It can be pretty overwhelming to choose an asphalt driveway sealer given the large number of varieties to select from. This is why we have come up with a list of the different types of asphalt sealers so that you can make a well-informed decision while purchasing the same.
- Coal Tar Sealer
Coal tar emulsion is the leading choice of asphalt sealcoating. It can keep your driveway protected from both organic and inorganic materials which can cause damage. The USP of coal tar emulsion lies in its ability to resist gasoline, water, and oil. Coal tar emulsion is not petroleum-based making it more resistant to pollutants. It can also keep asphalt protected from the harmful UV radiation which is infamous for hardening the asphalt layers through moisture loss and causing cracks. Refined coal and some additives go into the composition of coal tar sealants for adding to its longevity when compared with its asphalt-based peers. They usually last up to five years depending upon the traffic received by the pavement.
The inherent disadvantage of coal tar sealer lies in the volatile organic compound it emits during the application process which has a foul odor and is harmful to our environment. While applying coal tar sealer in a DIY manner, you need to make sure that it doesn’t come in contact with your bare skin as it irritates. Inhaling the fumes might also trigger respiratory irritation. This is why you need to wear protective gear during the application process. Another disadvantage of coal tar sealer is its natural grey color which lacks the shine of fresh black asphalt. Often sealer additives are used to impart a dark black hue to the coal tar sealcoating.
· Asphalt Sealer
Asphalt-based sealers are commonly sold in the market and have gained popularity amongst residential and industrial users due to their water-resisting capabilities. However, you cannot expect heavy-duty protection from direct sunlight, gasoline, and oil. Asphalt sealer is made using crude and some additives. It doesn’t last as long as its former peer but is comparatively more environment friendly as it doesn’t emit a lot of volatile organic compounds. The dark color of asphalt sealers makes them more aesthetically pleasing although you might have to redo the sealcoating at the end of each season.
· Acrylic Polymer Sealer
This is a synthetic variety of sealer which is composed of different man-made chemicals. Acrylic Polymer sealers can keep your driveway protected from gasoline, water, oil, and direct sunlight. It also doesn’t emit as many volatile organic compounds as that of a coal tar sealer. The acrylic polymer sealers come with an expensive price tag. But if you are looking for an extremely durable option that packs in all the wellnesses of coal tar and asphalt sealants, then you can go ahead with this variety. Such sealers are available in different color choices which have made them a top choice for shopping mall parking lots and tennis courts. They can last up to seven years depending upon the traffic received.
· Fast-Dry Sealer
Just as the name suggests, these sealers dry out in less than an hour. They are mostly used by the owners of big parking lots and road crews. The fast-dry sealer might not suit the requirement of homeowners as they are pretty expensive and have to be bought in bulk.
Final Words
The asphalt sealer you choose must be in sync with your specific driveway requirements. You can get an asphalt sealer 55 gallon drum or other sizes that can assist with proper driveway maintenance. While buying the sealer, it is always advisable to take note of its warranty and other manufacturer recommendations.
