The Environmental Impact of Traditional Asphalt Sealant
Asphalt sealant is a common practice used to extend the lifespan of asphalt driveways, parking lots, and roads, by sealing any surface cracks and preventing water damage. However, the traditional asphalt sealant is made with coal tar, which has been found to be toxic and carcinogenic, and can lead to soil and water contamination, resulting in negative environmental impacts. Traditional asphalt sealant also contributes to air pollution and global warming, as it contains volatile organic compounds that evaporate into the air and worsen air quality.
What are the Alternatives?
Fortunately, there are eco-friendly alternatives available that can provide the same benefits of traditional asphalt sealant without causing harm to the environment or human health. Here are some of the most popular alternatives:
Bio-Based Sealant: These are sealants made from renewable and natural ingredients, such as soybean oil or sugar cane. They are non-toxic and biodegradable, and provide a long-lasting seal on asphalt surfaces. Bio-based sealants also have a lower carbon footprint compared to traditional sealants, due to their low energy use and minimal pollution.
Recycled Materials: Recycled materials, such as recycled tires or glass, can also make an excellent alternative sealant. Recycled tires, for example, are reused as a rubberized sealant, which can extend the life of asphalt surfaces, and reduce the amount of waste on landfills.
Acrylic Polymer Sealant: Synthetic acrylic polymer sealants are water-based and free of volatile organic compounds, providing a smooth, long-lasting finish that resists cracking and peeling. They are great for DIY projects and are easy to apply with a roller or a sprayer.
Benefits of Eco-Friendly Sealant
Using eco-friendly sealant alternatives offer several benefits, including:
Cost-Effective: Eco-friendly sealants are cheaper than traditional sealants, as they require fewer coats, and last longer.
Non-Toxic: They are safe for humans and animals, offering a healthier environment for all.
Environmentally Friendly: Eco-friendly sealants help reduce landfill waste, pollution, and greenhouse gas emissions, to mitigate climate change.
Better Performance: They provide a better seal and reduce the risk of cracking, chipping, and surface damage, which saves money on repair costs in the long run.
How to Apply Eco-Friendly Sealant
Applying eco-friendly sealant is similar to applying traditional sealant, with some additional steps to note:
Clean the Surface: The surface needs to be cleaned, debris removed, and cracks filled before applying the sealant. This will ensure the sealant adheres properly.
Applying the Sealant: Eco-friendly sealants can be applied in two ways; by spray or roller. Using a roller works best for smaller projects, while larger projects would require a sprayer.
Drying Time: Eco-friendly sealants have a longer drying time than traditional sealants. This is due to their water-based nature. The sealant may take up to 72 hours to dry completely, so avoid driving or walking on them during that time.
In Conclusion
Eco-friendly alternatives to traditional asphalt sealant offer a safe, affordable, and sustainable option for your pavement needs. From bio-based sealants to acrylic polymers, these sealants help protect the environment, homeowners, and their investment from costly damages.
