Avoiding Costly Sealcoating Mistakes: Tips to Save Time and Money

Sealcoating is essential for maintaining asphalt surfaces and improving their longevity and appearance. However, mistakes during the sealcoating process can lead to inefficiencies, wasted materials, and dissatisfied customers. Whether you’re an industry veteran or just starting, understanding and avoiding common errors can improve your results and profitability.

1. Neglecting Proper Surface Preparation

Failing to adequately clean and prepare the surface before sealcoating can result in poor adhesion, leading to premature wear and peeling.

How to Avoid It:

Thoroughly sweep and clear the surface of dirt, debris, and loose materials.
Use a degreaser or power washer to remove oil stains and grime.
Allow the surface to dry completely before applying the sealcoat.
Patch and repair any existing cracks or potholes before sealcoating.

2. Incorrect Sealcoat Application Thickness

Applying a sealcoat too thick or too thin can impact the durability and longevity of the sealcoating job.

How to Avoid It:

Follow manufacturer recommendations for the correct application thickness.
Apply in two thin coats rather than one thick layer for optimal results.
Utilize the appropriate sprayer or squeegee to achieve even distribution.

3. Disregarding Weather Conditions

Applying a sealcoat in unfavorable weather can cause improper curing, leading to application failure.

How to Avoid It:

Always check the weather forecast before scheduling jobs.
Avoid applying a sealcoat if rain is expected within 24 hours.
Ensure the temperature is at least 50°F (10°C) and rising for proper curing.
Consider humidity levels, as excessive moisture can extend drying times.

4. Using Inferior or Over-Diluted Sealcoat

Cutting corners with low-quality or improperly mixed sealcoat can compromise the effectiveness and longevity of the application.

How to Avoid It:

Invest in high-quality, commercial-grade sealcoating materials.
Follow manufacturer guidelines on mixing ratios.
Avoid over-diluting with water, as this reduces the protective qualities of the sealcoat.

5. Inadequate Mixing of Sealcoat

Failing to properly mix sealcoat before application can lead to inconsistent coverage and weak performance.

How to Avoid It:

Use mechanical agitation or power mixing to maintain uniform consistency.
Regularly stir the mixture, especially when using large storage tanks.
Ensure sand additives and other components are evenly distributed.

6. Ignoring Crack Repairs Before Sealcoating

Applying sealcoat over untreated cracks will not prevent water penetration, leading to further pavement damage.

How to Avoid It:

Fill cracks with quality crack filler before sealcoating.
Allow proper curing time for crack filler before applying sealcoat.
Utilize routing machines for deeper cracks to enhance adhesion.

7. Using Inappropriate or Poorly Maintained Equipment

Faulty or incorrect equipment can cause uneven application and wasted materials.

How to Avoid It:

Invest in high-performance spray systems and squeegees.
Regularly inspect and clean equipment to prevent clogs and malfunctions.
Utilize power agitation for consistent mixing during application.

8. Rushing the Drying and Curing Process

Allowing insufficient drying time can result in peeling, tracking, and compromised durability.

How to Avoid It:

Allow at least 24-48 hours for the sealcoat to cure before reopening to traffic.
Use barricades and signage to prevent premature use.
Educate clients on recommended drying times and post-application care.

9. Inadequate Traffic Control

Failing to block off sealed areas properly can result in accidental damage to the fresh sealcoat.

How to Avoid It:

Mark and barricade work zones.
Inform property owners, tenants, and stakeholders of restricted access periods.
Use cones, caution tape, or temporary barriers to prevent premature traffic exposure.

10. Neglecting Regular Equipment Maintenance

Improperly maintained equipment can cause operational inefficiencies and poor application results.

How to Avoid It:

Clean sprayers, hoses, and tanks after each use to prevent buildup and clogs.
Conduct routine inspections for leaks, worn-out parts, and obstructions.
Replace spray tips and filters as needed for consistent application performance.
