Whether in your driveway, patio, garage or pool deck, concrete crack filler is an essential repair product that hides a crack in cement surfaces and makes them unnoticeable. Filling these gaps helps to prevent water infiltration that causes long-term damage and deterioration. Using the right tool for the job helps you achieve a precise and effective crack filling.
Concrete crack filler repairing your surface, chisel or grind away any loose material in the crack to expose a clean and clear area for the filler to bond. Also, cleaning the crack with a wire brush and vacuum or air compressor removes any dirt or debris that could weaken the crack-filling process.
Next, consider the size and depth of the cracks you are filling. For hairline cracks, a caulking gun can be used to apply a concrete crack filler in a one-pass operation. However, for larger cracks requiring a more substantial repair, epoxy fillers are ideal for their strong adhesion and durability.

The weather also plays an important role in the crack-filling process. Hot conditions cause the filler to over-soften and fail, while rain and humidity prevent it from adhering properly to the cracks.
Once the crack filler is applied, smooth and finish it with a trowel, squeegee or putty knife to create a flush surface that blends in with the surrounding concrete texture. Then, let the crack filler dry and cure according to its manufacturer’s instructions to avoid premature use and ensure the full benefits of your repair.
