Repairing asphalt is a little different than repairing concrete. The jobs are similar but different in many ways. That is, in order to patch asphalt cracks, you need to use different products and techniques. Some people mistakenly use the same techniques and crack fillers for both concrete and asphalt repairs. This article looks at the main differences between asphalt and concrete crack repair.
Use the Right Products
Asphalt and concrete crack filler both come in premixed solutions that are sold at most home improvement stores. When it comes to repairing concrete, you can use concrete patch that comes in large tubs or caulk tubes. This is usually a grainy substance that is similar to real concrete, except that it has adhesive mixed in to make it much stickier so it can bond with old, rough concrete surfaces.
Asphalt crack filler is even more liquid and stickier than concrete crack filler. It is more like a gooey gel that can be a little messy to work with, so make sure you wear disposable latex gloves. Asphalt crack filler can also be called "patch". Patch and crack filler are usually the exact same formula, so don't worry.
How To Properly Fill Cracks
The most important difference, besides the fact that you use different products, is how you actually fill the crack. When you apply asphalt filler over a cracked asphalt surface, you want it to fill in the crack gap, but you also need to spread it onto the top of the asphalt. You need to spread the asphalt filler over the asphalt in a swath that is several inches wider than actual crack.
This is not what you do when you are repairing concrete cracks. Concrete crack filler just goes inside the actual crack. You don't want to spread it onto the top of the concrete, or else it will crumble away. You will probably use a metal putty knife to spread the concrete crack filler, while you need to use a rubber squeegee to spread the asphalt patch.
It is worth learning how to repair both asphalt and concrete if you have both of them on your property. You obviously don't want to use asphalt filler on concrete, just like you don't want to use concrete filler on asphalt. It is important to repair small cracks on either surface because they can and will become bigger over time if they are left untreated.
