8 Different Types of Driveway Sealers 8 Different Types of Driveway Sealers

Driveway sealers play an important role in the protection of the asphalt, brick or concrete that makes up your driveway. There are several different types of driveway sealers available, all of which have their advantages and drawbacks. Depending on the condition of your driveway and the amount of protection you require, you can chose from the below options.

1 – Coal Tar Sealer

Coal tar sealants are made from coal tar, sand, clay, polymers and other additives that give it pliability, ease of application and resistance to the elements. They are the most durable and long lasting option and last for many years. These sealers are impervious to gasoline and other fluids from vehicles. They are also resistant to fading and discoloration from intense sunlight. They are also quite affordable. The drawbacks of coal tar sealers include low environment friendliness, high level of volatile organic compounds, risk to health and possibility of skin irritation.

2 – Asphalt Sealer

Asphalt sealers are composed primarily of asphalt. They are slightly higher priced than coal tar sealers. However, they are much safer options if you consider the environment and your health. They emit negligible levels of volatile organic compounds and are also safe and easy to apply. However, they can degrade just like an asphalt driveway. After 3 or 4 years of exposure to the sun, moisture and automobile fluids, an asphalt sealer will have to be replaced with a new coating.

3 – Acrylic Sealer

Acrylic sealers are entirely synthetic and contain polymers and acrylic as the main ingredients. They are high on price, but they have none of the drawbacks of asphalt or coal tar sealers. Many professional settings see the use of these high quality sealers, which provide years of protection. Acrylic sealers are also available in many colors.

4 – Water Based Sealer

Water based sealers are more environmentally friendly options, just like paints. They offer good coverage, but may not be as long lasting or durable as oil based sealers.

5 – Oil Based Sealer

Oil based sealers are based on grease or petroleum and are may emit more volatile organic compounds that are unsafe for health. They do, however, provide good resistance against the elements and may last longer than water based sealers.

6 – Crack Filler Sealer

Crack filler sealers are available in hot-applied and cold-applied versions. The hot-applied versions require the use of a torch for simultaneous heating of the filler as you apply it between the cracks. The cold-applied fillers can be applied with a caulking gun.  The hot versions are suitable for smaller cracks.

7 – Epoxy Sealers

For concrete driveways, epoxy sealers provide a durable coating that protects the driveway from external elements such as chemicals, gasoline, excessive heat and cold. It reduces the tendency of cracking when concrete is subjected to temperature fluctuations.

8 – Linseed Oil Based Sealers

Linseed oil has been used as a sealer on concrete before the advent of commercial precuts. It is an effective sealer, preservative and protective agent that you can use to cover your concrete driveway. It is also one of the safest options available.
