Filler
Use a putty knife to fill the cracks with epoxy resin or other filler. Make sure to fill the cracks completely and press the filler into the cracks with the putty knife. Allow the filler to dry completely before moving on to the next step. Apply a thin coat of sealant over the entire floor. Apply the mixture to the crack by brushing it into place. Let it dry completely before walking on it.
Step 6: Allowing the Repair to Cure
You should let the epoxy cure overnight before walking on it. Once the epoxy has cured, wait at least 24 hours before using the floor again. Driving on the repaired area will likely cause more damage than the crack itself. Once cured, you can use a power sander to smooth out any rough edges. After the repair has cured paint the floor with a sealant or a topcoat of paint.
