Asphalt sealcoating is a great investment, which can potentially save property owners enormous amounts of money through the years. In fact, regular maintenance and occasional sealcoating can literally save tens of thousands of dollars on individual premises, and in some cases even more money.It is a bargain, to say the least.
Asphalt requires sealcoating to retain its integrity. What this means is that oil, gasoline, weather, and other things naturally cause unprotected asphalt to chemically and physically breakdown over time. Asphalt sealcoating prevents the majority of this damage. It provides a barrier.
It is not just a matter of unprotected asphalt losing color or looking bad. The problem of these liquids, even water, seeping to the base and causing erosion and strength loss are virtual certainties in time. The base of the pavement is then destroyed. Once this happens, extensive repairs or expensive replacements are often required.
In essence, what is visible about pavement is just the tip of the iceberg, or the icing on the cake. The real strength of asphalt pavement is what is below the surface, hidden from the eye. Unfortunately, it is also vulnerable to the natural and unnatural elements when unprotected and unsealed.
A couple of types of sealers are used for asphalt sealcoating pavement. These are made from coal tar and asphalt itself. Coal tar has the advantage of doing a little better job or preventing chemical breakdowns in the pavement, whereas asphalt-based products are more user-friendly and friendlier to those on the pavement a lot.
As a client, you should obtain suggestions from your particular asphalt contractor concerning which method or substance is best for your individual sealcoating job. For the most part, you probably would not notice a discernable difference. It might simply come down to the matter of supplier or distributor price, in the process.
From a practical standpoint, think of this pavement coating in the same sense as washing and then waxing a vehicle, but with more dire consequences if not done. Coating the pavement provides a sealing to protect it from its environment, and also makes it look better. This is exactly what wax/waxing does for a vehicle’s paint job, right? Very similar. It seal-in what is there, and keeps what isn’t there out.
