Sealcoating Mistakes That Cost You Money

Your asphalt pavement is a significant investment. Whether it's a driveway for your home or a parking lot for your business, you want it to last as long as possible. Sealcoating is one of the most effective ways to protect and extend the life of your asphalt, shielding it from the harsh sun, rain, and chemical spills common in Lake County, FL.
However, a poorly executed sealcoating job can do more harm than good. It can lead to premature cracking, flaking, and an overall shorter lifespan for your pavement, forcing you to spend more on repairs or even a full replacement. Understanding the common mistakes made during the sealcoating process can help you avoid them and ensure you get the most value from your maintenance efforts.
This guide will walk you through the most frequent sealcoating errors and explain how to get the job done right. By the end, you'll know what to look for in a professional service and how to ensure your asphalt stays in top condition for years to come.
Why Proper Sealcoating is Crucial
Before we look at the mistakes, it's important to understand what sealcoating does. A quality sealcoat acts as a protective barrier for your asphalt. It shields the surface from:
- UV Rays: The intense Florida sun can oxidize the binder in your asphalt, making it brittle and prone to cracking.
- Water Intrusion: Rainwater can seep into small cracks, expanding and contracting with temperature changes, which leads to larger cracks and potholes.
- Chemical Spills: Oil, gas, and other vehicle fluids can soften and break down the asphalt.
- Wear and Tear: Regular traffic gradually wears down the surface.
A properly applied sealcoat not only protects the pavement but also gives it a fresh, dark black finish, enhancing your property's curb appeal. But achieving these benefits requires avoiding several common pitfalls.
Top Sealcoating Mistakes to Avoid
1. Inadequate Surface Preparation
One of the most critical errors in the sealcoating process is failing to properly prepare the asphalt surface. Applying a sealant to a dirty or damaged surface is like painting over a dusty, cracked wall—it simply won't stick.
Common Preparation Mistakes:
- Not Cleaning Thoroughly: The pavement must be completely free of dirt, debris, dust, and oil spots. Any contaminants left on the surface will prevent the sealant from bonding correctly, leading to peeling and flaking. A professional team will use high-powered blowers, wire brooms, and sometimes pressure washers to ensure the surface is pristine.
- Ignoring Repairs: Sealcoating is a protective measure, not a structural repair. Applying it over existing cracks, potholes, or alligatoring (interconnected cracks) will not fix them. In fact, it can trap moisture in the cracks, making the problem worse. All cracks should be filled, and potholes repaired before any sealant is applied.
- Failing to Treat Oil Spills: Oil and gasoline spots are particularly problematic. These chemicals repel water-based sealants, creating areas where the coating won't adhere. These spots must be treated with a special primer to ensure proper bonding.
2. Applying Sealant in Poor Weather Conditions
The weather in Lake County, FL, can be unpredictable, but sealcoating requires specific conditions to cure properly. Applying sealant at the wrong time can ruin the entire job.
Weather-Related Errors:
- Applying in Cold Temperatures: Most sealcoating products require ground and air temperatures to be at least 50°F (10°C) and rising for a full 24 hours. Applying sealant in colder weather prevents it from curing correctly, resulting in a weak, non-durable finish.
- Working in Direct, Intense Sunlight: While warmth is needed, applying sealant on an extremely hot day under direct, intense sun can cause it to dry too quickly. This can lead to an uneven finish and potential "tire tracking" marks because the surface hasn't had enough time to cure uniformly.
- Ignoring Rain Forecasts: Rain is the enemy of fresh sealcoat. If it rains before the sealant has had adequate time to cure (typically 24-48 hours), it can wash away the product, leaving a streaky, diluted, and ineffective coating. Always check the forecast for a clear window of at least 48 hours.
3. Using Low-Quality Materials
Not all sealcoating products are created equal. Some contractors try to cut costs by using inferior materials or over-diluting their sealant mix. This directly impacts the longevity and effectiveness of the sealcoat.
Material Mistakes:
- Choosing the Wrong Type of Sealer: There are different types of sealants, including asphalt emulsion and coal tar emulsion. While coal tar is very durable, it has environmental concerns. High-quality asphalt emulsions with performance-enhancing polymers are often the best choice for areas like Lake County, FL, offering excellent protection and flexibility.
- Over-Diluting the Product: Manufacturers provide specific guidelines for adding water and sand to their sealant. Adding too much water thins out the product, reducing its protective qualities and durability. The right amount of sand is also crucial, as it provides slip resistance and helps create a more durable surface.
- Not Mixing Properly: The sealant, water, and sand must be mixed continuously to ensure a consistent, uniform application. If the mixture isn't agitated correctly, the sand can settle, leading to an uneven texture and inconsistent protection across the pavement.
4. Incorrect Application Techniques
Even with perfect preparation and high-quality materials, poor application techniques can lead to a subpar result. The goal is to apply a thin, even coat that provides complete coverage without being too thick.
Application Errors:
- Applying Too Much Sealant: It might seem like a thicker coat would offer more protection, but the opposite is true. A coat that is too thick will not cure properly. It can remain soft underneath and is prone to cracking, flaking, and power steering marks. It's better to apply two thin coats than one thick one.
- Uneven Application: An inconsistent application, often seen with streaking or varying textures, means some areas are getting more protection than others. This can be caused by improper squeegee or spray techniques. Professionals ensure a uniform finish for consistent protection and a better appearance.
- Rushing the Job: Sealcoating requires patience. This includes allowing adequate drying time between coats and before opening the pavement to traffic. Rushing either of these steps will compromise the integrity of the sealcoat.
Protect Your Investment with Professional Sealcoating
Avoiding these common mistakes is the key to a successful sealcoating project that protects your pavement and enhances your property's value. While a DIY approach might seem tempting, the risks of getting it wrong are high. An improperly sealed driveway or parking lot can lead to costly repairs down the line.
Hiring an experienced, reputable contractor is the best way to ensure the job is done right. A professional will have the right equipment, use high-quality materials, and understand the nuances of surface preparation and application, especially in the unique climate of Lake County, FL.
