How to Seal a Driveway Properly? Do It Yourself!

Last Updated on June 19, 2025

Driveway sealing is one of the most crucial maintenance steps to ensure the longevity, durability, and aesthetic appeal of your driveway. Whether your driveway is made of asphalt or concrete, sealing acts as a protective shield against various damaging elements, such as harsh weather conditions, frequent vehicle traffic, chemical spills, and moisture infiltration. Without proper sealing, the driveway surface can deteriorate due to exposure to sunlight, rain, snow, and oil spills, leading to cracks, fading, and structural weaknesses over time. By applying a high-quality sealant, you can extend the lifespan of your driveway, improve its resilience, and enhance your property’s overall curb appeal. If you’re wondering How to Seal a Driveway the right way, this step-by-step guide will help you achieve a smooth, durable finish that protects your driveway for years to come.

Key Benefits of Driveway Sealing

1. Prevents Water Damage

Water penetration is one of the primary causes of driveway deterioration. When moisture seeps into small cracks and crevices in the pavement, it can lead to significant issues, especially in colder climates. During winter, trapped water can freeze and expand, causing the cracks to widen and eventually form potholes. Sealing the driveway creates a waterproof barrier that prevents water from infiltrating the surface, reducing the risk of damage and costly repairs.

2. Minimizes Cracking and Potholes

Over time, driveways are exposed to heavy loads from vehicles, temperature fluctuations, and environmental wear and tear. These factors contribute to the formation of cracks and potholes, which can worsen if left unaddressed. Regular sealing helps reinforce the pavement, preventing small cracks from expanding and transforming into more severe structural issues. By maintaining a sealed surface, homeowners can prolong the life of their driveways and avoid expensive repair work.

3. Shields Against Oil and Chemical Spills

Vehicles often leak fluids such as oil, gasoline, and other chemicals, which can stain and weaken the integrity of a driveway. Unsealed surfaces are more porous, allowing these substances to penetrate deep into the material, causing permanent stains and structural degradation. Sealcoating creates a protective layer that repels chemicals, making it easier to clean spills and maintain the driveway’s pristine condition.

4. Enhances Aesthetic Appeal

A well-maintained driveway contributes significantly to the overall appearance of a property. Over time, asphalt driveways tend to lose their dark, rich color due to oxidation and exposure to UV rays, making them look dull and worn out. Similarly, concrete driveways can develop discoloration and surface imperfections. Sealing restores the original color and provides a smooth, polished look, enhancing the curb appeal of the property. A freshly sealed driveway gives a neat, well-kept impression to visitors and potential buyers if the property is on the market.

5. Protects Against UV Rays and Oxidation

Prolonged exposure to direct sunlight can have a deteriorating effect on asphalt driveways. UV rays break down the binders in asphalt, making the surface brittle and more susceptible to cracking. Oxidation further weakens the material, reducing its flexibility and structural integrity. Sealcoating acts as a sunscreen for the pavement, preventing UV-induced damage and slowing down the oxidation process. This protection extends the driveway’s lifespan and maintains its structural strength for years to come.

6. Reduces Long-Term Maintenance Costs

Preventive maintenance is always more cost-effective than major repairs or complete driveway replacements. Driveway sealing is a proactive approach to extending the life of the pavement while minimizing repair expenses. A properly sealed driveway is less prone to damage, meaning homeowners can avoid costly fixes associated with deep cracks, potholes, and surface erosion. Investing in regular sealcoating can save thousands of dollars in long-term maintenance.

7. Improves Surface Smoothness and Cleanliness

A sealed driveway has a smoother, more uniform surface, making it easier to clean and maintain. Dirt, debris, and stains are less likely to penetrate a sealed surface, allowing for quick and effortless cleaning. Whether sweeping, pressure washing, or using a leaf blower, maintenance is far more manageable when the driveway has a protective sealant.

8. Prevents Weed Growth and Vegetation Intrusion

Unsealed driveways are more vulnerable to weed growth, as small cracks and gaps in the pavement provide an ideal environment for weeds and grass to sprout. These invasive plants can further widen cracks, leading to more significant structural problems. Applying a sealant prevents vegetation from taking root, reducing the need for constant weed removal and keeping the driveway looking well-maintained.

Common Driveway Sealing Mistakes to Avoid

Sealing your driveway is an important maintenance task that protects it from weather damage, stains, and daily wear. However, many homeowners unknowingly make mistakes during this process, which can compromise the effectiveness and lifespan of their driveway sealant. Here are some detailed explanations of common errors and how you can avoid them:

1. Applying Sealant Too Early

Newly paved driveways need adequate time to cure before sealing. Typically, asphalt driveways require a curing period of 6 to 12 months, whereas concrete driveways might take slightly longer. Applying sealant prematurely traps moisture and oil residues within the material, preventing it from properly curing. This leads to weak adhesion, surface deterioration, and a shorter lifespan for your driveway. To avoid this, ensure your driveway has completely cured and consult your paving contractor if unsure about timing.

2. Sealing Too Often

While sealing is beneficial, doing it excessively can cause more harm than good. Over-sealing creates thick layers that eventually crack, peel, and deteriorate due to buildup. The ideal timeframe for resealing your driveway is typically every 2-3 years, depending on the climate and traffic. Pay attention to visible signs of wear instead of automatically resealing annually. Properly timed sealing will effectively protect your driveway without damaging it.

3. Sealing Over Existing Damage

Simply applying sealant over existing cracks, potholes, or damage provides only a superficial solution. Underlying issues remain unresolved and tend to worsen over time, causing the sealant to crack and degrade faster. Before sealing, thoroughly inspect your driveway and repair any damage—filling cracks and holes, addressing structural issues, and ensuring the surface is clean and level. This preparation ensures that your sealant adheres properly, providing long-term protection.

4. Ignoring Weather Conditions

Weather significantly impacts the effectiveness of driveway sealing. Ideal conditions include temperatures ranging between 50-90°F (10-32°C), with clear, dry weather forecasted for at least 48 hours. High humidity, rain, extreme heat, or freezing temperatures can prevent the sealant from curing correctly, resulting in uneven sealing, cracking, or peeling. Always check the weather forecast in advance and choose optimal conditions for your sealing project.
