Sealing Cracks in Concrete
Concrete is very hard and durability surface, which makes it a great choice for sidewalks, patios, and driveways. But since concrete is so hard, it can develop cracks over time from expansion and contraction, settling, or excess weight.
The quickest and easiest way to repair a crack in concrete is by filling it with a liquid concrete crack sealant, such as QUIKRETE Concrete Crack Seal, that matches the color of your concrete.
To Repair Cracks in Concrete:
Step #1: Remove Loose Material. Use a masonry chisel, screwdriver, or putty knife to remove any loose concrete from the crack.
Step #2: Clean Crack. Use a whisk broom to clean out the crack and remove any dirt or debris.
Step #3: Fill Deep Cracks. If the crack is more than 1/4″ deep, use foam backer rod to fill it within 1/4″ of the surface.
Step #4: Apply Crack Sealer. Shake up the crack sealer, and fill the crack slightly overfull to allow for shrinkage.
Step #5: Allow Sealant to Dry. A second coat can be applied after 24 hours if needed.

A concrete slab’s durability makes it ideal for a sidewalk, patio, or driveway; but because it’s so rigid at some point cracking is inevitable. The quickest, easiest way to fill those cracks is with a pre-mixed, liquid, concrete crack sealant that matches the color of concrete.
First, remove any dirt or debris from the crack. As you pour in the liquid, it fills the void and adheres to the surrounding concrete. Slightly overfilling the crack allows for settling, and a flush finish when it dries.
