How to Fill Concrete Cracks

Posted on

Cracks in concrete, whether they are in walls, driveways, or sidewalks around your home are usually just cosmetic at first. It is very common in the concrete slabs will get small cracks as they settle and the soil shifts. Still, they are ugly and you probably want to cover them up as soon as possible. Usually, filling a small crack will not only cover it up, it could also slow the growth. This article explains how to fill small, cosmetic concrete cracks.

Inspect the Extent of the Damage

First of all, if your crack goes all the way through your slab or wall, you should probably not take on this project. This means that there is probably a structural issue that needs to be figured out. Simply applying some crack filler is only going to be a very temporary solution. You'll need to contact concrete services like Sunny Concrete Services LLC to truly restore the concrete. That being said, some people will still fill all of their cracks, just to make sure everything looks better.

Use Concrete Crack Filler—Not Ready Mix

Concrete crack filler is messy, but pretty easy to use. To apply it, you will want a putty knife and latex gloves. Clean any dirt out of the crack, and then you can start to work with the filler. Crack filler comes in premixed tubes, making it very easy to apply. You can usually squeeze it by hand, or with a caulk gun (depending on what type you buy) right into the crack. The important thing to do when filling concrete cracks is to only fill in the crack, and not spread the filler on top of the old concrete. Just fill the crack slightly over the top of the concrete, and then scrape away the excess with the putty knife. Make sure you keep an eye on the filler as it dries. Often, it will sink further down and settle as it dries. If so, just add some more crack filler.

Optional: Add Matching Glaze or Dye

This is the final step if your concrete is also dyed or glazed. Applying a glaze or dye to match the existing concrete can be a little tricky because of fading. Even if you do get the exact same glaze or dye, it might not match because the existing concrete will be lighter due to sun fading. That being said, it will look better to have a slightly mismatched glaze than to have no glaze at all over the recently filled crack.

Once you learn how to master this simple technique, you can quickly fill cracks in your concrete quickly and easily.
