As long as the rest of the driveway is in good condition (no shaking, sinking, or crumbling), you can replace those small cracks with a smooth concrete surface by applying a high-quality repaving product, such as the Quikrete Concrete Repaver. Pour enough dry concrete mix into a 5 gallon bucket to repair any cracks and repair damaged areas. A sand mix or a concrete grinder, 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.
If a crack measures less than a quarter of an inch, it's an ideal candidate for simple repaving. So grab a screwdriver and scrape off any residue you see. Then use a wire brush to clean the area. And then use a blender broom or leaf blower to clear the area.
Wet the driveway with a pressure washer. Then add the Quikrete engraver, cleaner and degreaser to the machine tank and spray it on the surface. After that, attach a high-pressure nozzle to the washing machine and thoroughly clean the surface. Mix Re-Cap Quikrete Concrete Grinder with Water in a 5 Gallon Bucket.
Place a mixing paddle on a ½ inch drill bit to quickly prepare the patch material, which should have a thick consistency. Pour the mixture over the cracks and use a flat-edged trowel to force it deep into them. Allow the material to dry overnight and then mix in a much thinner batch of rejuvenator. Before applying it, moisten the concrete to prevent it from drying out too quickly.
Start by using a pressure washer to remove mold and dirt. After wetting the tile, a special masonry cleaning solution is added to the pressure washer tank and sprayed onto the surface. Crack repair products are also available as a special cement mix in small cubes. Containers range from a quart to a size of around two gallons, depending on the amount of work to be done.
Already mixed with the necessary cement and adhesive agents, you just need to add water to start working. Very small cracks are difficult to fill with this, since they must be driven into the crack with a trowel or other thin tool, but if done correctly, a lasting repair is achieved. Most concrete crack fillers are designed for cracks up to ¼ wide; if you are repairing cracks larger than ¼, using a concrete backup bar is recommended. Before setting the concrete, it's a good idea to inspect the driveway and its surroundings to find out why the concrete is cracking.
Fortunately, filling in the cracks in a concrete driveway is a simple and relatively inexpensive DIY project. If existing driveway concrete crack repair is on your home improvement list, read on for information on repairing concrete driveways cracks. Wait until the forecast indicates dry weather and the concrete surface is at least 50 degrees F. In general, you will need to thoroughly clean existing concrete with a high-power pressure washer, and then extend the grinder with a long-handled scraper.
Mix the repaver much thinner than the concrete that was used to repair cracks, making it the consistency of pancake batter. Instead of going through the expense of removing the slab and pouring a new one, you may be able to repair and re-coat existing concrete. Best of all, your concrete driveway will look new again with minimal labor and expense compared to pouring a new slab. Sold in a variety of lengths and diameters, foam backing bars are ideal for supporting a patch and preventing it from sinking into cracks as it dries and ages.
If it's wider than that, you may want to contact a contractor to make sure there isn't a major problem with the stability of your concrete. You could break the concrete slab and pour a new one when cracks form, but that would take a lot of time, leave a big mess and cost a lot of money. The patch compound should be mixed a little thinner than the cookie dough; not thin enough to pour very well, but thin enough to fill in the cracks. If you can't fill the cracks in the concrete with a product that closely matches the existing concrete, the repaired spots may be very noticeable.
If you've been out of your driveway for many years and you have some small cracks, that's to be expected, as it's inevitable that the concrete will crack. . .
