Crack filling is a relatively simple procedure that’s essential for a professional asphalt repairperson to understand. Asphalt, while highly dependable, does fall victim to father time and mother nature. Extreme weather conditions, such as seasonal rain, snowfall, and frost, all chip away at the structural integrity of parking lots and driveways.
Over time, cracks develop that lower the curb appeal of a house or building. These cracks will cause even more catastrophic damages that require more complicated repairs when left untreated. Here are some tips on how to work with asphalt crack filler to better improve the quality of your services.
Before we jump into the proper use of asphalt crack filler, it’s essential that you understand the importance of surface prep. Like any outside surface, driveways and parking lots collect debris and other objects that both damage the asphalt and hinder repairs. These objects include trash, dirt, surface water and oil, and branches and leaves.
Prior to crack filling, you must clean off the surface to ensure the best possible results. Some cracks have vegetation growing within them, so remove any plants or grass if needed. Then, use a wire brush to clean out any loose debris. Lastly, wash the surface down and allow it to dry.
Unfortunately, there are more preparations in store before you begin crack filling. First and foremost, your cracks require some more maintenance and measuring. If your surface has dried and there are still impurities, you must repeat the surface prep for that area. Next, ensure that your crack is no wider than 3/4 of an inch—damages bigger than this requires more extensive equipment and more powerful bonding agents.
Next, prep your filler substance. If you’re using a tubed product, you won’t need to mix the substance. Any other form of filler will require thorough mixing to ensure the best possible results. Lastly, manipulate the spout to the exact size of the crack to avoid over or under pouring.
Now it’s time to fill those cracks! First, you must fill damages flush to the adjacent pavement. This ensures an accurate and effective filling. Next, taper off the pour so that the substance is even to the height of the surrounding surface. You absolutely don’t want to overfill cracks.
Give these areas 24 hours to fully dry and add a second coat if the filler has absorbed slightly into the asphalt. Don’t use the repaired surface for 24-48 hours after your final application of filler.
