Your driveway leads visitors to your home. It is the first thing most people will notice as they approach your house. An asphalt driveway increases your curb appeal and home’s overall value. Maintaining your driveway is an essential part of prolonging its lifespan and protecting your investment.
In general, most professionals recommend you seal your asphalt driveway every one to three years. Many factors affect the rate in which you need to apply a fresh sealant. The environment plays a big role here. Water is the most damaging element when it comes to your asphalt. At its core, asphalt is flexible. When water seeps into cracks in your driveway, it can damage the soil or gravel foundation on which the asphalt sits. This can create weak points. As vehicles drive over these areas, the asphalt flexes. The rippling effect may not be noticeable to the naked eye, but the asphalt itself feels the impact. These weakened zones can create cracking at the site or elsewhere along your driveway.
In addition to water seeping into your asphalt, the sun and oxygen can also damage your driveway. UV rays and oxygen both erode the adhesive materials used to keep the stones in asphalt together. Oils exist in your asphalt. While they do need to dry for six months before a sealant is applied, there comes a point when UV rays and oxygen have over-dried these oils. This can also lead to cracking.
Sealing your asphalt provides increased protection from more than just the elements. Seal coating preserves the color of your driveway, keeping it fresh and beautiful. In fact, if you should see the color of the individual stones of your asphalt, professionals recommend a fresh seal coating. In addition to protecting its beauty, seal coating can help reduce stains. Asphalt is porous in nature. This makes it inclined to gathering dirt and staining. Sealing your driveway makes these pores shallower and less likely to accumulate debris.
It is important to seal coat your asphalt driveway in order to prolong its lifespan. Whether protecting your asphalt from the elements, dirt, or general wear and tear – seal coating your driveway is one of the best ways to protect your investment. Sealants are available at your local hardware store. Professional services are also available should you want a more expert seal coating application.
