In case of filling the gaps between concrete and any other material such as metal, bricks or woods, silicone caulk is the best option to go for. Because of silicon’s high elasticity, when it is used in cracks, it will not even break. Normally, during temperature change or weathering, the materials expand or contracts.

Clean the surface you want the filler to apply on

Before using any type of concrete filler, you need to make sure that there is no dirt or oil present on the floor. If there remains any, use a cleaning cloth and spray that cleans grease. This will make the bonding of the filler and the cement stronger.

2.

Clean the borders of the crack

Gently clean the border of the crack, if there are any pieces of broken concrete by its side. Use a hammer to do the job but be careful it doesn’t increase the crack. Use a hammer and a chisel to get rid of any of the large pieces present in the crack. Hold the chisel at one hand at an angle, and pound with the hammer so that the crack chisels out. This is called "keying." The hole inside gets much bigger than it is shown on the surface. This will help to get the base filled with the patch or filler and will be stronger.

3.

Vacuum and Brush

Once the keying job is done, it is very important to clean the dust and pieces from the sides of the crack. Use a broom or a vacuum to clean the sides of the crack.

4.

Use the filler

Now the concrete filler or the concrete patch is ready to use. Gently open the seal of the product and apply it to the cut. Do follow the direction of the product written on it or do refer to a video in case you do not understand. Check the cracks for some times if there is any bubble in it or it has filled completely. Use a cloth to smoothen the crack filler on the surface.

5.

Leave it to cure

Allow the crack filler for some time to get it cured and dried up. Different filler has a different time to get cured. Do follow the manufacturers' instructions on the given product. Once it gets dried up a bit, check if any more patch is needed.

6.

Seal the concrete
