Concrete is one of the most common materials used for both commercial and residential construction. But over the years, concrete can sustain cracks and chips which will impact its safety and appearance. In these cases, you can make use of some DIY concrete repair tips.

Just take note that these are temporary solutions and there’s no substitute to professional concrete repairs.

For small cracks

Small cracks are easy to fix. It’s actually advisable to mend small damages before it became a big problem. Here’s a quick guide that you can use for concrete surface repair:

Step 1. Brush off any debris or dust that came from the cracked concrete. Use a brush and a broom and make sure that it’s clean. Don’t wash it with water since we will be applying a filler.

Step 2. Once clean, fill the small cracks with a masonry crack filler. You can purchase one that’s in a cartridge so you can apply it using a caulk gun.

You also have the option to use a vinyl concrete patching compound to fill in the cracks. It doesn’t need a bonding agent and you only need to smooth it out with a knife.

For bigger cracks

Knowing how to repair concrete cracks is different when it comes to bigger damages. Here’s what you can do:

Step 1.Undercut the crack using a chisel and a sledgehammer. Make sure that the base is wider than the surface. This will let you “key” the patch in without the risk of getting chipped off when the area is in use.

Step 2. Brush away any dust and debris just like how you did with the small cracks. This time, you’ll need to wash the area with clean water.

Step 3. Apply the patching compound and use a trowel to spread it into the cracks. Tap the patch gently to release any air pockets inside. For those using a patching mortar, make sure that you use a bonding agent first so the filler will stick to the concrete.

Step 4. Smooth the patch and let it dry naturally.

When to call for professional concrete repair

If you’re not a handyman or you don’t have the time for DIY repairs, you can always call for professional help. Beyond DIY fixes, a professional concrete repair will use the right products and skills so the solution will last longer.

Also, you can count on the guarantee of the repairs. If any problems arise, you can call the contractor to have it checked.

Here are some signs that you need a professional concrete repair service:

Uneven surface. If the concrete surface sustained more damages and it’s becoming uneven, it’s time to invest for long-term solutions.

Weathered appearance. For commercial establishments, the look of their place matters a lot to their customers. For worn-out concrete, it’s best to have it redone to improve the aesthetics of your property.


DIY concrete repair is an easy-fix to small damages. However, when large problems occur, you need to tap the help of professional repair contractors to do the job.
