Learning how to repair cracks in concrete is pretty simple as far as repair jobs go. With 3 simple steps the crack will be filled and you can move on to bigger projects.
In order to properly fill in the crack, you need to first make sure the crack is clear of loose debris that will cause the filling to be unsecured. Clean out the crack and any surrounding dirt and oil. Use a grease-fighting cleaner to remove oil so that the filler can bond properly with the concrete. To clear out any debris inside the crack it is a good idea to sweep the area and use a vacuum along the crack.
Depending on what type of filler you are using, be sure
to prepare the mixture according to the packaged instructions. Some fillers will only require you to cut off the tip of a nozzle while others will require you to mix ingredients until you have the right consistency. Once the filler is prepped, start to fill in the crack. Make sure to add in enough of the mixture to cover the entire crack. Wait a few minutes and check to see if the filler has settled at all. If it has, fill in whatever areas are in need of more of the solution. Then, use a trowel to smooth out the filler over the crack. This will create a smooth surface. If you are working with a rougher concrete surface, use a broom to create a rough look to match the area.
Let the concrete filler cure according to the package instructions. It is usually easiest to let the filler cure overnight as it is less likely to be disturbed. Also, if you let it cure overnight, you don’t have to sit around and wait, you can just sleep through the entire time.
Once it has cured, check for any spots that need refilling. Repeat Step 2 and 3 as needed. Once you are done filling the crack, it would be wise of you to seal the area. As concrete is a highly porous material, any liquid can cause stains or even create more cracks. Sealing concrete is a much faster task than filling a crack. As stated before, learning how to repair cracks in concrete is pretty simple. Anyone can do it with a little bit of work and patience.
