Shutterstock For your asphalt surfaces such as driveways and park lots one of the best things that you can invest in is an asphalt sealer. Sealcoating asphalt not only protects it from the elements, like water and UV rays but enhances its overall look while also providing protection against further damage. But with so many asphalt sealers available, it can be difficult to choose the right one for your work. This article will guide you through the varieties of sealers and aid in identifying what is best suited for your requirements.
Understanding the Importance of Asphalt Sealer
First, though we may want to dig into the different types of asphalt sealers it would be nice if I back up a little and tell you why seal coating your asphalt is important. An asphalt sealer will create a layer of protection on top which can withstand the weather conditions, traffic and chemicals. Exposure to water, UV rays and heavy use can wear down the surface of asphalt over time cause cracks or potholes which is known as pavement deterioration. The right sealer will help keep your asphalt in good working order where it performs its magic without signpost maintenance activities to maintain.
Types of Asphalt Sealers
There are several types of asphalt sealers on the market, each with its own benefits. The most common ones include coal tar sealer, asphalt emulsion sealer, acrylic sealer, and polymer-modified sealer. Let’s take a closer look at each type:
1. Coal Tar Sealer
- What is it? Coal tar sealer is one of the most commonly used sealers for asphalt surfaces. Made from coal tar, this type of sealer offers excellent protection against water, oil, gasoline, and chemicals.
- Benefits: Its chemical resistance is one of the primary reasons many professionals choose coal tar sealer, making it an ideal choice for areas like parking lots, where oil and gasoline spills are common.
- Considerations: Coal tar sealers tend to have a strong odor and may require more safety precautions during application. Additionally, due to environmental concerns, coal tar sealers may be restricted or banned in certain areas.
2. Asphalt Emulsion Sealer
- What is it? Asphalt emulsion sealer is made from asphalt, water, and other additives. This type of sealer is a more environmentally friendly option compared to coal tar sealers.
- Benefits: Asphalt emulsion sealers are easy to apply, have a milder odor, and are generally safer for the environment. They also provide excellent protection against UV rays, which helps prevent asphalt from becoming brittle over time.
- Considerations: While asphalt emulsion sealer offers good protection, it may not be as resistant to chemicals like oil or gasoline as coal tar sealers. This type is best suited for residential driveways or low-traffic areas.
3. Acrylic Sealer
- What is it? Acrylic sealer is a synthetic option made from polymers and acrylics, designed for high performance and durability.
- Benefits: Acrylic sealers provide superior protection against UV rays, water, oil, and chemicals. They come in various colors, making them a popular choice for decorative purposes and high-traffic commercial areas. They also have a longer lifespan compared to other types of sealers.
- Considerations: The major drawback of acrylic sealers is their higher cost. However, their longevity and superior performance can make up for the initial investment.
4. Polymer-Modified Sealer
- What is it? Polymer-modified sealer is a hybrid blend of asphalt-based materials mixed with polymers to enhance durability and flexibility.
- Benefits: This type of sealer offers excellent adhesion, flexibility, and resistance to cracking, making it ideal for areas with high traffic or extreme weather conditions. It also provides strong resistance to chemicals and UV rays.
- Considerations: Like acrylic sealers, polymer-modified sealers tend to be more expensive, but they offer long-term value through enhanced durability.
Factors to Consider When Choosing an Asphalt Sealer
Now that you know the different types of asphalt sealers, here are some key factors to consider when choosing the right one for your project:
1. Traffic Levels
- High-traffic areas: For commercial parking lots or roads that see a lot of traffic, you’ll want a heavy-duty sealer like coal tar, polymer-modified, or acrylic sealer for maximum protection and durability.
- Low-traffic areas: For residential driveways or areas with lighter traffic, an asphalt emulsion sealer might be sufficient and more cost-effective.
2. Weather Conditions
- Hot climates: If you live in an area with intense sunlight and high temperatures, UV protection is key. Acrylic and polymer-modified sealers provide the best protection against UV damage.
- Cold climates: In regions with harsh winters and freeze-thaw cycles, flexibility and crack resistance are crucial. Polymer-modified or coal tar sealers offer better performance in these conditions.
3. Chemical Exposure
- If your asphalt surface is frequently exposed to oil, gasoline, or other chemicals (e.g., gas stations or commercial parking lots), choose a sealer with high chemical resistance. Coal tar and polymer-modified sealers are excellent options for chemical protection.
4. Budget
- Your budget will play a major role in your decision. While acrylic and polymer-modified sealers offer top-tier performance, they come with a higher price tag. If you’re working on a tight budget, asphalt emulsion sealer offers a good balance between cost and protection.
5. Environmental Impact
- If you’re concerned about environmental impact, consider choosing an asphalt emulsion or acrylic sealer. These options are generally safer for the environment and have fewer restrictions compared to coal tar sealers.
Application Method: DIY vs. Professional
Depending on how big the project you can Either Diy with a Asphalt Sealer or hire a team official based in your area. If the driveway is small, it can be easily done by you at home (only if a proper equipment available in your garage); otherwise larger congregations such as commercial parce ling or parking lots may necessitate some professional hands to ensure equal and long-lasting work. Professionals use professional grade sealers and equipment so that the job is done right.
Conclusion
Selecting an asphalt sealer can be a challenge if you do not know what to look in the product. Whether you need a highly durable product for high traffic areas or an economical solution for residential driveways, knowing the different types of sealers and factors including those related to use, weather and chemical exposure will assist in making your decision.
Regularly sealing your asphalt with the correct product can also help to improve its appearance and prolong its lifespan, allowing you some more time before having to drop thousands of dollars in repairs. Whether you decide upon a coal tar sealer, an asphalt emulsion, or even one of the new premium acrylics and polymer-modified formulas on the market today; Your choice in product should reflect your need-to-must criteria.
By properly sealing your asphalt, you will keep it intact and maintain its aesthetics for an extended period of time.
