Seal Coating: What Is It?
Sealcoating is also called pavement sealing. It involves the application of a protective coating, as a means of offering additional protection to asphalt pavements. This acts as a means of protection against UV damage, oils, as well as water.
Benefits Of The Seal Coating
The pavement sealer or seal coat is the coating designed for those pavements that are made of asphalt. The seal coating is meant to increase the lifespan of those asphalt pavements, as it helps to prevent anti-skid and friction that usually besiege exposed aggregates.
Asphalt-based pavements are known to be susceptible to damage, and the seal coat, when applied on it, is used to prevent the damage.
Sealcoat: Its Various Types
Since every pavement sealcoat comes with various capacities, you should note that it will work differently. A type of pavement sealcoat should not be expected to work exactly like another type because they come with different characteristics, as well advantages and disadvantages.
The refined tar-based sealer is known to give great protection against elements related to chemical and water reaction. This is great for those that want their asphalt driveway to last for a very long time. Since it is the most efficacious of the three, it usually has a higher cost than its counterparts.
When the sealer is an asphalt-based one, it offers little protection against those elements, especially the climates and chemical. This is the least efficacious sealer of the three, and when its strength as concerned, it is lower than its counterparts. It has a low pricing too.
As for the Petroleum-based sealer, it is known to give good protection against chemicals, as well as water, though it lies between the two aforementioned sealers.
Every sealer wears differently, and this is another difference between them. If you want a sealer that doesn’t wear a lot, try out the refined tar-based sealer. It usually takes a long while before it wears, as it is known to last for as long as five years. Once five years elapse, you can consider applying another sealer, and renovating the part of the asphalt driveway that needs light renovation.
As for the asphalt-based sealer, it can stay for as long as one to even three years.
The Petroleum-based sealer, as usual, is said to orbit between the asphalt, as well as the refined tar.
There may have been concerns that have arisen because of the usage of sealers. Some have said that coal tar-based sealers are bad for the environment. In North America, there have been states that have continuously placed bans on the coal tar sealants. This is a report done by the UnitedStates Geological Survey.
Pavement sealers are of three kinds, and they are used based on the preference of the contractor, and how the environment is. Most times, your contractor knows right and understands what type of sealer would function well. They come with their pros and cons, and if used well can stand the test of time.
