Asphalt is a popular material choice for driveways and parking lots due to its low cost and durability. However, cracks can be a frustration for home or business owners, since they can result in the destruction of asphalt surfaces if left unrepaired. While there are many ways to repair cracked asphalt, an excellent way to fix cracks is through the use of asphalt filler rope. This material is inexpensive and long-lasting, and application is simple. Below is how you can use asphalt roppe filler to fill your driveway or parking lot cracks:
What you will need
How to fill the cracks
1. Work safely - Using an extremely hot propane torch can be hazardous if you aren't careful. Always wear the appropriate safety gear, including eye protection in case bits of hot material "pop" toward your face. Gloves will keep your hands from being accidentally burned, and work boots are essential for guarding your feet. In addition, be cautious when using the torch around dry brush, grass or other flammable materials; keep a fire extinguisher or garden hose ready in case of fire.
2. Clean the crack - It is important to make the crack in the asphalt surface as clean as possible by removing debris and contaminants that might prevent the filler rope from adhering. First, spray the crack with a broad-spectrum herbicide to kill any weeds or grass that might be growing; allow the herbicide to act upon the plants, then pull up dead plant stems by hand.
Next, vigorously sweep the crack to remove dirt, sand, gravel, and organic matter. Squirt a small amount of grease-cutting liquid dish soap directly into the crack at about one ounce of soap for every yard of crack. Following that, use the garden hose and nozzle to spray a narrow jet of water into the crack to make soapy foam and wash away any remaining particles. Be sure to continue spraying until all the soap suds are dispersed from the area. Allow the crack and surrounding areas to dry completely before proceeding.
3. Soften the asphalt - Once the asphalt has dried, use the torch to soften the inside of the crack and the adjacent areas. Hold the torch head about 2 feet from the asphalt and keep it constantly moving to prevent damaging the asphalt. Once the asphalt turns black and shiny, it is ready for the repair.
4. Insert the asphalt filler rope - Remove the asphalt filler rope from its container and begin inserting it into the crack at one end. Push it into place with your fingers, and use a flat-bladed screwdriver if you have difficulty positioning it deep enough in the crack. Once the filler rope is inserted, cut the unused portion off with a utility knife.
5. Melt the filler rope - Once the asphalt filler rope is in position, apply heat to it with the propane torch. Be sure to work slowly and use as little flame as possible to heat the material. The filler rope will begin to soften and melt as it reaches the appropriate temperature; once it is melted, stop heating and move to the next section.
6. Sprinkle black sand blasting media on the repair - While the repair is still warm, sprinkle a light coat of black sand blasting media on top of the melted filler material. Step on it a few times with your work boots to push the media into the surface of the filler, then briskly sweep away the residual media from the repair site.
