Asphalt Sealers: Should You Use a Sealer on Your Asphalt Driveway?

Projections show that the North American sealers market will reach a value of $914.12 million by 2027. Despite this, sealers are not always necessary and sometimes provide little to no benefit. Asphalt sealers are the perfect example, as they are often more harmful than useful. To find out why you don't need to use a sealer on your asphalt driveway, keep reading.

The Purpose of Sealers Sealers are substances that are water or solvent-based and are used to coat surfaces to offer improved protection. On concrete, for example, sealers will create a non-porous layer to stop any penetration of the pores in the concrete below. This is usually done to protect from weather exposure, grease spills, oil spills, abrasion, and any form of water. Should You Use Asphalt Sealers? To put it simply, an asphalt driveway does not need to be sealed. Some people have concerns about the state of their driveway deteriorating if not coated, but it is worth bearing in mind that many roads are made of asphalt, and they last for a very long time without any sealing. Roads are subject to the same weather conditions as regular driveways and potentially a huge amount more traffic and oil/grease spills. Asphalt naturally has several properties that make it ideal for driveways. It holds up well to both low and high temperatures. Even freezing and thawing cycles have very little effect. It is also slip-resistant, which is ideal for the icy conditions of Canadian winters. The Disadvantages Not only are asphalt sealers unnecessary, but they can actually do more bad than good. One of the dangers of asphalt sealers is to people's health. Asphalt sealers often contain chemicals that are known to cause cancer if the exposure is too high. The chemicals in these sealants are also harmful to the environment. Heavy rainwater can wash small particles from sealers into storm drains, which then flow into lakes and streams. This creates a toxic environment for the wildlife in these areas. Tar seal coats were even banned in Texas in 2005 due to the harm they can cause.
