Concrete patches are the best practice for repairing the largest and widest cracks in concrete. Repair specialists typically mix the patch compounds with water and use them with a trowel. Similarly, with these steps, you can also spread a respaver along smaller cracks. In most cases, smaller cracks only need a patch.

You can easily buy materials locally to repair the surfaces of your doorway. If your driveway, patio or other concrete surface has cracks, they can often be repaired. In some cases, concrete crack repair can be a simple DIY project, in others it may require a professional concrete contractor to correct the damage, and in the most extreme cases, concrete may need to be removed and replaced. Concrete surfaces cannot be repaired with concrete.

Instead, use a concrete repair mix; these are available at home centers and online. Options include epoxy compounds, latex patch material and mortar mixes. The latter option works best for filling large cracks (or chipped edges), while the other products are suitable for cracks in concrete inch wide or narrower. Pour enough dry concrete mix into a 5 gallon bucket to repair any cracks and repair damaged areas.

Sand mixture or concrete resurfacing, which does not contain gravel, can be used if the area to be repaired is not large or deep. A standard concrete mix containing gravel works best for patching large or deep areas. The secret to fixing wide concrete cracks is to cut the sides of the crack to give it an inverted V shape. Shrinkage cracks caused by air pockets in concrete can occur within a few hours of concrete pouring.

Although concrete is a durable surface, concrete driveways deteriorate and develop cracks over the years. When this dirt settles, sometimes due to the sprinkler or rain water that passes under the concrete, the concrete is unsupported and will be more susceptible to sinking. This helps the repair material get into the crack, creating a mechanical bond in addition to the chemical bond between the patch material and the concrete. If your concrete crack has grease, visit your local hardware store or auto parts store and ask them for a product that helps remove waste.

Use a trowel to apply a concrete solution to the prepared substrate and smooth it into the crack or to form the desired shape. Unsightly cracks in concrete not only detract from the look of a garage or patio, but can also lead to additional problems as moisture seeps into the concrete. Once the cracks and other damaged spots have been filled, use the trowel to remove excess concrete and smooth the surface. Although Sakrete crack filler can be used for cracks up to this size, it is better to fill large gaps with the foam tube.

If your concrete path, yard or driveway has begun to show its age, make the necessary repairs as soon as possible. When the concrete starts to set, a broom with an extended handle can be used to give the surface a little texture. I tried the liquid concrete in the bowl, but even after successive attempts, it leaked so far and it still seems unrepaired. Concrete installations can last hundreds of years, but sooner or later, most end up developing small cracks, gaps, holes and cracks.
