Sealcoating is a crucial step in protecting and extending the life of asphalt surfaces. It prevents moisture penetration, shields against UV rays, and improves aesthetic appeal. However, even the best sealcoat can face issues like peeling and flaking if not applied or maintained properly.
Want to ensure your sealcoat stays smooth and durable? This guide will walk you through the most common causes of peeling and flaking and offer actionable tips to keep your asphalt looking flawless for years.
Before solving the problem, we need to understand what causes it. Peeling and flaking can occur due to a variety of reasons, including asphalts' condition, improper surface preparation, or even environmental factors.
Sealcoat relies on a strong bond with the asphalt surface. If the surface isn't prepared properly, such as cleaning off dirt, oil, or debris, the sealcoat won't adhere as intended. A dirty or oily surface acts as a barrier between the asphalt and the sealcoat, leading to weak adhesion and eventual peeling.
Key Example: If heavy oil stains aren’t cleaned, the sealcoat layer applied on top of those spots will quickly break down and separate from the asphalt.
Moisture is one of the worst enemies of your sealcoat. Trapping water underneath the sealcoat layer can prevent it from setting correctly, resulting in flaking and bubbling over time.
Sealcoat needs specific weather conditions to cure properly. High humidity, cool temperatures, or extreme heat can all negatively impact the application process. If applied during suboptimal weather, the sealant may fail to bond uniformly.
While it might seem like applying extra layers of sealcoat ensures better protection, overdoing it can cause cracks and peeling. Each layer must adequately bond with the previous one—too thick or numerous coatings can weaken the structural integrity.
Not all sealcoat products are created equal. Low-quality or improperly mixed sealants can break down quicker and are more prone to peeling, leaving asphalt surfaces vulnerable to damage.
The good news? Peeling and flaking are entirely preventable with the right techniques and precautions. Follow these steps to ensure your sealcoat stays intact and effective.
Start with a spotless surface. Remove debris, dirt, and oil stains before applying the sealcoat. Pressure washing is an effective way to clean large areas of asphalt thoroughly. For stubborn oil stains, use specialized degreasers to break down the residue.
Make sure the surface is completely dry before moving forward.
Sealcoat is not a replacement for proper asphalt repair—it should only be applied on a structurally sound surface. Cracks and potholes should be filled, and major damages must be repaired before sealcoating.
For example, a crack filler or patching compound can be used to fix damaged sections. Once repairs are complete, wait for the recommended curing time before moving to sealcoating.
Weather dictates your sealcoat’s success. Always choose a day when the temperature is between 50-90°F (10-32°C) with no rain in the forecast. Low humidity is ideal for curing.
It’s best to sealcoat early or late in the day when surface temperatures aren’t excessively hot, as heat can cause uneven curing or rapid drying.
Invest in a high-quality sealcoat product that’s appropriate for your specific needs (e.g., residential driveways, commercial parking lots). Work with trusted suppliers to ensure you’re getting materials designed to perform well and resist weathering.
Look for products with uniform viscosity and well-balanced ingredients to ensure durability. If mixing the sealcoat yourself, follow the manufacturer’s instructions carefully to avoid a poor mix.
When it comes to sealcoating, less is often more. Apply the product in thin, even layers to promote proper bonding and curing. If additional protection is needed, applying multiple thin coats (after each has dried) is far better than a single thick coat.
Use appropriate equipment such as squeegees or spray systems to ensure even coverage. Incorrect application tools can create clumping or streaking, which weakens adhesion, leading to potential flaking.
Patience is key! Sealcoat needs sufficient time to fully dry and harden. Refer to the product’s guidelines, but as a general rule, allow 24-48 hours for drying and up to a week for complete curing before permitting vehicle traffic.
Placing barricades or signs to keep traffic off newly sealed areas is an effective way to prevent premature wear and tear.
Keep your asphalt free of debris and oil stains to extend your sealcoat’s lifespan. Sweeping and occasional pressure washing can keep the surface pristine.
Address cracks, potholes, or other damages early to prevent them from worsening. Scheduling periodic inspections can help detect issues before they cause peeling in your sealcoat.
Sealcoating isn’t a one-time process. Generally, it’s recommended to reseal every 2-4 years depending on the level of wear and tear. This ensures that your asphalt remains protected and smooth.
Preventing peeling and flaking in your sealcoat is about proper preparation, using quality materials, and taking the time to apply the product under ideal conditions. Following the steps outlined above will not only extend the life of your asphalt but also save you money in the long run.
The key to a smooth, lasting sealcoat lies in attention to detail and consistent maintenance. With proper care, your asphalt can remain durable and attractive for years to come.
