How to Repair Cracks in Concrete

Do you see the concrete in your floors or driveway slowly developing small cracks? Over time, concrete surfaces can develop cracks due to wear and tear brought about by regular use and exposure to the harsh elements in Australia. In addition to spoiling the look of the surface, it can also weaken the overall structure of the flooring and leave it vulnerable to further damage. Cracks in concrete should be repaired the moment they are first spotted. This is an easy process and one that you can do yourself, following these steps –
• To start off with, perform regular cleaning of your concrete surface with a vacuum cleaner, concentrating particularly on the area around the crack.
• For the next step, you need a chisel and hammer. Use the chisel to chisel out the crack, creating a moderately deep cut which is angled towards the back. Take care not to exert too much force and chip away only small amount of concrete with each hit of the hammer to ensure that you hit the right depth and the right angle consistently.
• Clean out the chiselled crack and remove all debris with the help of a wire brush or an electric brush. Finish with another pass of the vacuum cleaner to remove final debris and dust.
• Using a thin paint brush, apply a layer of bonding adhesive to the inside surface of the crack, taking care not to miss out on any part.
• To execute the next and most important step, you would need concrete patching compound which you can easily acquire from any local hardware store. Opt for a vinyl reinforced compound for better strength and durability. Fill in the crack with the mixed compound and feather on the top with the help of a trowel to ensure that the surface is level with the rest of your flooring.
