A: Yes many people have had great success in filling cracks in their driveway. For large cracks you can pour the liquid in to make sure it fills in completely and then brush or roll over to smooth it out.
Flex-A-Fill hot asphalt crack sealant has a variety of uses ranging from driveways to parking lots, from tennis courts to highways, and even airport runways. It can seal asphalt to concrete, asphalt to asphalt, and concrete to concrete.
Repairing Cracks in Your Driveway
Cracks up to 3/4 inch wide can be repaired with a pourable or tubed asphalt patch product. A tubed product requires a caulk gun for application. Some asphalt crack filler seals cracks up to 1 inch wide.
We also do not recommend using it in situations where it is subjected to high heat or pressure (such as engine radiators) or gas tanks. We do not recommend the use of Flex Seal spray on vinyl.
Brick: For sealing gaps in brick, a silicone caulk such as DOWSIL 758 Silicone Weather Barrier Sealant is a great choice. It's waterproof and can withstand extreme temperatures, making it ideal for use around windows, doors, and other penetrations.
According to HomeAdvisor, a driveway repair professional will charge as little as $300 to fix minor concrete driveway cracks, but most homeowners can do the job on their own with a rubber or synthetic crack filler. This costs about $0.10 to $0.15 per linear foot—but watch out if cracks are larger than 1/8 of an inch.
Seal and Repair Right Away
Seal your asphalt and always make sure you repair any cracks and chips in the asphalt as soon as possible, to prevent them from getting any worse over time and use. Getting your asphalt seal coated every year or so will also make sure your pavement is safe from weather, sunlight, and more.
Asphalt crack sealing is an important step to take for the maintenance of your asphalt surface, because it helps to prevent larger maintenance projects down the road. Even the smallest cracks can easily turn into larger cracks, craters, and dangerous potholes.
Crack sealing is a more costly procedure for the pavement owner but provides substantial value due to its long life expectancy. While crack filling may only last one or two seasons depending on the cracks activity, crack sealing can last up to 8 years or more and is considered a permanent treatment.
Cracks up to ¼ inch in width can be filled with sealant.
Cracks of this nature may never get any larger, but water can seep into them, freeze, and expand, causing the cracks to widen, so it's a good idea to seal them with the flexible Advanced Polymer Concrete Crack Sealant from Quikrete.
A properly applied application of Flex Seal will last 3+ years in normal conditions. Please note that Flex Seal doesn't withstand high heat or pressure.
Once fully cured, Flex Paste can be removed with a sharp tool like a chisel or a putty knife. However, it may not be possible to remove it without damaging the surface.
Gator Patch is a great all-around asphalt patch that is ready to use right out of the pail. Get up to 20 square feet of coverage per gallon for alligatored areas, and up to 150 linear feet of 1/2" x 1/2" cracks. Repairs severely decayed asphalt for less than cutting it out and replacing.
Concrete can be used to patch almost any crack in an asphalt driveway. As we described in the steps above, you need to pull any debris, grass, or weeds out, rinse with high pressure water house, then apply a weed killer.
Mix Quikrete Re-Cap Concrete Resurfacer with water in a 5-gallon bucket. Chuck a mixing paddle in a ½-inch drill to quickly prepare the patching material, which should have a thick consistency. Fill the cracks. Pour the mixture on the cracks and use a flat-edged trowel to force it deep inside them.
Fill the crack with urethane caulk, similar to what you would use for driveway caulk. It works perfectly as a concrete expansion joint sealant. Snip the opening of the tube at a 30-degree angle, making the opening the same size as your gap.
The most commonly used grout to fill concrete cracks is Portland cement mixed with water. You need to add enough water to make a good quality grout mix. Besides cement grout, you can go with any other filler material or sealant to fill out the cracks.
You can use any suitable exterior filler to repair cracks, either using a filling knife or an applicator gun. Using an applicator gun & a masonry filler that comes in a tube may be the best option if you have deep cracks, as this will allow you to apply the filler into the crack itself.
If you need to seal junctions between walls and seal cracks in ceilings or walls then it's better to use Caulk because it dries quicker and is much more resistant to weathering and high temperatures.
