If you have an asphalt driveway, you may have heard the term "sealcoating" in the past. Knowing what sealcoating is and how sealcoating can help you maintain your driveway is an important part of caring for your asphalt pavement.
What is sealcoating?
Sealcoating is a liquid mixture that closes the pores of your asphalt driveway. This prevents the asphalt from absorbing water, oil and other liquids that rest on the surface of the driveway.
What are the benefits of sealcoating your driveway?
Sealcoating prevents your driveway from absorbing moisture, like rain and snow. Moisture that is absorbed into the driveway can destabilize the surface that the asphalt rests on, which can cause your asphalt to become cracked or develop potholes. In this way, sealcoating helps maintain the surface of your driveway. Good quality sealcoating may also prevent your driveway from becoming stained with oil from your vehicle.
If your driveway is already cracked or has a pothole, will sealcoating repair the problem?
Sealcoating is not a crack filler or a patching agent. These problems must be addressed before the sealcoat is applied.
How can you tell if your driveway needs to be sealcoated?
Driveways that need sealcoating will be fully cured (which takes two years), and will absorb water very quickly. To find out if your driveway could use a sealcoat, spray down your driveway with water from a hose. On a properly sealcoated driveway, the water will bead up on the surface of the asphalt. If the water flattens out into a wet spot that is absorbed into the asphalt, your driveway needs to be sealcoated.
Can you sealcoat your driveway as a DIY project?
Sealcoating can be done DIY. You can purchase sealcoating at a hardware store or home improvement center. To apply the sealcoat, pour it onto the driveway and use a squeegee to spread the sealcoat around on the asphalt. Start in one corner and work your way across the surface of the driveway until the entire driveway has been covered. Wear old clothes that you don't mind ruining, because this project is very messy. Follow all manufacturer's instructions during the sealcoating process to ensure a successful application.
If your driveway has many cracks and potholes, these issues will need to be addressed before sealcoating. This damage could be indicative of a moisture problem beneath your driveway. At the very least, your driveway will need to be repaired before it is sealcoated. If the damage is extensive enough, it may need to be resurfaced. Talk to an asphalt contractor to find out if your driveway needs repair or resurfacing. If you don't feel comfortable doing your own sealcoating, contact a business such as Star Paving.Share
