Best Sealant for Sealing an Asphalt Driveway Best Sealant for Sealing an Asphalt Driveway

You need to choose the best type of sealer available for sealing an asphalt driveway so that it lasts for a long time without damage.

Coal Tar Asphalt Sealer

While water based sealers are definitely an option for anyone who wants to seal their asphalt driveway, as they produce less pollution, coal tar sealers are usually the way to go. This is because of the many advantages they have over other types of sealers. For starters, coal tar sealers are resistant to many of the chemicals that can commonly end up poured onto a driveway and damaging its seal. This type of seal will not be greatly effected by chemicals such as transmission fluid, gas, brake fluid, and oil.

Further Advantages

In addition to this advantage, coal tar asphalt sealers have a great deal of resistance to ultraviolet light. This causes driveways sealed with coal tar to keep their color for a longer period of time. Coal tar sealers are also very flexible. While this might not seem very important for a driveway, the truth is that asphalt will expand when heated and contract when cooled. Because of this, having a flexible seal that does not crack is quite important. Finally, coal tar is completely safe and will not harm humans when used for this purpose.
